Introduction

In Alberta, greater sage-grouse (Centrocercus urophasianus) has been on Canada’s endangered species list since 1998. And yet nothing has been done to slow the destruction of sage-grouse habitat, and the species' relentless slide towards extinction in Alberta."This will be the first case where the oil and gas industry has caused the extirpation of a species from Alberta," according to University of Alberta scientist Mark Boyce. The sage-grouse is the largest of all North American grouse and it is dependent on silver sagebrush (Artemisia cana) for food and cover. Greater sage-grouse are most well known for their spectacular courtship displays on dancing grounds (leks) in the spring. Now found only in the extreme southeast corner of the province, east of Pakowki Lake and south of Cypress Hills; its habitat consists primarily of silver sagebrush flats that exist only within extensive areas of the Dry Mixedgrass region.

There has been a significant loss (>90%) of greater sage-grouse silver sagebrush habitat in southeastern Alberta. By 1968, the sage grouse sagebrush habitat had decreased to only 4000 km². The greater sage-grouse population declined drastically over the past several decades with decreases of 80 percent between 1968 (2,462 birds) and 1997 (542 birds). As of the spring of 2011, there were only 13 males dancing at 6 active leks and the total population of greater sage-grouse in Alberta was estimated at maybe 40 birds.The Alberta government has monitored this precipitous decline, while doing nothing to protect sage-grouse habitat.

AWA Position:
Greater sage-grouse need large blocks of unfragmented prairie wildland to thrive. A draft Canadian recovery strategy failed to identify critical habitat, despite there being sufficient scientific data to do so. In 2009, AWA and other environmental organizations won a successful court case to compel the federal minister to recognize critical habitat for sage-grouse. But protection of this habitat still seems a long way away. We continue to advocate for the protection of the Cypress Hills-Sage Creek area of south-eastern Alberta, one of the largest, least fragmented and most diverse ecosystems on the northern glaciated plains of North America. It is home to many species at risk, including greater sage-grouse.

In September 2011, AWA hosted the Emergency Sage-Grouse summit, and was signatory to an emergency communique calling for immediate action to protect sage-grouse habitat.

On November 23, 2011, Ecojustice submitted a legal petition to federal Environment Minister Peter Kent on behalf of AWA and 11 other national and international environmental groups. The petition calls for Minister Kent to issue an emergency protection order for the sage-grouse and to stop further human disturbance of the habitat upon which the species survival depends.
