We are people who care about – and for – forests. American Forests, the oldest national nonprofit conservation organization in the country, advocates for the protection and expansion of America’s forests. Since 1990, we have planted nearly 40 million trees. We restore watersheds to help provide clean drinking water. We replant forests destroyed by human action and by natural disasters. Our work is guided by science: choosing the right mix of trees for particular locations, the best trees to act as windbreaks or to filter water, the trees that will provide wildlife habitat, or are most suitable for city streets and parks. Our advocacy is also guided by science: keeping policymakers informed about how trees interact with climate, sequester carbon, manage water, and benefit cities. We explain that ecological services from trees and forests have real economic value. We work in and advocate for federal, state, and urban forests, and sometimes our work takes us beyond US borders. Our hundreds of diverse projects have included: (a) Planting jack pine trees in Michigan’s Huron-Manistee National Forest to restore summer habitat for the endangered Kirtland’s warbler. (b) Restoring Cuyamaca Rancho State Park near San Diego after 95 percent of it was destroyed in a 2003 fire so hot that it killed the seeds that would have allowed the forest to regrow naturally. (c) Planting ponderosa pines and Douglas firs to help Colorado recover after a 2002 fire known as the Hayman Burn destroyed over 135,000 acres, including 8,000 acres surrounding the Chessman Reservoir, which supplies water to Denver. (d) Planting native trees in Michoacán, Mexico, to provide winter habitat for migrating monarch butterflies. ... [Information of the supplier]
