Aesthetic Values

People of diverse cultures appreciate and observe wildlife. With the increase in the importance of economic, social, and aesthetic, values of wildlife comes the responsibility for wise management and use of these resources to ensure biodiversity and the continued wellbeing of the populations. We describe several ways in which ecotourists affect the behaviour, reproductive success, and population levels, of breeding and migratory birds in New Jersey — a heavily industrialized, coastal US state with a dense human population. We use several case-studies to illustrate the effects of ecotourists on birds: heronries, breeding Least Terns (Sterna antillarum), foraging Piping Plovers (Charadrius melodus) during the breeding season, migrant shorebirds and gulls at Caven Point and Delaware Bay, and migrant hawks at Cape May.

Abstract Disturbance from human activity can cause reduced productivity of coastal birds that nest on sandy beaches. A common method to protect coastal birds from human disturbance is the use of signs and fencing to close off a section of beach used for breeding. This management action requires public compliance and might require enforcement, such as in the use of volunteer stewards stationed at protected colonies that provide education and enforcement. I assessed the effectiveness of active stewardship as a conservation measure to protect nesting Least Terns (Sternula antillarum) in coastal Mississippi by determining if colony-level productivity (fledglings produced per nest) was correlated with stewardship effort (hours that stewards protected each colony), the rate of disturbance from human and natural sources, and additional factors. Observers surveyed 24 Least Tern colonies in Harrison County, Mississippi, twice weekly during the 2017–2019 breeding seasons to record the number of nests present, the fate of marked nests, predator tracks within the colony, and the number of fledglings produced per colony. Concurrently, during their work shifts, stewards recorded all sources and durations of disturbance events that caused the terns to flush or respond with defense. Least Tern daily nest survival increased with colony size and stewardship effort, and was lower during intervals that included weekends and evidence of owl presence. Total productivity was negatively associated with avian predator disturbance rate and the total time adults spent flushed, but was not associated with stewardship effort. The results of this study demonstrate that active stewardship can have a positive effect on Least Tern productivity by increasing nest success, whereas current stewardship practices were not sufficient to increase chick survival, even in a system with a paucity of ground predators.
