Manicured greenspaces harbor infected ticks


Encountering ticks has typically been thought to occur primarily in wooded, rural areas. But ticks are expanding their geographical range, not only to new areas of the country but from rural to urban greenspaces, as well.

It was once thought that well-kept, manicured yards, for instance, were safe and free of ticks. No longer. As this study finds, ticks can be found even in the most well-groomed recreational spaces.

In their study, “Ticks and Tick-Borne Pathogens in Recreational Greenspaces in North Central Florida, USA,” Bhosale and colleagues examined the potential risk of encountering ticks in recreational greenspaces, particularly in groomed areas.¹

“We hypothesized that the habitat composition within greenspaces, whether it was natural habitat or manicured turf, would impact the abundance of ticks and prevalence of tick-borne disease agents,” they wrote.

Do ticks reside in well-kept, manicured yards and greenspaces?

The authors collected ticks along trails at 17 recreational areas in and near Gainesville, FL. They found 6 tick species which harbored 18 different species of bacteria or protozoa within the Babesia, Borrelia, Cytauxzoon, Cryptoplasma (Allocryptoplasma), Ehrlichia, Hepatozoon, Rickettsia, and Theileria genera.

“While tick abundance and associated microorganism prevalence and richness were the greatest in natural habitats surrounded by forests, we found both ticks and pathogenic microorganisms in manicured groundcover,” the authors wrote.

Encountering an infected tick is “measurable and substantial even on closely manicured turf or gravel, if the surrounding landcover is undeveloped.”

They found that 5 out of the 6 tick species harbored many tick-borne pathogens. Some of these have not yet been described and “could still be of emerging medical or veterinary importance,” the authors point out.

The study found, that “even in manicured turf and landscaping, infected ticks occurred along walking trails and paths, particularly when those manicured habitats were surrounded by moderate amounts of undeveloped landcover.”

The presence of infected ticks in manicured areas suggests the environmental conditions in these spaces is sufficient for ticks to thrive and pose a health risk.

The authors’ conclude:

  • “Overall, the detection of co-infections in our ticks adds to the complexity of the tick pathogen microbiome and suggests the need for continuing research on the importance of co-infections for both human and animal health.”
  • “While we found the highest diversity and abundance of ticks and pathogens in natural habitat within greenspaces, we also found a substantial subset in manicured habitats including turf lawn, picnic areas, or along paved pathways.”

    Ticks appear wherever deer and animals tread. This includes well-manicured yards, golf courses, and even putting greens. Night vision videos show deer, coyotes, and other mammals crossing all greens in addition to fields and woods areas… and these warm-blooded creatures drop ticks, of course. Yards and gardens with watered bird baths also might show high numbers of ticks around the bird baths. Stay alert outdoors.

    Sadly we are not comprehending that ticks are a severe threat and that the Borrelia burgdorferi is not 100% killed by present antibiotics as quoted out by medical doctors to patients suffering the ill effects of this horrible disease. I fear that there are millions of people walking around with Lyme disease or other bacteria, viruses and spores we fail to understand the dangers of. On top of that the cost around the world for medical care because of debilitating effects of lyme and other related issues must negatively effect any medical budgets, not considering the loss of lives or people suffering endlessly.
