At onetime nonarable land where Dust Bowl storms of the 1930s originated, the Purgatory Watershed is presently home to the Comanche National Grasslands, the Picketwire Canyonlands, and the expansive Piñon Canyon Maneuver Site.

  • Porter's Sagebrush Is Endemic to the Wind River and Powder River Basins in Central Wyoming
    Status of Porter’s Sagebrush (Artemisia porteri) in Wyoming Prepared for the Bureau of Land Management Wyoming State Office And Wyoming Natural Diversity Database, University of Wyoming By Walter Fertig Botanical Consultant 1117 West Grand Canyon Dr. Kanab, UT 84741 25 September 2002 Agreement # K910-A4-0011 Task Order No. TO-09 ABSTRACT Porter's sagebrush is endemic to the Wind River and Powder River basins in central Wyoming. It is found primarily in sparsely vegetated Artemisia pedatifida, A. longifolia, or A. porteri communities on barren clay or ashy badlands, flats, or gullies derived from the Wind River, Wagon Bed, or Frontier formations. This species is currently known from 11 extant occurrences consisting of at least 60 subpopulations covering less than 1250 acres. Individual colonies typically number from 100-1000 individuals and occupy areas of 1-50 acres. Based on surveys in 1999, the current population of Porter's sagebrush is conservatively estimated at 50,000-75,000 plants. Porter's sagebrush is primarily threatened by mineral development (oil, natural gas and uranium) within its limited range and specialized habitat. This species was designated as Sensitive by the BLM in 2001 and occurs primarily on BLM lands in the Buffalo, Casper, and Lander field offices. No populations currently receive formal protection, although the population in the Lysite Badlands is managed under special use regulations in the BLM Lander Resource Area Resource Management Plan. Porter's sagebrush is now known to be more widespread and abundant in Wyoming than previously suspected. Until sufficient habitat is afforded protection or management strategies are developed and implemented for this species in mineral extraction areas, A.

The projects, both conducted by the Colorado Natural Heritage Program, are two distinct projects that are highly integrated with respect to methodology and fieldwork. Both projects utilized the same Natural Heritage methodology that is used throughout the globe, and both searched for and assessed the plants, animals, and plant communities on the Colorado Natural Heritage Program’s list of rare and imperiled elements of biodiversity. Each report prioritizes potential conservation areas based on the relative significance of the biodiversity they support and the urgency for protection of the site. All information explaining Natural Heritage methodology and ranks is repeated in each report, so that each report can stand alone and be used independently of the other. This report, Survey of Critical Biological Resources of Pueblo County, presents all potential conservation areas identified in Pueblo County that support rare and imperiled plants, animals, and significant plant communities, including wetland and riparian areas.

    Vascular Plant Species of the Comanche National Grassland in United States Department Southeastern Colorado of Agriculture Forest Service Donald L. Hazlett Rocky Mountain Research Station General Technical Report RMRS-GTR-130 June 2004 Hazlett, Donald L. 2004. Vascular plant species of the Comanche National Grassland in southeast- ern Colorado. Gen. Tech. Rep. RMRS-GTR-130. Fort Collins, CO: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 36 p. Abstract This checklist has 785 species and 801 taxa (for taxa, the varieties and subspecies are included in the count) in 90 plant families. The most common plant families are the grasses (Poaceae) and the sunflower family (Asteraceae). Of this total, 513 taxa are definitely known to occur on the Comanche National Grassland. The remaining 288 taxa occur in nearby areas of southeastern Colorado and may be discovered on the Comanche National Grassland. The Author Dr. Donald L. Hazlett has worked as an ecologist, botanist, ethnobotanist, and teacher in Latin America and in Colorado. He has specialized in the flora of the eastern plains since 1985. His many years in Latin America prompted him to include Spanish common names in this report, names that are seldom reported in floristic pub- lications. He is also compiling plant folklore stories for Great Plains plants. Since Don is a native of Otero county, this project was of special interest.
