In parts of Washington, almost all of the landscape has been altered. As eastern Washington's population is growing, its natural landscape is rapidly disappearing. Through Natural Area Preserves the Department of Natural Resources (DNR) protects remnants of Washington's natural heritage, reconstructs habitat and contributes to a healthy environment for future generations. Natural Area Preserves are set aside for research and provide opportunities for education. Many require a DNR guide, but others have interpretive trails where anyone can learn about Washington's unique natural heritage on their own.<ref>''Department of Natural Resources'', Southeast Region office at (509) 952-8510.</ref> | In parts of Washington, almost all of the landscape has been altered.
