aPotential vegetation type: Defined as a classification system that integrates a variety of physical and biological components including climate, soil, geology and vegetation. These are are identified by species indicative of similar conditions (Hann and others 1997) White Fir (WF) = Abies concolor Subalpine Fir (SAF) = Abies Lasiocarpa Lodgepole Pine (LPP) = Pinus contorta Engelmann Spruce (ES) = Picea engelmannii Ponderosa Pine (PP) = Pinus ponderosa Quaking Aspen (QA) = Populus tremuloides Douglas-fir (DF) = Pseudotsuga menziesii Pinyon Pine/Utah Juniper (P/J) = Pinus ebulus/Juniperus oesteosperma bCover type: Defined as a plurality of one species or a mixture of two or more species in a particular forest or stand. Cottonwood = Populus spp. Gambel Oak (GO) = Quercus gambelii Big Tooth Maple (M) = Acer grandidentatum
