Local tick habitat
Mercersburg Borough is 70% natural land cover (42% forest, plus open and brushy areas) across its 0.9 sq mi, home to about 1,496 people. That makes it the 7th-most wooded of the 22 towns in Franklin County. Deer ticks live in wooded areas, along trail edges, and in tall grass: the more of that a town has, the more places ticks can quest.
Franklin County reports about 70 Lyme cases per 100,000 people a year, in the top 12% of U.S. counties for reported Lyme disease. That county-level disease pressure, combined with Mercersburg Borough's local habitat, sets how high its daily score can climb when the weather and season allow.
