Description

This wildlife status report looks at the long-billed curlew, the largest shorebird, and the most southerly breeding curlew, in North America. Once abundant over most of the prairie regions of the United States and Canada, populations have declined throughout most of the its breeding range since the early 1900s as a result of both overhunting and habitat loss. It is currently on the list of species that may be at risk of declining to nonviable population levels in Alberta. 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

This wildlife status report looks at the plains hognose snake, a subspecies of the western hognose snake and listed as a species that may be at risk of decline in Alberta. Current understanding of the population levels of the plains hognose snake in Alberta is limited by the secretive nature of the species and a lack of search effort to date. This report has been prepared as a review of current information relevant to determining the status of the snake. It 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

This wildlife status report looks at the Columbia spotted frog. Spotted frogs are endemic to northwestern North America and are most common in mountainous and high-altitude areas. In Alberta, spotted frogs occur within the Rocky Mountain and Foothills regions, where they inhabit cool, relatively permanent water sources. The Columbia spotted frog is included on the list of species that may be at risk in Alberta, due to the limited population information and reports of reduced numbers. This report reviews information on the species as a step in updating its status in the province. The 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

Management of environmental toxics is a major issue on the environmental policy agenda in Canada and around the world. There is growing evidence that long-term, low-level exposure can occur from the atmospheric transport of pollutants over long distances and that the substances are associated with effects on human health and the environment. No region, however remote, is assured of being safe from airborne toxic pollutants. Recognizing the significance of air toxics, it is important to document the Alberta air toxics management program. This document presents an overview of the existing management system for controlling industrial air toxics emissions.

Description

This study delineates flood hazard areas and determines design flood levels along Lamont Creek and two unnamed tributaries through Lamont. The study area includes an approximate 6 km reach of Lamont Creek and almost 3 km of combined tributary stream length. The design discharge for Lamont Creek ranges from 11.2 m³/s at the upstream study extent to 16.6 m³/s at the downstream extent, with the design discharge through Lamont between 12.7 m³/s and 13.0 m³/s. The design discharges for the upstream and downstream tributaries are 1.5 m³/s and 5.4 m³/s respectively. The study was prepared in March 1998. Flood information available after study completion may not be reflected in the current flood hazard study report or flood hazard mapping.

Description

This wildlife status report looks at the Canadian toad, one of three species of the genus Bufo found in Alberta (the other species being the western toad and the great plains toad). Once a common inhabitant of the northern interior plains, the population of this species in the province has experience a sharp decline recently, and populations in other areas of its range may be declining as well. This report summarizes current and historical information on the Canadian Toad in Alberta, as a step in reviewing the status of the species in the province. It 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.
