River Sampling, Thursday 18th June

With the kind permission of Granta Park, we conducted our first foray from their premises on the Left Bank (south) of the River Granta.

The first sampling, in the Sluice Wood area on good-looking gravel but under shade, having produced almost nothing, we did much better working from the side by culverts in open sites near the new buildings and then in front of the Hall. Populations were generally modest but diversity rather good.



A Three-Spined Stickleback appeared to be a female in spawn. Demoiselle or Damselfly nymphs were plentiful, a few of good-size having over-wintered, many smaller ones recently hatched. We saw no Caddisfly larvae. Of the crustaceans, we found Freshwater Shrimps in good numbers, and one Water Hoglouse; of the molluscs live Pond Snails and one live Ramshorn, but no bivalves; of the worms, a few Leeches and one Sludge Worm (Tubifex).



A general shortage of water plants was compensated by a Water Speedwell and a Water Figwort, both fine specimens, neither species often in our records.

The Aims of Abington Naturewatch

At their meeting on 9 April 2005 the members approved this revised version of the aims of Abington Naturewatch:

  • To monitor and record the wildlife (fauna & flora) within the borders of the Abingtons;
  • To encourage protection of our wildlife, maintain its quality and foster its diversity;
  • To promote awareness of the richness, potential and problems of the natural environment of the Abingtons;
  • To cooperate in improving access to the local natural environment for the benefit of all Abington villagers.

Pat Daunt, Founder

The organisation is informal and communication is by email if possible; members are notified of events from time to time. Contact details are maintained by a small "project team". There is currently no membership fee as costs are covered by voluntary contributions at events.

Members are encouraged to report notable sightings of flora and fauna within the Abingtons to the appropriate sector coordinator and an illustrated record is published annually.

A map of the area covered, with some features noted, is available here: http://maps.google.co.uk/maps/ms?ie=UTF8&hl=en&msa=0&msid=213774935674882866424.00000111dca2be9f06ab8&z=13>
