Montana Land Cover Mapping

Land Cover mapping for Montana is under the stewardship of the Montana Natural Heritage Program (MTNHP) and is conducted by the University of Montana Spatial Analysis Lab (UM-SAL). Replacement of previous MSDI land cover mapping is ongoing. Currently recommended land cover data, mapping methods and Montana land cover data can be explored and downloaded from the following links:

• MSDI Land Cover homepage
• UM-SAL Land Cover story map
• Montana Land Cover working group theme lead

Ecological Site Reviewer

The Ecological Site Reviewer (ESR) is an ArcGIS online web map application that displays biophysical data such as soils, elevation, slopes, aspect, frost-free days, landscape level ecological units, ecological sites, classified vegetation and background locational data. The ESR can be used for preliminary site evaluation, navigating to locations of interest, assessing key environmental attributes and generating maps.
