The tri-state region includes hundreds of iconic parks and landscapes, from the forested open spaces of the Catskills, Highlands, and Pinelands to the sandy shores of New Jersey and Long Island. But these spaces are largely disconnected from each other and from the population centers that use them. Linking these areas of precious natural beauty would boost recreational opportunities, catalyze economic development, and enhance the biodiversity of our natural systems, leading to better health and quality of life for our residents. Federal, state, and local government should collaborate with land trusts, trails groups, and other partnerships to develop an integrated network of biking, hiking, and walking trails from underutilized rights-of-way such as roadways, rail lines, transmission lines, and pipelines.
