¡P         Summary: Pilgerodendron uviferum (Don) Flor., Cupressaceae (common name "ciprés de las Guaitecas") is the native conifer with the widest geographic range of the temperate forest from southern South America, particularly when compared to its only two closest relatives Austrocedrus chilensis ((Don) Florin et Boutleje) and Fitzroya cupressoides ((Mol.) Johnst.).  In Argentina, Pilgerodendron is restricted to a small number and isolated populations along its distribution.  This study analyze the conservation status of Pilgerodendron known populations in Argentina based on information of the physical characteristics of the habitats, vegetation, and disturbance types in eight different locations. The majority of the studied populations are protected within National Parks, generally they are restricted to waterlogged sites, and they consist of small groups of individual trees and not continuous forests. At some of the locations signals of human-induced disturbances were observed, mainly logging or browsing by cattle.  This was the case for the Cordón Serrucho population which is not currently included in any protected area.  Adequate strategies for a better preservation and restoration of degraded Pilgerodendron populations include cattle grazing exclusion and the creation of a protected area.
