In 2006 the National Parks and Wildlife Service of the Republic of Ireland commissioned a review of the status of the seven hawkweed (Hieracium) species endemic to Ireland: H. argentatum, H. basalticola, H. hartii, H. hesperium, H. hibernicum, H. scullyi and H. sparsifrons. Only one species is widespread, the remainder being rare or very rare. Hieracium is a genus in which species are difficult to identify and require expert survey. The project involves compilation and review of existing data, and field work in 2006-2008 to assess their current population sizes and determines their needs for conservation. Live material is also being collected for seed banks and cultivation in the National Botanic Garden, Glasnevin.
