Tuesday is one of our two regular volunteer days at Blashford Lakes, this week’s main task was further work to improve the grassland habitat along the western shore of Ibsley Water. We have had a long-term project to remove bramble, nettle and willow that has been threatening to take dominate. This shore was remodelled into a steep bank using the topsoil removed from the gravel pit surface when it was first dug, conditions ideal for the development of nettle beds and bramble thickets. To reverse this we have been mowing to allow grass and perennial herb species to get the upper-hand. This has been targeted work aiming to take out only the least desirable species. Even the nettle beds have elements that we leave, such as any patches with nets of peacock and small tortoiseshell larvae.
Alongside the nutrient-rich soils there are poorer patches and these have a more interesting flora including a number of bee orchid.
At the end of the day I went out to Gull Island in Ibsley Water with the bird-ringers to colour-ring a sample of the black-headed gull chicks. We have been doing this for a number of years to find out where the birds from this recently established colony go to and if the chicks reared here return to breed in later years. We managed to catch and ring thirty chicks during our short visit, a good sample.
209C gets a ring, where will it go and will it come back?
In the evening I came across a female stag beetle on the fence in the garden, the first female I have seen this year. The day ended on a fine calm note and so I decided to head out to listen to the nightjar again. One came and perched on a branch very close by and gave great views. I never tire of watching and listening to nightjar and to have the opportunity to do so just a few minutes walk from home is wonderful.
Sunday and almost mid-summer and I was at Blashford where we were hosting Fordingbridge Astronomical Society’s Sun Day. They had telescopes set up so that the sun could be safely viewed and some of its usually hidden secrets seen. However, the clouds did not play along and the sun remained hidden resulting an early end to Sun Day.
However Sunday continued and in the afternoon I was leading a walk to look for dragonflies, damselflies and miscellaneous other bugs. Unfortunately the clouds had continued to gather and light rain started to fall, making insects hard to find.
Despite the rain we did see four species of butterflies, an optimistic migrant red admiral at the Centre Pond, common blue and meadow brown hiding in the meadow and a hundred or more peacock caterpillars in front of the Ivy North hide.
In the morning it had been a little less wet and I had found a few more insects and other invertebrates out and about, including this snipefly, with huge eyes.
There are also a lot more siders about now.
Mid-summer is also a time for flowers, perhaps a surprise to some of our visitors, but Blashford is actually quite a good site for orchids, we have several species and sometime sin quite large numbers. This despite most of the being a “Brownfield” site, we tend to think of orchids as plants of ancient downland sites, but many will colonise freely if they get the chance. The bee orchids are at their best now and some can be seen on bank on the side of the main car park.
