These same species are important environmental indicators. Their populations reflect the health and diversity of the environment. Alberta Sustainable Resource Development The preparation and distribution of this report is has designated as one of its core business designed to achieve four objectives: goals the promotion of fish and wildlife conservation. The status of wild species is 1. To provide information on, and raise one of the performance measures against awareness of, the current status of wild which the department determines the species in Alberta; effectiveness of its policies and service 2. To stimulate broad public input in more delivery. clearly defining the status of individual Central to achieving this goal is the accurate species; determination of the general status of wild 3.
