CAFF - Flora group
During the next few decades the Arctic will be strongly affected by forces within and from outside the region, including the impacts of global climate change, resource development, changes in numbers of wildlife species, increases in permanent residents, and burgeoning tourism. The relatively simple and often fragile arctic ecosystems are dramatically altered through changes to the species composition of the vegetation, destruction of wetlands, and thawing of ice-rich permafrost, as well as through feedbacks of these effects to global hydrologic and atmospheric systems. To preserve plant diversity, conservation programs must be guided by the biological requirements of species and ecosystem components as biological diversity ensures a healthy biosphere. Traditionally, conservation and research activities for arctic plants have not been well coordinated in terms of common direction, concerns, reporting, and information exchange. Except for two CAFF action items, Panarctic Flora Project (PAF) and Circumpolar Arctic Vegetation Mapping Project (CAVM), governmental and non-governmental groups are often organized bilaterally. Therefore, plant conservation and research activities have not had a fully circumpolar perspective. Arctic Lichen Data Map
As part of this task, a list of all lichens (1610) and lichenicolous fungi (250) recorded in the Arctic is presented in the Arctic Lichen Distribution Map on the Arctic Portal. For this purpose the Arctic has been divided into 28 regions with separate lists for every region. The highest lichen diversity is found in West Greenland, 851 species. Well investigated arctic regions of considerable size generally contain about 5-600 species of lichens. 133 species of lichens appear endemic to the Arctic according to present knowledge. That means they are not found anywhere outside the Arctic. 15 species of lichens have been recorded in all of the 28 arctic regions. To view the Arctic Lichen Distribution Map, please click here. |
