Of Bats and Bureacracy, Part 2

By The_woodlouse @the_woodlouse
Brief summary of Part 1: the bat man checked for bats and found bat poo indicative of one bat, but couldn't rule out the possibility of there being more bats hidden between the felt and the tiles of the roof.  He then wrote us a bat plan which received the necessary approval from the bat people at Dorset County Council, once we'd resolved a few glitches (they initially failed to read the plans properly).
The bat plan (Dorset Bat Mitigation Plan/DBMP) sets out an approach to roof works that will minimise any potential disruption to bats.  Although the plan describes "a bat roost of low conservation significance", we have to act as though there may be more bats roosting in the space between the roofing felt and the concrete roof-tiles, just in case.  Had we known earlier about the need for a Bat Survey we could have carried out emergence surveys - checking at dusk to see how many bats emerge from the roof - and based the Bat Plan on more specific information.  Sadly, it was already October by the time we knew a survey was needed and at this time of year the bats aren't active in that way.  I'm not sure what they are doing, but it isn't flying in and out of roof roosts.
