G. Vegetation Types <br />Predominantly mature lodge pole pine, relatively closed canopy. At lower elevations, mixed - conifer <br />forests containing lodge pole pine, ponderosa pine, and Douglas -fir. Upper elevations consist of forests <br />transitioning to Engelmann spruce and subalpine fir. Pockets of aspen exist throughout forested areas <br />and in minor drainage -ways. Limber pine on some ridgelines. <br />Non - forested openings are primarily grass, grass -forb complexes, mountain mahogany, bitterbrush, <br />sagebrush, and other upland shrubs. Major drainages with riparian areas are dominated by graminoids <br />and willows, with alders, Rocky Mtn. maple, and other common riparian vegetation. Steep rocky south - <br />or west- facing hillsidestcanyons of lower elevations with open junipers, ponderosa pine, shrubs and <br />bunchgrasses; steep rocky north- or east- facing hillsides /canyons with bunchgrasses, shrubs, and <br />mixed - conifer forests dominated by Douglas -fir. <br />H. Dominant Soils <br />There are 56 soil units inside the High Park fire perimeter. Dominant soils inside the fire perimeter are <br />divided into three map units which comprise 13% to 25% of the area. These map units are: <br />• Wetmore -Boyle -Rock outcrop complex, 5 to 60 percent slopes, <br />• Ha ploborol Is- Rock outcrop complex, steep, and <br />• Redfeather sandy loam, 5 to 50 percent slopes. <br />These 3 units represent a total of 52% of the burned area. The Haploborolls -Rock outcrop complex is <br />mostly in moderate to low burn severity areas and Redfeather sandy loam units are located mostly in <br />moderate soil burn severity areas. The Wetmore -Boyle -Rock outcrop complex is the dominant soil unit <br />inside high burn severity areas. <br />Rock fragments are abundant across the High Park Fire area. The three most common soil map units <br />generally have between 10% and 60% by volume rock fragments in the surface horizons and between <br />35% and 80% fragments in the underlying subsoil. Surface textures are mostly sandy loam throughout <br />the fire area. Rock outcrops are common throughout the burned area, especially on steep slopes with <br />gradients greater than 60 %. <br />I. Geologic Types <br />There are six main geologic formations in the burned area: two igneous, two metamorphic, and two <br />sedimentary. The igneous formation of granitic rock material covers 19 percent of the area. The <br />metamorphic formations are biotitic and felsic gneiss with schist, and cover approximately 79% of the <br />area. The sedimentary formations are sandstones and limestones. The sedimentary formations cover <br />approximately 1 % of the burned area. Large granite inclusions occur in the south - central area of the <br />burn. Metamorphic rocks (biotitic gneiss and felsic gneiss) occur as a continuous unit inside the <br />perimeter with small inclusions of felsic gneiss formation. <br />J.
