Mountain Plover population estimate is 11,000–14,000 birds (Plumb et al. Mountain Plover breeds on plains and short-grass prairies in a band to the east of the Rocky Mountains, chiefly in Montana, Wyoming and Colorado, reaching as far south as northern New Mexico and the top of the Texas pan-handle. Law and government. 2005). In the U.S., most are found in California with small numbers in Arizona and Texas. Sie wurde mit Hilfe von Flickr upload bot durch Pauk hierher übertragen. Max Post van der Burg. Other threats include loss of eggs and chicks to predation and introduction of tall woody species in preferred grassland habitats. We estimate the current mountain plover breeding population to be over 20,000 birds, more than double the estimate cited in our 2002 proposal. Current Mountain Plover population estimates range from 5000–11 000 (U.S. Condor 110:493–499. Abundance. The eastern plains of Colorado are considered the stronghold for Mountain Plovers. These two states are thought to support the majority of the global breeding population. Key Words: Charadrius montanus; elasticity; Mountain Plover; population growth; sensitivity; trend INTRODUCTION The Mountain Plover (Charadrius montanus) has received substantial conservation attention (Brown et al. Habitat loss due to conversion of shortgrass prairie to agricultural uses and declining prairie dog populations were major factors contributing to this decline. Mountain Plover. The purpose of this study was to survey known and prospective mountain plover nesting habitats in southeastern Alberta in order to search for and census breeding birds and to assess habitat potential and suitability. In Canada, reports are localized and irregular, with only 44 observations recorded since 1874. Estimates of mountain plover population size range from 12,500 to 28,000 individuals across their current range. Although BBS data for 1980-2006 suggest a +2.6% annual population change for the United States, earlier changes on both breeding and wintering grounds have reduced this once much more common species to a 1996 population of 8-10 thousand. Mountain Plover – Unlike most of these birds, which usually live along beaches and shores, Mountain Plovers live in meadows and fields in high elevations. mountain plover populations declined overall by 63 percent. Analysis of CBC data from 1980 - 1997 indicate 85% of nationwide CBC counts reporting Mountain Plovers were in California and … This annual rate equates to a cumulative decline of 81% over that period. [1] Google Scholar Page GW, Stenzel LE, … Mountain Plover population estimate is 11,000-14,000 birds (Plumb et al. Integrating info‐gap decision theory with robust population management: a case study using the Mountain Plover. An analysis of the potential threats to the mountain plover does not indicate the species is in danger of extinction or likely to become endangered within the foreseeable future. The Mountain Plover (Charadrius montanus) is a Great Plains species inhabiting agricultural fields and native short-grass prairie. In March 2009, a multi-agency report, the first of its kind, issued by the Cornell University Lab of Ornithology in conjunction with federal agencies and other organizations, indicated that the Mountain Plover is one of the birds showing serious declines in population.

Es-timates of local abundance are available for key breeding sites and are usually extrapolat-ed from density estimates. An unknown proportion of the continental population winters in northern Mexico (Aou 1983). distribution and population size of Mountain Plover in Nebraska. Permanent point count transects were established in 1992 in central, northeastern and southwestern Montana to monitor mountain plover population trends in these areas. Mountain Plover Printer friendly versionPrinter friendly version Species of Special Concern Charadrius montanus - Mountain Plover being tagged, credit Tyler BaskfieldDescription: Colorado is the primary breeding ground for the mountain plover, more than half of the world's population nests in the state. United States reporting Mountain Plovers, and in both periods for 95% of the total plovers tallied (Hunting et al.

From 1968–2015, annual Wyoming Breeding Bird Survey (BBS) detections of Mountain Plover ranged from 0 to 20 Wyoming Species Account Page 3 of 8 (average = 5), with 2 recorded in 2015 15. Oyler-McCance SJ, John JS, Kysela RF, Knopf FL (2008) Population structure of mountain plover as determined using nuclear microsatellites. POPULATION TREND: Recent analysis of the USFWS Breeding Bird Survey (BBS) data suggest that Mountain Plover populations have declined at an annual rate of 3.7% over the last 30 years which represents a cumulative decline of 63% during the last 25 years (Knopf 1995). Adult density was 2.0 ? Outside of these areas, the abundance and distribution of smaller, isolated populations may be strongly influenced by range management and variation in annual precipitation. Breeding Mountain Plovers are relatively inconspicuous and easily overlooked. Endangered Species Act (ESA) and then subsequently proposed for listing as a threatened species. Es timates of local abundance are available for key breeding sites and are usually extrapolat ed from density estimates. The mountain plover has two core breeding populations in North America, one in Colorado and another in Montana. Mountain Plovers are, however, poorly sampled by such roadside surveys because they are relatively inconspicuous and, thus, easily overlooked. We used a stage-specific matrix model to study the influence of vital rates, e.g., juvenile and adult annual survival, on population growth rate in the Mountain Plover at two breeding sites in Colorado, South Park and Eastern Colorado, and one breeding site in Montana, USA. 2012, Pierce et al. The status of wintering Mountain Plover populations is poorly understood. Breeding Bird Survey (BBS) … Studies show that annual mortality rates exceeding 25% result in Mountain Lion population decline. Extrapolation of these densities indicates a Mountain Plover population of 8,577 (95% CI: 7,511–35,130). 2 3 SUMMARY OF KEY COMPONENTS FOR CONSERVATION OF THE MOUNTAIN PLOVER The mountain plover (Charadrius montanus) is a local and declining bird throughout its range. The Mpumalanga Province's legislation is an amalgam of national and regional legislation promulgated before the establishment of the province on 27 April … To the east of this landscape, the plover is found most predictably on prairie-dog (Cynomys spp.) Black‐tailed prairie dogs declined sharply in the mid‐1990s in response to an outbreak of sylvatic plague, but their numbers have steadily increased since 1996 in concert with increases in plovers. Prairie dogs create unique patches of habitat ideal for mountain plovers. Google Scholar Page GW, Stenzel LE, Shuford WD, Bruce CR (1991) Distribution and abundance of the snowy plover on its western North American breeding grounds. (Cougar Management Guidelines, chapter 4). Mountain Plover populations in the U.S. have been surveyed through the BBS. The U.S. Knopf (1996) estimated the California wintering population to be 4000 to 7000 birds or 50% to 88% of the entire world population. Population Status. Between 1966 and 1991, the continental population of the Mountain Plover declined an estimated 63 percent. Shop Montenegro Capital Population bath mats designed by independent artists. The population is estimated at between 5,000 and 11,000 adult birds. J Field Ornithol 62:245–255 . Fish and Wildlife Service designated the mountain plover as a candidate species under the U.S. 2005). A population composed of younger individuals indicates that the Mountain Lions, who live in the wild 12 to 13 years, do not survive long and are being killed at an average age of 2.86 years (Table 5). Mountain Plover populations declined by an estimated 3.4% per year between 1968 and 2015, according to the North American Breeding Bird Survey. The current total population is estimated to be between 8,000 and 10,000 individuals. Mountain Plover is classed as “Near Threatened” with a population of only 5,000 – 10,000 individuals. Some examples of these formations include serpentines of Barberton Mountains, norites of Sekhukhuneland, quartzites of Blyde River Canyon, and the dolomites in the northern plateaus. Summary; Detailed Information; Description. Mountain plover habitat and population surveys in Alberta, 2001. The NPP made a concerted effort to gain access to private lands in the southwestern panhandle before initiating systematic research and monitoring activities focused on Mountain Plover ecology. The Mountain Plover (Charadrius montanus) is a species that inhabits cold, xeric-shrub landscapes of the western United States where it breeds in low-density, scattered populations primarily in Colorado, New Mexico, and Wyo- ming. Mountain Plovers are medium-sized shorebirds that lack the distinctive neckbands typical of many other plovers. These little birds love to nest in prairie dog towns! In parts of its breeding range the mountain plover selectively nests in prairie dog towns. However, they do not live in the mountains, but rather the foothills and tablelands. The Mountain Plover population has been suggested to be declining over the past century, with a loss of nearly two-thirds of the population (Knopf 1996a).
