1 Landcover Classification for Conservation Planning

2 Reason for Improved Landcover Classification: Habitat Modeling when data is not available for RSFs Identifying Ecological Communities Many Problems with Existing Classifications: One size fits all attitude Extent of area covered Disconnect between botanical and remote sensing classifications Lack of consistent standards End result: 1,000s of project specific landcover classifications They are usually incompatible with each other Existing classifications are manipulated or less than desired classifications are used

3 Montana GAP Landcover

4 Montana & Wyoming GAP

5 Wyoming Classification 8028 acres 80% lodgepole pine 20% subalpine meadow

6 Methods to Account for Differences Crosswalk Independent rating

7 Conservation Needs of a Landcover Classification (emphasis on wildlife modeling) Information and Scale Must Match the Needs of the Species Structure Adaptable across different scales Minimize source of errors Compatibility Easy to produce Cost effective
