NBMP Field Surveys in July

BCT have issued updated Covid-19 advice which means field surveys can be undertaken this year, with some limitations. The summary for Somerset is on our website, with the full updated advice on the BCT website.

This survey aims to find out how noctule, serotine, common pipistrelle and soprano pipistrelle are faring across the UK.

You can either:

  • help out with an existing field survey,
  • or if more experienced take on a field survey yourself, choose from the list of Somerset surveys up for grabs below.

The field survey involves visiting your site on two evenings to carry out surveys, during a triangular walk in a one Km square area.  The first survey should be between 1st and 15th July and the second survey between 16th and 30th July.  The survey begins 20 minutes after sunset and usually takes about 90 minutes.
