Actually in the Oak Forests of the Talamanca range in Costa Rica, we get exactly this same thing at the same altitudes, only the trees are over 50 meters tall. Either the author of this piece incorrectly reported the altitudes from the original publication, or the the authors of the original article did not do a thorough literature search, because tall forests are also found at these altitudes throughout the Andes Mountains. It is true that certain criteria seem to be necessary, because at only about 1,800 meters in the Monteverde Cloud Forest in Costa Rica's Tilaran Mountains, you start to get elfin forests. I suspect this has more to do with factors such as wind speed, precipitation, humidity, and being on a ridge top, than with altitude alone. Anyway, I will have to get my hands on the original article to know what was actually reported, as synopses written for the general public often get it wrong.
