LessMore
New Jersey towns conserve more land than most (a typical one, 11%; the U.S., 4%), so Mannington Township’s 48% is ahead of 96% of New Jersey towns, while its trails per square mile lead 7% of them.
Water is 11% of Mannington Township’s area (4 of 38 square miles), so every share here is of land; over land and water together, the conserved share would read 43%.
How sure. Graded on any three of the four inputs instead, the letter would range from B− to A. 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.
