The importance of trees to our ecosystem cannot be overstated. As prodigious producers of oxygen, trees contribute to our environment’s ability to sustain animal life. Over the years, people have found many other uses for trees, including shade, recreation, and ornamentation. And of course, we also use their wood to build homes and furniture. One way to start becoming proficient at spotting different types of trees is to use dichotomous keys, or features that split the population in two. A common dichotomous key for trees is deciduous vs. coniferous. Deciduous trees produce leaves in the spring, which they lose in autumn and winter. Coniferous (cone-bearing) trees, on the other hand, maintain their needles year-round. You can narrow down your search for a particular tree species by knowing which areas it’s likely to grow in. The United States is divided into 11 areas called hardiness zones, which give some insight into which trees are likely to do well locally. We can also study a tree’s leaves, bark, and wood for additional help in identification. Identifying trees can be an interesting pastime, and it’s also a deceptively challenging activity. Trees have a high degree of variability, but some species have just enough in common to fool our eyes. By researching each species and its individual traits, however, we can learn to confidently and accurately identify different types of trees.
