Latest NewsThe Succession Class (SClass) product 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. These components 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:
Note: SClass is not always created for all extents and/or all versions of LF. See the schedule page to learn more about each version.
