Abstract: LTAs charactarize landscapes of 1 to 10 square miles and depict broad patterns of geology, geomorphology, soils and vegetation. They were created by nesting existing R10 soil mapping and the NRCS STATSGO general soil map within the Ecological Subsections. All of the LTAs were scrutinized and refined by a team of Tongass Ecologists and Soil Scientists. The Ecological Subsection lines in this feature class are different than the Ecosubsections feature class. They were refined as part of the LTA mapping effort.All descriptions are in an accompanying pdf called "Landtype Associations of the Tongass National Forest"
Purpose: The Land Type Assocation component withing the Alaska TEUI hierarchy. This provides broad-scale ecological information for the Tongass National Forest and small portions of assocaited private lands.
