We selected a sample of thirty-one coffee agroforests// (herein also referred to as farms)// characterized by a wide range of farm sizes, ages, and elevations.// We adopted a sampling methodol-ogy employed in previous studies on floristic richness in Chiapas (Perez-Ferrera and Tejeda-Cruz, 2011//;, which consists of establishing one cir-cular plot composed of three concentric circles (radii of 5, 12, and 17 m) at the center of each farm//. We identified, counted, and mea-sured the diameter at breast height (DBH) of adult shade trees
