''Poa flabellata'', commonly known as tussac grass or just tussac, is a tussock grass native to southern South America, the Falkland Islands, South Georgia and other islands in the South Atlantic. It was introduced to the Shetlands,〔Stace (2010) pp. 1013-1014〕 Scotland for basket making in 1844,〔(【引用サイトリンク】 title=''Poa flabellata'' )〕 and possibly as a source of fodder because of its ability to grow in hostile conditions.. It grows in dense clumps, usually about high (although they can be much taller), on wet coastal land and is a dominant feature of much of the landscape. == Associated organisms == The plant community dominated by ''P. flabellata'' is widely used by birds and mammals. Breeding colonies of southern fur seal, elephant seal, Magellanic penguin, macaroni penguin, and albatrosses are all found amongst tussac grass on South Georgia and elsewhere. The austral thrush is predominantly found in this habitat on the Falkland Islands, with tussocks being used as nesting sites.〔Collar (2005) pp. 677-678〕 The South Georgia pipit also uses the tussocks for nesting. On South Georgia, it is a principal food of the introduced reindeer, which has caused considerable environmental damage, including erosion and replacement of tussac grass by the introduced annual meadow-grass.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Poa flabellata」の詳細全文を読む スポンサード リンク
