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.

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.
