Includes bibliographical references (p. 25-27). “Seaside Bone Lichen (Hypogymnia heterophylla) is currently listed as Threatened under the Species at Risk Act. There are seven known populations of Seaside Bone Lichen in Canada, all of which are located within approximately 40 km of each other on the southern coast of Vancouver Island. The total known population size is thought to be around 2000 to 3000 individuals. The main threats to Seaside Bone Lichen are climate change and removal of, or damage to, its host trees. All populations face the risk of destruction or damage of host trees via the increasing severity and frequency of winter storms predicted with climate change. Three of the seven populations are located in areas frequented by visitors who could potentially damage trees. One of these also faces the risk of tree removal. The remaining three populations are located on a military reserve, where trees potentially could be damaged by efforts to improve habitat for vascular plant species at risk, and/or by military exercises. The species is limited by its extremely narrow habitat requirements. Feasibility of recovery is unknown at this time as specific impacts of climate change on this species are not known, and it is unknown whether these impacts can be avoided or mitigated”--Executive summary, p. iv. gccst Endangered species gccst Fungi gccst Nature conservation Canada.
