Mitigating Highway Impacts on Ecosystems EVALUATION OF A RAPID ASSESSMENT PROTOCOL TO ASSESS ROAD-STREAM CROSSINGS FOR AQUATIC ORGANISM PASSAGE
The River and Stream Continuity Partnership has developed assessment protocols for evaluating the barrier effects of road-stream crossings. In addition to these protocols, the University of Massachusetts Amherst created an online database and an algorithm for scoring crossing structures according to the degree of obstruction they pose to aquatic organisms. In 2008, The Nature Conservancy and Un...
متن کاملWildlife Crossings – Location and Design MULTI-SCALE HABITAT-RESISTANCE MODELS FOR PREDICTING ROAD MORTALITY “HOTSPOTS” FOR REPTILES AND AMPHIBIANS
As road networks and traffic volumes increase, road-effects on animal populations are becoming more prevalent. Our goal was to identify herpetofaunal crossing hotspots on roads and to use this information to prioritize deployment of mitigation efforts. Our focus was New York State where in a collaborative effort between ecologists and the New York State Department of Transportation we synthesiz...
متن کاملThe Importance of Riparian Vegetation to Stream Ecosystems
Ab$tract.--Riparian vegetation is very important in determining the structure and function of stream ecosystems. Most aquatic organisms, both invertebrates and fish, are directly or indirectly dependent on inputs of terrestrial detri tus to the stream for their food. Natural changes in riparian vegetation and the biotic processing of detritus, as well as other factors, determine the kinds and a...
متن کاملLandscape Planning for Conservation, Based on the InVEST Model of Habitat Quality and Ecological Impact Assessment of Road Network in Chaharmahal & Bakhtiari Province
One of the primary goals of conservation portfolio selection approaches is to create a functional landscape or network of sites that can support all elements of biodiversity and minimize the environmental risk to critical habitats and species. As human activities, especially roads network development, can be regarded as one of the most important risk elements for the valuable habitats and s...

Development of roads through protected areas and ecological sensitive regions can have catastrophic effects on wildlife. In Iran, road construction in sensitive habitats and protected areas has been expanding during the past decades. This study focuses on the ecological impacts of Isfahan’s west ringway, which passes through Ghamishloo wildlife refuge, I.U.C.N category IV, in Isfahan Province. ...
