174 Table A5-7. Principal component loadings (PC1, PC2 and PC3) calculated on the ecosystem service indicators. Green shading indicates positive relations ( > 0.30), red shading indicates negative relations ( < -0.30). Divided in time slots 1-10 and 11-20 years after transition to agroforestry.

Principal component analysis on ecosystem service indicators. AGCtot is above-ground carbon, BGC is below-ground carbon, Litter is litter cover on the soil, HerbCov, is understory vegetation cover, Erosion.ctr is control of potential soil loss, Slake is soil stability, Epiphyte is epiphyte group presence, Brocca is coffee berry borer control, YieldAv is coffee yield, CofQuality is coffee quality. Colors indicate time since transition (TSA.class) with light yellow younger farms and danker brown older farms.
