Fastest and Biggest yet Threatened

800-lobariapulmonariaIreland’s fastest growing lichen is the tree lungwort. Found in restricted areas of the West of Ireland it grows at a rate of 4 mm a year reaching sizes of 18 cm long by 3 cm wide. Its scientific name is Lobaria pulmonaria. Typically found on rowan, hazel and willow, its sensitivity to SO2 and shrinking habitat are placing it under threat in Ireland. Ireland needs to categorise this lichen as Nationally Scarce and take on International Responsibility for it. This specimen was photographed on a tree cut down in one of our National Parks.
