This exhaustively researched project brings together for the first time a complete listing of Alberta's rare vascular plants with detailed plant descriptions, habitat information and notes of special interest. Accompanied by numerous colour photographs, B&W illustrations and frequency maps, this text is essential for naturalists, botanists, students, and others interested in the flora of Alberta.

The Southern Alberta Sustainability Strategy (SASS) is part of Alberta Environment's regional sustainability strategy for southern Alberta. The purpose is to develop a vision of the future of Southern Alberta and the desired environmental, social and economic benefits for the region, and then address the issues and follow a plan to achieve the vision. ALCES (A Landscape Cumulative Effects Simulator) is a computer simulation model that was chosen as one of the tools in developing the strategy. ALCES has been customized for SASS to operate with 12 sub-models. This document consists of independent reviews of four sub-models: wildlife and biodiversity; invasion of non-native plant species; natural disturbance (fire and insects), and rangeland plant community structure. The reviewers assessed the sub-model documentation using criteria which include judging the soundness of the methods used, and appropriate use of data. A compiler's summary and comments completes the report.--Includes text from document.
Pollinators-insects, birds, bats, and other animals that carry pollen from the male to the female parts of flowers for plant reproduction-are an essential part of natural and agricultural ecosystems throughout North America. For example, most fruit, vegetable, and seed crops and some crops that provide fiber, drugs, and fuel depend on animals for pollination. This report provides evidence for the decline of some pollinator species in North America, including America's most important managed pollinator, the honey bee, as well as some butterflies, bats, and hummingbirds. For most managed and wild pollinator species, however, population trends have not been assessed because populations have not been monitored over time. In addition, for wild species with demonstrated declines, it is often difficult to determine the causes or consequences of their decline. This report outlines priorities for research and monitoring that are needed to improve information on the status of pollinators and establishes a framework for conservation and restoration of pollinator species and communities.
