Pseudotsuga menziesii, NM Lincoln (Douglas Fir (NM Lincoln)) is a species of coniferous tree that belongs to the Pinaceae family. The specific variety "NM Lincoln" refers to a cultivated variety or a location-specific variant of Douglas Fir found in New Mexico, particularly in the Lincoln National Forest or the surrounding area.
Douglas Fir trees are native to western North America, and they are widely distributed throughout the region. They are known for their impressive size, reaching heights of up to 200 feet (60 meters) or more, making them one of the tallest tree species in North America. The trunk can have a diameter of several feet, and the tree forms a broadly conical shape.
The foliage of Pseudotsuga menziesii is evergreen, consisting of flat, needle-like leaves that are arranged spirally around the branches. The needles are dark green on the upper side and have a lighter tone on the underside. They give off a pleasant aroma when crushed. The needles are typically around 1 to 1.5 inches (2.5 to 3.8 centimeters) long.
One of the distinctive features of Douglas Fir is its large, cylindrical cones. These cones measure around 2 to 4 inches (5 to 10 centimeters) long and have three-pointed bracts that extend beyond the scales. The cones hang downward from the branches and eventually release their seeds, which are dispersed by the wind.
In terms of habitat, Douglas Fir trees are adaptable and can thrive in various environments. They are commonly found in mountainous regions, including forests and woodlands. They prefer moist, well-drained soils but can tolerate a range of soil conditions. They are also relatively tolerant of shade, although they typically grow best in full sunlight.
Douglas Fir is highly valued for its wood, which is strong, durable, and widely used in construction, as well as for making furniture, flooring, and other wood products. The tree also provides important habitat for various wildlife species and contributes to the overall biodiversity of forest ecosystems.
In summary, Pseudotsuga menziesii 'NM Lincoln' refers to a cultivated variety or a variant of Douglas Fir found in the Lincoln National Forest in New Mexico. It is a majestic evergreen tree with tall stature, dark green needles, and large cones, and it plays a significant ecological and economic role in its natural range.
