Fire history reconstruction (1482 - 1952), Andrews Experimental Forest and vicinity
Abstract
Fire History - H J Andrews and Vicinity (1482 - 1952) individual fires and fire frequency. Fire history studies by Peter Teensma provide the base information for this layer. Individual fire episodes were manuscripted onto HJA base maps and digitized. Fire episodes were maintained in thirty one separate polygon coverages, until Arc/Info Version 7 provided the region feature class to accomodate overlapping polygons. REGIONPOLY was used to create regions for each fire episode and then the 31 episode regions were combined using UNION. The field "AGE" = 0 means that a fire occured in the polygon. AGE = 1 means that fire was absent
