Rangeland Fractional Cover


Rangeland fractional cover refers to the percentage of a pixel that is covered in a particular vegetation type found in the arid rangelands of western North America. These fractional rangeland vegetation types vary widely as a function of succession after disturbances like wildfire, and often have profound influences on habitat quality for rangeland-associated species. TerrAdapt:Cascadia currently models fractional cover of 4 rangeland vegetation types, including % sagebrush cover, % shrub cover, % perennial grass cover, and % invasive annual grass cover.

In the following sections, we describe the training data and covariates we used to predict rangeland fractional cover, our approach to developing the models, and model validation.
