California Fire Perimeters (all)

The fire perimeter and prescribed fire feature service provides a reasonable view of the spatial distribution of past fires. Because of missing perimeters (see Use Limitation) this layer should be used with care in statistical analysis and reporting. Includes separate layers for just large fires (5000+ acres and last 5 years) and by decade (since 1950). The data and service is updated annually with fire perimeters from the previous fire season.
