Housebuilders supply only half of promised nature-friendly features, survey finds
Nearly half of the nature-friendly enhancements promised by developers building new homes have failed to materialise, according to a study of almost 6,000 new houses.Developers are failing to keep legally binding pledges to boost wildlife when building new homes, according to the survey by University of Sheffield academics for Wild Justice.When researchers visited 42 completed housing estates in England to check if ecological enhancements including newly planted trees, bird boxes, ponds and hedgerows had been provided as stipulated by planning permissions, they found just 53% had been delivered.Many specific measures to boost wildlife had not been provided. Thirty-nine per cent of trees detailed on planting plans were missing or dead; 75% of bat and bird boxes were absent; 83% of hedgehog highways had not been provided and researchers could find no evidence of any of the bug boxes detailed in any of the developers’ plans.

Nearly half of the nature-friendly enhancements promised by developers building new homes have failed to materialise, according to a study of almost 6,000 new houses.
Developers are failing to keep legally binding pledges to boost wildlife when building new homes, according to the survey by University of Sheffield academics for Wild Justice.
When researchers visited 42 completed housing estates in England to check if ecological enhancements including newly planted trees, bird boxes, ponds and hedgerows had been provided as stipulated by planning permissions, they found just 53% had been delivered.
Many specific measures to boost wildlife had not been provided. Thirty-nine per cent of trees detailed on planting plans were missing or dead; 75% of bat and bird boxes were absent; 83% of hedgehog highways had not been provided and researchers could find no evidence of any of the bug boxes detailed in any of the developers’ plans. Nearly half of the native hedges promised did not exist and 60% of the planned wet grassland had not been created.
Labour has vowed to build 1.5m new homes during this parliament and the housing secretary, Angela Rayner, this week suggested that newts and other endangered wildlife were an obstacle to construction that the government would sweep aside.
New biodiversity net gain measures introduced in spring oblige new housing to create 10% more natural habitats than those lost to development, with these regulations implying that a housebuilding boom can occur alongside the government’s legal commitment to halt species decline by 2030.
Kiera Chapman of the University of Sheffield, the lead author of the report, said: “With their recent comments on newts and bat tunnels, Labour are creating a smokescreen based on the idea that there is a conflict between environmental and social goals.
“Our research has shown that developers are not only delivering poor outcomes for wildlife, but also for people. When it comes to priorities, this is not an either/or situation: humans need healthy green spaces to flourish.
