Produce coffee in shaded plantations
A paired sites, site comparison in 1998 in seven areas of shaded coffee plantation and forest in Chiapas, Mexico (Mas and Dietsch 2004) found that a plantation with the original canopy retained and understory replaced with coffee (“rustic” management) had higher species richness of fruit-eating butterflies than a plantation with its original canopy retained and understory replaced with coffee and other vegetation (“traditional polyculture”) or plantations with their original canopies replaced with other shading trees and understories replaced with coffee with (“commercial polyculture”) or without other vegetation (“shaded monoculture”). The rustic plantation had higher species richness of fruit-eating butterflies (25) than traditional polyculture (10), commercial polyculture (10–11) and shaded monoculture (10) plantations. The rustic plantation had similar species richness to a nearby intact area of forest (27) but lower species richness than a further away forest (36). In two areas of Mexico, one rustic, one traditional polyculture, one shaded monoculture and two traditional polyculture plantations were surveyed. In summer 1998 at four points in each location (28 points in total) two fruit-baited traps were set, one in the understory and one in the canopy, for eight days. Estimated species richness was calculated statistically from numbers of butterflies caught in traps.
