Facts
The cone scales and sharp needles of pitch pine are thick and rigid, making this a distinctive and easy-to-remember species. In New England, it most commonly occurs in sandy barrens and coastal plains; it is the only moderately salt-tolerant pine species in the region. It relies on fire to clear areas of competitors and allow for colonization. This hardy species is extremely resilient to fire and herbivory by deer; it readily sends up new shoots in response to stress. Pine grosbeak, pine warbler, and many other birds find the seeds a welcome mid-winter food. The dense, resinous wood has long been used for ship-building and rough construction.
Habitat
Wetland margins (edges of wetlands), woodlands
New England distribution
Adapted from BONAP data
Native: indigenous.
Non-native: introduced (intentionally or unintentionally); has become naturalized.
County documented: documented to exist in the county by evidence (herbarium specimen, photograph). Also covers those considered historical (not seen in 20 years).
State documented: documented to exist in the state, but not documented to a county within the state. Also covers those considered historical (not seen in 20 years).
Note: when native and non-native populations both exist in a county, only native status is shown on the map.
