Species to Species: Not All Trees Created Equal
by Micah Pace, Director of Consulting, ISA Certified Arborist TX-3752 and Registered Consulting Arborist #607
Micah recently discovered similar but different tree species growing near each other on a local landscape. The details tell the story.
Not all trees are created equal and offer the same benefits, even if they may appear very similar. Being able to distinguish between two closely linked species is important from an ecological and maintenance standpoint. The image below depicts two elm branches taken off trees on the same property in a Dallas neighborhood.
The top branch is from a Siberian elm (Ulmus pumila) while the lower branch is that of an American elm (Ulmus americana). Understanding the differences between species of the same genus is an important component of professional tree management. Some species, while quite similar in appearance, or even habit, can provide a very different environmental impact, and thus require different management recommendations.
American elm is one of the beloved and iconic species in the United States, particular in the eastern part of the county. However, Siberian elm, as you might have guessed, is not native to the U.S. In fact, according to the TexasInvasives.org website, it is categorized as an invasive exotic plant in Texas (as well as many other states) for its aggressive seedling habit that allows it to out-compete many native plants. This aggressive habit ultimately changes the ecological relationship between plants and animals in the landscape.
