Layer: GFDL Low Modeled 2070-2099 Importance Values (ID: 38)

Parent Layer: Eastern Hemlock

Name: GFDL Low Modeled 2070-2099 Importance Values

Display Field: Ecoregion

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: This dataset contains modeled suitable habitat information used by the Climate Change Atlas, which documents the current and possible future distribution of 134 tree species in the Eastern United States and gives detailed information on environmental characteristics defining these distributions. For each species, importance values (IV) were calculated to represent the relative abundance among inventory plots, which are then averaged among all plots within each 20 x 20 km modeling grid. Values of the actual, modeled current, and potential future IVs are provided. Current and future IVs were predicted using Random Forest, an ensemble of regression trees, to model actual mean IVs among 20 x 20 km grids and 38 environmental variables.
