Ecological Consultants in Cambridge

If you’ve been asked for a bat survey in Cambridge, then read on. This article has been written with you in mind…

12 of the 17 native bat species make their home under the vaulted ceilings of Victorian terraces and windswept attics of the historic buildings that characterise the city centre.

As you move out towards the Cambridgeshire countryside, new developments begin to replace the old. Whilst this construction represents the city’s growing prosperity and status as the UK’s next Silicon Valley, the expansion poses a substantial threat to bat roosts. Especially as these developments push further and further out and increasingly disrupt their natural habitats. 

Planning for the future

The various local authorities have grand plans for the future Cambridge and the surrounding regions. South Cambridgeshire District Council and Cambridge City Council have invited development proposals small and large on over 16,000 hectares of land encompassing swathes of the countryside and the city of Cambridge itself. These sites, if approved, will form an integral part of the Local Plan that will set the framework for the changing face of Cambridge over the next 20 years.

Great news for planning professionals, developers and homeowners alike. But what does it mean for bats?

Ultimately, big chunks of this development work will involve the renovation of existing buildings in poor repair both in the city of Cambridge itself and the wider countryside. Admittedly, not all of these buildings will contain bat roosts, but there’s always a possibility. Damaged roof linings, cracks in the stonework and more besides allow bats easy access and egress to a sheltered, dark habitat. 

Then there are caves, trees, and other natural hollows to consider. These are plentiful in the ancient fenland that characterises the Cambridgeshire countryside and envelops the urban centres. Many have provided a natural safe harbour for bats for centuries. So, if you’re considering development that might impact upon these roosting sites it’s in your interest to take appropriate action. 

After all, it’s your legal obligation to avoid disturbing bat roosting sites.

That’s where a bat survey comes in. 

Preliminary bat roost assessment

Simply put, your bat survey will inform you of the presence or absence of the three triggers for an emergency survey. Specifically:

  • The presence of bats
  • Evidence of their activity (droppings, carcasses etc.)
  • Access to features suitable for roosting

Should your report indicate that animals or evidence of their activity are present, or the roost suitability of your site is significant enough, your local planning authority will expect you to undertake a further survey effort before determining your application.

We appreciate that this is often an unexpected and very unwelcome expense. Though it’s perhaps better to consider your bat survey as an investment. Whether you’re planning a barn conversion in one of the medieval towns that dot the countryside or an urban mixed-use development, the consequences of getting things wrong range from severe to extraordinary. The disturbance of a bat roost or harm to animals is a criminally prosecutable offence that can result in a custodial sentence. Recently this cost Bellway Homes £600k in fines and another £100k or so in court costs and a mandatory donation to the Bat Conservation Trust, on a site in Greenwich.

However, we’ve never had a client’s planning application refused where bats are present. 

In fact, we have secured hundreds of planning consents for clients in Cambridgeshire alone.
