Forest Reference Conditions
Researchers will reconstruct presettlement (circa 1880) forest reference conditions by studying live and dead trees within a 2000 ha unlogged forest in the General Creek watershed. Based on the age distribution of these trees, they will analyze presettlement fire regimes in relation to topography. They will use the Forest Vegetation Simulator to characterize and depict presettlement forest conditions in different groups, and then they will use the Fuel Characteristic Classification System (FCCS) to characterize surface and canopy fuels in each group and across the landscape using a Geographic Information System (GIS). By modeling fire behavior, researchers will calculate how far current conditions have departed from their presettlement reference conditions.
Full Title: Identifying Spatially Explicit Reference Conditions for Forest Landscapes in the Lake Tahoe Basin, USA
Lead Researchers: Alan Taylor, Penn State University; Carl Skinner, USFS Pacific Southwest Research Station; Hugh Safford, USFS Region 5
Plot and stand-level data on site characteristics and presettlement forest structure will be obtained for previous studies led by the principal investigator. Further sampling of uncut forest in the General Creek watershed will be necessary to ensure a full representation of forest conditions and topographic variables.
Timeframe: September 2008 through August 2011 (3 years)
Expected date of final products: August 2011. Progress Report available for download
