Conifers

Most of Lassen Volcanic National Park is forested, with the distribution of conifers affected by elevation.

Red Fir Forest
Scattered throughout the park's forested areas are stands of old growth red fir, the characteristic tree in the red fir forest community. Growing to heights of over 175 feet, with diameters of 30 to 50 inches, these magnificent trees can live more than 300 years. The area surrounding the Kohm Yah-mah-nee Visitor Center, including the Mill Creek trail, is a good example of red fir forest in the park.

Whitebark Pine
These picturesque and hardy trees thrive in the subalpine habitats of the park.

Aspen

Lassen is home to a few species of deciduous trees, including quaking aspen and cottonwood. Both species can be seen at the Hat Creek and Devastated Areas. The suppression of forest fires has led to natural succession replacing aspen with conifers and vegetation. Aspen groves need fire or other disturbance to stimulate sprouting and control conifers which encroach on aspen groves. Read about aspen regeneration in the wake of the 2012 Reading Fire.
