#FunFactFriday: Did you know that trees can teach us about the past? Using dendrochronology (the study of tree rings) we can learn about climate, drought, fires, and other environmental changes throughout time. Narrow rings can mean dry years, while wider rings translate to wet years. By comparing trees and looking at these patterns, rather than number of rings, scientists can learn about specific time periods. Bristlecone pines, like the ones found in the Spring Mountains, can show us a very long environmental history as they live to be thousands of years old!
