Status of New Hampshire’s Conservation Lands

SB 388 and beyond

April 2015

Purpose of the SB 388 Study Committee

Current composition of conservation lands: • Acreage & percentage resource protection • Geographic distribution • Entities holding lands

Identify strengths and weaknesses of current portfolio (public and private) in relation to:

• Drinking water supplies • Land base for farming and forestry • Protection fish and wildlife habitat • Providing outdoor recreation opportunities

Methodology & Data Sources

Study Methods: • Best available natural resource GIS datasets • Statewide scope & scale • Augmented GRANIT conservation lands datalayer

Key datasets: • Habitat – Wildlife Action Plan, Natural Heritage EOs, large forest blocks • Wetlands – USFWS National Wetlands Inventory & hydric soils data • Land Cover – USGS national land cover data set, updated every ~5 years • Farm Soils – lands with prime, statewide important agricultural soils • Drinking water – source water protection areas, wellhead protection

areas, aquifers • Forestry – productive forest soils

What is Protected Land?

Permanently Protected: • Permanently protected by legal means • Cannot be developed • Remains in a largely natural status • Agricultural & forestry uses permitted except on ecologically

significant lands

Current Status of GRANIT data: • 4% of database is not legally protected, but has mandates to

manage for natural land cover (e.g., Dartmouth’s Second College Grant

• 1% is unprotected but 50% or more land in natural condition • Another 5% is of unknown status

The big picture…

Our State 32% protected (1.85M acres)

How are we doing protecting land that is important for water?

Source water 7% land area 45% protected 7% developed

Community wells 5% land area 16% protected 19% developed

13.5% land area 25% protected

28% land area 30% protected 12% developed

Farms and forests…

Most productive soils <7% land area 12% protected 20% developed

Active farmland <4% land area 13% protected

2/3 of statewide land cover 42% protected

500 – 5,000 acre blocks 25% of all forest blocks 18% conserved

Forest Blocks >5,000 acres

Forest Blocks >10,000 acres

2.3 million acres 57% protected

1.9 million acres 63% protected

Our wildlife and natural heritage…

Significant Wildlife Habitat 40% of high-ranked habitat protected 52% of Tier 1 protected

Rare Species Occurrences More than 4,000 occurrences 37% protected

Recreation opportunities…

Convenient Accessibility Municipalities >10,000 20 minute drive (10 mile radius 54% of total state population 20% of conserved land

Municipalities >20,000 10% of conserved land

Regional & Local Trails 2,700 miles mapped 82% on conserved land Regional systems = 150 miles 52% protected All long distance trails = 443 miles 30% protected

Next steps with SB 388

Committee recommendations included: • Fully fund LCHIP and constitutionally protect

dedicated funds • State funding of existing

programs: Agricultural land program (ALP) and Source Water protection fund

• Create Legislative Commission to develop NH priorities for future state investments in land conservation (SB38)
