Local tick habitat
Trenton is 37% natural land cover (32% forest, plus open and brushy areas) across its 7.61 sq mi, home to about 89,620 people. That makes it the 12th-most wooded of the 12 towns in Mercer 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.
Mercer County reports about 91 Lyme cases per 100,000 people a year, the 150th-highest of 210 Northeast counties. That county-level disease pressure, combined with Trenton's local habitat, sets how high its daily score can climb when the weather and season allow.
