此物種詳細資訊 Inaccessible Is. (sub-Antarctic)
來源： Dean et al. 1994
The soils surrounding the entrances to nest burrows of petrels and shearwaters on the plateau at Inaccessible Island were covered by dense monospecific mats of Holcus lanatus or Poa annua. P. annua is also found near albatross nests.
生態系統變化: Nitrogen rich soils apparently favour species such as Poa annua, while adversely affecting the vigour of indigenous ferns (Huntley 1971, in Dean et al. 1994).
