Let’s get outside, explore our creeks, and celebrate local biodiversity – one photo at a time!

European carp (Cyprinus carpio) uproot vegetation, degrade habitat and reduce water quality, competing with native species for food and space. Come along to help us remove some of these carp from our local waterway.
