SelecTree, a tree selection guide, is an interactive program designed to help you select appropriate trees. It will match trees to particular sites based on compatible characteristics. Lists of trees generated by SelecTree should be viewed as a guide, not as the final authority in a tree search. SelecTree is maintained by the Urban Forest Ecosystems Institute at Cal Poly State University, San Luis Obispo.
Proper planting techniques to assure healthy root systems.
Although designed for a California town, these guidelines can readily be adapted for your community.
Crowding has a negative effect — too much competition for too few resources — and kills smaller trees among stands of larger trees. Examining your own forests for “crowding” may suggest where trees are stressed, and hence more susceptible to insects and pathogens.
Sites with saline (salty) soils, and those that are exposed to coastal salt spray or de-icing materials challenge tree health, and ultimately those responsible for the tree. This article presents guidelines for planting in salt-compromised sites, and lists saline-resistant species for the mid-Atlantic.
Evergreen trees can be used to reduce wind speed and thus loss of heat from your home in the winter by as much as 10 to 50 percent. Trees absorb and block noise and reduce glare. A well placed tree can reduce noise by as much as 40 percent.
