The Ministry of Silly Walks


Now it should come as no surprise to my reader that this mouse’s life, at times, resembles a sketch out of Monty Python and on Friday I joined The Ministry of Funny Walks, or at least that’s the way it felt.

The Forestry Commission Ecologist had requested help to carry out a Bat Survey in the areas of standing timber that are to be thinned. I didn’t need asking twice, as apart from learning a new skill or new technique, work like this is a vital tool for maintaining the health of the ecosystem that is our local wood.

As I have written of previously, the forest is to start having the plantation conifers thinned out soon and there will be a long term replanting of native broad leaf trees. This will be occurring over a long period, and it will be the next century before this work is near completion. However, to carry this work out so that existing species are protected and not disturbed, this type of surveying has to be done before hand. As the law protects all Bats and here in Chopwell wood we have six species of bat, it is vital that this work is carried out toughly and systematically. In practice that means every tree has to be examined to look for possible roosting sites.

That can be a boring task as it really is like looking for a needle in that proverbial haystack. As on Friday we also had the difficulty of heavy rain, a difficult task was made even more difficult. As the underbrush is at this time of the year covered with Brambles, and to survey properly requires walking up and down making that examination of the trees, we had to wade through the brambles. I nearly considered putting a picture of my legs on here to show just how lacerated I became but as it would put people off, I decided against that idea. Additionally is the problem that because of the heavy undergrowth, its impossible to see the ditches and mounds, so as I am moving forward I was suddenly finding myself chest high in brambles and not waist high.

One of the areas that had to be surveyed, I knew was free of bat roost, as it is one of my regular routes so I do know it well. However, it still needs to be surveyed properly, not only to comply with the law, to ensure that the scientific data gathered is a true and accurate reflection of the roosting sites in the wood. Further, doing something like this can reveal other hidden gems in the wood, I know of a few hidden places where fungi will be emerging soon, as an example.

But after six hours of searching, my legs were aching and while it had stopped raining by the time we finished, I was completely saturated. Even my underwear was soaking and I was ready for a nice hot bath.

Incidentally, on this part of the survey we found seven potential roost sites, and latter the FC Ecologist will return with a ladder and Endoscopes to see if they are occupied. Finding the specific trees or sites will be easy as we used GPS to mark the exact location.

The work will continue in just over a week’s time, and all I can do is hope for better weather on that day. However, as it is vital work, I will be there no matter what the weather throws at us.

Incidentally, should we find that all of these locations are occupied then we can ensure the roosts are not lost by putting up additional roosting places in the form of bat boxes, thus ensuring that our healthy bat population is maintained.
