Summary
Three .csv files contain occurrence points (longitude and latitude) for three woody vegetation communities found in Texas, Oklahoma and New Mexico. Points were extracted from publicly available LANDFIRE Environmental Site Potential 30 m raster downgraded to 1 km using a majority classification algorithm. The three communities are an oak type (dominated by Quercus stellata and Q. marilandica), a mesquite type (dominated by Prosopis glandulosa and P. velutina), and a pinyon-juniper type (dominated by Pinus edulis and Juniperus osteosperma). The 21 rasters contain environmental suitability scores for each of the three communities, generated with MAXENT freeware using historic and projected climate and fire probability data for three [...]

The 21 rasters contain environmental suitability scores for each of the three communities, generated with MAXENT freeware using historic and projected climate and fire probability data for three periods: 1900-1929, 2040-2069, and 2070-2099.

Purpose
Climate and fire are global drivers of plant species distributions, and variations in climate and fire frequencies favor different species assemblages, or communities. The primary objective of the study was to develop simple models to relate fire probability and climate conditions to the historic distribution of important woody communities in Oklahoma, Texas, and New Mexico, and project where on the landscape these conditions might occur in the future. The inclusion of fire probability adds an important driver of vegetation distribution to climate envelope modeling.
