Description

In Alberta, the loggerhead shrike is considered to be a Species of Special Concern. Since 1987, a prairie-wide roadside survey has been conducted every five years to monitor populations. This report summarizes results of the 2013 survey conducted in Alberta, and compares results with surveys conducted in 1987, 1998, 2003 and 2008.

Description

The greater sage-grouse, the largest species of grouse in North America, is listed as Endangered in Alberta. The goals of this recovery plan are to enhance and maintain habitat for the greater sage-grouse and to achieve recovery of the species to a level that provides for sustainable recreational viewing and hunting. The plan provides background information on the greater sage-grouse, 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 recover the species.

Description

A greater sage-grouse avian predator monitoring survey was needed to provide information on distribution, habitat associations, and baseline populations prior to initiation of a sage-grouse predator management program. The survey is designed for repeating in subsequent years once predator management is underway, thereby providing a potential measure of program effectiveness. This report describes the avian predator monitoring protocol and results of the 2013 survey. The survey area is within the current Alberta sage-grouse range, an area of ~3800 km in in the extreme south-eastern corner of the province. The monitoring protocol was designed for collection of data on avian predators, particularly corvids (American crows, black-billed magpies, common ravens). A systematic roadside survey was designed using a series of point samples contributing to a continuous observation zone along a series of 19 road-based transects, each of 10 kilometers length.

Greater sage-grouse (Centrocercus urophasianus) monitoring in southeast Alberta : 1968-2012

Description

Greater sage-grouse populations in Canada have declined by at least 80 per cent from historical levels. Threats to the Alberta population of sage-grouse include agricultural activities,... More ≫

Description

Greater sage-grouse populations in Canada have declined by at least 80 per cent from historical levels. Threats to the Alberta population of sage-grouse include agricultural activities, development in the energy sector, road and power line development, increasing predator populations and disease. Consistent monitoring is important so that population trends can be compared between years and linked to landscape activities. The objective of this report is to compile population monitoring efforts and corresponding methodologies that have been conducted and developed in Alberta since 1968 in order to provide an indication of trend for population decline.

The willow flycatcher in Alberta : habitat model and field surveys

The willow flycatcher inhabits shrub habitats in in many parts of North America, including the foothills of the Rocky Mountains of Alberta. In 2002, the Alberta Endangered Species Conservation... More ≫

Description

The willow flycatcher inhabits shrub habitats in in many parts of North America, including the foothills of the Rocky Mountains of Alberta. In 2002, the Alberta Endangered Species Conservation Committee declared that there was insufficient information on the species to determine an official risk status for the province. The purpose of this study was to help clarify the status of the willow flycatcher in Alberta by compiling all reliable historical records of the species in the province developing a model to identify potential breeding habitat and conducting field surveys to document occupancy of historical sites and of sites identified by the model as being suitable for breeding by willow flycatchers.

Description

The burrowing owl, a small owl that breeds in the open prairies of Alberta and Saskatchewan and winters in the southern US and Mexico, is listed as Endangered in both Canada and in Alberta. In Alberta, burrowing owl populations have shown a steep and continuing decline. This recovery plan provides background information on the burrowing owl, describes the threats facing the owl, outlines proposed strategies to address these threats, and presents an action plan that lists priority actions required to maintain or restore the species.
