Although most NNRs are managed by Natural England, 88 are wholly or partly managed by other bodies approved by Council, under Section 35 of the Wildlife and Countryside Act 1981.
Dunkery & Horner Wood NNR is owned and managed by the National Trust. The majority of the reserve is within the grounds of the Holnicote Estate.
Horner Wood is an ancient oakwood that is an important site for mosses, liverworts, lichens and ferns. Local birdlife includes the pied flycatcher, wood warbler, lesser-spotted woodpecker, redstart and dipper. The woods are also home to 14 of the UK's 16 known bat species, including breeding roosts of barbastelle and Bechstein bats.
The NNR's upland area exhibits a complete range of heathland habitats showing a transition from 'true' upland down to lowland heath. Plant life includes fir and stagshorn clubmoss, Cornish moneywort and cranberry. The site is also important for its population of heath fritillary butterflies. Moorland birds seen here include stonechat and whinchat, curlew, ring ouzel and merlin.
Dunkery and Horner Wood is situated near the northern boundary of the Exmoor National Park, 7 km south west of Minehead and 4 km to the south east of Porlock. The nearest villages are Horner and Luccombe, both accessed via minor roads from the A39.

The nearest toilet and refreshment facilities are in Horner village. The village is also the starting point for two National Trust circular trails through the wood, one 3 km long, the other 8 km. Another 5 km circular woodland trail starts at Webber's Post and there is a 5 km circular upland walk that includes many sites of archeological interest on Dunkery Hill. The upland walk starts at Cloutsham Gate, accessed via a track from Webber's Post.
A family circular cycle route passes Horner Wood. This starts at the Porlock.
