Tree-dwelling mammals are potentially highly vulnerable to discontinuities in habitat created by roads. We used population modeling to assess the viability of a metapopulation of Australia’s largest gliding marsupial, the greater glider (Petauroides volans), occurring in forest remnants in the fastesturbanizing region of Australia, where habitat is dissected by major roads. Crossing structures ...

Forest road pavement needs an evaluation methodology based on a comprehensive assessment of conditions. This research was conducted to evaluate the performance method for rating surface condition forest roads and eventually adapt situation prevailing in network. The selected as basis this experiment index (PCI) developed by U.S. Army Corps Engineers urban roads. In addition, unpaved (URCI) that...

Interest in portable bridge systems has increased in the U.S. due to heightened awareness of the need to reduce environmental impacts and costs associated with road stream crossings. However, design criteria are needed for portable bridges to insure that they are safe and cost effective. This paper discusses different portable bridge categories and their general design criteria. Specific emphas...

Retention forestry, including the retention of woodland key habitats (WKH) at the forest stand scale, has become an essential management practice in boreal forests. Here, we investigate the spatial distribution of 9470 habitat patches, mapped according to the Complementary Habitat Inventory method (CHI habitats), as potential WKHs in 10 sample areas in Norway. We ask whether there are parts of ...
