Butterfly Conservation.s formal butterfly couinting season runs from the begining of April to the end of September , with 32 'Transects", as the set routes are called, being walked weekly by volunteer recorders. Two of us from Martinstown record on the Dorset Wildlife Trust reserve at Tadnoll. This year's results have been rather disapointing, with a total of only 849 butterflies, a severe drop from the 2034 last year. I am wondering if this is a result of the very hot summer, as my bees have gathered only about a tenth of their usual crop of honey and so, though very active, ( flying 10,000 bee-miles per day!) seem not to have been able to collect much nectar. Maybe the butterflies have had the same problem and were short of food.
.
The species mainly affected were
Red Admiral (above, on this years excellent crop of
Blackberries), Small Tortoiseshell,
Meadow Brown and
Gatekeeper. Only the three
White species seem to have
done well, perhaps benifiting from the cooler weather which finally
arrived.
Now only the computer inputting remains to be completed, with the records going to the county butterfly recorder, and then, if he is happy, into the national records. These butterfly records are a very sensitive indicator of the state of the country's natural resourses and an important element in the fight to combat global warming.
