Medieval forests, chases and warrens have been the subject of numerous studies in Britain[1], however, with some notable exceptions they have been largely ignored in Ireland, and even when these have been discussed, the focus has tended to be on woodland as a whole and indeed on the more recent history of these[2]. Alongside parks, these were landscapes over which the elite sought to control access to hunting, but also, in the cases of parks and forests, to control timber and wood resources. This is an area of study that is very amenable to an interdisciplinary approach, combining historical, cartographic and archaeological evidence for past activity and providing an insight into medieval manorial organisation and settlement[1]. The aim of this paper is therefore to collate and review the evidence for forests, chases and warrens in medieval Ireland and to examine their chronology, ownership and functions. [1] N.D.G.
