Two-metre screens will be erected along a section of the Ring of Kerry road to protect a rare plant, the Kerry lily, and to allow roadworks to resume.
The €500,000 road improvements on the Sneem to Castlecove section of the tourist route were halted three weeks ago at the edge of a dry heath habitat which is a Special Area of Conservation aimed primarily at the Kerry lily (Simethis planifolia).
The Castlecove-Derrynane section of the Ring of Kerry carries thousands of buses each summer.
The lily, regarded as vulnerable to extinction, is protected under the Flora (Protection) Order of 1999. It is an offence to pick or disturb the plant.
The Kerry lily is only found in dry heath ground near the sea, according to An Irish Flora by DA Webb. The few square kilometres of the Glanlough area where the roadworks have been halted along with the nearby Derrynane locality is the only district in Ireland in which it is found outside of the south of France, Spain, Italy and the Mediterranean islands.
Council engineer Fionán McCarthy said the roadworks would resume when the screens were erected.
