According to Anthony & Astorga (1997), the CATIE collection suffers the loss of some 250 individuals every year, which amounts to a general genetic erosion rate of 3% (4.8% for the wild genotypes). The expense of maintaining these collections, as well as the reticence of sponsors to finance such activities, are perhaps the most important factors affecting this erosion.
