Who National Trust
Management type

Thinning

When 2012
Bat species affected Soprano pipistrelle, noctule, Myotis
Activity involved Felling of coniferous trees  and thinning of remaining deciduous trees
How was that activity modified

The targeted felling area was assessed for potential impacts on bats through an April walkover survey, and autumn emergence and dawn survey immediately prior to works. Trees were categorised according to the Bat Conservation Trust’s ‘Bat Surveys Good Practice Guidelines’. Wherever possible (within the constraints of visual amenity and public health and safety that were a central reason for the works going ahead) features identified with the potential to support roosting bats were retained.

What were the results

Twelve trees were initially identified as having the potential to support roosting bats, and six were considered unavoidably impacted by the proposed works. Of these, after closer inspection four were categorised as either having features which may have limited potential to support bats (category 2) or as having no potential to support bats (category 3). One of the four was retained as the limb that had been of health and safety concern had naturally fallen to the ground, and the other three were felled (one in sections and another with its root plate left as habitat) following a negative result from the emergence and dawn surveys.

 Two trees were categorised as having potential for use by single bats (category 1) one of which was upgraded to highly suitable features capable of supporting larger roosts(category 1*) following further inspection. Both trees were retained by removal of the stem above the features of potential bat interest, which addressed health and safety concerns whilst ensuring that the potential for bat roosting was retained.
