Outdoors grade
How much outdoors does Greenland have?
On conserved land, trails, park land and how close residents live to a park, Greenland is ahead of 48% of U.S. towns, #124 of 126 in New Hampshire. Conserved land holds the grade up; park acres per resident pull it down.

New Hampshire towns of 2,500+ (126)Ahead of 2%
New Hampshire towns conserve more land than most (a typical one, 19%; the U.S., 4%), so Greenland’s 22% is ahead of 69% of New Hampshire towns, while its trails per square mile lead 4% of them.
Water is 21% of Greenland’s area (3 of 13 square miles), so every share here is of land; over land and water together, the conserved share would read 18%.
How sure. Graded on any three of the four inputs instead, the letter would range from C to B+. Trails and many small parks come from OpenStreetMap, mapped by volunteers, so coverage varies from town to town; the half mile is a straight line from each census block, so a river or highway in the way isn’t counted against it.

How much of Greenland is conserved land?

Are dogs allowed on Greenland’s trails?
Great Bay National Wildlife Refuge and Great Bay Discovery Center don’t have dog rules recorded on the map; check the signs at the trailhead.
Is there public land near Greenland?
8,121 acres of parks and open public land lie inside Greenland or within 10 miles of it (PAD-US), 12 of them inside the town line.
How much outdoors does Greenland have?
Ahead of 48% of U.S. towns on the Outdoors grade, #124 of 126 in New Hampshire. The grade combines the share of land that is conserved, miles of mapped trail per square mile of land, park acres per 1,000 residents and the share of residents within a half mile of a park. It’s a character grade, so it isn’t part of the overall grade. How it works.
