Description

The purpose of this study was to assess the current distribution and abundance of eight disjunct butterfly populations that are closely associated with the native grasslands of the Peace River Parkland natural sub-region of northwestern Alberta and to make recommendations for further monitoring and management. All of the butterfly populations surveyed have very narrow geographic ranges and specific habitat requirements making them particularly susceptible to habitat loss.

Western (Aechmophorus occidentalis) and eared (Podiceps nigricollis) grebes of central Alberta : inventory, survey techniques, and management concerns

Description

This project focused on western grebes and eared grebes inhabiting the Stony Plain area, which is within the Parkland and Boreal natural regions of central Alberta. These grebe species have a wide distribution across western and central North America, yet indications are that they may be declining and could become threatened over the long-term. Relatively little research and monitoring attention has been directed toward these species. To address some of these concerns, surveys were conducted to locate grebe colonies, estimate population sizes, and assess their reproductive success. Various survey methods were also developed, tested, and evaluated, thereby providing a framework for future surveys. In doing so, trend data can now be gathered for western and eared grebes, which will enable local and regional status assessment. Management implications are also provided in this report.

Description

Several reports have been prepared on the status of Alberta's native plant species. More recently, nonvascular plants have been given some attention and tracking lists have been developed. There is a relatively good information base for rare vascular species but a very limited one for rare non-vascular plants. This report analyzes the vascular plant species and discusses potential approaches to research, monitoring and conservation of vascular and non-vascular plants in the Grassland Natural Region. There is a fundamental recognition that habitat or landscape level approaches are preferred but that some single species attention may still be required. One hundred and twelve vascular plant species were selected for detailed analysis and preparation of protocols based on their distribution within the Grassland Natural Region.

Survey of the bats of Central and northwestern Alberta

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... More ≫

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.

Western blue flag (Iris missouriensis) in Alberta : a census of naturally occurring populations for 2000

Description

In Canada, all of the known naturally occurring populations of western blue flag occur in the Cardston area of southwestern Alberta, within 10 km of the United States border. Prior to this project, six sites of naturally occurring western blue flag were confirmed in Alberta. As a result of investigations carried out in 2000, it is believed that only four of the six remain. Two new sites were discovered near previously known locations. Inventories conducted at all sites in 2000 revealed a total of 8705 stems. Information is inadequate to determine populations trends at most sites; however, western blue flag appears to be declining at a site in Police Outpost Provincial Park.
