Recommended Tree List

D.01 Tree Species Recommendation

This list is provided as a guide to the most appropriate species for tree plantings in urban areas. There is no single perfect tree; the most successful course is to match the planting site limitations with the right tree for that spot. Each site must be evaluated and possible restrictions of tree species noted. These restrictions include rooting space, soil texture, soil pH, drainage, exposure, overhead wires and surrounding building surfaces.

The trees appearing on this list have different requirements and tolerances. All of these species should do well in the urban forest environment of Carmel. Before selecting any particular species or variety further research should be done to ensure that the site would satisfy the specific requirements of the tree. Some of the species or cultivars listed here shall not be readily available at local nurseries, particularly in calipers large enough for planting in high traffic areas. Tree staking may provide limited protection.
