Tracking Fineshade's Dormice
The Hazel Dormouse is probably Fineshade's most special resident. The species is now so rare that it is vulnerable to extinction in the UK and has the very highest levels of protection.
In early 2020 plans were made to work out the distribution of Dormice in the wood. Which parts of the wood do they prefer? What are the Fineshade habitat types that suit them best? Woodland management is necessary for the production of timber, but how can that be planned in a way to benefit this vulnerable and rare species?
A new monitoring technique for Dormice had been developed and the Wildlife Trust for Bedfordshire, Cambridgeshire and Northamptonshire (WTBCN) had trialling it in one of their nature reserves in 2019. Rather than providing nest boxes, this method uses what are known as "footprint tunnels". A covered platform is suspended in the branches with inkpads and a sheet of cardboard inside. If a dormouse passes through, it walks over the ink leaving its footprints on the card. These cards are collected regularly and the footprints examined: Dormice leave a distinctive print with triangular shaped pads and out-turned toes. The tunnels have an advantage over conventional boxes and tubes as they only require the animal to visit, rather than to build a nest. Nor does checking the tunnels require a licence, since no animals are disturbed.
Friends of Fineshade working with WTBCN and Forestry England, decided to erect 100 footprint tunnels in two parts of the wood in 2020. We hoped to run the scheme in different areas in the following years.
Before the lockdown caused by the Corona-virus, a team of volunteers was formed who would erect and check the tunnels for footprints regularly during the summer months. A crowdfunding appeal enabled us to buy 50 tunnels and equipment, while another 50 were suppled by Forestry England. With the restriction on travel our plans have had to be scaled back but Fineshade residents have still managed to get 50 tunnels in place, during their daily exercise periods. On 7th May, cards were stuck inside, pads were inked and fingers crossed that Dormice would find the tunnels and wander through leaving their footprints behind.
By 20th May it was clear that at least 3 of the boxes had had animals inside them. But were they Dormice? The smudged tracks have gone off for analysis but really didn't look conclusive. Still, it's early days and we're hopeful that more definite footprints will be found later.
We'll be reporting on what we find as the summer proceeds.
