The Nature Conservancy works in all 50 states and in over 35 countries around the world to preserve the animals, plants, and natural communities that represent the diversity of life on Earth. They do so by protecting the lands and waters that these species need to survive. The acts performed by the Nature Conservancy contribute immensely to the preservation and protection of temperate deciduous forests.
The Arbor Foundation has grown to become the largest nonprofit membership organization dedicated to planting trees with over one million members, supporters, and valued partners. They work to protect the temperate deciduous forests from dangerous outside forces that could diminish the population of these forests. Their motto is "to inspire people to plant, nurture, and celebrate trees." The Arbor Foundation, because of their kind, hard work, is a huge reason why temperate deciduous forests are still around today.
