Abstract In many agricultural landscapes, significant biodiversity gains can be made by improving the ecological condition of degraded remnants of semi‐natural habitat. Recent emphasis has been on the level of management intervention required to initiate vegetation recovery in small forest remnants, but no comparable emphasis has been placed on benefits for invertebrate communities. In the Waikato region, New Zealand, we tested the effects of livestock exclusion, mammalian pest control, and… 

Resilience of New Zealand indigenous forest fragments to impacts of livestock and pest mammals

A number of factors have combined to diminish ecosystem integrity in New Zealand indigenous lowland forest fragments surrounded by intensively grazed pasture. Livestock grazing, mammalian pests,

Effects of forest fragment management on vegetation condition and maintenance of canopy composition in a New Zealand pastoral landscape

Neither treatment led to the restoration of indigenous species richness to reference forest levels, nor allowed densities of juveniles of shade-tolerant canopy species to establish to levels commensurate with replacement of existing canopy trees.

Experimental evidence that even minor livestock trampling has severe effects on land snail communities in forest remnants

Summary Land-use intensification is increasing dramatically in production systems world-wide. Livestock production is an important component of production land use, and increases in livestock

Woody plant richness does not influence invertebrate community reassembly trajectories in a tree diversity experiment.

It is shown that woody plant richness did not have direct positive effects on the diversity and community reassembly trajectories of higher trophic levels in the authors' woodland system, which suggests that even low-diversity restoration or carbon sequestration plantings can potentially lead to faunal reassembly outcomes that are comparable to more complex re-planting designs.

Agricultural Intensification Exacerbates Spillover Effects on Soil Biogeochemistry in Adjacent Forest Remnants

Test, for the first time, whether the degree of spillover from farmland into adjacent natural habitats scales in magnitude with increasing land-use intensity, which has important implications for the viability of land-sparing as a strategy for balancing landscape-level conservation and production goals in agricultural landscapes.

A review of biodiversity outcomes from possum-focused pest control in New Zealand

It is demonstrated that both ground and aerial control of this invasive pest in New Zealand has provided substantial collateral benefits for native biota, and a standardised set of biodiversity indicators from a range of taxonomic and functional groupings is needed to strengthen the evidence base for the impacts of invasive pests on native biOTA.

The importance of integrating landscape ecology in habitat models: isolation-driven occurrence of north island robins in a fragmented landscape

Although the role of habitat fragmentation in species declines is well recognised, the effect of habitat quality on species distributions is often studied using presence–absence models that ignore

Effect of grazing on ship rat density in forest fragments of lowland Waikato, New Zealand

An uncalibrated, rapid (one-night) index of ship rat density, using baited tracking tunnels set in a 50 × 50 m grid, showed a promising relationship with the number of rats killed per hectare over the first six nights, up to tracking index values of c.




The results show that the introduction of these mammals to New Zealand has caused far-ranging effects at both the community and ecosystem levels of resolution, with particularly adverse effects for indigenous plant com- munities and populations of most groups of litter-dwelling mesofauna and macrofauna.


Data indicate that spatial configuration is important to mitigate extinction risks when habitat availability in a landscape is low, whereas no effect will be observed when overall area of habitat is high.

Effects of stock grazing on the ground invertebrate fauna of woodland remnants

Habitat fragmentation can leave formerly widespread habitat types represented by only small habitat 'islands', and the conservation of these remnants is frequently compromised by ongoing disturbance.

The effects of habitat fragmentation and livestock grazing on animal communities in remnants of gimlet Eucalyptus salubris woodland in the Western Australian wheatbelt. I. Arthropods

Habitat disturbance was the major influence on the arthropod communities, with remnant biogeographic factors consistently explaining low variations in the abundance or diversity of the fauna.

Long-term impacts of grazing on indigenous forest remnants on North Island hill country, New Zealand

Small isolated patches of native forest surrounded by extensive pastoral grasslands, characteristic of many New Zealand rural landscapes, represent an important reservoir of lowland biodiversity.

Effects of livestock grazing on benthic invertebrates from a native grassland ecosystem

SUMMARY 1. The effects of cattle grazing on stream bank stability, biomass of riparian vegetation, instream vegetation cover, biomass of coarse particulate organic matter (CPOM) and epilithon and

Moose, trees, and ground-living invertebrates : indirect interactions in Swedish pine forests

It is suggested that by affecting the density and composition of tree species, moose indirectly influenced the structure of invertebrate communities and affected the invertebrates in these two Swedish pine forests.

Two points of concern for pest managers are demonstrated: first, indirect effects of control operations do have the potential to reduce the planned-for benefit, and secondly, thresholds in the strength of control employed can potentially occur, across which indirect effects switch from being of Conservation benefit to being of conservation concern.

Grazing in remnant woodland vegetation: changes in species composition and life form groups

Changes in floristics in a large group of remnants of native woodland left after agricultural clearing in southwestern Australia indicate that the significance of the relation- ship between grazing effects and DCA floristic axes was greater than edaphic characteristics that normally influenceFloristic patterns.
