ARTICLE X. LANDSCAPING Sec 8-447. Purpose. the City of Del Rio
ARTICLE X. LANDSCAPING Sec 8-447. Purpose. The City of Del Rio experiences frequent droughts and is in a semi-arid climatic zone; therefore, it is the purpose of this article to: (1) Encourage the use of drought resistant plants and landscaping techniques that do not consume large quantities of water. Plants native to Southern Texas/Coahuila Desert are recommended. (2) Establish requirements for the installation and maintenance of landscaping on developed commercial properties in order to improve, protect, and preserve the appearance, character and value of such properties and their surrounding neighborhoods and thereby promote the public health, safety and general welfare of the citizens of Del Rio. More specifically, it is the purpose of this article to: (a) Aid in stabilizing the environment's ecological balance by contributing to the process of air purification, oxygen regeneration, storm water runoff retardation and groundwater recharge; (b) Reduce soil erosion by slowing storm water runoff; (c) Aid in the abatement of noise, glare and heat; (d) Aid in energy conservation; (e) Provide visual buffering and provide contrast and relief from the built-up environment; and (f) Protect and enhance property value and public and private investment and enhance the beautification of the city. (3) Contribute to and enhance the economic welfare of the city and the quality of life of citizens and visitors through the following: a. Promote the image of the southwestern border environment; and b. Create an attractive appearance along city streets -
Maintaining and Improving Habitat for Hummingbirds in Oklahoma and Texas
United States Department of Agriculture Maintaining and Improving Habitat for Hummingbirds in Oklahoma and Texas A Land Manager’s Guide Forest Service National Headquarters Introduction Hummingbirds play an important role in the food web, pollinating a variety of flowering plants, some of which are specifically adapted to pollination by hummingbirds. Some hummingbirds are at risk, like other pollinators, due to habitat loss, changes in the distribution and abundance of nectar plants (which are affected by climate change), the spread of invasive Anna’s Hummingbird Nest plants, and pesticide use. This guide is intended to Courtesy of Steve Berardi Wikimedia Commons help you provide and improve habitat for humming- birds, as well as other pollinators, in Oklahoma and Texas. While hummingbirds, like all birds, have the basic habitat needs of food, water, shelter, and space, this guide is focused on providing food—the plants that provide nectar for hummingbirds. Because climate, geology, and vegetation vary widely in different areas, specific recommenda- tions are presented for each ecoregion in Oklahoma and Texas. (See the Ecoregions in Oklahoma and Texas section, below.) This guide also provides brief descriptions of the species that visit Oklahoma and Texas, as well as some basic information about hummingbird habitat needs. Whether you’re involved in managing public or private lands, large acreages or small areas, you can make them attractive to our native hummingbirds. Even long, narrow pieces of habitat, like utility corridors, field edges, and roadsides, can provide important connections among larger habitat areas. Hummingbird Basics Some of the hummingbird species of Okla- homa and Texas are migratory, generally wintering in Mexico and southern Texas and pushing northward through Nevada and California for summer breeding. -

Any use of trade, firm, or product names is for descriptive purposes only and does not imply endorsement by the U.S. Government. U.S. DEPARTMENT OF THE INTERIOR U.S. GEOLOGICAL SURVEY 1 Denver, Colorado 2 Institute of Arctic and Alpine Research, University of Colorado, Boulder, Colorado INTRODUCTION Packrats, also known as wood rats or trade rats, are herbivorous Sigmodontine rodents belonging to the genus Neotoma (Vaughan, 1990). Twenty-one North American species of packrat are widely distributed from the Northwest Territories of Canada (65˚23' N) to tropical Nicaragua (13˚ N) (Vaughan, 1990). Arid and semi-arid lands of the southwestern United States presently support six different packrat species, which have probably persisted in the region, at least intermittently throughout the past 40,000 years (Vaughan, 1990). Vaughan (1990) summarizes the ecology of modern packrats in North America and the southwestern U.S. All modern packrats demonstrate a habit, unique among rodents, of collecting various items from their surrounding environment. These animals gather a variety of materials including plant debris, rocks, bones, insect parts, and human artifacts, generally from within a limited foraging range (30-50 m) of their dens. Not every packrat species has the same dietary preferences or collecting habits, and some species sample their environments better than others by collecting a greater variety of plant materials from the surrounding landscape. -

Responses of Plant Communities to Grazing in the Southwestern United States Department of Agriculture United States Forest Service
Responses of Plant Communities to Grazing in the Southwestern United States Department of Agriculture United States Forest Service Rocky Mountain Research Station Daniel G. Milchunas General Technical Report RMRS-GTR-169 April 2006 Milchunas, Daniel G. 2006. Responses of plant communities to grazing in the southwestern United States. Gen. Tech. Rep. RMRS-GTR-169. Fort Collins, CO: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 126 p. Abstract Grazing by wild and domestic mammals can have small to large effects on plant communities, depend- ing on characteristics of the particular community and of the type and intensity of grazing. The broad objective of this report was to extensively review literature on the effects of grazing on 25 plant commu- nities of the southwestern U.S. in terms of plant species composition, aboveground primary productiv- ity, and root and soil attributes. Livestock grazing management and grazing systems are assessed, as are effects of small and large native mammals and feral species, when data are available. Emphasis is placed on the evolutionary history of grazing and productivity of the particular communities as deter- minants of response. After reviewing available studies for each community type, we compare changes in species composition with grazing among community types. Comparisons are also made between southwestern communities with a relatively short history of grazing and communities of the adjacent Great Plains with a long evolutionary history of grazing. Evidence for grazing as a factor in shifts from grasslands to shrublands is considered. An appendix outlines a new community classification system, which is followed in describing grazing impacts in prior sections. -

Draft Biological Opinion Issued Under the Endangered Species Act, by the U.S
UNITED STATES ENVIRONMENTAL PROTECTION AGENCY WASHINGTON, D.C. 20460 OFFICE OF CHEMICAL SAFETY AND POLLUTION PREVENTION DRAFT BIOLOGICAL OPINION ISSUED UNDER THE ENDANGERED SPECIES ACT, BY THE U.S. FISH AND WILDLIFE SERVICE, RELATED TO THE POTENTIAL EFFECTS OF ROZOL PRAIRIE DOG BAIT, FOR THE CONTROL OF BLACK-TAILED PRAIRIE DOGS, ON THREATENED AND ENDANGERED WILDLIFE SPECIES COMMENTS ACCEPTED THROUGH FEBRUARY 17, 2012 EPA has initiated formal consultation with the U.S. Fish and Wildlife Service on the potential effects of Rozol Prairie Dog Bait, for the control of black-tailed prairie dogs, on wildlife species listed under the Endangered Species Act (ESA) as either threatened or endangered. The Biological Opinion relative to this consultation is posted here at www.epa.gov/espp and included in public docket EPA-HQ-OPP-2011-0909 at Regulations.gov so EPA may receive public input on any changes to this pesticide’s registration recommended by the U.S. Fish and Wildlife Service. BACKGROUND The ESA requires that federal agencies assess their “actions” to determine whether species listed as threatened or endangered under the ESA may be affected by those actions and/or whether critical habitat may be adversely modified. The registered uses of a pesticide constitute an EPA "action" under the ESA. If EPA determines a pesticide's registered uses are likely to adversely affect a federally listed threatened or endangered species (listed species) and/or modify its critical habitat, EPA initiates "formal consultation" with the U.S. Fish and Wildlife Service or the National Marine Fisheries Service (the Service(s)), as appropriate.
