The Ecoregion

 

 

(tree) No longer protected by climate and distance, the frozen reaches of the continent pose an icy challenge to environmentalists worldwide.

A Wild and Unbounded Place

(tree) The Sierra Club's Critical Ecoregions Program offers a practical, long-term strategy to buttress the "web of life" on Earth. Region by region, we're developing multifaceted plans for every major land and water system in the United States and Canada, home to most of the Sierra Club's 500,000 members. Tailored to the particular needs of each ecosystem, these 21 regional plans will help achieve our global vision--to restore the ecological health of the planet--through concrete local action.
