landcover classification for conservation planning

Landcover Classification for Conservation

Planning

Reason for Improved Landcover Classification:Habitat Modeling when data is not available for RSF’s

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:1,000’s of project specific landcover classifications

They are usually incompatible with each other

Existing classifications are “manipulated” or less than desired

classifications are used

Conservation Needs of a Landcover Classification

(emphasis on wildlife modeling)

Information and Scale Must Match the Needs of the SpeciesStructureAdaptable across different scales

Minimize source of errors

Compatibility

Easy to produce

Cost effective
