Description

The status and distribution of many of Alberta's small mammals is unknown. This report summarizes the information available on 15 of these species, as a step in updating their status for The General Status of Alberta Wild Species 2000. Much of the information in this report was gathered from North American museums. Additional data were collected from reports that contained quantitative data for locations and date, as well as reliable species identification. Much of this information was gathered from studies which analyzed small mammal remains found in owl pellets. In total, over 1000 records were amassed from the various sources. All of these observations have been stored in the Biodiversity/Species Observation Database.

Status of the Cape May warbler (Dendroica tigrina) in Alberta

Description

This wildlife status report looks at the Cape May warbler, a migrant songbird that breeds across the boreal forests of Canada and the northeastern United States and winters in the West Indies and the east coast of Central America. The Cape May warbler is uncommon in most areas of Alberta and concerns over the degradation and loss of suitable breeding habitat in the province have led to its inclusion on the list of species that may be at risk. 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.

An evaluation of grizzly bear - human conflict in the northwest boreal region of Alberta (1991 to 2000) and potential mitigation

Description

In parts of the Northwest Boreal Region the grizzly bear is experiencing an increasing number of conflicts with humans, which have led to an increase in the number of public complaints and the number of grizzlies translocated or destroyed. This project was initiated to identify the factors that contribute to human-grizzly conflicts and to offer possible solutions. The most common causes of conflict were found to be field grain, livestock predation, domestic carcasses, and garbage. Several practices are recommended, including a carcass pick-up service, a bear education program, and several aversive conditioning techniques. These practices, initiated in a timely fashion, consistently maintained, and applied with an understanding of bear behaviour, should reduce conflict.

Description

This monitoring plan was designed to address three objectives. First, to make a preliminary assessment of the status of all potential harlequin duck breeding streams in the bow Region of Kananaskis Country, and describe methods to continue this assessment with field work over a number of years. Second, to describe and assess the methods used to determine the population status of the ducks on the Elbow and Kananskis rivers; to assess the effectiveness of helicopter surveys used in central Alberta; and to recommend which methods to use to continue to estimate population size. Third, to describe and assess methods used to determine productivity of harlequin ducks on the Elbow and Kananskis rivers, and their validity for other streams.

Description

Previous bat studies conducted in Alberta have been limited in geographical scope and no long-term, province-wide, standardized monitoring has ever been conducted. A standard protocol for surveying bats in Alberta was recently developed, with the goal of ensuring that all studies on bats in the province collect the same types of information in standard formats. The report presents the results of a study conducted with the dual purpose of surveying bats in central and northwestern Alberta, while also performing a field test of the newly developed protocols.

Description

Since 1970 national surveys of the peregrine falcon population have been conducted every five years. Alberta has committed to surveying peregrines on a provincial basis as a component of the national survey. In 2000, Alberta was surveyed comprehensively as part of the 2000 national survey. This report presents the findings of the 2000 survey. Provincially, 48 territorial pairs were located: 23 in the southern Alberta population and 25 pairs in the northern population.

Description

This wildlife status report looks at the bay-breasted warbler, a migrant songbird that breeds across the boreal forests of Canada and the northeastern United States and winters in Panama and northern South America. It is uncommon in most areas of Alberta and may be at risk in the province due to habitat loss. 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 Northern Watershed Project is a four-year, multi-stakeholder initiative. Its goal is to develop predictive models relating the cumulative ecological effects of a suite of watershed disturbances to fish community structure. The third of the three components of this project is to model the cumulative effects of landscape disturbances on fish communities in the Kakwa and Simonette watersheds. This document provides a summary of activities completed within this component of the project for the period of April 1, 2000 to March 31, 2001.

Colonial nesting waterbird survey in the northwest boreal region - 2000

Description

Wildlife management agencies need current knowledge on colony locations, status and trends of colonial nesting waterbirds to assist them in making decisions about protection through population and land use management. This survey was conducted to obtain data on location and status of colonial waterbirds in the Northwest Boreal Region in recognition of their sensitivity and public concern. The survey results have been provided to Natural Resources Service wildlife biologists and entered into the Biodiversity/Species Observation Database so that appropriate management strategies can be implemented. Crown lands that contain waterbird colonies will be recommended for protection from disturbances through the application of appropriate protective notations (PNTs) or seasonal sanctuaries.

Distribution and relative abundance of the shortjaw cisco (Coregonus zenithicus) in Alberta

Description

Barrow Lake, located about 60 km north of Fort Chipewyan, contains the only verified population of shortjaw cisco in Alberta. A specific search for shortjaw cisco in the area around Barrow Lake was undertaken in an effort to gather additional information on its extent of occurrence in Alberta. Eight lakes in the region north of Lake Athabasca and east of Wood Buffalo National Park were surveyed by gillnetting in July and August 2000. No new populations of shortjaw cisco were found at these sites. Seven other nearby lakes had been sampled in 1996 and 1997 with similar results. Catch-per-unit-effort data from Barrow Lake suggest that this population of shortjaw cisco appears to have been stable over at least the past five years and probably the last 30 years. However, further monitoring is required to determine population trends with a scientifically acceptable level of confidence.
