Trees and Shrubs
Most of Lassen Volcanic National Park is forested, with the distribution of conifers affected by elevation.
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.
Also scattered throughout the park are several small stands of quaking aspen.
