DOI-BLM-UT-W010-2014-0021-EA 1 PURPOSE & NEED 1.1 Introduction This Environmental Assessment (EA) has been prepared to disclose and analyze the environmental consequences of the Onaqui Mountain Herd Management Area Fertility Control project as proposed by the Bureau of Land Management (BLM) Salt Lake Field Office (SLFO). This EA is a site-specific analysis of potential impacts that could result with the implementation of a proposed action or alternatives to the proposed action. The EA assists the BLM in project planning and ensuring compliance with the National Environmental Policy Act (NEPA), and in making a determination as to whether any “significant” impacts could result from the analyzed actions. “Significance” is defined by NEPA and is found in regulation 40 CFR 1508.27. An EA provides evidence for determining whether to prepare an Environmental Impact Statement (EIS) or a statement of “Finding of No Significant Impact” (FONSI). If the decision maker determines that this project has “significant” impacts following the analysis in the EA, then an EIS would be prepared for the project. If not, a Decision Record (DR) may be signed for the EA approving the selected alternative, whether the proposed action or another alternative. A DR, including a FONSI statement, documents the reasons why implementation of the selected alternative would not result in “significant” environmental impacts (effects) beyond those already addressed in Pony Express Resource Management Plan (January 1990), as amended. 1.2 Background The SLFO proposes to treat mares within the Onaqui Herd Management Area (HMA) with the fertility control drug ZonaStat-H which is the liquid native Porcine Zona Pellucida (PZP). This drug is federally approved by the Environmental Protection Agency (EPA) and registered under the number 86833–1. PZP is a naturally occurring pig protein which degrades quickly in the environment. If eaten, it is digested like any other protein and cannot pass through the food chain (Kirkpatrick et al. 2006). The analysis area is located in Townships 5 to 10 South, Ranges 5 to 9 West, various sections, Salt Lake Meridian, Tooele County, Utah (Map, Appendix A). 1 May 2015 Additional information

  • Nature Mapping Day 5 Identifying Birds: Anatomy
    Nature Mapping Day 5 Identifying Birds: Anatomy Did you see any birds during your nature observation? In Washington State, we observe birds more than any other type of wild vertebrate (animals with a backbone). Think about it. Most people see or hear a wild bird on most days of their life. That can not be said of wild mammals, reptiles, or fish. Once you start noticing birds, most people want to be able to identify what birds they are observing. Often, one of the first things a person notices about a bird is their colors and patterns. Those are called field marks. When you are using field marks, it helps if you know a little bird anatomy. Ornithologists (people who study birds) talk about parts of a bird by dividing its body into regions. The main areas are beak (or bill), head, back, throat, breast, wings, tail, and legs. Many of these regions are divided still further. Purpose: At the end of this lesson I can say with confidence . 1) I can create and use a diagram of a bird’s feathers. Directions: 1) Click on the link below to go to TheCornellLab Bird Academy to learn All About Bird Anatomy. a) https://academy.allaboutbirds.org/features/birdanatomy/ i) Click the -GO!- button to enter the interactive learning tool. ii) Turn each system on or off by using the color-coded boxes. iii) Learn about the individual parts in a system by clicking on the box. The part will be highlighted on the bird diagram. iv) Click on the highlighted section of the bird diagram to learn the function or description of each part and how to pronounce its name.

  • Common Birds of the Estero Bay Area
    Common Birds of the Estero Bay Area Jeremy Beaulieu Lisa Andreano Michael Walgren Introduction The following is a guide to the common birds of the Estero Bay Area. Brief descriptions are provided as well as active months and status listings. Photos are primarily courtesy of Greg Smith. Species are arranged by family according to the Sibley Guide to Birds (2000). Gaviidae Red-throated Loon Gavia stellata Occurrence: Common Active Months: November-April Federal Status: None State/Audubon Status: None Description: A small loon seldom seen far from salt water. In the non-breeding season they have a grey face and red throat. They have a long slender dark bill and white speckling on their dark back. Information: These birds are winter residents to the Central Coast. Wintering Red- throated Loons can gather in large numbers in Morro Bay if food is abundant. They are common on salt water of all depths but frequently forage in shallow bays and estuaries rather than far out at sea. Because their legs are located so far back, loons have difficulty walking on land and are rarely found far from water. Most loons must paddle furiously across the surface of the water before becoming airborne, but these small loons can practically spring directly into the air from land, a useful ability on its artic tundra breeding grounds. Pacific Loon Gavia pacifica Occurrence: Common Active Months: November-April Federal Status: None State/Audubon Status: None Description: The Pacific Loon has a shorter neck than the Red-throated Loon. The bill is very straight and the head is very smoothly rounded.

SUMMARY The present Republic of Yemen (RDY) was formed in 1991 with the union of two Yemens namely, Yemen Arab Republic (YAR) or North Yemen and the Peoples Democratic Republic of Yemen (PDRY) or South Yemen. Studies on livestock breeds were undertaken in the former YAR during 1985-87 under the FAO Project UTFN/YEM/011. It was supplemented with a rapid survey for the former PDRY in 1991 by the senior author (HUH) under the FAO Project UTF/ PDY/013. The information on goats in Yemen has recently been published in FAO Animal Genetic Resources Information No: 8 ( 1992). Here is presented the information of the Yemeni sheep and cattle population. RESUME La République du Yemen actuelle (RDY) a été formée en 1991 par l’union des deux Yemen, la République du Yemen Arabe (YAR) ou Nord Yemen et la République Démocratique Populaire du Yemen (PDRY) ou Sud Yemen.

  • Texas Wildlife Identification Guide
    TEXAS WILDLIFE IDENTIFICATION GUIDE A guide to game animals, game birds, furbearers and other wildlife of Texas. INTRODUCTION Texas game animals, game birds, furbearers and other wildlife are important for many reasons. They provide countless hours of viewing and recreational opportunities. They benefit the Texas economy through hunting and “nature tourism” such as birdwatching. Commercial businesses that provide birdseed, dry corn and native landscaping may be devoted solely to attracting many of the animals found in this book. Local hunting and trapping economies, guiding operations and hunting leases have prospered because of the abun- dance of these animals in Texas. The Texas Parks and Wildlife Department benefits because of hunting license sales, but it uses these funds to research, manage and protect all wildlife populations – not just game animals. Game animals provide humans with cultural, social, aesthetic and spiritual pleasures found in wildlife art, taxidermy and historical artifacts. Conservation organiza- tions dedicated to individual species such as quail, turkey and deer, have funded thousands of wildlife projects throughout North America, demonstrating the mystique game animals have on people. Animals referenced in this pocket guide exist because their habitat exists in Texas. Habitat is food, cover, water and space, all suitably arranged. They are part of a vast food chain or web that includes thousands more species of wildlife such as the insects, non-game animals, fish and i rare/endangered species. Active management of wild landscapes is the primary means to continue having abundant populations of wildlife in Texas. Preservation of rare and endangered habitat is one way of saving some species of wildlife such as the migratory whooping crane that makes Texas its home in the winter.

Still, their welfare varies greatly because of several factors. These hybrids have anatomy, health, nutritional, and behavioral particularities that are distinct from those of donkeys or horses. Their behavior can pose challenges to providing routine care and treatment during times of disease. Abusive treatment can result from those who have little understanding of learning theory or body language. Hence, an overview of studies and field observations can offer solutions for welfare enhancement. According to literature, participatory surveys and behavioral assessments across several countries, mule owners and handlers find it easier to interact with their animal as compared to allowing a stranger to do so.
