All Bat species are protected by European and UK wildlife law and are a common consideration in development proposals. Our specialist bat surveyors and data analysts hold the highest-level bat survey licences issued by Natural England, Natural Resources Wales and Scottish Natural Heritage that include bat handling, mist-netting, harp-trapping and the use of acoustic lures.  We also have an in-house team of qualified tree-climbers, enabling the completion of roost inspections of trees that may be affected by development proposals.

We have completed bat surveys and assessment work in relation to diverse range of projects from building renovations to large-scale renewable energy projects and Nationally Significant Infrastructure Projects.  The survey methods employed in relation to these projects include:

  • roost inspections

  • emergence/re-entry surveys

  • tree climbing

  • transect surveys

  • monitoring at height

  • static monitoring

  • radio-tracking

BiOME possesses considerable experience in obtaining European Protected Species (EPS) bat mitigation licences for development projects and in the design and implementation of mitigation schemes.

We also have staff who are Registered Consultants under the Natural England Bat Mitigation Class Licence scheme (formerly Bat Low Impact Class Licence (BLICL)) through which we are able to register sites that contain low numbers of ‘low conservation significance’ bat roosts, which streamlines the process for the client.

Our kit list extends to a large number of SM2 automated bat detectors to allow us to complete long-term monitoring projects at remote sites.

We have completed bat surveys for a proposed mining development in southern Norway and undertaken extensive bat research projects in Morocco and Western Sahara.
