Vermont designated one of “America’s most endangered places.” Rate of development is 2.5 times rate of population growth. 1997 - 2007, 75 square miles were developed in VT (7X the area of Burlington). Vermonters for a Sustainable Population Losing Habitat

81% of Land in Vermont is Privately Owned Privately Held Land in Vermont Private Public
Auto Dependent Employment • 625,741 people in VT • 67.9% or 424,899 Vermonters are in the workforce • Of the working Vermonters 75% or 318,600 drive alone • Most drive 10 – 25 miles each way
Population and Housing Trends By 2030, Vermont’s population is expected to increase by 14% with and additional 86,000 residents. Development Outpaces Population Since 2000, there have been approximately 1,400 new households annually. U.S. Census, 2010. Vermont Housing Finance Agency, 2009. Transition Vermont, 2009
Outdoor recreation supports 35,000 jobs $4.1 million from hunting, fishing and wildlife watching $187 million annually in state tax revenue $2.5 billion annually in retail sales and services Economic Contributions
Biological Diversity in Vermont • There are between 24,000 – 43,000 species in Vermont. • Most species we know little about Vermont Biodiversity Project
Loss of Wetlands Fragmentation hurts ecological function
Invasive Species on the Rise • 2/3 of VT’s trees are at risk to 3 invasive tree pests • Non-native plants are outcompeting native ones, reducing biodiversity • Water quality and recreation are impacted by aquatic invasives
Pollution Phosphorus Concentrations in Lake Champlain affects water quality, recreation, transportation and aesthetics
Changes in Precipitation Map: Progress Report of the Interagency Climate Change Adaptation Task Force: Recommended Actions in Support of a National Climate Change Adaptation Strategy, October 5, 2010.
Climate Change Forecasts • Current: Temperatures have increased 1.8°F since 1970, with winter rising faster. • Projected: Average temperatures are projected to rise 9°F to 13° F in winter by late-century. • Current: Precipitation has increased 15-20% over the past 50 years with 67% of this falling in heavy precipitation events. • Projected: Winter precipitation will increase on the order of 20-30% with less snow - more rain. • Projected: Short-term summer droughts are projected to occur 2x as often From Union of Concerned Scientists – Confronting Climate Change in the Northeast (NECIA 2007)
Changing Climate Trends • More frequent hot (over 90), humid days • Longer growing seasons • Worsening of air quality in areas where problems already exist • Increased heavy downpours • More frequent winter thaws and earlier springs • Less winter precipitation falling as snow and more as rain • Earlier spring snowmelt resulting in earlier peak river flows • More frequent short-term droughts in late summer and fall
Ecosystem resiliency A Resilient Landscape has space for dynamic natural processes Connect areas of physical landscape diversity for climate change adaptation
Habitat Blocks Areas of natural cover surrounded by roads, development and agriculture • Interior forest habitat and intact ecological processes
