Features such as rot holes, cracks, loose bark and old woodpecker holes (which have also recently colonised the eastern side of Ireland) can all be suitable for roosting bats. Unfortunately, our mature trees and the wildlife they support have for many years been under threat from misunderstanding and poor management. Many trees, thought to be dying or dangerous, continue to be unnecessarily felled or damaged by inappropriate tree surgery. It is not known how many bat roosts are been lost each year as a result of this type management. Legislation requires landowners and developers to carry out a bat survey for roosts prior to tree surgery taking place.
Trees are surveyed from the ground with the aid of binoculars looking for features capable of supporting bat roosts, including rot holes, cracks, splits, woodpecker holes, wound callus rolls and loose bark. These surveys can be undertaken at any time of the year.
