Wildlife Notes

October is traditionally the wettest month of the year but this one was the driest in living memory with measurable rainfall on only three days. It was also milder than usual with no frost. This was caused by persistent high pressure over Scandinavia, a pattern that in the recent past has often switched in winter to low pressure with westerly winds and high rainfall, as in 2015/16. We shall see.

A rather unremarkable month for weather, August had average rainfall and a couple of short warm spells but was largely characterised by cool windy conditions. My frequent visits to the dunes revealed a surprising lack of large insects, especially dragonflies and butterflies. Thus, after a gale the previous day, I called in at our premier dragonfly site in the Birkdale dunes on 8^th and was horrified to find not a single dragonfly or damselfly. This seems to have been a widespread phenomenon, local moth trappers also reporting a poor season.

Although June was wetter than normal in most parts of the country, this was not the case here. The first rain did not fall until 10^th and we missed most of the thundery downpours that caused flooding further south and east. Nevertheless, a few heavy showers and more unsettled conditions later in the month maintained enough surface-water in sand-dune wetlands for our Natterjack Toads to breed successfully in several places.

Although measurable rain fell on ten days during the month, quantities were very small and temperatures above average. September therefore ended up as another desperately dry month, the duneland ground water-table being the lowest recorded since the drought of the mid -1990s.
