Applications for two mobile phone masts on a foothill of Nephin, one of Mayo's highest mountains, have been turned down by An Bord Pleanála, because of their impact on a landscape described as "visually valuable, sensitive and vulnerable".
Senior bord inspector Mr Kevin Moore stated that the masts, planned by Vodafone Ireland PLC and Meteor Mobile Communications, would be "significant obtrusive developments" which would grate against the sensitive backdrop of the 806 metre high mountain.
Both Vodafone and Meteor appealed a decision by Mayo County Council last August to refuse planning permission for the 24 and 25 metre masts, respectively, at Doonbredia, Lahardane, Ballina.
Mr Moore pointed out that Doonbredia Mountain forms part of Nephin, being the foothills climbing its northern face. Nephin Mountain and Lough Conn form the significant natural amenities in this area.
Mr Moore explained that the area in which the proposed sites is located is referred to as the "North Mayo Moorland" area and the masts would be visible over a vast area to the north, east and west.
There was an evergreen forestry surrounding this site but most of the support structures would be readily visible above the forestry plantation.
Regarding the proposed Meteor mast, Mr Moore stated: "Even if the forestry on this bogland were to reach maturity the mast will rise 9-11 metres above it and would grate with the distinctive backdrop that is Nephin".
In its application, Vodafone claimed the structure would not be conspicuous because forestry would provide an absorbing backdrop. The reason for seeking a 24 metre structure was to keep it above the tree line to maximise coverage and to facilitate a second operator.
Mr Moore said it would be sited in a prominent location on the northern slopes of Nephin Mountain, an area acknowledged in the current Mayo County Development Plan as "a sensitive landscape".
It was considered that the proposed support structure would constitute a highly obtrusive development notwithstanding its siting in an existing young forestry plantation.
One of the submissions received by an Bord Pleanála was from Mr Steven Canty, who objected on the grounds of health impacts, visual impacts and proximity to national monuments.
An Taisce also objected, stating that the proposals was located in an area of special scenic importance.
