In a hidden-away arroyo in Jalisco, botanists were amazed to see not just one maple tree but a whole woods full of them, an ancient fir-maple-conifer cloud forest.
In the late 1990s, Fernando Aragón Cruz, acting as a guide for bird researchers from the University of Albuquerque, collected a sample of a kind of sugar maple from a remote spot 50 kilometers southeast of Puerto Vallarta.
As few native maples had ever been found in western Mexico, local botanists were surprised. They were even more surprised when they went out to look at the site. In a hidden-away arroyo called El Refugio, at 1,764 meters altitude, they were amazed to see not just one maple tree but a whole woods full of them, incorporated into an ancient fir-maple-conifer cloud forest, incomparably rich in diverse species of trees and plants.
