English: Photograph by Dirk van der Made (User:DirkvdM - for more photos see user:DirkvdM/Photographs). Coffee plantation with shade trees in Orosi, Costa Rica, 1 February, 2004. Coffee in Orosi is grown in the shade during parts of the growing season, which is supposed to improve quality. The red trees in the background provide shade. The predominant shade tree here is poró (Erythrina poeppigiana); those in the foreground have been pruned to allow full exposure to the sun.
