Introduction The Raton Creek Mine permit area is located in Starkville, Los Animas County, Colorado, approximately three miles south of Trinidad. The site is in the foothills of the Rocky Mountains and consists of hilly terrain cut by deep gulches. The elevation of the site ranges from 6,340 to 7,200 feet. A vegetation survey was conducted on the permit area from 12-19 July 1982. Two vegetation types were identifed on the permit area during the survey. The most abundant vegetation type is pinyon-juniper, covering approximately 95 percent of the permit area. This type is found on all aspects of the hills of the permit area. The understory varies from sparse grasses to dense brush. The other vegetation type, refered to as bottomland, is found at the bottom of the hills on the western edge of the permit area and covers approximately 5 percent. This vegetation type appears to have been a grassland originally Most of this type which was on the permit area has been disturbed in the past. The area which was sampled is located just west of the permit area boundary at the site of a former residential area of Starkville. Although buildings have long since disappeared, the disturbance has resulted in a flora which is typical of disturbed areas. A list of plant .species observed on the Raton Creek Mine permit area is found in Table 1. Several species could be identified only to genus because of a lack of flowers or fruits needed for species identification. Methods permit Map No. 8 is a~l" = 400' scale map of the study area, showing vegetation types and sample locations within the pinyon-juniper vegetation type. permit Map No. 9 is a 1" = 200' scale map showing sample locations within the bottomland vegetation type. permit Map No, 1o is an aerial photograph of the permit area, showing the approximate boundaries of the permit area. The photograph is distorted and therefore not appropriate for use in indicating sample locations. 219 Revised 5/93
