Explore the management options and challenges in protecting water resources in the Catskill Mountains of New York. Learn about the connection between forests and water and the importance of diversifying forest structure for resilience. Discover the efforts of the Massachusetts DCR-Division of Water Supply Protection in managing the Boston water supply.

Overview • Management options • From the forest to the faucet in Boston • What’s wrong with this forest? • Silviculture to enhance watershed forests • Deer and regeneration • The connections between forests and water • Questions
Management Options • 1. Business as usual • timber production with conservative BMPs [CMPs] • 2. Watershed Forest Management • changing forest structure to enhance vigor and diversity • resistance to and resilience following natural disturbance • water …first, other products and values …second • 3. Do nothing …designate as a ”wilderness” area
Boston’s Water Supply • Boston and 40 communities; 2,500,000 people • Unfiltered supply • DWSP Mandate: …pure water for future generations • Deliver ≥ 250,000,000 gallons/day …in perpetuity • 100,000 acres ~$1 million stumpage, $100 million water The critical first barrier
The Protection Forest: What’s wrong with this picture? • What’s right? Forest…all other land covers degrade water. • But, mature, even-aged overstory • Capacity for nutrient uptake by older forests is limited • Susceptibility to catastrophic wind (‘38 data – 50-70% damage) • lower resistance • Underdeveloped understory and midstory • Slower recovery from disturbance • Lower nutrient assimilation • lower resilience

Not just young, aggrading forests everywhere… Multiple age classes/layers (The conversion of even-aged stands to uneven-aged structure in Southern NE (Kelty et al. 2003 NJAF)) • Overstory (maturing) • regulates microclimate • seed source • large woody debris • Midstory (aggrading) • assimilates nutrients • accumulates biomass • resistant to wind damage • Regeneration (ready reserve) • least susceptible to disturbance

Regeneration (shoot the deer!) • No hunting access (1936 – 1990) • Controlled hunt (1991 – present)
Div. of Water Supply Protection Forest Management • 80,000 acres under management • 8 field foresters • 8-10 MMBF/year sawtimber, 4,500 cords fuelwood, and 7,000 tons of pulpwood • Stumpage ~$1 million • First public land in North America to be Green Certified

Sustainable forestry is [still] the antidote to exploitive logging. Gifford Pinchot, 1903 …”A Primer of Forestry “A forest, large or small, may render its service in many ways. It may reach its highest usefulness by standing as a safeguard against floods, winds, snow slides, moving sands, or especially against the dearth of water in streams.” Raphael Zon, 1911 …”Forests and Water in Light of Scientific Investigation “A national policy which, though considering the direct value of forests as a source of timber, fails to take full account also of their influence upon erosion, the flow of streams, and climate, may easily endanger the well-being of the whole people.”

Policy Statement National Association of State Foresters Jackson, Mississippi September 29, 2004 (last Wednesday) “The Connection Between Forests and Water” “Water, in all its uses and permutations, is by far the most valuable commodity that comes from the forest land that we manage, assist others to manage, and/or regulate.”
