Diversity is very important to the creation and maintenance of a healthy urban forest. For many years folks in the Midwest planted row upon row of elm trees to line residential streets. Apparently, people desired uniformity the trees were magnificent until the Dutch elm disease hit wiping out millions of elms around the country. Later, ash trees were the species of choice for many housing developments in our country. Then the emerald ash borer found its way to America and now many trees in our country are dying. Arborists (usually not an alarmist group) warn that it’s only a matter of time before the borer finds its way to Alamosa.
Planting a diversity of species reduces the chances of all trees in an area being infected by a debilitating pest. Also, different trees grow and age at different rates. If you plant a variety, you can replace a small portion of the trees when needed, not the entire park or street.
