At Radnorshire's rooftop, it's hardly surprising the vegetation is dominated by sub-montane shrub heath, some of the finest in Radnorshire, undamaged by fire or over-grazing for many years. 

Boggy pools are dimpled across the nature reserve and are home to a range of water beetles and other mini-beasts that can tolerate the acidic, peaty water.  Over forty species of beetle have been recorded, including the ground beetle and the heather weevil.

The hen harrier can sometimes be seen gliding across the heather moorland along with other birds of prey.  Roe deer and the brown hare are one of the few mammals that may be spotted flitting about whilst the lichen called the 'reindeer lichen' Cladonia portentosa can be found across the reserve on dead bilberry stems. The more noteable Trapeliopsis glaucolepidea and Micarea nitschkeana lichens are also found here.
