Some people pictures from last Saturday’s Crossness invertebrates event

As previously reported there was an excellent turnout of 27 – mainly locals – for last weekend’s (July 4th) London Natural History Society-led event at Crossness Southern Marsh on Erith Marshes, looking at lesser-known invertebrates. The area is part of a Metropolitan (London level) Site of Importance for Nature Conservation.

LNHS experts on hand were Tristan Bantock and Mick Massie on insects, ornithologist George Kalli and leading botanist Rodney Burton.  Attendees included members from the Ruxley Gravel Pits nature reserve, Lesnes Abbey (Woods) Conservation Volunteers and the Friends of Crossness Nature Reserve group.

While we wait for a definitive list of species found to be compiled, here are some of the other characters that were to be seen (Photos by Site manager Karen Sutton and walk leader Chris Rose – with his LNHS hat on).

The volunteers from Lesnes Abbey Woods clearly prefer shadier habitats, and took advantage of a Reedbed to take some respite from the blazing sun!
