Legacy Land Trust Conservation Values (GIS) Model

  • Client: Legacy Land Trust, Larimer, Jackson & Weld Counties, Colorado
  • Date: Sep 2008 to Feb 2009
  • Info: Blue Mountain was contracted by Legacy Land Trust to develop a Conservation Values Model. This conservation values model was developed in a Geographic Information System (GIS) database to identify places within Larimer, Jackson and Weld counties where conservation values are represented on the landscape.

Conservation values were broken into ecological, agricultural and scenic categories. In order to incorporate these values into the GIS project, available data layers were researched, compiled, weighted, analyzed and filtered. The ecological category was comprised of the Colorado Division of Wildlife Riparian Habitat Map, the Colorado Partners Map and Colorado Natural Heritage Program Potential Conservation Areas Map.

Agricultural values were obtained from USGS SSURGO database and included prime soils and soils of statewide significance. Scenic values included scenic byways and polygons designated by Legacy Land Trust. Preliminary output maps were filtered with COMap to identify private lands where Legacy Land Trust can implement projects. In a separate modeling process, projected urban growth within the project area was utilized to identify where urban growth will be likely to occur near areas that represent conservation values. The primary modeling output and preliminary data layers are illustrated below.
