Abstract
Vegetation types, soils and air temperature of the Copahue Provincial Park (Neuquén, Argentina). This contribution deals with the vegetation, edafic and topoclimatic conditions at the Copahue Provincial Park. We discuss how soils and mean monthly air temperature influence the distribution of different vegetation units such as high andean communities, forests, parkland, shrublands, steppe and wetlands. The former vegetation units are well correlated with exposition, soil characteristics and four thermic units.

Summary
Las unidades de vegetaci6n se definen se&n su fisonomia. Para ello se realiz el estudio de fotografias a6reas dei Instituto Geogrifico Militar, disponibles dcl afio 1984, a escala 1:60.000. La figura 1muestra 10svalores de temperatura media del ines de enero que oscilan entre 6,0 'X y -4,5 QCen el Area en estudio (Fig. 3). La regi6n norte, en cercanias del lago Rinciin, present a los valores mas elevados de temperatura, entre 9 % y 6 6'C. Que las unidades con valores de temperatura quo oscilan entre 0 C' y -1,5 V, en cercanias a1 lago Caviahue, se corresponden con zonas de dominio de Araucaria araucana, mientras que 10s del Area circundante, se encuentran entre -1,5 QCy -3,O VC. Respecto a la vegetacibn del Parque I'rovincia1Copahue, se ohservan amhientes hien diferenciados, que corresponden a: vegetaciiin altoandina, estepa, mallines, hosques de lenga, araucaria y matorrales de iiire (Fig. 3). Los suelos dominantes son Vitrandepts mollic, bien drenados, profundos, de textura franco-arenosa en todo el perfil, de secuericia A,C. E n el Brea de estudio, las existencias de pehu6n se presen-
