To know what habitats we have, how much and where: 3. In raw form -can have too much information: automatically classified data can have error, small scale mapping- aerial photography, draw polygons around habitats in gis, map boundaries of habitats with gps. Bailey (1976) = ecoregions of the us: 2. Anderson (1976) = land use/land cover of remotely sensed data (usgs national land. Cowardin et al. (1979) = wetlands (usfws: 4. Comer et al. (2003) = ecological systems of the us (natureserve) Lacustrine: palustrine, subsystems based on the degree or frequency of inundation, classes based on hydrological, substrate, and/or vegetation characteristics. Important classification and mapping considerations: numberof habitat categories, there is loss of information as categories become aggregated. Classification accuracy importantsource of error: age of data some data change more rapidly than others.
