Selecting the right tree for the right place is very important in order to avoid loss of trees by insects, disease or environmental factors. Every place has its unique characteristics and not every tree is adequate for a determined place. Another important fact to know is that a single species of trees shouldn’t represent more than 10-15 percent of a community’s total tree population, so it is important to plant different tree species.

There are certain tree species that are not recommended in Colorado because of brittle wood, susceptibility to insects and diseases, or their ability to spread into native ecosystems and out-compete native species, while others simply do not grow well in our climate.
