Dormice 'thrive' at Killerton National Trust site in Devon

Hazel dormice at the National Trust's Killerton estate in Devon are maintaining stable numbers, bucking a 59% national decline since 2000. Rangers attribute the local success to long-term habitat management, including hedgerow care and a monitoring programme using 100 nest boxes across the estate where mice are weighed and recorded between April and October. National surveys suggest warmer summers may be helping a recent upturn elsewhere, prompting cautious optimism among conservationists.

  1. Hazel dormice hold steady at Killerton estate while UK numbers fall

    Hazel dormice at the National Trust's Killerton estate in Devon are maintaining stable numbers, bucking a 59% national decline since 2000. Rangers attribute the local success to long-term habitat management, including hedgerow care and a monitoring programme using 100 nest boxes across the estate where mice are weighed and recorded between April and October.

    Why it matters

    The hazel dormouse has disappeared from half its historic range in England and is classified as vulnerable to extinction in the UK. Killerton's stability offers a rare positive case study showing how targeted woodland and hedgerow management can support the species. The estate's 25-year monitoring dataset provides valuable evidence for national recovery strategies.
