  • Estimating trail use and visitor spatial distribution using mobile device data: An example from the nature reserve of Orange County, California USA

    Megan Lawson, Ph.D.

    This study uses mobile data from the analysis platform Streetlight to estimate visitor use in four urban parks and protected areas in Orange County, California. The mobile device methods are compared to other trail counting methods to determine whether mobile device data could be a reliable measure of trailhead visitation counts and spatial distribution of… Read more

  • Equity in Access to Outdoor Recreation – Informing a Sustainable Future.

    Megan Lawson, Ph.D.

    Residents in four large metropolitan areas in California were interviewed by phone to determine differences in outdoor recreation participation in national forests by ethnoracial groups, age, and gender. The researchers found that the most listed constraint to participation among all groups was a lack of time, though minority respondents were more likely to list resource-related… Read more

  • Planning for Environmental Justice in an Urban National Park

    Megan Lawson, Ph.D.

    The authors conducted a survey in Santa Monica Mountains National Recreation Area in Los Angeles to understand park accessibility and how socio-demographic characteristics affect individuals’ use of the park. They found that the average park user is white, male, middle-aged, has a college education, earns between $50,000-$75,000 per annum, and was born in the United… Read more

  • Association Between User-Generated Commuting Data and Population-Representative Active Commuting Surveillance Data—Four Cities, 2014-2015

    Megan Lawson, Ph.D.

    One of the primary concerns about data from GPS tracking apps is that the users tend to be more frequent recreators or commuters and therefore do not accurately represent the actual population. This paper shows that there is a strong correlation between the reported share of people in a neighborhood commuting by active transportation between… Read more

  • Parks and Park Funding in Los Angeles: An Equity-Mapping Analysis

    Megan Lawson, Ph.D.

    In Los Angeles, historic land use policies that emphasized low-density housing and did not prioritize public park spaces have led to significant inequities of park access across race, ethnicity, and income. A fund designed to improve access to public parks could exacerbate this problem unless it considers proposals for nontraditional public spaces such as schoolyards… Read more

  • Childhood Obesity and Proximity to Urban Parks and Recreational Resources: A Longitudinal Cohort Study

    Megan Lawson, Ph.D.

    By following a large sample of children over time, this study demonstrates that children who participate in recreation programs, or who live a walkable distance from parks, are much less likely to be obese or overweight. These benefits can be achieved through formal parks and programs, but also through accessible green space or other small,… Read more

  • Neighborhood Income Matters: Disparities in Community Recreation Facilities, Amenities, and Programs

    Megan Lawson, Ph.D.

    At a sample of recreation centers in southern California, researchers find that several measures of facility condition and amenities are better in high-income neighborhoods relative to low-income neighborhoods. The likelihood that a child uses the recreation center increases 23 percent for each $10,000 increase in neighborhood income, but the authors do not find a relationship… Read more

  • Neighborhood Poverty, Park Use, and Park-Based Physical Activity in a Southern California City

    Megan Lawson, Ph.D.

    A large study of 50 urban parks in Southern California measures park use by nearby residents and other users across high-, medium-, and low-poverty areas, finding that parks are used less in high-poverty areas. Those who do use parks in high-poverty areas, however, on average use the parks more per week, are more likely to… Read more

  • Economic Benefits of Mountain Bike Tourism for Santa Cruz County

    Megan Lawson, Ph.D.

    This report on the potential for mountain bike tourism in Santa Cruz County, California demonstrates how trail advocates can use existing research studies to help make a case for trail development in their community. The authors argue that the presence of significant bike industry companies, a large existing social trail network, and appealing climate and… Read more

  • Outdoor Recreation Net Benefits of Rail-Trails

    Megan Lawson, Ph.D.

    This study found that trail users are willing to incur greater expenses and travel further to use rural trails, and spend more time on those trails while they are there, indicating these trails are enjoyed by both locals and non-locals. Urban trails, on the other hand, are mainly a resource for local residents, and are… Read more
