4.1 Nothofagus obliqua Forests in Argentina
Nothofagus obliqua (Mirb.) Oerst. (Nothofagaceae, Hill and Jordan 1993), known
as ‘roble’, ‘pellín’, ‘roble pellín’ or ‘hualle’, is a tree species endemic to South
American temperate forests. It is under protection in Argentina, mostly within
national and provincial protected areas. However, because of its high wood quality,
similar to Nothofagus alpina (= N. nervosa) and Nothofagus pumilio and in order to
supply the timber trade, it is harvested in some of these protected areas under the
regulation of forest management plans. Roble pellín’s wood is pink yellowish in the
sapwood and brown to reddish brown in the heartwood, with a fine texture, homogeneous and right grain (Dimitri et al. 1997) and high density (1.220 kg/dm
3
for
green wood and 0.720 kg/dm
3
for dry wood; INTI-CITEMA 2003). It is characterised by high mechanical resistance, durability and low putrefaction due to the high
content of tannins.
