Description

The 2000 edition of the General Status of Alberta Wild Species represents a substantial improvement in the knowledge base of wild species in Alberta. Preliminary status assessments were prepared for 4 735 species of birds, mammals, herpetiles (amphibians and reptiles), freshwater fish, molluscs (gastropods and bivalves), odonates (dragonflies and damselflies), lepidopterans (butterflies and skippers), vascular plants, nonvascular plants and fungi in Alberta. Of these groups, Alberta, along with all other provinces and territories, agreed to report on eight to Environment Canada so that a national evaluation could be undertaken (see Background of the Present General Status Evaluation Exercise). These groups included the birds, mammals, reptiles, amphibians, freshwater fish, butterflies, orchids and ferns. The status of species in these categories is provided here.

Description

In this evaluation, all relevant current data, information, and knowledge available were summarized for vertebrate, selected invertebrate, and vascular plant species in Alberta using seven key criteria as follows: Population size; Number of occurrences; Distribution. Trend in population size; Trend in distribution; Threats to population; Threats to habitat. Each criterion was rated on a scale of "A" to "D," in which "A" is of the most concern and "D" the least.

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.
