Moth numbers have declined more in UK woodlands over the last half century than in any other habitat, according to a new study.
A team of scientists led from Rothamsted Research found that populations have more than halved in broadleaf woodland, compared to average losses of 34% across the rest of the country.
The authors – who also looked at the possibility that over-grazing by deer and less woodland management might be responsible – say the reasons for the declines are still unknown, but climate change may play a role.
Lead author, Dr Dan Blumgart said: “It is likely that this has driven at least part of the decline observed in woodlands. But this can’t explain why the declines have been worse in broadleaf woodland compared to other habitats.”
