Nasjonalt rødlistede karplanter i Nord-Trøndelag

Abstract

The draft of a national red list of vascular plants has been checked for the occurrence and status of the taxa in Nord-Trøndelag. The report deals with 15 native taxa and agricultural archaeophytes, two introduced taxa with an interesting history in Norway, and one apomictic taxon. Fifteen of the municipalities in the county are involved. The highest numbers of red list taxa have been found in Steinkjer (5), Verdal (5) and Snåsa (4). Several taxa are known from only one or a few sites, and a considerable part of the information derives from rather old herbarium specimens, many having inaccurate site information. The review states that field investigations are needed to check the exact localisation of sites, the status (for instance population size) of the taxa, and the status of sites as regards impacts, need for management, etc. It is recommended that the report is followed up with a sirnilar survey of "regional responsibility taxa".
