St. Tammany Parish, Louisiana, has experienced tremendous population growth in the past 20 years resulting in the loss of both agricultural and timber lands to development. This study uses logistic regression to predict the probability of development for forested land in St. Tammany Parish. The software used includes ArcInfo, Grid, ArcView GIS, Wessex First St., and SAS. Geographic data sets include satellite imagery from 1981 and 1993, demographic data from the U.S. Census Bureau, population growth estimates from the St. Tammany Parish Government, and road coverages from Wessex First St.
