Allometric scaling and floral size variation in Collinsia Allometric scaling theory has previously been used to estimate the functional relationship between two biological variables. In addition to parameter estimation, deviations from the general scaling relationship can be used to create hypotheses. Here, I explore deviations from the allometric scaling pattern for plant and floral size within the genus Collinsia on three levels: among species, within species, and among populations of a single species. Collinsia species are self-compatible annual herbaceous plants that have been shown to vary in floral size, autonomous fruit production, and estimated mating system. I quantified the amount of variation in characteristics related to plant mating systems: floral size and autonomous fruit production in a pollinator-free environment and used variation and scaling deviations to generate expectations about environmental selection pressures. I found that the scaling relationships differed on each of the three levels and that deviation from the general floral size-plant size relationship is common within this genus. The among-species regression explained only 20% of the variation in floral size, and species- and population-level regressions explained even less. The four species for which I obtained controlled environment estimates of vegetative and floral trait in this study differed significantly in autonomous fruit production, floral size, and plant size, while populations of C. heterophylla differed in floral and plant characteristics, but not autonomous fruit production. In addition, variation in plant size characteristics was 50-66% greater than variation in floral size characteristics suggesting selection to reduce variation in floral size and flexibility in plant size. Autonomous fruit production was correlated with floral size in C. tinctoria, with floral number in C. verna, and uncorrelated in C. heterophylla suggesting that the ability to self-fertilize varies among species. Using a comparative method and investigating factors correlated with plant mating system, such as floral traits, across a group of closely related species provides new insights into factors affecting their variation |

Analysis of intraspecific and interspecific interactions between the invasive exotic tree-of-heaven (Ailanthus altissima (Miller) Swingle) and the native black locust (Robinia pseudoacacia L.) Invasive exotic plants can persist and successfully spread within ecosystems and negatively affect the recruitment of native species. The exotic invasive Ailanthus altissima and the native Robinia pseudoacacia are frequently found in disturbed sites and exhibit similar growth and reproductive characteristics, yet each has distinct functional roles such as allelopathy and nitrogen fixation, respectively. 1) A four-month full additive series in the greenhouse and 2) spatial point pattern analysis of trees in a silvicultural experiment were used to analyze the intraspecific and interspecific interference between these two species. In the greenhouse experiment, total biomass responses per plant for both species were significantly affected by interspecific but not by intraspecific interference (p <0.05). Competition indices such as Relative Yield Total and Relative Crowding Coefficient suggested that A. altissima was the better competitor in mixed plantings. Ailanthus altissima consistently produced a larger above ground and below ground relative yield while R. pseudoacacia generated a larger aboveground relative yield in high density mixed species pots. However, R. pseudoacacia exhibited more variation for multiple biomass traits, occasionally giving it an above ground advantage in some mixed species pots. Analysis of spatial point patterns in the field with Ripley's K indicated that the two species were positively associated with each other along highly disturbed skid trails in the majority of the field sites. Locally, increased disturbances could lead to more opportunities for A. altissima to invade, negatively interact with R. pseudoacacia (as was evident in the greenhouse study), and become established in place of native species |

Antifeedant effects of diethyl toluamide and neem oil on native cave weta, cockroaches, and amphipods / The antifeedant effects of both diethyl toluamide (DEET) and neem oil added at concentrations of 0.2% to cereal-based baits used for vertebrate pest control in New Zealand were investigated with three taxa of native invertebrates known to eat these baits. DEET reduced the numbers of captive cave weta and cockroaches feeding on treated non-toxic baits, but neem oil did not. Cinnamon oil, routinely added to bait used for possum control, also failed to reduce the numbers of captive cave weta and cockroaches feeding on treated non-toxic baits. Captive amphipods were not observed feeding on treated or untreated baits. Further tests are needed to confirm both the palatability and efficacy of toxic baits containing DEET to possums, rats, and mice, and the antifeedant effects of toxic baits containing DEET on invertebrates in the field. The environmental fate of DEET will also need to be investigated before it can be added routinely to baits used for control of possums and rodents in New Zealand |

Bait station preferences of Norway rats / |
|
|
Bait station preferences of ship rats / Department of Conservation (DOC) surveillance programmes to detect rodent invasions on rodent-free islands currently involve observation of rodent interference with toxic baits in bait stations. Different DOC Conservancies use different types of bait station. We monitored the behavioural responses of 24 wildcaught captive ship rats (Rattus rattus) to four currently used bait station types; yellow plastic pipe, wooden box ("rat motel"), wooden tunnel, and white plastic Philproof bait stations. The bait stations contained non-toxic bait similar to the toxic bait used in surveillance programmes. More than 75% of the rats entered the yellow plastic pipe, wooden box, and wooden tunnel bait stations, but fewer than 10% entered the Philproof bait stations. Rats ate bait from the first three bait station types but not from the latter. The average amount of bait eaten per night by the rats that ate bait (0.8 g) was not enough for a lethal dose for 50% of the population if the baits had contained 20 ppm, or even 50 ppm, brodifacoum. On the basis of these results, DOC should use yellow plastic pipe, wooden box, or wooden tunnel bait stations rather than Philproof bait stations for surveillance for ship rats. However, other bait station types and the responses of kiore (R. exulans) and house mouse (Mus musculus) to different bait stations should be tested before any final decision is made on the best type to use in multispecies rodent surveillance programmes |

Brockman memorial tree tour About 480 different kinds of trees beautify the University of Washington campus. Only twenty-eight are species native on campus. Since before the turn of the century, forestry professors, botanists, gardeners, and landscape architects have planted native and non-native trees for decoration and education. The campus community views trees as valuable resources, studies their ecological roles, and admires their fascinating variations and seasonal transformations. This tour is an online adaptation of the original tour designed by Suzanne Hellmuth and Jock Reynold. It introduces you to the great green realm of a campus renowned for its lovely landscape |

Bryophytes, lichens, and dead wood in young managed boreal forests / In adjoining young and old forest stands, red-listed bryophytes and lichens were more abundant in the old stands. This difference disappeared when the amount of substrate available was taken into account. When the young stands were positioned north of the old, the bryophytes were equally frequent in both forest stages, indicating that the aspect of a clearcut matters. In conclusion, young forests have the potential to host a high diversity of species. Research on young natural and managed forests is needed to formulate science-based conservation strategies in managed forest landscapes |

Deer impacts on tawa (Beilschmiedia tawa) regeneration / Tawa (Beilschmiedia tawa) is the predominant canopy tree species in extensive tracts of old-growth forest across much of the North Island, New Zealand. The regeneration of this slow-growing, late-successional species is crucial for canopy maintenance in these forests. The impacts of herbivory on tawa regeneration were assessed in tawa-dominant forests in the North Island. There was no significant change in seedling densities between 1997 and 2006 in 31 permanent plots at Otamatuna in northern Te Urewera National Park, despite intensive red deer (Cervus elaphus) control during this period. Similarly, the exclosure of deer from two larger plots over a similar period in the same area did not affect tawa seedling density. Seedling densities in 15 subplots of large permanent plots elsewhere in the region were not correlated with deer history, which varied from never present to c. 50 years of presence. Seedling populations of thousands per hectare are probably adequate to maintain tawa at current densities; however, populations of hundreds of seedlings per hectare may not be. Established seedling densities in northern Te Urewera National Park were relatively low, ranging from 500 to 1250 per hectare, suggesting there may be cause for concern there. Furthermore, seedling populations declined by 16%-82% over 22-40 years in four of the permanent subplots. Although the data analysed here did not implicate deer herbivory in these declines, previous exclosure studies over longer periods in the same region did. The overall impression from the equivocal results reviewed here is that herbivory may be impairing tawa regeneration in some places. Recommendations are made for further research requirements |

Ecology and management of morels harvested from the forests of western North America / Morels are prized edible mushrooms that fruit, sometimes prolifically, in many forest types throughout western North America. They are collected for personal consumption and commercially harvested as valuable special (nontimber) forest products. Large gaps remain, however, in our knowledge about their taxonomy, biology, ecology, cultivation, safety, and how to manage forests and harvesting activities to conserve morel populations and ensure sustainable crops. This publication provides forest managers, policymakers, mycologists, and mushroom harvesters with a synthesis of current knowledge regarding these issues, regional summaries of morel harvesting and management, and a comprehensive review of the literature |

Ecology and taxonomy of Leptosphaerulina spp. associated with turfgrasses in the United States Leptosphaerulina spp. are common fungi that have been reported to colonize several turfgrass species. Controversy exists regarding the relationship of Leptosphaerulina spp. and their turfgrass hosts. The fungus has been classified as a saprophyte, senectophyte, weak pathogen, and pathogen of turfgrasses. There has also been conflicting reports regarding the delineation of species within the genus Leptosphaerulina. Because of the uncertainty regarding the ecology and taxonomy of the genus in relation to turfgrasses the present study was undertaken. The ITS and EF-1[alpha] gene regions were sequenced and analyzed to compare to the multiple taxonomic schemes reported in the literature. The ITS region offered no resolution of species; however, the phylogeny of the EF-1[alpha] gene was consistent with the six-species model of Graham and Luttrell. Inoculation experiments were performed on unstressed and artificially stressed plants to determine whether the fungi are pathogens, senectophytes, or saprophytes of turfgrasses. Perennial ryegrass and creeping bentgrass plants were stressed by placing them in a dew chamber set at 380C, 100% R.H., and no light for two and one days respectively. Plants were inoculated with cultures of Leptosphaerulina isolated from turfgrasses, and maintained at optimum conditions reported for infection and colonization. There was no visible difference between inoculated and uninoculated plants, and examination of cleared and stained leaves with a light microscope revealed spores that germinated and produced appressoria, but failed to penetrate the epidermal cells. The lack of infection and colonization suggests that Leptosphaerulina spp. are saprophytes of turfgrasses |

effect of elephant utilisation on the Sterculia rogersii and Adansonia digitata populations of the Kruger National Park This study assesses elephant induced damage and mortality of baobab and common star-chestnut trees in the northern Kruger National Park. Comparisons are made between the populations north and south of the Luvuvhu River. The density, population size and age structure are estimated. The population structure of neither species has been shaped by elephant utilisation. While the baobab population has a healthy age distribution, that of the star-chestnut population shows that recruitment has declined in recent decades. Utilisation has been found to be higher in the south as a result of higher elephant densities, although recently damage has been greater in the north. Damage increases with tree size. The mortality of baobabs is lower than in other areas where elephants and baobabs co-exist. Elephants are not playing a significant role in mortality of either tree species and management of factors other than elephant is required to improve regeneration rates of these species |

Estimating the benefit of early control of all newly naturalised plants / Early eradication of weeds is preferable to attempting to control them when they are well-established, and becoming a problem. But when a plant is newly naturalised, we often do not know if it will eventually become a weed. In this study, we compare the cost effectiveness of removing all newly naturalised plants early or delaying action until they prove to be weeds. We obtained data from 58 Department of Conservation weed control projects around New Zealand and used these data to compare the typical cost for controlling a weed infestation at two stages of invasion: early stage small infestation, and late stage large infestation. We also modelled weed spread using different scenarios of plant growth rate and dispersal plus typical time estimates for weed infestations to spread. We then analysed the control costs at 5, 10, 20 and 40 years from establishment, to predict the cost implications of delaying weed control. Our data suggest that, early on, while an infestation is small (only a few plants or plants covering an area up to 400 m2), all individuals can be easily removed for a minimal cost--an average of $1090. By contrast, if control is postponed until a later stage (when the infestation is widespread or dense) it is, on average, 40 times more expensive than early removal. Furthermore, it is shown that if a plant's weed potential is unknown, its early removal will still be beneficial if removal can be achieved for less than $7000. Once a weed disperses from its initial establishment point, the costs of control increase dramatically, largely because of the burgeoning cost of searching for individual plants |

Field survey of growth and colonization of nonnative trees on mainland Alaska / Six of nine nonnative boreal conifers in three genera (Abies, Larix, and Pinus) regenerated in 11 to 31 years after they were introduced to mainland Alaska. Lodgepole pine (Pinus contorta var. latifolia Engel.) and the Siberian larches (Larix sibirica Ledeb. and L. sukaczewii N. Dyl.) were the most widely introduced species and will likely be the first nonnative conifers to naturalize. Siberian larch grew up to six times more stem volume than white spruce in the first 40 years on upland sites, but was susceptible to the larch sawfly and a blue stain pathogen carried by bark beetles. On productive sites, lodgepole pine appeared to grow more stem wood than white spruce for about 35 years after planting. Snowshoe hares and moose were the most serious pests of the nonnative conifers. Balsam fir (Abies balsamea (L.) Mill.) was the only species to regenerate in an established moss understory. Growth and age relationships were negative for all adequately sampled nonnative conifers and positive for native white spruce (Picea glauca (Moench) Voss). Data were insufficient to assess niche availability for commercial use of productive nonnative conifers in mixed stands in Alaska. Survey results indicate that introduction and naturalization of noninvasive tree species may improve the diversity, stability, and productivity of managed forest ecosystems |

Fire-induced changes to the vegetation of tall-tussock (Chionochloa rigida) grassland ecosystems / The deliberate use of fire has long been a contentious issue in the South Island high country of New Zealand, being seen by some as damaging to the environment and by others as an essential pastoral management tool. These issues were examined in tall-tussock (Chionochloa rigida) grasslands at two sites in Otago, which were burned either in spring, to simulate pastoral management practice, or late summer, to simulate accidental fires. Fire temperatures reached over 10000C, but were of short duration (4-8 minutes) and had little heating effect on the soil. Biomass, carbon, and nutrient losses were lowest when the grasslands were burned under damp conditions, and increased as soil and plant moisture levels declined. The best predictors of biomass loss were the moisture content of the top 5 cm of soil and the base of the tussocks. Spring burns under damp conditions killed c. 35% of the tussock tillers but did not cause the death of tussocks, whereas burns under drier conditions or later in the growing season killed over 75% of tussock tillers and resulted in the death of tussocks. Seedling densities and inflorescence production were also least affected when the grasslands were burned under damp spring conditions; when conditions were drier, both were dramatically reduced and showed little sign of returning to pre-burn levels 4-5 years after the fire. Early season burns under damp conditions posed little threat to the long-term survival of tall-tussock ecosystems, whereas fires later in the season, or when conditions were drier, resulted in substantially greater biomass, carbon and nutrient losses and caused a loss of tussock dominance, at least in the short to medium term. Therefore, minimising their extent should be a priority wherever tussock cover is to be retained |

Grassland plant diversity in relation to historical and current land use / About 150 years ago agriculture was drastically reformed and around 90% of the formerly vastly distributed semi-natural grasslands, i.e. unfertilised and uncultivated grasslands, have since then disappeared. Accordingly, grassland plant diversity has declined due to abandonment, changed management methods and habitat loss. Grasslands are species rich as a result of a long management history; the management providing niches for a variety of organisms. Current diversity patterns are thus a result of historical and current land use in combination. This thesis explores some of the connections between historical land use and grassland vascular plants. Two studies concerns the habitat level, i.e. local conditions for grassland plants, two studies the landscape level, i.e. habitat patches in relation to neighboring patches. In the first study, grassland plant diversity was found to be strongly correlated to 18th and 19th century land use, more so than to current land use. Furthermore, the particular sequence by which one land use changed into another from the 18th century until the mid 20th century was an important predictor of plant diversity. In the second study, detailed comparison of 18th century and current grassland management revealed that current grassland management lacks several ecological factors that the literature deems important for grassland plant reproduction. The third and the fourth study explore how plant species richness in specific grasslands is related to the surrounding landscape by studying how current, 19th and 20th century grassland connectivity and area are reflected in current species richness of grassland plants. They revealed that the response of grassland plant diversity to different fragmentation components can differ widely between two superficially similar landscapes, although historical components were important in both landscapes for explaining current diversity patterns. Moreover, the direction of livestock movement within the pre-industrial landscape appears to have been an important determinant regarding the functional connectivity between different grassland patches. Given the strong correlation between historical agricultural practices and current plant diversity patterns, this thesis discusses this diversity as a biocultural heritage. The historical aspects of grassland diversity ought to be taken into account in conservation and restoration measures |

Impact of domestic stock on vegetation in South Westland, 1989-2004 / This long-term study aimed to determine the effect of domestic stock (particularly cattle) grazing on forest margin plant communities in South Westland, New Zealand. Between 1989 and 1992, six pairs of matched exclosure and control plots were established across forest-grassland boundaries on river flats grazed by cattle. These were resurveyed at intervals of 3-5 years. Short-term (8-13 years) vegetation responses to stock exclusion varied with community type in both rapidity and direction. Fencing reduced the number of all herbs, particularly in floodplain grassland habitats, and increased the cover of exotic herbs. Fencing appeared to promote establishment of Nothofagus menziesii seedlings and saplings in forest habitats, but may have suppressed woody seedling establishment in ecotone habitats. The number of shrubs preferred by stock only increased with fencing or between measurements in some locations, suggesting that previous or ongoing grazing by mammals other than domestic stock was continuing to have an impact. Fencing increased tree fern numbers in forest habitats. The results clearly showed that the effect of excluding stock was variable. In part, this was due to indirect competition effects of weeds and the impacts of other browsing animals. Manipulative experiments are required to disentangle the direct effects of cattle grazing from those of other animals. A survey of local grazing concessions in the vicinity of each exclosure is needed to determine how representative these sites are of grazed forest margin vegetation in South Westland, and thus how widely predictions about the effects of grazing exclusion based on them might be applied. Maintenance of native herb species diversity in grasslands can be compatible with low-intensity grazing; however, maintenance of woody regeneration in many ecotone forest types is not compatible with grazing. Therefore, no one approach can be applied in all situations and site-specific information is required for conservation management |

influence of dense understory shrubs on the ecology of canopy tree recruitment in southern Appalachian forests Suppression of canopy tree recruitment beneath rapidly spreading thickets of Rhododendron maximum L. (Ericaceae) in southern Appalachian forests is an issue of major concern because of the potential impacts on forest productivity, hydrology and wildlife habitat. Many studies have investigated the causes of seedling inhibition beneath dense shrub understories, but few have uncovered specific mechanisms leading to seedling decline. In this study, I have examined the influence of the evergreen understory (R. maximum and Kalmia latifolia L.) on tree recruitment processes at multiple stages - seed rain, seed bank, and post-establishment seedling growth and survivorship. Effects of dense shrub cover on seed rain and seed bank density and composition were examined using a paired treatment design in which samples were collected beneath shrub-influenced and open understories. A second experiment investigated the influence of R. maximum and K. latifolia density on the growth and survivorship of Quercus seedlings, resource availability, and the rates/causes of seedling damage. I found that neither seed rain, nor seed bank density or species richness was inhibited by the presence of R. maximum or K. latifolia. Forest seed banks were dominated by sweet birch (Betula lenta L.), and were compositionally disparate from the overstory. Analysis of resource competition between shrubs and seedlings indicated that seedling performance and survivorship was a negative function of R. maximum density. Open-canopy light availability, nitrogen content in the organic horizon (litter and humus), and soil nutrient availability were potential resource-related mechanisms. Further, I found that the rates of insect herbivory on Quercus seedlings were positively correlated with R. maximum density. Kalmia latifolia had little influence on resource availability, seedling performance or herbivory rates, and does not appear to have a suppressive effect on tree seedlings. Overall, this research indicates that resource competition is the primary mechanism by which seedling suppression occurs beneath R. maximum, and that increased herbivory on seedlings may be an additional mechanism that demands further study |

Insect biodiversity and dead wood : proceedings of a symposium for the 22nd International Congress of Entomology / Dead wood is anything but dead. It is the lifeblood of an intricate web of life in which insects figure prominently. The papers presented here consider the basic ecology and evolutionary history of saproxylic (dead-wood dependent) insects, and show how these species can be affected by human management of the forests where most of them live. Past management has not always been kind to saproxylic insects, and in some parts of the world this has harmed the fauna significantly. However, there is reason to think that continued research may in the future give land managers the technical tools to accommodate saproxylic insects. Whether societies will adopt these friendlier techniques remains to be seen, but we hope the information presented in this volume will encourage them to do so"--Pref |

Lichen bioindication of biodiversity, air quality, and climate : baseline results from monitoring in Washington, Oregon, and California / Lichens are highly valued ecological indicators known for their sensitivity to a wide variety of environmental stressors like air quality and climate change. This report summarizes baseline results from the U.S. Department of Agriculture, Forest Service, Forest Inventory and Analysis (FIA) Lichen Community Indicator covering the first full cycle of data collection (1998-2001, 2003) for Washington, Oregon, and California. During this period, FIA conducted 972 surveys of epiphytic macrolichen communities for monitoring both spatial and long-term temporal trends in forest health. Major research findings are presented with emphasis on lichen biodiversity as well as bioindication of air quality and climate. Considerable effort is devoted to mapping geographic patterns and defining lichen indicator species suitable for estimating air quality and climate |

Management and conservation of seagrass in New Zealand : an introduction / Globally, seagrass management and conservation have received increased attention over the last decade. To date, however, there has been a paucity of available information specific to New Zealand about seagrass beds as an ecosystem component and which could be used to assist resource managers in decision making. This report has been prepared primarily for coastal resource managers, to assist in the management and conservation of seagrass. It provides a review of the current state of knowledge in New Zealand, within the context of international seagrass research. There are some key characteristics that set New Zealand seagrass habitat apart from many temperate and tropical systems. In New Zealand, the seagrass flora is represented by one genus, Zostera, in the family Zosteraceae. Seagrass occurs predominantly intertidally in New Zealand, although it may extend into the shallow subtidal areas of sheltered estuaries, and permanently submerged beds of seagrass have been recorded around a small number of offshore islands. While a lot is known about seagrasses in other regions, the role that these plants play and just how important they are in estuarine and coastal ecosystems in New Zealand is less well understood and to date has been the subject of limited study. The relative importance or magnitude of the multiple ecosystem functions of seagrass beds may vary considerably within and between different estuarine and coastal systems. For successful management, a specific understanding of seagrass ecology within New Zealand is required, preferably at the regional or estuary scale, rather than relying on international paradigms |

Molecular detection and pathology of the oomycete Albugo candida (white rust) in threatened coastal cresses / This study describes the development and testing of a PCR-based assay for the detection of the internal transcribed spacer region 1 (ITS 1) of the ribosomal DNA (rDNA) of Albugo candida. Similar PCR-based approaches have become widely used to detect Albugo spp. and other fungi within plant tissue. Primers were designed based on differences in the ITS 1 sequences between A. candida and Lepidium oleraceum. The primers preferentially amplified the A. candida ITS 1 from tissue samples in which the plant ITS 1 template predominated. Albugo candida ITS 1 DNA was detected in symptomatic host tissue as well as in a number of asymptomatic plants collected from Auckland Regional Botanic Gardens, New Zealand. Albugo candida ITS 1 DNA was also detected in surface-sterilised seed of L. oleraceum. These findings suggest that in the native host L. oleraceum, A. candida can exist as a latent asymptomatic infection and can also be transmitted vertically through seed. With more development, this technique will have the ability to detect Albugo in wild and ex situ populations, and could assist in efforts to ensure that wild stocks are not placed at risk by contamination from restoration plantings. However, because the possibility of false negatives has not been eliminated, further research is required to ensure unambiguous detection. A study on the impact of A. candida infection on plant growth and mortality in L. oleraceum seedlings failed to conclusively demonstrate that the pathogen imposes a significant fitness cost. Further studies are required, including growing seedlings through to reproductive maturity and assessing performance in the field, before firm conclusions can be reached |

Palatability and efficacy of Pestoff 20R bait on mice from Mokoia Island, Rotorua / Following an unsuccessful eradication attempt on mice (Mus musculus) on Mokoia Island, the palatability of the bait used and mouse tolerance to anticoagulants were raised as possible reasons for the operation's failure. To alleviate these concerns before another eradication attempt, a two-choice trial was carried out on 21 mice from Mokoia to compare the palatability of Pestoff 20R to a standard diet. A no-choice trial was also run to assess bait efficacy. A high degree of variability was recorded between individual mice, but in general, mice found Pestoff 20R significantly less palatable than the standard diet. No evidence for tolerance to brodifacoum could be found. The absence of information on dietary preferences and reasons that several mouse eradication attempts have failed are discussed and recommendations are made for the need to test the palatability of a range of bait types in a natural situation. Research on the impact of social interactions on the success of eradication attempts is also recommended |

Public attitudes to pest control : a literature review / This report reviews research concerning public attitudes to vertebrate pest control. The review was confined to attitudes towards introduced, vertebrate pest species and their control through manual, poison or biological control methods. Biological controls include those which occur naturally (i.e. viruses, parasites, predators), and biotechnological controls (i.e. those which involve aspects of genetic engineering). Findings suggest public attitudes concerning control methods can be characterised by three attributes: specificity, humaneness, and degrees of uncertainty. Overall, there is a clear preference for manual methods, considered to be the most humane and specific, while poisons (specifically 1080) fail to satisfy any of the three criteria and are the least acceptable of all methods reviewed. Biological controls, whilst viewed positively for their specificity and humaneness, do not receive total and unconditional support in pest control. Future research in this area needs to examine how the Department of Conservation engages and consults with communities about pest control issues and investigate changes in public attitudes over time. Consideration also needs to be given to demographic differences throughout New Zealand's increasingly culturally diverse population. Attitudes toward the use of biological controls, especially biotechnological, require further investigation |

Recruitment of Coprosma wallii at Paengaroa Mainland Island / This study examined recruitment of the threatened shrub Coprosma wallii at Paengaroa Mainland Island, Mataroa, New Zealand. This is the first comprehensive survey of recruitment of C. wallii seedlings in the North Island. Superficially, Paengaroa appears to offer ideal conditions for C. wallii seedling recruitment. However, the population at Paengaroa appeared to have a scarcity of seedlings and young plants. The present study quantified seedling density and determined which factors might be hindering seedling recruitment. An intensive search was made for seedlings around 21 mature female C. wallii plants: 9 inside the main reserve and 12 on adjacent land that was exposed to weed control. Seedlings were present in four of these plots, with the numbers of seedlings per plot ranging from 1 to 50. The distribution of seedlings strongly suggests that germination and growth take place in areas of disturbance and high light levels, as there were very few seedlings in parts of the forest that were established, with low disturbance and dappled light. It is concluded that C. wallii requires a number of conditions for germination, including high light levels, ground disturbance, moisture and fertile soils. Recommendations are made for further monitoring of seedling recruitment including quantitative measurement of environmental drivers; adaptive management to improve recruitment through spray trials, planting of cultivated seedlings and pulsed grazing regimes; the inventory of a third population; and use of dendrochronlogy to establish population age structures |

review of the current knowledge of rodent behaviour in relation to control devices / A recent review of techniques used to detect and control the four introduced rodent species found on the New Zealand mainland and islands (house mice Mus musculus, ship rats Rattus rattus, Norway rats Rattus norvegicus and kiore Rattus exulans) identified the need for better understanding of rodent behaviour. This report provides a review of the published literature on rodent behaviour in relation to control devices, especially bait stations and baits. The review is based on searches of computer databases and information from key researchers on: taste preferences, meal size, neophobia, feeding behaviour, movements, home ranges and territoriality, bait shyness, aversion, resistance, odours, and colour preference. Other aspects of rodent behaviour, including responses to repellents, sounds and traps, are also briefly summarised |

review of the literature on seed fate in whitebark pine and the life history traits of Clark's nutcracker and pine squirrels / Whitebark pine is a critical component of subalpine ecosystems in western North America, where it contributes to biodiversity and ecosystem function and in some communities is considered a keystone species. Whitebark pine is undergoing rangewide population declines attributed to the combined effects of mountain pine beetle, white pine blister rust, and fire suppression. The restoration and maintenance of whitebark pine populations require an understanding of all aspects of seed fate. In this paper, we review the literature on seed dispersal in whitebark pine. Clark's nutcracker, pine squirrels, and scatter-hoarding rodents are all known to influence whitebark pine seed fate and ultimately affect the ability of whitebark pine populations to regenerate. We also provide a general overview of the natural histories of the most influential species involved with whitebark pine seed fate: Clark's nutcracker and the pine squirrel |

Rodent bait preferences in non-target birds Rodent control operations are being done, using new bait formulations, in native forest remnant areas of the Pureora Conservation Park. To assess potential risk to non-target species, feeding trials were carried out on North Island robins (Petroica australis longipes), which are common in the treated areas. Three formulations of a toxin-free rice-based gel bait, developed by Feral Control, were compared with a standard toxin-free, cinnamon-lured cereal bait. The robins showed little interest in either bait, with only three out of 40 pecking at the gel and only one at the cereal pellets, and the slight amount ingested would have been well below that for a lethal dose if it had contained toxin. It was concluded that rodent control using warfarin-laced baits of the standard cereal formulation or the aniseed-lured gel formulation presented very low risk to non-target species, although trials to determine risks of long-term exposure to these baits was recommended |

Seed bank dynamics of selected vegetation types in Maputaland, South Africa Results showed that the forest/grassland ecotone and grassland vegetation types produced the largest soil seed bank in terms of seed densities and the Licuati forest and thicket vegetation the smallest, in fact the latter had almost no persistent seed bank. Within each vegetation type the seed bank size showed clear seasonal variation. Seed distribution was concentrated in the upper soil layers. The flotation and physical separation method produced much larger seed numbers than the seedling emergence method. Generally, there is no or very little correspondence between the number of species recorded in the seed bank and that of the standing vegetation. It was found that the seed bank of the different vegetation types, if present, was a fairly poor predictor of the species composition of the existing vegetation, especially in terms of woody species |

Site preparation of abandoned fields and early establishment of naturally and direct-seeded birch in Sweden / Seedling survival and establishment without preparation, and with rotary cultivation, were close to nil, while the other soil preparation methods generally were more effective. Best seedling survival and establishment were obtained on seedbeds created by removing topsoil or by transposing it by deep ploughing or inversion. These seedbeds also suppressed competing vegetation, compared to seedbeds with topsoil at the surface. Seedling establishment after removal of topsoil, amounting to 8% of sown germinable seed, was outstanding on sandy soil, but much poorer on silty soil. The tallest dominant seedlings were found on seedbeds with topsoil within the soil profile. Application of peat litter to the seedbed promoted seedling establishment |

Use of herbicidal gels on woody weeds / This report covers the final group of a series of trials investigating the use of herbicidal gels to selectively control a range of environmental weeds growing in Department of Conservation (DOC) reserves in the North and South Islands of New Zealand and Stewart Island. These trials were set up in early 2000 and assessed at one and two years after treatment. We have investigated a range of application systems to control juvenile and mature trees of (1) Darwin's barberry (Berberis darwinii) in Stewart Island, (2) cotoneaster (Cotoneaster simonsii) in Southland, and (3) grey willow (Salix cinerea) in wetlands near Lake Taupo. Control methods included: (1) applying gel from a bottle on to cut stems; (2) cutting wedges in tree trunks with a pruning saw or axe and applying gel to the wedge; and (3) drilling holes at intervals around the trunk into which herbicide is injected. In a pilot-scale residue study, involving cut-stem and whole-tree treatments of glyphosate or picloram gel to grey willow growing in static water at the Whangamarino wetlands, traces of residues were detected around treated trees and saplings at two to nine weeks after treatment, but levels of residues decreased to nil by 24 weeks after treatment, except in one instance. This information has been used to develop guidelines for DOC staff on how to use herbicidal gel technologies effectively in the field; these are given in the appendix |

vegetation potential of natural rangelands in the mid-Fish River valley, Eastern Cape, South Africa towards a sustainable and acceptable management system / Desertification is the diminution or destruction of the biological potential of land, and can lead ultimately to desert-like conditions. The vegetation of southern Africa is claimed to have altered over the past 100 years and much of the change is attributed to pastoral practice. In recent years however there has been much debate around the issue of the deterioration and loss of productivity of the natural rangelands, specifically those under communal management. It is one thing to claim that the vegetation has changed but quite another to produce data and analyses to show this unequivocally. Furthermore it is generally difficult to determine the nature and extent of change in natural ecosystems, as one does not know what the optimal base-line conditions should be. For this reason emphasis has been placed on developing models of potential or expected vegetation. By comparing a model of potential or expected vegetation with that of the contemporary vegetation, areas that deviate from expectation can be identified, in so doing providing evidence of the direction of change in the rangelands under various management treatments. The objective of this study was to determine shifts in the vegetation under different land-use treatments, by developing a technique to predict the potential vegetation of an area. In order to explore the nature and extent of degradation at the landscape scale a study site was selected where a range of land-use and rangeland management practices could be studied in parallel. The mid-Fish River valley consists of three markedly different units of land management, namely commercial rangelands, communal rangelands and nature conservation areas. The vegetation within the mid-Fish River valley falls within the Thicket biome and consists of three main vegetation types namely, Short Succulent Thicket, Medium Succulent Thicket and Mesic Bushclump Savanna. The creation of this potential vegetation model was dependent on the direct gradient analysis approach of relating the community patterns with environmental variables. To achieve this, floristic information was collected at sites along a topographical-moisture gradient. A Canonical Correspondence Analysis (CCA) between the environmental variables and the plant communities produced a classification from which the conditions normally associated with the major plant communities were predicted. When projected as a digital map, the qualifying sites provided a testable hypothesis of the potential vegetation. The results of this study showed a definite grazing gradient, which reflects a change from a more mesic environment towards a more arid environment with an increase in utilisation pressure. The predictive vegetation model proved to be useful for predicting the occurrence of the valley thicket communities within the Eastern Cape |

Volume yield to mid-rotation in pure and mixed sown stands of Pinus sylvestris and Picea abies in Sweden / Volume yield to mid-rotation in pure and mixed sown stands of Scots pine and Norway spruce was investigated in an experiment in central Sweden. The 43-year-old stands were situated on a 7-ha site and were treated and inventoried at the time of establishment, then at intervals in the life of the stands, to give results at half-rotation age. The dynamics of the mixed stands implied a favourable ecological mixed-stand effect on the height growth of spruce in early development and before crown closure. Even at this stage, pines were taller than spruces, but height was not influenced by admixture with spruce. Pines continued to grow faster than spruces in both height and diameter, resulting in dense mixed stands with dominant pines and co-dominant or suppressed spruces. Diameter of pines was increased by weaker competition for nutrients, while weaker competition for light led to a lower height of dominant pines in mixed stands than in pure pine stands. The results indicate a slight etiolation effect of competition for light in the crown layer. Total volume yield was higher in mixed stands than the mean yield in pure stands of pine and spruce, mainly owing to the dominance of pine in mixed stands. However, it was lower in mixed stands than in pure pine stands. The growth dynamics to the present time indicates that, after a slow start, volume growth of spruce increases remarkably in pure stands and increases slightly in mixed stands. while volume growth of pine began early and is culminating |

Willow resilience on Yellowstone's Northern Elk Winter Range a function of environmental gradients / Willow, a deciduous, woody shrub, is a characteristic and often dominant riparian species that has been unable to successfully regenerate throughout much of its western range, and Yellowstone National Park is no exception. The primary objective of this study was to understand growth and maintenance of established willow stands as a community and as individual species following winter browse. These were based on the premises that (1) different levels of herbivory produce varying levels of compensatory growth, (2) different channel types provide diverse hydrologic conditions for vegetation establishment and maintenance, (3) riparian biodiversity is a function of fluvial dynamics and is increased by the degree of hydrologic connectivity of the system, and (4) the possibility of willow species being either generalist (showing water source shifts) or specialist (availability doesn't influence water source). Site selection and design, and sampling scheme were designed to evaluate biophysical gradients both within and between sites over time. Gradients of biophysical parameters were quantified throughout the growing season. Regressions were used to identify relationships among physical and biological parameters or characteristics. Vegetative communities were compared using Sorenson's similarity index. Ecosystem functions that influence willow presence on the Northern Range include establishment, browse pressure, and maintenance and resilience or their ability to recover. Establishment of willow was a result of availability of their preferred water source while winter decline was a function of location and herbivore preferential selection. Maintenance and resilience were dominated by soil water use in the early season and groundwater use later in the season but with distinct variations between hydrologic systems. Nutrient availability and hyporheic connectivity, essential to dispersing those nutrients among the plant communities, also may influence growth and resilience of willow plants. However, excess or even "acceptable" levels of only one of the physical factors was not enough alone to control dominant plant growth and response to herbivory |

The stand age range was 34-89 years. On the most productive sites trees attain a dominant height of 27 m at age 60 years. Tree height increment is still continuing at age 90 years. The productivity of larch varies widely, depending on site quality. During a 100-year rotation, the total volume yield of larch on medium sites was calculated at 500 m3 ha-1, and at 1000 m3 ha-1 on the most productive sites (both including bark). On the most productive sites, stem volume yield of larch exceeded that of indigenous conifers by 10-25 per cent (excluding bark). On poor, dry, flat or waterlogged sites the yield of larch was inferior to that of indigenous conifers. On high-altitude sites, surprisingly high yields were observed |
