Description

The ferruginous hawk is a large raptor within the Grassland Natural Region of Alberta; inhabiting areas dominated by native prairie. The provincial ferruginous hawk population has been estimated every five years since 1982, except between the years 1993 and 1999. The population estimate is based on the number of active nests detected during each inventory year. During the 2010 inventory, a population estimate of 643 ± 169 breeding pairs of ferruginous hawks was calculated. This population estimate is similar to the 2005 estimate, which implies that the population is relatively stable at low numbers. Overall, Alberta's ferruginous hawk population still remains significantly lower than the 1992, and thus, it is essential to take management actions to assist with the recovery of this species.

Description

This wildlife status report looks at the pygmy whitefish, a small, slim whitefish in Alberta that has been collected in specific habitats from only two locations in the province: Upper Waterton Lake and a restricted portion of the upper Athabasca River. Recent surveys indicate that it appears to be relatively common in Upper Waterton Lake and relatively uncommon in the Athabasca River. This report is part of the Alberta Wildlife Status Report series, which provides comprehensive summaries of selected wildlife species intended to be useful to those managing populations of species and their habitats, and to help identify species that may be formally designated as endangered or threatened.

Description

The Weidemeyer's admiral is a Species of Special Concern in Alberta because its breeding range is limited and it is found only in the Milk River Basin of southern Alberta. This plan provides background information on the species and outlines a set of objectives and management actions to help meet the goal of maintaining current distribution and breeding populations of the butterfly in Alberta. Conservation management plans are developed for Species of Special Concern in Alberta, to provide guidance for land and resource management decisions that affect the species and their habitat. They are intended to be a resource tool for provincial and regional fish and wildlife, land and resource management staff.

Description

Porsild's bryum is a disjunct moss found in British Columbia, Alberta, Newfoundland and Nunavut. In Alberta, where it is listed as Endangered, it is found in 12 small subpopulations in the Rockies from Kananaskis to Willmore Wilderness Park. The goal of this recovery plan is to ensure long-term persistence of all current natural populations of Porsild's bryum, and maintain population size at all sites within its Alberta range. The plan provides background information on Porsild's bryum, describes the threats facing the species, outlines proposed strategies to address these threats, and presents an action plan that lists priority actions required to maintain and restore the species.

Description

The long-billed curlew is the largest member of the sandpiper family and is distinguishable by its long downward curved bill and large size. It has been designated a Species of Special Concern in Alberta and Canada due to the contraction of its range and small, possibly declining, population. Habitat alteration is the primary threat to this species. This plan provides background information on the species and outlines a set of objectives and management actions to help meet the goal of maintaining the current distribution and population of long-billed curlew in Alberta. Conservation management plans are developed for Species of Special Concern in Alberta, to provide guidance for land and resource management decisions that affect the species and their habitat. They are intended to be a resource tool for provincial and regional fish and wildlife, land and resource management staff.

Description

The Sprague's pipit is a small, ground-nesting songbird which, in Alberta, is found almost exclusively on native prairie. The bird is designated a Species of Special Concern in Alberta due to its large historic population decline and potential for continuing habitat alteration. This plan provides background information on the species and outlines a set of objectives and management actions to help meet the goals of returning Sprague's pipit populations to the mean abundance levels between 1980 and 1989, and conserving and maintaining remaining native prairie within the historic range of the species in Alberta. Conservation management plans are developed for Species of Special Concern in Alberta, to provide guidance for land and resource management decisions that affect the species and their habitat. They are intended to be a resource tool for provincial and regional fish and wildlife, land and resource management staff.

Description

The long-toed salamander has been designated a Species of Special Concern in Alberta because it has a limited breeding range, populations are isolated and discontinuously distributed, it appears to be vulnerable to various types of habitat disturbance, and some populations may be declining. This plan provides background information on the species and outlines a set of objectives and management actions to help meet the goal of maintaining current distribution and breeding populations of long-toed salamanders in Alberta. Conservation management plans are developed for Species of Special Concern in Alberta, to provide guidance for land and resource management decisions that affect the species and their habitat. They are intended to be a resource tool for provincial and regional fish and wildlife, land and resource management staff.

Description

The harlequin duck is a sea duck that comes to Alberta to breed in the mountains and foothills, nesting along swiftly-flowing clear mountain streams where there is suitable nesting cover. It has been designated a Species of Special Concern in Alberta because it has narrow breeding habit requirements, a relatively small population size, and is sensitive to disturbance during breeding. This plan provides background information on the species and outlines a set of objectives and management actions to help meet the goal of maintaining the current distribution and occupation of breeding streams of harlequin ducks in Alberta. Conservation management plans are developed for Species of Special Concern in Alberta, to provide guidance for land and resource management decisions that affect the species and their habitat. They are intended to be a resource tool for provincial and regional fish and wildlife, land and resource management staff.
