Title: Integrating tick density and park visitor behaviors to assess the risk of tick exposure in urban parks on Staten Island, New York
Abstract Background Public green spaces are important for human health, but they may expose visitors to ticks and tick-borne pathogens. We sought to understand, for the first time, visitors’ exposure risk and drivers of tick-preventative behavior in three popular parks on Staten Island, New York City, NY, USA, by integrating tick hazard and park visitors’ behaviors, risk perceptions and knowledge. Methods We conducted tick sampling in three parks, across three site types (open spaces, the edge of open spaces, and trails) and three within-park habitats (maintained grass, unmaintained herbaceous, and leaf litter) to estimate tick density during May-August 2019. Human behavior was assessed by observations of time spent and activity type in each site. We integrated the time spent in each location by park visitors and the tick density to estimate the probability of human-tick encounter. To assess visitors’ tick prevention behaviors, a knowledge, attitude, and practices (KAP) survey was administered. Results Three tick species ( Ixodes scapularis , Amblyomma americanum and Haemaphysalis longicornis) were collected. For all species, the density of nymphs was greatest in unmaintained herbaceous habitats and trails, however, the fewest people entered these hazardous locations. The KAP survey revealed that most respondents ( N  = 190) identified parks as the main location for tick exposure, but most believed they had minimal risk for tick encounter. Consequently, many visitors did not conduct tick checks. People were most likely to practice tick checks if they knew multiple prevention methods and perceived a high likelihood of tick encounter. Conclusions By integrating acarological indices with park visitor behaviors, we found a mismatch between areas with higher tick densities and areas more frequently used by park visitors. However, this exposure risk varied among demographic groups, the type of activities and parks, with a higher probability of human-tick encounters in trails compared to open spaces. Furthermore, we showed that people’s KAP did not change across parks even if parks represented different exposure risks. Our research is a first step towards identifying visitor risk, attitudes, and practices that could be targeted by optimized messaging strategies for tick bite prevention among park visitors.  more » « less

    Societal Impact Statement Summary

    Urban parks provide numerous cultural and ecological benefits, but may not always meet diverse visitor preferences. There is a need for additional on‐site research, which has the potential to gauge vegetation preferences in a more authentic and multi‐sensory context. We asked: how does vegetation in urban parks currently meet visitor preferences?

    We performed on‐site semi‐structured interviews with visitors at 15 different parks of three general types (i.e., natural‐passive use, recreational‐active use, and multi‐use parks), using a case study of Portland, Oregon, a mid‐sized city in North America with a temperate climate. We transcribed the interviews and coded them for themes and patterns of meaning.

    Visitors across demographics groups discussed trees, size, and diversity/variety as some of their favorite aspects of the vegetation. Trees were important for visitors, particularly for their large size/shade, but vegetation preferences tended to vary across park type and slightly more than half of participants suggested changes. Many recreational‐active and multi‐use park visitors desired more flowers, color, grass, middle growth, trees, and food‐bearing plants, as well as improved placement, while visitors to natural‐passive use parks preferred additional invasive/harmful plant removal.

    Integrating visitor vegetation preferences into plant selection, layout, and maintenance has the potential to increase ecosystem services of urban parks. The incorporation of colorful, native flowers for visitors can also provide habitat for native species. Visitors across park types also desired to learn more about plants, and so additional interpretive signs/labels and multi‐sensory gardens can help to engage and educate visitors.

    Green spaces are beneficial for physical and mental health, especially during and after disasters. The COVID-19 pandemic, however, created a trade-off: parks could be therapeutic but also could expose people to infection. This paradox posed inequities as marginalized populations often have less access to parks and were hit harder by the pandemic. We combined cellphone-generated mobility data with demographic indicators, a neighborhood survey, and local infection rates to examine how residents of Boston, MA, navigated this trade-off in April–August 2020. We hypothesized that they adopted strategies for mitigating infection exposure—including fewer park visits and prioritizing parks that might have lower infection risk, including larger parks with more opportunity for social distancing and parks near home with fewer unfamiliar faces—but that marginalized populations would have less opportunity to do so. We also introduce a novel measure of exposure per visit based on the volume of other visitors, infection rates, and park size. Bostonians made fewer park visits relative to 2019 and prioritized larger parks and parks closer to home. These strategies varied by community. Experiences of the pandemic were influential, as communities that perceived greater risk or had more infections made more park visits, likely because they were a relatively safe activity. Communities with more infections tended to avoid nearby parks. Inequities were also apparent. Communities with more Black residents and infections had greater infection exposure per visit even when controlling for the types of parks visited, highlighting difficulties in escaping the challenges of the pandemic.

    Abstract Background The incidence of tick-borne disease has increased dramatically in recent decades, with urban areas increasingly recognized as high-risk environments for exposure to infected ticks. Green spaces may play a key role in facilitating the invasion of ticks, hosts and pathogens into residential areas, particularly where they connect residential yards with larger natural areas (e.g. parks). However, the factors mediating tick distribution across heterogeneous urban landscapes remain poorly characterized. Methods Using generalized linear models in a multimodel inference framework, we determined the residential yard- and local landscape-level features associated with the presence of three tick species of current and growing public health importance in residential yards across Staten Island, a borough of New York City, in the state of New York, USA. Results The amount and configuration of canopy cover immediately surrounding residential yards was found to strongly predict the presence of Ixodes scapularis and Amblyomma americanum , but not that of Haemaphysalis longicornis . Within yards, we found a protective effect of fencing against I. scapularis and A. americanum, but not against H. longicornis . For all species, the presence of log and brush piles strongly increased the odds of finding ticks in yards. Conclusions The results highlight a considerable risk of tick exposure in residential yards in Staten Island and identify both yard- and landscape-level features associated with their distribution. In particular, the significance of log and brush piles for all three species supports recommendations for yard management as a means of reducing contact with ticks. Graphical Abstract

    Abstract The incidence of tick-borne diseases has increased in recent decades and accounts for the majority of vector-borne disease cases in temperate areas of Europe, North America, and Asia. This emergence has been attributed to multiple and interactive drivers including changes in climate, land use, abundance of key hosts, and people’s behaviors affecting the probability of human exposure to infected ticks. In this forum paper, we focus on how land use changes have shaped the eco-epidemiology of Ixodes scapularis-borne pathogens, in particular the Lyme disease spirochete Borrelia burgdorferi sensu stricto in the eastern United States. We use this as a model system, addressing other tick-borne disease systems as needed to illustrate patterns or processes. We first examine how land use interacts with abiotic conditions (microclimate) and biotic factors (e.g., host community composition) to influence the enzootic hazard, measured as the density of host-seeking I. scapularis nymphs infected with B. burgdorferi s.s. We then review the evidence of how specific landscape configuration, in particular forest fragmentation, influences the enzootic hazard and disease risk across spatial scales and urbanization levels. We emphasize the need for a dynamic understanding of landscapes based on tick and pathogen host movement and habitat use in relation to human resource provisioning. We propose a coupled natural-human systems framework for tick-borne diseases that accounts for the multiple interactions, nonlinearities and feedbacks in the system and conclude with a call for standardization of methodology and terminology to help integrate studies conducted at multiple scales.

    Metropolitan Phoenix, Arizona, in the Sonoran Desert, provides an excellent opportunity to understand residents’ preferences for desert-adapted xeric landscaping. While much is known about the relationships between sociodemographics and broad environmental values on xeric landscaping choices, the influence of other variables remains unexplored, especially interactions with and attachments to the desert. We therefore examined the influences of recreational visits to local desert mountain parks and symbolic meanings associated with the native desert on household xeric landscaping preferences. Within a larger study, select questions captured socio-demographics, visitation to desert parks and open spaces, place identity, and xeric landscape preferences. Using Ordinary Least Squares (OLS) regression, we confirmed that homeownership and a shorter residency predicted preference for xeric landscapes. Hispanics were less likely to prefer xeric landscaping. Interestingly, the novel factor of identity with the desert significantly and positively predicted xeric landscaping preference while visitation to desert parks and open spaces did not. Findings provide several important management implications. First, Phoenix has an opportunity to foster connections with the surrounding environment through its extensive desert mountain parks. Increasing connections between residents and the parks may help shift personal preferences to xeric yard types. Park managers might also work to further stress how household decisions can affect the desert environment. Second, park visitation alone may not suffice to create connections with the desert environment. Instead, park managers should focus on creating opportunities for visitors to recognize the unique, living aspects of the parks and build personal relationships with the ecosystem. Interpretation encouraging emotional connections to the desert environment may aid in fostering an identity with the desert. In addition, messaging and signage campaigns that link people to the parks may prove a novel way of combatting lawn water usage within desert cities. Given their opportunities to foster place identity, urban parks may be important influencers in promoting native plant landscaping. In conclusion, connecting people to their surrounding environments can influence preferences for similar landscape types at the household level.
