Threatened species recovery actions

Actions from Threatened Species Recovery Actions 2025 Baseline published by Natural England.

(Re-)introduction

Translocations of adult beetles to sites with suitable habitat

Education/awareness raising

Raise awareness among the public of this species as it's fairly large, distinctive and would be noticed by casual observers. Given the disjunct population, other populations are probably to be discovered.

Status survey/review

Targeted aerial surveys of potentially suitable sites

Untargeted habitat management

This species would benefit from untargeted habitat management to increase habitat mosaics, structural diversity, or particular successional stages
