Soil samples taken in autumn 1988 in a midslope position at 750 m a.s.!. on the north-facing slope of the Torrent de la Mina catchment. (From D. Bonilla.)
b Soil samples taken in each
of 6 plots at 550 m a.s.l. on a NW-facing slope on phyllites and schists. Four individual samples per plot, composited per plot.
