Seasonal Dynamics of Tick Species in the Ecotone of Parks and Recreational Areas in Middlesex County (New Jersey, USA).

People often use parks and other forested areas for outdoor activities such as hiking and walking their dogs. Areas of primary use are paths or grassy meadows on the edges of the forests that constitute transitional areas between different plant communities (aka ecotones). In this study, we monitored the seasonal dynamics of questing ticks in forest/meadow and forest/path ecotones in five areas in Middlesex County, New Jersey (NJ). We found anthropophilic species such as , , and coexisting with , an invasive tick species first detected in NJ in 2017. Surveillance was conducted weekly from March to November 2020, and collected ticks were identified. The most abundant tick species was (83%), followed by (9%), (7%), and (<1%). The seasonal dynamics of and in the ecotone were similar to previous surveys in forest habitats. The presence of anthropophilic ticks, particularly , suggests the need for specific control approaches to target these habitats. In addition, the extraordinarily high numbers of collected in ecotones (1.70 ticks/m) and frequent reports of this species on dogs highlight the importance of monitoring its expansion due to its potential as a vector of animal and human diseases.
