mountain plover population

Texas Mountain Lions - Age Structure. 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. 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. Breeding Bird Survey (BBS) … Permanent point count transects were established in 1992 in central, northeastern and southwestern Montana to monitor mountain plover population trends in these areas. 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). However, they do not live in the mountains, but rather the foothills and tablelands. In Canada, they are at the northern periphery of their range and are restricted to extreme southeastern Alberta and southwestern Saskatchewan. 2005). The sustained historic population decline of the mountain plover has been attributed to habitat loss. Habitat loss due to conversion of shortgrass prairie to agricultural uses and declining prairie dog populations were major factors contributing to this decline. Extrapolation of these densities indicates a Mountain Plover population of 8,577 (95% CI: 7,511–35,130). Mountain Plover is classed as “Near Threatened” with a population of only 5,000 – 10,000 individuals. In southern Phillips County, the population trend of mountain plovers closely matched the trend in the area occupied by black‐tailed prairie dogs. This annual rate equates to a cumulative decline of 81% over that period. The mountain plover has two core breeding populations in North America, one in Colorado and another in Montana. The eastern plains of Colorado are considered the stronghold for Mountain Plovers. 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. 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.

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. [1] Mountain Plover populations in the U.S. have been surveyed through the BBS. The U.S. Condor 110:493–499. 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. Population Status. Knopf (1996) estimated the California wintering population to be 4000 to 7000 birds or 50% to 88% of the entire world population. 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. It was proposed for listing … Mountain Plover – Unlike most of these birds, which usually live along beaches and shores, Mountain Plovers live in meadows and fields in high elevations. J Field Ornithol 62:245–255 . 2001). We estimate the current mountain plover breeding population to be over 20,000 birds, more than double the estimate cited in our 2002 proposal. Photo taken by author. Other threats include loss of eggs and chicks to predation and introduction of tall woody species in preferred grassland habitats. Studies show that annual mortality rates exceeding 25% result in Mountain Lion population decline. 2012, Pierce et al. Mountain Plover populations declined by an estimated 3.4% per year between 1968 and 2015, according to the North American Breeding Bird Survey. Shop Montenegro Capital Population bath mats designed by independent artists. 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. (Cougar Management Guidelines, chapter 4). 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). Adult density was 2.0 ? Oyler-McCance SJ, John JS, Kysela RF, Knopf FL (2008) Population structure of mountain plover as determined using nuclear microsatellites. Estimates of mountain plover population size range from 12,500 to 28,000 individuals across their current range. Mountain Plover population estimate is 11,000-14,000 birds (Plumb et al. Trends produced through these surveys should be viewed with some caution because few routes have been consistently surveyed since the 1960s.

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. Mountain Plover arrives in Wyoming for the breeding season by late March or early April, and ... and in 2003 the state population was estimated to be 3,393 12. Law and government. SPECIES ASSESSMENT FOR MOUNTAIN PLOVER (CHARADRIUS MONTANUS) IN WYOMINGprepared by HAMILTON SMITH 1 AND DOUGLAS A. KEINATH 2 1 Wyoming Natural Diversity Database, University of Wyoming, 1000 E.

The Mpumalanga Province's legislation is an amalgam of national and regional legislation promulgated before the establishment of the province on 27 April … The current total population is estimated to be between 8,000 and 10,000 individuals. They winter in Arizona, California and Texas. Between 1966 and 1991, the continental population of the Mountain Plover declined an estimated 63 percent. The population is estimated at between 5,000 and 11,000 adult birds. Executive Summary.

Mountain Plovers are medium-sized shorebirds that lack the distinctive neckbands typical of many other plovers. 2005). Endangered Species Act (ESA) and then subsequently proposed for listing as a threatened species. Fish and Wildlife Service 2003) having declined 60% in a recent 30-year period due to significant habitat loss and fragmentation (Leachman and Osmundson 1990, Knopf 1996). Mountain plover habitat and population surveys in Alberta, 2001. Temperature has been previously linked with Mountain Plover nest survival (Dreitz et al. Mountain Plovers are, however, poorly sampled by such roadside surveys because they are relatively inconspicuous and, thus, easily overlooked. Integrating info‐gap decision theory with robust population management: a case study using the Mountain Plover. 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. Abundance. In parts of its breeding range the mountain plover selectively nests in prairie dog towns. Max Post van der Burg. The Mountain Plover (Charadrius montanus) is a Great Plains species inhabiting agricultural fields and native short-grass prairie. dissertation was entitled “Population biology of mountain plovers in southern Phillips County, Montana.” COVER PHOTO CREDIT Mountain plover (Charadrius montanus). 2019), but the role of extreme minimum or maximum temperatures may vary because Mountain Plovers inhabit a fairly wide climatic envelope given their limited geographic range (Knopf and Wunder 2006). Results of variance component analysis suggest that the amount of prairie dog colony within 500 m of the plot explained the most process variance in Mountain Plover abundance estimates (11.32% of variance explained). To the east of this landscape, the plover is found most predictably on prairie-dog (Cynomys spp.) 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. November 2012, 22:29 – war sie bei Flickr unter der unten stehenden Lizenz freigegeben. Mountain Plover. Prairie dogs create unique patches of habitat ideal for mountain plovers. Es-timates of local abundance are available for key breeding sites and are usually extrapolat-ed from density estimates. Mountain Plover population estimate is 11,000–14,000 birds (Plumb et al. 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. These two states are thought to support the majority of the global breeding population. 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). The status of wintering Mountain Plover populations is poorly understood. Analysis of CBC data from 1980 - 1997 indicate 85% of nationwide CBC counts reporting Mountain Plovers were in California and … Summary; Detailed Information; Description.

These little birds love to nest in prairie dog towns! mountain plover populations declined overall by 63 percent. At the time, these were considered to be Montana’s 2nd, 3rd and 4th largest mountain plover populations. 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. In Canada, reports are localized and irregular, with only 44 observations recorded since 1874. 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. Fish and Wildlife Service designated the mountain plover as a candidate species under the U.S. United States reporting Mountain Plovers, and in both periods for 95% of the total plovers tallied (Hunting et al.
