It’s easy to get distracted by meadows in spring. They are decked out in a shimmering cloak of buttercups and yellow-rattle, and birds are warbling from every bush. The contrast with the muddy vistas of November is as great as a caterpillar and a butterfly – and plenty of those are about too, come to think of it.

But not to be outdone, the woods are changing too. Our rarest local mammal is awake – well, nearly.

Hazel dormouse, handled under licence at one of the local monitoring sites. Not quite out of torpor, the state of reduced activity that hibernating animals return to in conditions such as cold nights. In fact, this particular nesting box held two half-dozing dormice.

A dormouse monitoring site consists of 50 nest boxes, which are very like bird boxes except they are set up with the entrance hole facing the tree. It is illegal to open them without a licence because dormice are given the highest level of protection under our laws, sadly for good reason – while no one would harm a dormouse on purpose, their numbers nationally continue to decline, mostly due to loss of habitat.

As I’ve mentioned in previous posts, we’ve managed to retain that habitat in my part of the North Downs more by accident than intent. Dormice like woodland with a dense understorey, as well as hedgerows that are thick and tall and not cut every year.

For a variety of reasons, these simple conditions are now hard to come by in the wider UK countryside. We are changing the environment at a rate wholly out of pace with nature’s capacity to adapt. But just sometimes, you stumble across something which reminds you of the depth of years that are within our forests, and the antiquity that deserves respect.

This is probably the largest tree that I’ve ever seen outside of the tropics. It is a beech in the wilds of Shropshire, with limbs as thick as a normal tree’s trunk.

It is tempting to wonder how many dormice have hibernated in its shadow over the centuries.
