We’re in the process of getting planning permission and listed building consent for the renovation of our grade II listed farmhouse in Gloucestershire. It’s completely dilapidated, unliveable and the roof/walls have many holes and structural issues, hence the requirement for nocturnal bat surveys.
Given the fact it’s not been lived in for 15yrs and the many available entrances for bats, we were expecting the worst, but have been pleasantly surprised. We had an audio survey over 5 consecutive nights, where the ecologist said he was expecting to hear 800+ bat calls, but it only picked up around 50. We then had 3 nocturnal visual surveys spaced 2 weeks apart, where between 4 and 12 bats were spotted each night, all common species and mostly ‘commuting’ (which I think just means they flew nearby) or foraging in the back garden. Over the 3 nights a total of 4 bats were seen either entering or emerging from the property, all common species. So all good news and over the phone the ecologist implied it would require minimal intervention; bat licence, which he said is a legal requirement given they saw even 1 bat enter the building, a temporary bat box in a tree during building work and a few bat tiles.
However, we’ve now had his final report and there seems to be a lot more in there than he implied over the phone, all of which will involve him visiting the property for many hours to ‘supervise’:
- bat licence (application fee appears to be £500, but he’d charge c.£2000; no idea if there is more to it than simply competing the form and attaching this report, but I’d hope so for £1500! Does anyone know?)
- another survey immediately prior to construction (ok, I can maybe understand this, something could change between now and then, but equally I thought the survey results were meant to be valid for a year, how much more do we need?!)
- all contractors must be briefed by the ecologist before works commence
- the roofing work will need to be supervised by a licensed ecologist, whilst also recommending it is done slowly by hand. This could take weeks!
All this for 4 common bats! I love bats, I love all animals in fact and we’re quite happy to accommodate them, but this seems a bit much to me. Anyone got any experience? Is this normal for so few bats and common ones at that?
He also wrote at the end that he found several disused and degraded birds nests in the property (I know what he means, an old one has fallen down the chimney), but there was no evidence of recent use. Despite this, he recommended that construction work only take place outside of their nesting season (so no work between Feb and Aug!) unless we have another survey done. Seems excessive again, no?
