Environmental building rules 'a challenge'
Follow us on
Enforcing environmental laws forcing developers to improve wildlife habitats will be a “challenge”, ecologists have warned.
Biodiversity Net Gain (BNG) means sites have to be assessed and developers must commit to delivering an improvement in biodiversity that lasts over a 30-year period.
Oxford University researcher Natalie Duffus said the system was “offsetting” damage to the environment.
Natural England said the measures would “leave nature in a better place” than before the development.
Ms Duffus has been measuring how accurately land has been scored under BNG assessments.
“There is a real trade-off between something that is simple and usable everywhere across the country, and with the ecological complexity and capturing all the different parts of a habitat.
“With BNG you are potentially damaging a habitat today and offsetting it with the promise of a future habitat. Making sure that happens is a bit of a challenge.”
Iain Delaney, of Captiva Homes which is currently building homes on the Isle of Wight, said there was “cost and complexity” for house builders involved in achieving BNG.
“But against the overall objective of enhancing the area post delivering development – I think its a meaningful step forward.”
