  "description" : "Historical Mean Fire Return interval quantifies the average period between fires under the presumed historical fire regime. It is intended to describe one component of historical fire regime characteristics in the context of the broader historical time period represented by the LANDFIRE Biophysical Settings (BpS) layer and BpS Model documentation. Data are driven by LANDFIRE Biophysical Settings--vegetative systems that may have existed on the landscape prior to European Settlement. Fire frequency estimates are based on these historical vegetation systems and may not fully reflect fire needs of current vegetation systems.\n\nFor more information, and to download LANDFIRE data, please visit:\n•\tThe LANDFIRE program website\n•\tThe LANDFIRE Biophysical Settings Models and Descriptions Support website\n•\tThe LANDFIRE Vegetation Modeling website",
