Hazlett, Michael H. Schiebout, and Paulette L. Ford Hazlett, Donald L.; Schiebout, Michael H.; and Ford, Paulette L. 2009. Vascular plants and a brief history of the Kiowa and Rita Blanca National Grasslands. Gen. Tech. Rep. RMRS- GTR-233. Fort Collins, CO: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 44 p. Abstract Administered by the USDA Forest Service, the Kiowa and Rita Blanca National Grasslands occupy 230,000 acres of public land extending from northeastern New Mexico into the panhandles of Oklahoma and Texas. A mosaic of topographic features including canyons, plateaus, rolling grasslands and outcrops supports a diverse flora. Eight hundred twenty six (826) species of vascular plant species representing 81 plant families are known to occur on or near these public lands. This report includes a history of the area; ethnobotanical information; an introductory overview of the area including its climate, geology, vegetation, habitats, fauna, and ecological history; and a plant survey and information about the rare, poisonous, and exotic species from the area. A vascular plant checklist of 816 vascular plant taxa in the appendix includes scientific and common names, habitat types, and general distribution data for each species. This list is based on extensive plant collections and available herbarium collections. Authors Donald L. Hazlett is an ethnobotanist, Director of New World Plants and People consulting, and a research associate at the Denver Botanic Gardens, Denver, CO.

  • Bringing Back Flowering Plants and Pollinators Through Effective Control of Invasive Winter Annual Grasses with Esplanade® Herbicide
    Bringing back flowering plants and pollinators through effective control of invasive winter annual grasses with Esplanade® herbicide Boulder County Open Space Small Grant Report Submitted by: Dr. Arathi Seshadri, Assistant Professor [email protected] Janet Hardin, Research Associate [email protected] Colorado State University December 6, 2018 Campus Contact: Dr. Arathi Seshadri [email protected] Phone: (970) 491-6804 1170 Campus Delivery, 307 University Avenue Colorado State University, Fort Collins, Colorado 80523 Boulder County staff sponsor: Steve Sauer [email protected] 1 EXECUTIVE SUMMARY Invasive species pose one of the largest threats to the biodiversity native to a region, including impacting important pollinator species. Currently the state of Colorado’s list of noxious species includes 105 species, 9 of which are grasses. Cheatgrass, or downy brome, is one of the most problematic exotic grass species in the American West, and the most widespread of the Colorado listed species, occurring in every county in the state. Control of invasive grasses has largely depended on grazing, prescribed burning, or use of herbicides such as imazapic, glyphosate and rimsulfuron. However, control is challenged by the dependence of livestock on forage grass species and the nonselective nature of many herbicides. Indaziflam (Esplanade), an herbicide recently approved for use in controlling invasive annual grasses on rangelands and open spaces, shows promise to eliminate or limit spread of those invasive grasses. As invasive species are controlled and eventually eliminated, it is expected that the areas previously occupied by the invasive species will be amenable for growth of flowering forbs and in turn support pollinators that depend on these flora.

  • Vascular Plant Species of the Comanche National Grassland in United States Department Southeastern Colorado of Agriculture
    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.

    Literature Cited Robert W. Kiger, Editor This is a consolidated list of all works cited in volume 12, whether as selected references, in text, or in nomenclatural contexts. In citations of articles, both here and in the taxonomic treatments, and also in nomenclatural citations, the titles of serials are rendered in the forms recommended in G. D. R. Bridson and E. R. Smith (1991), Bridson (2004), and Bridson and D. W. Brown (http://fmhibd.library.cmu.edu/HIBD-DB/bpho/findrecords.php). When those forms are abbreviated, as most are, cross references to the corresponding full serial titles are interpolated here alphabetically by abbreviated form. In nomenclatural citations (only), book titles are rendered in the abbreviated forms recommended in F. A. Stafleu and R. S. Cowan (1976–1988) and Stafleu et al. (1992–2009). Here, those abbreviated forms are indicated parenthetically following the full citations of the corresponding works, and cross references to the full citations are interpolated in the list alphabetically by abbreviated form. Two or more works published in the same year by the same author or group of coauthors will be distinguished uniquely and consistently throughout all volumes of Flora of North America by lower-case letters (b, c, d, ...) suffixed to the date for the second and subsequent works in the set. The suffixes are assigned in order of editorial encounter and do not reflect chronological sequence of publication. The first work by any particular author or group from any given year carries the implicit date suffix “a”; thus, the sequence of explicit suffixes begins with “b”.
