New York City's municipal water supply system provides about 1 billion gallons of drinking water a day to over 8.5 million people in New York City and about 1 million people living in nearby Westchester, Putnam, Ulster, and Orange counties. The combined water supply system includes 19 reservoirs and three controlled lakes with a total storage capacity of approximately 580 billion gallons. The city's Watershed Protection Program is intended to maintain and enhance the high quality of these surface water sources. Review of the New York City Watershed Protection Program assesses the efficacy and future of New York City's watershed management activities. The report identifies program areas that may require future change or action, including continued efforts to address turbidity and responding to changes in reservoir water quality as a result of climate change.

Introduction to Forestry and Natural Resources, Second Edition, presents a broad, completely updated overview of the profession of forestry. The book details several key fields within forestry, including forest management, economics, policy, utilization and forestry careers. Chapters deal specifically with forest regions of the world, landowners, forest products, wildlife habitats, tree anatomy and physiology, and forest disturbances and health. These topics are ideal for undergraduate introductory courses and include numerous examples and questions for students to ponder. There is also a section dedicated to forestry careers. Unlike other introductory forestry texts, which focus largely on forest ecology rather than practical forestry concepts, this book encompasses the economic, ecological and social aspects, thus providing a uniquely balanced text. The wide range of experience of the contributing authors equips them especially well to identify missing content from other texts in the area and address topics currently covered in corresponding college courses. - Covers the application of forestry and natural resources around the world with a focus on practical applications and graphical examples - Describes basic techniques for measuring and evaluating forest resources and natural resources, including fundamental terminology and concepts - Includes management policies and their influence at the local, national and international levels

Forest Resource Economics and Finance is intended for undergraduate forestry students, but practicing foresters and policy analysts will also find it a useful reference. The text emphasizes economics as a way of thinking in which we compare added costs and benefits of actions in order to maximize net benefits. With the basics of capital theory, readers learn how to evaluate forestry investments in a way that embraces important environmental factors. Another key feature is a focus on analyzing current conflicts and tradeoffs that will continue to be prominent forestry issues in the 21st century: free market policies versus different levels of government intervention, economic development versus environmental conservation, private property rights versus public amenity rights, and timber versus non-timber outputs. This text also addresses additional topics not often found in other forest economic books including: economics of non-clearcutting management systems, economics of forest damage, risk analysis, inflation, environmental economics, capital budgeting, and regional economics. Add to this a micro-economics review, multiple-use and non-market good analysis, optimal capital management, benefit/cost analysis, timber supply and demand issues, appraisal and valuation, forest industry economics, and world forestry issues, and you have the most comprehensive forest economics text on the market. In addition to new and updated figures throughout the text, this newly-revised second edition provides an overview of important trends in the modern timber industry including advancements in engineered wood, international trade, global environmental issues, as well as community forestry and agroforestry.

An analysis of trees in New York City reveals that this city has about 5.2 million trees with canopies that cover 20.9 percent of the area. The most common tree species are tree of heaven, black cherry, and sweetgum. The urban forest currently stores about 1.35 million tons of carbon valued at $24.9 million. In addition, these trees remove about 42,300 tons of carbon per year ($779,000 per year) and about 2,202 tons of air pollution per year ($10.6 million per year). The structural, or compensatory, value is estimated at $5.2 billion. Information on the structure and functions of the urban forest can be used to improve and augment support for urban forest management programs and to integrate urban forests within plans to improve environmental quality in the New York City area.
