How we measure
"Trails" are OpenStreetMap paths, bridleways, public tracks and unpaved footways, plus footways inside a park or preserve or on a named trail route. Sidewalks are left out. Areas are counted on a 20-meter grid, so overlapping parcels count once. "Conserved" includes conservation easements, which protect land from development but are usually private property. Trailheads are the nearest marked trailhead, public parking lot or information board within about 150 meters of a preserve. Dog rules come from OpenStreetMap when someone has tagged them; otherwise we show what's typical for the land manager, or say the rules aren't recorded.
