Plans to build up to 5,000 homes on a site that is said to be key to the UK's nightingale population have been condemned by environmental campaigners.
The Wildlife Trust said the move could cause "environmental destruction on a scale not seen for more than 20 years".
It comes after Medway Council approved the proposal for Kent's Chattenden Woods and Lodge Hill on Thursday.
Developers Land Securities say the area's 84 pairs of nightingales would be re-homed nearby.
The council estimates that the development, a former Ministry of Defence training camp, would bring almost 5,000 jobs to the area and says that affordable housing would account for one in four of the new homes.
Its plans also include three new primary schools, a secondary school and new health and leisure facilities.
