this beetle was found in the washland this July

I have had word that there are two nationally scarce water beetles on the Nevendon Reserve. I do not have their ID confirmation yet but hopefully this will come through by the end of this week. We have been finding water beetles in the ponds on site as well as the wash land area










The photographs are of water beetles found on the site. The larger one is the Great Diving Beetle – a number of invertebrate samples were taken from the ponds, the brook and the washland.

We have a bumper crop of great crested newt larvae in th

e ponds where upwards of thirty were seen amongst the weeds and open water The spring survey had a peak count of 84. The target is to reach a peak count of over 100 adult newts in 3 year’s time (fingers crossed)





Out of destruction comes new life & habitats…..

The power lines across the Nevendon Road site are supported by wooden telegraph poles. The local woodpecker population seem to be keen on these upright dead trees despite being treated the woodpeckers put massive holes into the sides of these poles. A local contractor had access recently to replace the poles in the middle of the washland area. I asked him what machinery he was going to be using – fearing that as an ecologist I was about to place restrictions on his normal day to day works he said that ‘they would be using a 4×4 vehicle, a cherry picker and a tracked 360 digger’. ‘No problem’ I said ‘just one thing, if you make a mess (i.e. rutts and tracks) do you normally tidy this up?’

He stated that ‘oh yes we would want to make sure everything is tidy when we leave’. I wanted to make sure that I got some┬ácompensatory┬áhabitat as a result of the works – so I asked ‘Can you leave the wheel ruts and the track markss please?’ To his amazement We don’t normally get asked to do that, normally we are told off for leaving wheel ruts and tracks on private land. I explained that I wanted to create small ponds and linear ditch features on the wash land. The easiest way to do this is by machine digging holes in the ground or in this case the wheels and tracks left behind the work on the telegraph poles.

The mess left over was a little concerning. I was over the site with our botanist and I showed him the wheel or track ruts. He basically said ‘they got a bit stuck then?’ and finished off with ‘that would help with maximising the biodiversity of the site’
