LF primary focus for this data call is to collect disturbance and treatment polygons from 2015/2016 to be evaluated for use in the next update. If you submit more recent or older data, LF will archive the data for evaluation and potential use in future mapping updates or comprehensive remaps. Refer to Disturbance Data Processing to learn how LF evaluates and processes polygon data.

To submit your data, please follow steps 1-5.
