Brimley Hill Mire is a small but exceptionally rich springline mire and a Somerset Wildlife Trust nature reserve. The site represents an excellent example of springline mire, a habitat special to the Blackdown Hills. A springline mire is where permeable greensand and impermeable clay sub-soils meet, creating springs and quaking bogs – the perfect habitat for bog-loving plants and animals.

A variety of species can be found at Brimley Hill Mire, some of which are nationally rare.

Round-leaved sundew, oblong-leaved sundew and pale butterwort, can be found here. These are insectivorous, that is they eat insects, worms, and other invertebrates. You can also see the striking, frilly, pink spikes of marsh spotted orchids. There is a rich community of sphagnum mosses too, particularly suited to the water-logged terrain. We’ve also spotted a very rare little sedge, known as the white beak-sedge, only found at one other site in Somerset, and the rare marsh St John’s-wort, present at only a few sites in Somerset.

Bare in mind it is very wet indeed underfoot!
