New Hampshire towns conserve more land than most (a typical one, 19%; the U.S., 4%), so Greenville’s 9% is ahead of 10% of New Hampshire towns, while its trails per square mile lead 1% of them.
How sure. Graded on any three of the four inputs instead, the letter would range from B− 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.
