Pseudotsuga menziesii — coast Douglas-fir

Facts
Coast Douglas-fir refers to the west coast, as this species naturally ranges from British Columbia south to California. However, many have attempted to grow the majestic Douglas fir east of its natural range, due to its beauty and its importance as a timber tree. Although it only typically grows to 80 feet (25 m) in cultivation, mature trees in Pacific rain forests attain towering heights of 300 feet (100 m). The fragrant needles have white "racing stripes" on the undersides. In New England, this species has only naturalized in damp forests (reminiscent of its wet habitats in the northwest) in Connecticut.

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.
