Abstract: Although maërl beds are both of economic importance and conservation interest, data on the distribution of beds and their associated communities are lacking in Irish waters. This report describes the spatial distribution and volume of the maërl resource (Lithothamnion corallioides, Phymatolithon calcareum) along the west coast of Ireland from Donegal to Cork. Taking an average thickness of 2m (range: 0.1 – 3m) the current study estimates that the total national exploitable maërl bearing resource is of the order of 3 x 10^6 metres cubed. The Report outlines guidelines for the exploitation of this natural resource, which because of its extremely low growth rate, cannot be considered a renewable resource in the strictest sense.
