HANTS & SURREY BORDER DRAGONFLY GROUP ______________________________________________
Formed in 1989 to record the local Dragonfly species.
The area chosen for the main research effort was a block of 16 ten-kilometre squares giving some overlap into Surrey and Berkshire.
66 76 86 96
65 75 85 95
64 74 84 94
63 73 83 93
A considerable amount of land is owned by the M.O.D. which provides some conservation possibilities. Considerable mineral extraction has taken place in the area providing extra waterbodies for the expansion of the Dragonfly population.
The area has several rivers and the Basingstoke Canal which has been the subject of much research following the re-opening to boat traffic.The Canal has a basic problem with its water supply and as a result for much of the year the locks remain closed to traffic.The water is possibly reducing in quality and observation of the more sensitive Dragonfly species seems to confirm this. There seems to be a shift in species out of Hampshire, where nearly all the water is above Ash Lock,into the Surrey section,which has many locks.
The area also contains the prime site for Dragonflies in the United Kingdom.Thursley National Nature Reserve has some 26 species on a regular basis and can host immigrants,if they can be found in such a large site. The White-faced Darter has a tenuous hold on its only
remaining southern site at this reserve.
