Forest site classification adapted to the respective site conditions is one prerequisite for<br/> sustainable silviculture. This work aims to initiate the forest site classification for pine plantations<br/> in the southern Andean region of Ecuador. Forest productivity, estimated by the dominant height<br/> of 20-year-old trees (DH20), was related to data from climate, topography, and soil using 23 plots<br/> installed in pine plantations in the province of Loja. Forest site productivity was classified as:<br/> low (class C: 13.4 m), middle (class B: 16.6 m), and high (Class A: 22.3 m). Strong determinants<br/> to differentiate the forest site classes were: the short to medium term available Ca and K stocks<br/> (organic layer + mineral soil standardized to a depth of 60 cm), soil acidity, the C:N ratio, clay and<br/> sand content, forest floor thickness, altitude, and slope. The lowest forest productivity (Class C)<br/> is mainly associated with the lowest short to medium term available K and Ca stocks. Whereas,<br/> in site classes with the highest forest productivity, pines could benefit from a more active microbial<br/> community releasing N and P, since the soil pH was about 1 unit less acidic. This is supported by the<br/> lowest forest floor thickness and the narrowest C:N ratio.
