<br />INTRODUCTION <br />The CF&I Steel Corporation operates the Allen Mine located <br />35 miles west of Trinidad, Colorado. <br />Allen Mine is an underground coal mine. Disturbance to the <br />land results from storage buildings, construction activities, roads, <br />power lines, railroads, waste disposal, and the mining entrance. <br />The A11en Mine permit area encompasses three vegetation types: <br />L <br />~` <br />the Ponderosa pine-Douglas fir-oak (Pious ponderosa-Pseudotsuga <br />menziesii- uercus gambelii), Ponderosa pine-oak (Pious ponderosa- <br />uercus gambelii), and Willow Carr (Salix exigua) types. Affected <br />areas and reference areas of each vegetation type were inventoried <br />for vegetation cover and production by major species and species <br />categories. The term affected area refers to the actual vegetation <br />type sampled. Density of trees, shrubs and saplings in each type was <br />also obtained. The results of the inventory were used to identify <br />dominant species in each type. <br />1 <br />
