In recent years, the Trust has become concerned by an apparent negative impact on lesser horseshoe bat colonies when greater horseshoe bats are also present in the roost. 

To further our collective understanding of the extent to which lesser horseshoe roosts are being affected nationally, we are asking everyone who monitors lesser horseshoe roosts through the NBMP to complete this short questionnaire. To obtain a representative picture, it is just as important that we hear back from those monitoring roosts that are not affected.

If you would like to discuss the project with VWT, please contact us.
