Updated map of blacklegged tick distribution

Rebecca Eisen and colleagues from the CDC have updated the well-known Dennis et al. (1994) black-legged tick distribution map.  Data for counties in several states, particularly Tennessee and Michigan, were contributed by the Lyme Gradient  team.

The distribution of tick sightings across the United States between a) 1907–1996 and b) 1907–2015  (D. T. Dennis et al., J. Med. Entomol. 1998; R. J. Eisen et al., J. Med. Entomol. 2016).
A ScienceMag story on the map includes a nice shout-out to Isis, for her PhD studies comparing the questing behavior of Northern and Southern ticks.
