April Showers

Or more prolonged outbreaks of rain! Recent days have certainly been making up for the rather dry winter. The lakes which had been unusually low for the time of year have now filled up to the point where a number of the islands in Ibsley Water have disappeared.

On the plus side it has warmed up a little and this has resulted in something of an upturn in moth numbers. Last night saw nine species caught including early grey and brindled pug new for the year, there were also a number of oak beauty.

Spring migrants continue to arrive in low numbers, there are now several chiffchaff and  a few blackcap singing around the reserve and today we recorded our first terns of the year. The single common tern this afternoon was not unexpected, but the 4 Sandwich tern this morning were unusual and they were flying over heading south! The adult little gull was still around in the morning at least, it has been a near record season for them and we have probably already recorded about 20 individuals. Yesterday there were still at least 13 goldeneye and probably the same today, a hang over from winter with 50 or so sand martin and 5 or more swallow feeding over their heads.

There are now common dog violet, ground ivy, moschatel  and cowslip starting to come into flower. Ground ivy is normally very popular with the early butterflies, but recent days have been too cold and/or wet for them to have been flying.

As though the emphasise the changeability of the season I saw this intense rainbow as I went to lock up the Tern hide this afternoon, hopefully the ratio of rain to sun will start to change soon.

30 Days Wild – Day 6: And the Wind did Blow

And how it blew! And how it rained too, very unseasonal gales to tear at the trees and soak fluffy wader chicks. So it was with some trepidation that I got to Blashford today. Looking from Tern hide when I opened up I saw at least two of the small lapwing chicks and spotted one of the oystercatcher offspring too, although they should be well able to survive a bit of weather by now. A few of our trees had not done so well, no major fallers but several branches down, at this time of year, in full leaf and soaked with rain, the wind can really get hold of a branch twisting and breaking it off. Luckily the volunteers were in and between us we were able to walk the full length of all the paths clearing branches as we went and then returning to saw off the few larger leaning stems.

At lunchtime a smooth newt was spotted on the surface of the Centre pond, Jim then realised that it had been caught by a great diving beetle larva, these are ferocious predators but I was surprised that one would tackle a full grown newt.

The newt was struggling but it was hard to see how it was going to get the beetle larva off as it had its jaws firmly embedded. As we watched a second, equally large larva closed in and joined the attack, I don’t think the newt had any chance against two attackers. I knew they would tackle prey larger than themselves but this was the first time I had seen one take on something so large. The picture is an example of “Digi-binning” that is holding the digital point and shoot camera up to one eyepiece of the binoculars.

Unsurprisingly the moth trap was very quiet, I doubt many moths tried to fly and those that did probably had trouble getting anywhere they wanted to go. Amongst the few that did get out and into the trap was a very fresh mottled beauty.

The weather did improve a bit in the afternoon and there were quite a few insects flying as I went to lock up, lots of damselflies and various things nectaring on the flower heads of hemlock water-dropwort, one of the best food sources for lots of species at this time of year. I cannot identify them but the many insects include a number of sawflies.

Looking after a nature reserve can be rewarding, especially when you can work to improve habitats, allowing them to support more species and individuals, in the jargon increasing biodiversity and biomass. On a reserve such as Blashford Lakes there is the additional goal of increasing the accessibility of this wildlife to allow appreciation and enjoyment for people. Increasingly it is being realised that this is good for our health, diverse green space really matters to our wellbeing, individually and as a society. It is also a small push back against a tide of mass declines in species abundance and variety, to make a real difference to that needs action on a much larger scale than just a nature reserve.

So on Day 6 of  my 30Days Wild I have to confess to getting a little wild myself. I have already blogged about my tiny back garden meadow and we are doing work at Blashford to enhance the grassland to support more species. Species rich grasslands and meadows have been one of the fastest declining habitats in recent decades, with the accompanying loss of wild flowers, butterflies and the rest of the species such places support. Local Authorities and Government Agencies have a duty to enhance the environment where possible. There has recently been much publicity about the importance of grass verges for wildflowers, it has made national radio and some species are now almost only found by roadsides.  The Highways Agency publishes very good guidelines for the management of verges, round-abouts and other roadside grass areas, with the idea that managers of such places will have a best practice guide to follow.

So what made me wild? It was the close mowing, for the second time this season, of the large (probably 0.5ha or so) round-about at the end of the road where I live. This does not improve safety, to do this at most a couple of metres around the edge would need mowing, nor was it tall, no more than 30-40cm and the mass of corky-fruited water-dropwort was just coming into flower. The first cut dealt with the cowslips and much else besides, this is a relatively herb-rich grassland that is being systematically destroyed by close mowing and swamped by a layer of mulched cuttings each time. Eventually this will ensure it has only a tall coarse sward of cocks-foot, thistle and nettle and another vestige of our grassland heritage will have gone. I don’t know which particular arm of authority undertakes this mowing, but the guidelines have evidently not reached them! So long as there is careless disregard for such places the march to environmental mediocrity will continue and we may as well lay Astroturf and be done with it!

Normal service will be resumed tomorrow, unless the “Wild” part of 30 Days Wild takes hold again!
