This represents the total number of 750-m transects sampled at each park. Most sites had three transects sampled two times (N =6).
Transects from which extra sampling in surrounding suitable habitat was conducted in effort to obtain ≥50 nymphal I. scapularis for B. burgdorferi infection prevalence estimates; extra ticks collected off transect were not included in density estimates.
One Rhipicephalus sanguineus male and one Haemaphysalis leporispalustris nymph caught in 2015.
Transects 1 and 2 at Monocacy National Battlefield were only sampled a single time in 2015.
One A. maculatum male caught in 2014.
