Abstract:
Modeled Potential Natural Vegetation Zones of Washington and Oregon
Purpose:
The concept of potential natural vegetation (PNV), the plant community reflecting the environmental capability of a land area, has proven vital to land management over the past 30 years. Rigorous, consistent, validated potential vegetation mapping, however, has remained a persistent need for land management agencies. The development of this dataset represents a new way to model and map PNV to help fulfill those requirements.

Process_Description:
The Potential Vegetation Zone Model uses a set of algorithms to define the upper and lower elevational boundary for each vegetation zone (VZ) within each of 68 ecoregions in the model area (Washington and Oregon). The model algorithms are based on a suite of spatial environmental variables, including elevation, slope, aspect, temperature, precipitation, topographic position, cold air drainage and potential shortwave (i.e., solar) radiation. When the model is run for an ecoregion, the limiting elevation for each VZ boundary is generated and stored in a grid. The last step in the model compares the elevation of each pixel in the landscape to this grid of limiting values and determines which VZ corresponds to each pixel.
