Recommended Trees
The Cape Cod Commission has published a list of trees encouraged for planting on the Outer Cape. The list is extensive and user-friendly; it groups the trees by height and width at maturity, making it an ideal resource for tree selection and placement. The list appears at pp. 45-65 of the Route 6A Vegetation Management Plan, Cape Cod Commission (1995). The listing of the trees by common and scientific names is immediately below. These are all acceptable for planting in Provincetown with the few exceptions noted in red. For additional information and specific characteristics go to http://www.capecodcommission.org/resources/transportation/Route6A/Vegetation_MP_1995.pdf

Trees indicated in red have been removed from the 1995 list as not acceptable for planting in Provincetown, either because they’ve been overplanted in town or banned in the Commonwealth.
Another list of trees acceptable for planting in Provincetown, titled Trees & Shrubs for Coastal Environments, is published by the Cape Cod Cooperative Extension, located in Barnstable. Plants on this list were selected based on their ability to grow in coarse soils and windy environments, and for salt spray tolerance. To download the document, go to

Vulnerable Trees. A word of caution: The lists published by the Cape Cod Commission and the Cape Cod Cooperative Extension include trees known to be hosts to the Asian longhorned beetle (“ALB”) and the emerald ash borer (“EAB”), two insects that kill trees. These insects have attacked, and killed, hundreds of millions of trees in the United States. So far (as of this writing in 2017) neither insect has been detected on Cape Cod. When planting trees in Provincetown, you may want to consider planting trees that these insects do not prefer. The ALB prefers maple species (Acer), including boxelder, red, silver, and sugar maples. Other preferred hosts are birches, Ohio buckeye, elms, horsechestnut, and willows. The EAB attacks only ash trees (Fraxinus).
An insect that has been detected on Cape Cod is the Southern pine beetle (SPB), which infests pine trees. All pine trees are susceptible, including pitch pine, white pine, and red pine. In addition to pines, hemlocks and spruce may also be affected in highly infested areas. Pitch pine is a dominant tree on Cape Cod. So far, the SPB has been found in traps on the Cape but not in trees.
Stay alert to local and state regulations for insect pest control that may be issued after the date of this writing.
