The Wild Horses of Assateague Island National Park Service Assateague Island U.S. Department of the Interior Assateague Island National Seashore Maryland and Virginia The Wild Horses of Assateague Island A National Treasure The wild horses of Assateague Island are descendents of domesticated animals brought to the island over 300 years ago. Horses tough enough to survive the scorching heat, abundant insects, stormy weather and poor quality food found on this windswept barrier island have formed a unique wild horse society. Enjoy their beauty from a distance, and you can help make sure these extraordinary wild horses will continue to thrive on Assateague Island. “My treasures do not click together or glitter.

  • 2020 Weather in Review: Assateague Island National Seashore
    National Park Service Northeast Coastal and Barrier Network U.S. Department of the Interior Inventory & Monitoring Division 2020 Weather in Review: Assateague Island National Seashore Weather and climate play significant roles in driving both physical and ecological processes. For example, the active processes that shape the North Atlantic coastline are largely the result of meteorological events such as wind- driven waves. For research and long-term ecological monitoring, weather and climate data provide the potential for correlations to be made with observed physical and ecological pattern data. This resource brief provides a summary of both historic and current (2020) weather data for Assateague Island National Seashore (ASIS), Maryland (MD). Because tide levels and wind can be significant for coastal parks, the annual water level and wind data are included. Temperature Overall, 2020 was the 2nd warmest year on record with an average temperature of 59.4 °F — 3.1 degrees above average (Figure 1). Spring nearly reached “above normal” temperatures, while summer, autumn, and winter seasons fell within “much above normal” temperatures. 2020 had the 2nd warmest winter on record. The warmest month was July with an average of 81 degrees — 4.7 degrees over the monthly average. Every month had higher than average temperatures, except May at 1.4 degrees below average (Table 1). Table1. Worcester County, Maryland average monthly, average annual, and departures from long- term average temperatures. Departures from average are based on a comparison of 2020 average temperatures to relevant averages from 1895-2019.

  • List of Horse Breeds 1 List of Horse Breeds
    List of horse breeds 1 List of horse breeds This page is a list of horse and pony breeds, and also includes terms used to describe types of horse that are not breeds but are commonly mistaken for breeds. While there is no scientifically accepted definition of the term "breed,"[1] a breed is defined generally as having distinct true-breeding characteristics over a number of generations; its members may be called "purebred". In most cases, bloodlines of horse breeds are recorded with a breed registry. However, in horses, the concept is somewhat flexible, as open stud books are created for developing horse breeds that are not yet fully true-breeding. Registries also are considered the authority as to whether a given breed is listed as Light or saddle horse breeds a "horse" or a "pony". There are also a number of "color breed", sport horse, and gaited horse registries for horses with various phenotypes or other traits, which admit any animal fitting a given set of physical characteristics, even if there is little or no evidence of the trait being a true-breeding characteristic. Other recording entities or specialty organizations may recognize horses from multiple breeds, thus, for the purposes of this article, such animals are classified as a "type" rather than a "breed". The breeds and types listed here are those that already have a Wikipedia article. For a more extensive list, see the List of all horse breeds in DAD-IS. Heavy or draft horse breeds For additional information, see horse breed, horse breeding and the individual articles listed below.

  • CHANGING PERCEPTIONS of WILD HORSES in the AMERICAN LANDSCAPE a Dissertation Submitted to the Gradu
    RUNNING WILD, RUNNING FREE?: CHANGING PERCEPTIONS OF WILD HORSES IN THE AMERICAN LANDSCAPE A Dissertation Submitted to the Graduate Faculty of the North Dakota State University of Agriculture and Applied Science By Andrea Lynn Mott In Partial Fulfillment for the Degree of DOCTOR OF PHILOSOPHY Major Department: History, Philosophy, and Religious Studies May 2014 Fargo, North Dakota North Dakota State University Graduate School Title Running Wild, Running Free: Changing Perceptions of Wild Horses in the American Landscape By Andrea Lynn Mott The Supervisory Committee certifies that this disquisition complies with North Dakota State University’s regulations and meets the accepted standards for the degree of DOCTOR OF PHILOSOPHY SUPERVISORY COMMITTEE: Thomas D. Isern Chair Angela Smith Cynthia Prescott Kevin Sedivec James F. Hoy Approved: July 11, 2014 John Cox Date Department Chair ABSTRACT Since the 1930s, wild horses have become a subject of public concern. They are often showcased as symbols representing the historic past of the western United States. More recently they have become symbols of a mythic, or imagined, west. Writers, scholars, politicians, advocates, ranchers, and land managers are among the few groups who have taken a role in the livelihood of these animals living freely on public rangelands. The protection movement that began in the 1950s and carried over into the 1970s ultimately resulted in the passage of the 1971 Wild Free-Roaming Horses and Burros Act. This act placed all wild horses living on public rangelands under the protection of the Bureau of Land Management and the Forest Service. Before this legislation individuals in the West could round up wild horses without interference.

  • Framing Contemporary U.S. Wild Horse and Burro Management Processes in a Dynamic Ecological, Sociological, and Political Environment
    Human–Wildlife Interactions 12(1):31–45, Spring 2018 Synthesis Framing contemporary U.S. wild horse and burro management processes in a dynamic ecological, sociological, and political environment J. Dˎ˛ˎ˔ Sˌˊ˜˝ˊ, Department of Ecosystem Science and Management, University of Wyoming, 1000 E. University Ave., Laramie, WY 82071, USA [email protected] Jˊˌ˘ˋ D. Hˎ˗˗˒ː, Department of Ecosystem Science and Management, University of Wyoming, 1000 E. University Ave., Laramie, WY 82071, USA Jˎˏˏ˛ˎˢ L. Bˎˌ˔, Department of Ecosystem Science and Management, University of Wyoming, 1000 E. University Ave., Laramie, WY 82071, USA Abstract: The Wild Free-Roaming Horses and Burros Act (WFRHBA) of 1971 established all “unbranded or unclaimed” equids on U.S. public lands as “living symbols of the historic and pioneer spirit of the West.” Today, >72,000 feral horses (Equus ferus caballus) and burros (E. asinus; WHB) live on western U.S. public rangelands. The number of WHBs exceeds the Bureau of Land Management’s maximum Appropriate Management Level (AML) of 26,715 by a factor of approximately 2.7 and has nearly doubled from 2007–2015. The AML was set to balance WHB numbers with rangeland health and support other uses such as wildlife habitat and livestock grazing. Thus, public land management agencies must manage WHB under the multiple-use context. This becomes more problematic when WHB populations go largely unmanaged and excessive equid grazing negatively impacts rangeland vegetation, native wildlife, and livestock forage. In addition, approximately 46,000 WHBs exist in off -range holding facilities, further straining federal budgets. Contemporary management actions are being constrained by: (1) litigation that has stymied federal government WFRHBA enforcement eff orts, (2) public emotional concerns that lack reconciliation with the current situation, and (3) increasing complexity in the laws and subsequent amendments shaping WHB management policy.

The seashore also provides high quality resource-compatible recreation experiences. To support these purposes, the National Park Service (NPS) has prepared a new general management plan (GMP) for the seashore, to replace the seashore’s existing GMP completed in 1982. The Draft General Management Plan/Environmental Impact Statement (Draft GMP/EIS) was available for public and agency review from January 29, 2016 through May 1, 2016. The document presents and evaluates four alternatives for management of the seashore. Alternative 1. The NPS would continue to manage resources and visitor uses as it does today. The seashore enabling legislation and the existing General Management Plan (NPS 1982) would continue to guide seashore management. The NPS would manage seashore resources and visitor use as it does today, with no major change in direction. Alternative 2. Most visitors would enjoy traditional beach recreation concentrated within a high density developed area accessible by private vehicle. This alternative would likely require significant manipulation of the natural environment to protect facilities and infrastructure in the island developed area.
