Some of our rarest bats are tree-roosting species. It is likely that part of the conservation challenge centers around protecting sufficient numbers of their tree roosts. This is a difficult task; the features used by bats often fall apart or are selectively removed by humans to concerns around risk and health of trees.
Up until now, mitigation options have been limited, with bat boxes being the only option for compensating for roost loss. To improve the prospects of two tree-roosting bat species we are undertaking a five-year research project to see if we can create bat roosts in living trees – see ‘Improving the prospects for two tree-dwelling bat species’.In this article for the Arboricultural Association’s magazine, we provide an update on what we have been up to.
