2. Description and rationale of the Changes in Wildlife Species Disappearance Risks indicator
The Changes in Wildlife Species Disappearance Risks indicator reports on changes in wildlife species disappearance risks in Canada for species assessed by the Committee on the Status of Endangered Wildlife in Canada (the Committee). The Committee is composed of experts that determine the national status of Canadian wildlife species, subspecies, varieties or other designatable units that are suspected of being at risk of extinction or extirpation. The indicator measures conservation effectiveness and is developed with data provided by the Committee's Secretariat at Environment and Climate Change Canada.
The recognition and assessment of a species as at risk of extinction or extirpation can focus management action towards high-priority issues. Successful management should reduce the risk of species extinction or extirpation. The conservation of species at risk is a key component of the Canadian Biodiversity Strategy, which aims to conserve biological diversity in Canada,Footnote  and is the goal of the Species at Risk Act, which provides legal protection of wildlife species to prevent extinction and secure the necessary actions for their recovery.Footnote 
Ecosystems are composed of a variety of animals, plants and other organisms, each of which performs a specialized role. This diversity of life supports vital ecological processes and provides a wide range of resources known as ecological goods and services, such as oxygen production and water purification.Footnote  The loss of species has detrimental impacts on ecosystems and the goods and services they provide.
