How much outdoors does Petersham have?
On conserved land, trails, park land and how close residents live to a park, Petersham is ahead of 97% of U.S. towns. All four inputs are above most U.S. towns; conserved land ranks highest, the share of residents near a park lowest.
Massachusetts towns conserve more land than most (a typical one, 21%; the U.S., 4%), so Petersham’s 77% is ahead of 100% of Massachusetts towns, while its trails per square mile lead 27% of them.
Water is 21% of Petersham’s area (14 of 68 square miles), so every share here is of land; over land and water together, the conserved share would read 62%.
