Wildlife corridors and the mitigation of logging impacts on fauna in wood-production forests in south-eastern Australia: a review
1994
Lindenmayer, D.B. (Australian National Univ., Canberra. Centre for Resource and Environmental Studies)
Investigations of wildlife corridors in Australian forests are limited, however a review of the range of studies indicates that many factors have the potential to influence the use of corridors by wildlife. These include: the biology, ecology and life history of species; habitat suitability and attributes (width, length) of retained strips; the location of sites in the landscapes; the type of logging operations and their intensity and pattern at a landscape scale; the suitability of habitats for fauna in the areas surrounding retained strips; the value for fauna of reserves connected by corridors. This diverse array of factors means that it is important to identify explicitly both the species targeted for conservation and the principal objectives of establishing a network of wildlife corridors within a given area of wood-production forest. Such an analysis may reveal that, within the constraints that typically apply in timber-production forests, it may not be possible to design corridor systems that conserve all of those species that are vulnerable to the effects of timber harvesting. As a result of limited data, it is presently not possible to assess the adequacy of most prescriptions for wildlife corridors. Consequently, more investigations of wildlife corridors are required to provide data to guide their design. In the meantime, a conservative approach to forest management is recommended.
