Quercus buckleyi | Fort Collins

Few people were talking about climate change and species migration in 2006, when this photo was taken. But smart horticulturists anticipated this later development in ecology in their search for new trees. The Fort Collins arborist looked south, largely because there’s little choice when you’re in northern Colorado because not many oaks grow north of there. But attentive people have been seeing climate change coming for decades, and what little biological preparation we have now is often attributable to such people. Temperature zones are moving northward, largely, and moving the trees and other woody plants in anticipation of such climatic change is sometimes known as assisted migration. Even if that wasn’t why you did it. Some poor creature fleeing spiking temperatures to the south might just find a new home in the Texas Red Oaks of Fort Collins.
