Sierra Nevada (California, USA) Simulated Fisher Territory Occupancy - Baseline Fire Regime + Moderate Treatment Intensity over 8% Area

This dataset shows simulated fisher territory occupancy for a study area the southern Sierra Nevada range from the Baseline Fire Regime plus Moderate Intensity Treatment over 8% of the treatable area scenario (Scheller and others 2008). Simulations were conducted using the spatially dynamic population model PATCH coupled to the forest succession and disturbance model LANDIS-II. Fisher occupancy is represented as the average number of females per 860 hectare hexagon. Habitat quality was derived from LANDIS-II simulated vegetation dynamics and was used to drive spatially-explicit demographic dynamics in PATCH. The baseline fire regime is derived from the previous 20 years of fire data. The extreme fire regime is a purely hypothetical fire regime intended to produce larger, more severe fires that may occur as a result of climate change. Fuel treatments were applied to either 4 or 8% of the area in the treatable landscape every 5 years and were either low or moderate intensity thinning from below activities.
