About the Species
\n<\/strong><\/span><\/p>\n

Douglas fir (Pseudotsuga menziesii)<\/i>\u00a0is an\u00a0evergreen\u00a0conifer\u00a0species\u00a0in the pine family,\u00a0Pinaceae<\/a>. It is\u00a0native\u00a0to western\u00a0North America\u00a0and is known as\u00a0Douglas-fir,\u00a0Oregon pine,\u00a0and\u00a0Columbian pine. <\/span><\/p>\n

The common name honors\u00a0David Douglas, a Scottish botanist and collector who first reported the extraordinary nature and potential of the species. The common name is misleading since it is not a true fir, i.e., not a member of the genus\u00a0Abies<\/i>. For this reason the name is often written as\u00a0Douglas-fir\u00a0(a name also used for the genus\u00a0Pseudotsuga<\/i>\u00a0as a whole).[9]<\/sup><\/span><\/a><\/span><\/p>\n

The specific epithet\u00a0menziesii<\/i>\u00a0is after\u00a0Archibald Menzies, a Scottish physician and rival\u00a0naturalist\u00a0to\u00a0David Douglas. Menzies first documented the tree on\u00a0Vancouver Island\u00a0in 1791. Colloquially, the species is also known simply as\u00a0Doug fir[6]<\/sup><\/span><\/a>\u00a0or\u00a0Douglas pine[6]<\/sup><\/span><\/a>\u00a0(although the latter common name may also refer to\u00a0Pinus douglasiana<\/i>).[10]<\/sup><\/span><\/a>\u00a0Other names for this tree have included\u00a0Oregon pine,[5]<\/sup><\/span><\/a>\u00a0British Columbian pine,[6]<\/sup><\/span><\/a>\u00a0Puget Sound pine,[6]<\/sup><\/span><\/a>\u00a0Douglas spruce,[6]<\/sup><\/span><\/a>\u00a0false hemlock,[5]<\/sup><\/span><\/a>\u00a0red fir,[5]<\/sup><\/span><\/a>\u00a0or\u00a0red pine[5]<\/sup><\/span><\/a>\u00a0(although again the latter may refer to a different tree species\u2014Pinus resinosa<\/i>).[11]<\/sup><\/span><\/a><\/span><\/p>\n

Douglas-firs are medium-size to extremely large evergreen trees, 70\u2013330 ft tall (although only coast Douglas-firs reach such great heights).[13]<\/sup><\/span><\/a>\u00a0The\u00a0leaves\u00a0are flat, soft, linear, <\/span>3<\/sup><\/span>\u2044<\/span>4<\/sub><\/span>\u20131 <\/span>1<\/sup><\/span>\u2044<\/span>2<\/sub><\/span>\u00a0in long, generally resembling those of the firs, occurring singly rather than in\u00a0fascicles; they completely encircle the branches, which can be useful in recognizing the species. As the trees grow taller in denser forest, they lose their lower branches, such that the foliage may start high off the ground. Douglas-firs in environments with more light may have branches much closer to the ground.<\/span><\/p>\n

The female\u00a0cones\u00a0are pendulous, with persistent scales, unlike those of true firs. They are distinctive in having a long tridentine (three-pointed)\u00a0bract\u00a0that protrudes prominently above each scale (it resembles the back half of a mouse, with two feet and a tail).<\/span><\/p>\n

Pseudotsuga menziesii<\/i>\u00a0var.\u00a0menziesii<\/i>, <\/span>the coast Douglas-fir, grows in the coastal regions from west-central\u00a0British Columbia<\/span><\/a>\u00a0southward to central\u00a0California. In\u00a0Oregon\u00a0and\u00a0Washington, its range is continuous from the eastern edge of the\u00a0Cascades<\/a>\u00a0west to the\u00a0Pacific Coast Ranges<\/a>\u00a0and Pacific Ocean.<\/span><\/p>\n
