Summary

The vegetation map will be used by TNC for three primary purposes: Track changes that may occur to vegetation and associated wildlife habitats over time. To better understand the distribution of rare vegetation types not adequately mapped or described in existing classification systems. To contribute to building a better Statewide vegetation map.

Description

Aerial Information Systems, Inc. (AIS) was contracted by The Nature Conservancy to create a vegetation map covering approximately 11000 acres (~17 square miles) known as the Gabilan Ranch south of the town of San Juan Bautista. The goal of the project is to create a baseline vegetation map depicting existing conditions within the study area.
