 High Altitude Weeds with
 Big Attitudes
 By: Marlin Jenson, GMUG National Forests, Mark Tucker, San Juan National
 Forest and Tom McClure, Rocky Mountain Region Invasive Species Coordinator

 Noxious weeds have not affected the higher elevations of
 Colorado nearly to the extent that has occurred at lower el-
 evations. When we think of “high elevation” in Colorado for-
 ests, we generally are talking about those areas in sub-alpine
 and alpine habitat types-areas above 9,500 -10,000 feet.

 While all National Forests in Colorado contain a consider-
 able amount of area with high altitude habitats, this article
 will highlight weed issues in the San Juan National Forest
 and the Grand Mesa, Uncompahgre, and Gunnison (GMUG)
 National Forests. These Forests contain some of the wildest,
 most diverse and most scenic land in Colorado.

 Subalpine areas within these Forests have long been infest-
 ed with a variety of state-listed non-native species. The most
 common is Canada thistle (Cirsium arvense). It has been
 established for 50-75 years in this habitat type and occurs
 commonly around riparian areas in semi-moist soils. It is
 also very common on beaver dams and around other ponds
 in the subalpine zone. Although in most areas it is not a
 dominant part of the plant community, it quickly expands with
 ground disturbance of any kind.

 Another species common to higher elevations, including the
 subalpine zone, is ox-eye daisy (Leucanthemum vulgare).                      High Alpine

 Rock cinquefoil (Potentilla rupincola), an imperiled member of
 the rose family that has a global and state conservation rank
 of G2/S2 and is classified as a sensitive species by the USFS.
 A Colorado endemic, rock cinquefoil is restricted to Larimer,
 Park, Boulder and Clear Creek counties. It is found at middle
 elevations in poor, dry soils composed of granite and schist.
 Numbers are limited by slow seed reproduction; exotic spe-
 cies invasions are, therefore, a high threat. Rock cinquefoil
 is a low growing forb with pinnately compound, bright green
 leaves and vivid yellow flowers. Don’t confuse this imperiled
