LANDFIRE (LF) Vegetation Disturbance (VDist) products are a composite of Annual Disturbance products for the previous ten years that was used in LF 1.x products.
Disturbances were grouped by disturbance type, or cause, (i.e. fire or mechanical treatment), disturbance severity (Low, Moderate, or High), and time since disturbance. These combinations of type, severity, and time since disturbance were used to inform LF vegetation transitions and to update existing vegetation products (Type, Cover and Height) for disturbances on the landscape. Fire occurrences were assumed to be the most impactful and take precedence, followed by the more recent disturbances taking precedence for a given location.
This product was not developed for LF 2016 Remap and LF 2020 Update.
