Modeling Habitat Fragmentation in Relation to Road Systems: A Tool for Transportation Planning in California
| 项目名称： | Modeling Habitat Fragmentation in Relation to Road Systems: A Tool for Transportation Planning in California |
| 摘要： | Transportation planners increasingly need effective metrics of biological impact to assist in mitigation assessment. We propose to develop Effective Mesh Size, Effective Mesh Density and Landscape Division as implementable metrics of habitat fragmentation for use in transportation planning. These metrics are developed as GIS layers, which can be used in planning and assessment of biological impact, and can be re-calculated for new roads in a scenario modeling environment. These innovative and biologically meaningful measures of landscape fragmentation will be applied to the mapped ranges of 10 key animal species. The expert in Effective Mesh Size, Dr. Jochen Jaeger, will be a Research Ecologist at UC Davis Road Ecology Center for two months to develop the models, once the UC Davis team has compiled the necessary data into the proper formats. Aspects of this methodology have already been adopted by several states in Germany and in Switzerland, and it is currently under assessment in Canada. Final products from the proposed effort will include three new GIS layers, peer-reviewed papers, and a technical report describing their use, that can be adopted directly for transportation planning in California, and that will serve as a model and metric for transportation planners throughout the world. |
