Dog owners and their dogs’ influence on the blue-green algae blooms at Shubie Off-Leash Dog Park, Dartmouth, NS

Abstract

Lake Micmac by Shubie Off-Leah Dog Park in Dartmouth, Nova Scotia has been experiencing blue-green algae blooms, a cyanobacteria that can be harmful to the environment and the health of animals, including humans. As blue-green algae blooms occur more frequently, recreational areas including Shubie-off Leash Dog Park are at risk of being closed to the public. A study looking at the sources of fecal contamination in Lake Micmac found that there was a high amount of canine fecal markers nearshore of the Shubie Off-Leash beach. Considering fecal matter contains algae-inducing nutrients, it is suspected that unattended dog waste is contributing to the increasing frequency of blue-green algae blooms in Lake Micmac. Through unobtrusive dog observations and an in-person survey, this study investigates how dog owners manage their dog waste at Shubie Off-Leash Dog Park. Findings suggest there are an insufficient number of amenities including trash bins, doggie bags, and signs stating what areas are designated as on or off-leash. Signage that is present is confusing to some. Other results revealed many dog owners disliked other dog owners and their dogs. Therefore, it is recommended that the park management look into more amenities related to facilitating proper dog waste disposal. Signage should be clear to understand, appealing, and located in popular areas such as trails and trailheads. Engaging with dog owners is needed to form collective community norms that comply with park policy. Park management should also explore fencing certain areas that are naturally ill-defined without affecting the park user’s experience. Finally, future studies need to seek out how effective educational measures like the “Canine for Clean Water Campaign” are at informing the public.
