About 100 people helped record 254 species, from ruddy darters to green elf cups, at the Brandon Country Park Bioblitz on Sunday.
Eight experts were on hand to help identify some of the species found, using microscopes for the smallest and were still identifying species on Thursday. The final total is expected to top 300.
Bioblitz was organised by Norfolk’s Environmental Records Centre (NBIS) and forms part of Wildlife Recorders of Tomorrow a Breaking New Ground project in the Brecks supported by the Heritage Lottery Fund.
Su Waldron, of Norfolk County Council’s community and environmental services, said: “There was a very good range of discoveries, from flowering plants, to fungi, insects, birds, molluscs, ferns and even fish.
“Some amazing and very colourful fungus turned up in the woods such as green elf cup; purple amethyst deceiver and
coral fungus. A beautiful male ruddy darter dragonfly was spotted.”
