Help us document the biodiversity at Briar Hill Preserve using iNaturalist. City Nature Challenge is a global celebration of biodiversity in and around urban areas. Over 1.9 million observations and over 50,000 species were identified by 73,000 participants in 2023.
We will work to document as many trees, plants, animals and insects we can find at Briar Hill!
