Join the TTC team, local experts, and community members to identify and record the biodiversity of Holly Shores as a part of the City Nature Challenge 2026.
A bioblitz is an event that brings experts and community members together to create a comprehensive list of an area’s existing biodiversity. During the event, participants will try to observe and report as many species as possible in a specific location, working with local experts to ID the species they see and iNaturalist.
The data collected at the Holly Shores BioBlitz will assist The Trail Conservancy in conducting restoration projects in the area moving forward. This will help ensure that the existing biodiversity is protected and that restoration actions improve biodiversity.
