Abstract
Mundy Park is a popular and well-loved urban green space, ranked as the #1 activity in Coquitlam on TripAdvisor (TripAdvisor 2026). In the western portion of the park, a shallow pond surrounded by the disc golf course and forested edges supports active populations of amphibians, including Pacific chorus frog (Pseudacris regilla), a recognized indicator of urban biodiversity. In our field surveys on October 6 and 10, 2025, we recorded 11 auditory Pacific chorus frog detections at the Pond – confirming their active presence at a site that has received little dedicated ecological attention in the park's planning history. Other native amphibians identified in the park include Ensatina (Ensatina eschscholtzii) and Long-toed salamander (Ambystoma macrodactylum), as well as the invasive American bullfrog (Lithobates catesbeianus). The Pond and its surrounding habitat face invasive vegetation encroachment – particularly Yellow flag iris (Iris pseudacorus) – soil compaction, bank erosion, and unsanctioned trail networks resulting from frequent recreational use of the western park edge. A warming and drying climate poses further risk, as Pacific chorus frogs and other species reliant on ephemeral ponds are particularly sensitive to drought. Previous environmental planning documents have focused primarily on Mundy Lake and the park's eastern forest, leaving the western edge and its amphibian community largely unaddressed. We propose a targeted and achievable restoration plan anchored in community stewardship and support from the City of Coquitlam to fill this gap. In this plan we focus on amphibian habitat enhancement and public engagement at the Pond through invasive plant removal, native vegetation planting, water quality treatment, physical habitat protection through fencing, interpretive signage, and collaboration with existing community stewardship programs such as Tree Spree and Park Spark (City of Coquitlam 2026). These recommendations are designed to be implemented and sustained by the City of Coquitlam and local stakeholders, making the community not just a beneficiary of restoration, but its primary agent. The total cost of our proposed activities is $62,494.38 over three years, with two to three years of monitoring and maintenance (Tables 5-7).
