Presented at USEPA Remote Sensing Landscape Characterization Workshop, Chicago, IL, November 01 - 03, 2005.
Impact/Purpose:
There are four basic objectives of the project:
Demonstrate the application of a comparative landscape assessment in analyzing the vulnerability of surface and coastal water conditions to declines based on landscape conditions (as estimated by landscape indicators as demonstrated in the mid-Atlantic landscape atlas) in western environments;
Develop and apply landscape assessment approaches relative to specific issues, including an ability to prioritize the vulnerability of areas relative to the Clean Water Act 303(d) designations; Quantify relationships between landscape conditions (as measured by landscape indicators) and surface and coastal waters in the west to reduce the uncertainty in comparative landscape assessments, and issue-specific, landscape assessments (e.g., Total Maximum Daily Load (TMDLs);
Complete a west-wide, comparative landscape assessment relative to surface and coastal water vulnerability;
Transfer landscape assessment technologies to Regional Offices so that they can conduct landscape assessments at many scales.
Description:
Structural physical habitat attributes include indices of stream size, channel gradient, substrate size, habitat complexity and cover, riparian vegetation cover and structure, anthropogenic disturbances and channel-riparian interaction.
