The Succession Class (SClass) layer characterizes current vegetation conditions with respect to the vegetation species composition (leaf-form and life-form primarily), cover, and height ranges of the successional states that occur within each Biophysical Settings (BpS) . SClass can also represent uncharacteristic vegetation components, including exotic species, tree plantations, canopy cover, etc. that are not found within the compositional or structural variability of successional states defined for a BpS. Succession classes do not directly quantify fuel characteristics of the current vegetation, but rather represent vegetative states with unique succession or disturbance-related dynamics, such as structural development or fire frequency.
To produce SClass, mapping rules defined by local and regional experts during the original development and subsequent review of each BpS are applied to the relevant current vegetation layers. SClass mapping rules for all natural BpS are available for download in spreadsheet format.
SClass is part of the LF Remap release of Fire Regime products.
The comma separated value (CSV) file used for the raster attribute table is included in the LF product download in database file (DBF) format.
