|Scientific Name:||Athrotaxis cupressoides|
|Taxonomic Notes:||This genus was formerly included under the family Taxodiaceae. That family is now merged with Cupressaceae (see Farjon 2005).|
|Red List Category & Criteria:||Vulnerable B1ab(ii,iii,v)+2ab(ii,iii,v) ver 3.1|
Calculations of extent of occurrence (EOO) and area of occupancy (AOO) for Athrotaxis cupressoides are based on herbarium specimen distribution data. While EOO appears roughly in accordance with a map published by Brown and Hill in Farjon and Page (1999), the AOO could be too small if a grid size of 2-4 km were used. This is because there are many stands known that were not sampled for the herbaria consulted. Using a 5 km grid the species qualifies for a Vulnerable listing under the observation of slowed but still ongoing decline because of various threats. The population is also considered to be severely fragmented.
|Range Description:||Endemic to Tasmania (Australia), occurring mainly on the Central Plateau, the Great Western Tier and westward mountains, more scattered in the south of the island. The extent of occurrence and area of occupancy, based on herbarium specimens and standard IUCN mapping techniques, is estimated to be 12,818 km2 and 650 km2 respectively. Estimates of the area of occupancy for the main vegetation types that A. cupressoides occurs in, are considerably less: 24,279 ha (Balmer et al. 2004). Occurs between 700 and 1,300 m asl.|

The population has declined significantly in the recent past but the actual size of this reduction is unknown. The current decline is slower but it has not ceased.
|Habitat and Ecology:||A relatively small slow growing, long-lived tree of the subalpine zone where it occasionally forms dense stands. Often found in fire protected sites such as bogs, around lake shores or alongside streams. Usually associated with conifers such as Diselma archeri and Pherosphaera hookeriana and angiosperms such as Eucalyptus coccifera, Orites acicularis, Richea scoparia, R. pandanifolia and Nothofagus gunnii.|
|Major Threat(s):||This species is extremely fire sensitive and much of the total population was fire-killed mainly in widespread fires on the Central Plateau in 1960/61. Regeneration of the species is limited by grazing, mainly by introduced sheep and rabbits, of which the latter remain a problem. Dieback in which a species of the oomycete genus Phytophthora may be implicated occurs at some high altitude sites.|
|Conservation Actions:||Over 90% of the remaining areas of the species are now within IUCN Category I-IV reserves, especially within the Tasmanian Wilderness World Heritage Area.|
