Dr Phil Smith: Wildlife Notes July 2016

Frog (Phil Smith)

Apart from a one-day heatwave on 19th when temperatures reached an oppressive 32oC, the month’s weather was unexceptional. Rainfall seems to have been about average but it was often cooler than expected in the first two and the last weeks. Predictably, the Devil’s Hole slack gradually dried up, though there was still a little surface water in the deepest parts (see below).

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 10th 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.

Dark Tussock (Dr Phil Smith)

 

With small amounts of rain on only nine days during the month, May reinforced a statistically significant trend of lower spring rainfall here since 2000. A recent paper in the International Journal of Climatology confirms this trend for the UK as a whole, linking it to atmospheric pressure changes over Greenland brought about by warming in this part of the Arctic, which then impacts the north Atlantic Jet-stream.

Persistent cold winds from the west and northwest were an unwelcome feature of May this year. Although these reduced the variety of migrant birds and slowed the appearance of wild flowers and insects, our coastline still produced plenty of interest. Fortunately, occasional rain meant that what little surface water remained from the April drought was kept topped up. Therefore Natterjack tadpoles on Birkdale Green Beach survived throughout the month, though their growth rate was slower than normal.

Dr Phil Smith: Wildlife Notes April 2015

Dune Pansy (Phil Smith)

An almost constant refrain in my April notes since 2007 has been drought conditions in the dunes. Persistent high pressure meant no measureable rain fell between 4th and 25th April. This pattern is now well established, analysis of spring rainfall data from the Ainsdale National Nature Reserve weather station revealing a statistically significant decline since 2000.
