Frog Rush - photographed by Kristian Peters
A First for Leicestershire and Rutland
We’ve just had conformation from Dr. Tom Cope at Kew that the rush found on the edge of Lagoon 1 just in front of the Centre is Frog Rush (Junctus ranaruis). This Frog Rush is the first recorded in Leicestershire and Rutland.
On 3rd September 2011, 191 species were identified at the BSBI (Botanical Society of the British Isles) Field Meeting held at Rutland Water Nature Reserve.
