Bourn Walk

 As I needed to go to the Surgery in Bourn this morning and it wasn't raining, I walked over via the edge of the golf course where there is a well-established Hawthorn hedge which yielded quite a few clumps of Fungi, a couple of Slime moulds and several vibrant lichen species. There was a lot of water in the Bourn Brook but fortunately no flooding on the walk. 

August Riverfly Session

 The Bourn brook is very low with the dry conditions generally this year so we were not surprised to find the fauna quite restricted for our August survey of the species present compared with July (see Riverfly )

Riverfly Survey in Toft

Toft Bourn Brook Group is carrying out surveys of the invertebrate species in the Brook according to the Riverfly rules and regulations for acquiring the samples and then counting the species found in the water. The species that are monitored include Mayflies, Olives, Stoneflies, Shrimps and  Caddis flies. Timed samples are taken and then examined for the Groups shown on the circular chart and the numbers of individuals counted. We also found very young Loach and American Crayfish plus Beetles, various Midge larvae and Pond Skaters etc
