The IUCN Red List is a critical indicator of the health of the world's biodiversity. Far more than a list of species and their status, it is a powerful tool to inform and catalyze action for biodiversity conservation and policy change, critical to protecting the natural resources we need to survive. It provides information about range, population size, habitat and ecology, use and/or trade, threats, and conservation actions that will help inform necessary conservation decisions.

OBS

... encompasses coastal wetlands, major rivers and adjacent uplands of British Columbia, Washington, Oregon and Northern California. It is one of several critical habitat areas identified in the North American Waterfowl Management Plan. This plan created in 1986 by the United States and Canada and joined in 1988 by Mexico, is a partnership of local citizens, private companies, conservation organizations, and government agencies. A primary goal of the plan is to reserve the downward trend in waterfowl populations by returning their numbers to those recorded in the 1970s. In order to achieve this goal, the plan works to secure, restore or enhance priority wetlands and maintain some of the current wetland uses to which waterfowl have adapted, such as farming and ranching.

OBS

In recognition of the importance of protecting our natural heritage, the Government of Canada will commit $90 million over three years and, in subsequent years, will stabilize funding at $45 million annually to create a National Strategy on Species at Risk. Under this strategy, the Government will introduce federal species protection legislation and stewardship programs, which will build on the work done with provincial and territorial partners under the Accord for the Protection of Species at Risk. This national strategy will protect species at risk and their critical habitat by funding recovery initiatives and species protection activities.

OBS

Conscient de l'importance de la protection du patrimoine naturel canadien, le gouvernement engagera une somme de 90 millions de dollars au cours des trois prochaines années et, par la suite, il stabilisera ce financement à 45 millions de dollars par an pour créer une Stratégie nationale concernant les espèces en péril. Dans le cadre de cette stratégie, le gouvernement adoptera des mesures législatives fédérales visant à protéger les espèces en péril et des programmes de gérance, faisant fond sur les travaux effectués avec ses partenaires provinciaux et territoriaux en vertu de l'Accord pour la protection des espèces en péril. Cette stratégie nationale permettra de protéger les espèces en péril et leur habitat essentiel en finançant des initiatives de rétablissement et des activités de protection des espèces.

Subject field(s)
  • Air Pollution
CONT

While much emphasis has been placed on reducing sulphur dioxide emissions, NOx emissions must also viewed with concern due to their contribution to the pH depression associated with the snowpack melt episodes. This depression, when imposed on the surface waters where the acidity has already been increased due to excess sulphates, results in levels of acidity that may be critical and occur at sensitive life stages of many aquatic organisms, even though the long-term average acidity may be tolerated by a normal biological habitat.
