The primary purpose of this dataset is for use in developing a species conservation and monitoring plan for the areas of San Diego, California which burned during the Cedar and Otay fires of 2003.
Linear vegetation transect surveys in San Diego County were conducted by the USGS as part of a post fire monitoring project. The dataset contains spatial and temporal information on species detections. Dataset includes detection records from March 2005 to December 2009. Accuracy of individual data fields have been reviewed and data collection efforts are ongoing.
METHODS: A 50 meter, linear transect, centered on the central pitfall bucket of the drift fence array, is used to characterize the habitat associated with each array. Every half meter along the transect, all plant species at the point are recorded. A total of 100 points are documented along the transect. Each plant species is only reported once per point. A visual survey is also performed to record any plant species which may be in the general vicinity, but which did not occur along the survey transect.

Use restricted to government agencies. Positional accuracy of individual locations is limited by: accuracy of satellite GPS locations, observer error, and possible data entry errors. Although, all reasonable attempts have been made to limit these factors, positional accuracy for any individual point should not necessarily be considered minimal.
