The Killarney National Park notice board about this wood reads:

The Yew Wood is unique in Ireland and one of only three in Europe and is the rarest habitat type in the Killarney National Park. It is listed under Annex 1 of the E.U. Habitats Directive as a Priority Habitat. The wood covers approximately 60 acres (25 hectares) and the trees are rooted into fissures in the bare limestone and some are over 200 years old. The trees cast a dense shade, resulting in very little ground flora, but the bryophyte layer (mosses and liverworts) is abundant.

Curiously the title on the notice board calls the wood "Rennadinna", but a Google search provided no references to this word. A Google search for "Reenadinna" however provided many with references to this woodland, so I have used that in the title to this submission.
