La Picada
aus Degupedia, der freien Wissensdatenbank
La Picada ist ein Studienort im Nationalpark Vicente Pérez Rosales (41°02'S, 72°30' W) in der Region Los Lagos (Region X) in Chile.
"Between December 1980 and May 1985, live-trapping studies were conducted in the precordilleran Andes (Parque Nacional Vicente Pérez Rosales, NW Volcan Osorno; 41° 02'S, 72° 30'W; 84 km ESE Osorno, X Region, Chile). The locality ("La Picada") contains virtually undisturbed Valdivian temperate rainforest between the lower park boundary (400 m) to tree line (1,100 m). The vegetation has been qualitatively described (Meserve et al., 1982, 1988; Patterson et al., 1989). The two sites (Plot 1 and 2, respectively) fall approximately into Type 6 and Type 7 categories of Nothofagus dombeyi-dominated Valdivian forests in the mid-elevational (400-950 m) precordilleran Andes of the Chilean Lake District (Veblen et al., 1983). Quantiataive vegetation analysis was conducted in summer (January-March) 1984, and repeated for certain components in winter (July-August) 1984 using point-centered quarter quadrats at each trap station (Mueller-Dombois & Ellenberg 1974). Measurements included canopy cover (using vertical photgraphs taken with a 35 mm camera and 35 mm lens measuring a 63° field), number of fallen logs (> 7.2 cm diameter), estimations and tabulations of shrub cover, ground cover, number of shrub and tree species, and number of individual trees within a 5 m radius of each station, soil hardness (with a soil penetrometer; Soiltest Inc., Chicaco, IL), and distance, diameter, and species of the nearest tree (> 7.2 cm dbh) within 5 m of the stations in each 90° quadrat."
