For several weeks now there have been contractors working up at the Linwood reserve working to open up an areas of mire habitat that had become seriously shaded. This happens more or less imperceptibly, in this case it was easy to think the area had always been continuous woodland , but the flora told a different story. Many species present, although declining, were ones that do not tolerate being heavily shaded. In addition when the trees are looked at more closely it was obvious that many were no more than twenty or thirty years old. The Our Present, Our Future (OPOF) New Forest National Park project had a strand that was dedicated to helping to restore habitats such as this and it is this project that has enabled the heavy work to be done.
The oak and beech trees have been left alone, the opening up has been achieved by felling birch and pollarding willow. Some trees have been ring-barked to leave them as valuable standing deadwood habitat. It will be interesting to see how species such as white sedge and bog myrtle respond to having access to more light in the years to come.
Last night was very mild and I was looking forward to seeing what the moth trap had caught. The trap was against the wall of the Centre and there were 45 “November” moth on the wall alone! November moths are hard to identify reliably as there are a few very similar species, so I lump them together when recording. Other moths included three merveille du jour.
There were also late large yellow underwing and shuttle-shaped dart as well as more seasonable black rustic, yellow-line Quaker, red-line Quaker, chestnut and dark chestnut.
In all there were 16 species and over 70 individual moths, other notable ones were a dark sword-grass and two grey shoulder-knot.
We have been doing a fair bit of work around the hides recently, mostly aimed at improving the views from them. Tomorrow it is the turn of Ivy North hide, so I expect there will not be much to be seen in the northern part of Ivy Lake during the day. With luck I will get some sight-lines cut through the reeds, so perhaps the bittern will get easier to see, if it is still around.
