A NATIONAL STRATEGY TO RESTORE COASTAL AND ESTUARINE HABITAT Dear Friend, The rich interplay between the land and the sea creates one of America’s most valuable natural, economic, and cultural res o u r ces—its estuaries and coasts. In this unique nexus— characterized by the dynamic blending of salt and fresh water during tidal cycles—abundant life is created and nurtu re d . Estuaries nurtu r e not only shellfish, fish, and wildlife, but also nourish the human spirit. We ar e from the sea, and we are continually lured back to its edge, rei n f o r cing the kinship we sh a r e with this place as we sail, fish, swim, and relax near a glistening bay or a rocky shore. And yet, no place on earth more directly embodies the challenge of balancing human needs and the needs of other species than estuaries. By 2025, 75 percent of our population will live within 50 miles of the coast. We must learn how to develop our own habitat while also pro- tecting and restoring the very essence of what binds us to our coasts. Re s t o r e America’s Estuaries and the National Oceanic and Atmospheric Administration are pleased to present A National Strategy to Restore Coastal and Estuarine Habitat, and we are grateful to the scores of scientists, restoration practitioners, program managers, and others who contributed their expertise and insights. This National Strategy takes a major step to w a r d reclaiming losses of the past 200 years. We look forwa r d to continued collaboration as we move forwa r d and reinvest in our coastal and estuarine habitats. Best Regards , Mark Wol f - A rm s t ro n g Scott B.
