Cecropia is a genus of tropical tree that quickly grows in light gaps and often has some interesting relationships with symbiotic Azteca ants.  There are presumibly three species in Costa Rica, and two of the species are the subject of study for several students here with NAPIRE.  The third species (maybe) occurs at higher elevations, like at Las Alturas, and the group mentor, Cynthia Saugers, found several specimen.  We also came across an extremely large, but recently deceased, specimen here.  Most of the time, the diameter of these trees don’t get seem to get more than about 30 cm in diameter (at least from my glancing observations as an aquatic ecologist…).
