We didn’t have a lot of knowledge about what it did. It’s dangerous for the trees but it’s also a public health issue. It’s been fascinating.”

The moth’s caterpillars cause damage to oak leaves, and also pose a threat to humans as they can cause skin irritation and asthma.

During 2020, the influx of visitors new and old to the Heath has created new challenges.

David said: “We have been watching the astonishing number of people coming to the Heath. W

And reflecting again on the award and his decades on the Heath, he added: “I feel privileged to be a guardian of this fantastic urban woodland, helping to conserve its biodiversity and see the enjoyment these trees give to the public.”
