Habitat work and a monitoring scheme have helped hazel dormice thrive at a National Trust site, despite declines elsewhere, experts have said.

Killerton National Trust has 100 nest boxes across its estate in Devon. Rangers weigh and record details of each mouse between April and October.

The trust said the animals "continue to thrive" in the area - a sign it was "doing something right" by creating a "healthy, diverse and well-connected habitat for wildlife".
