Fire Scar Images

Fire record from mid-elevation xeric conifer forest (primarily Jeffrey pine). Fire return intervals in this forest type usually range between 20-50 years (average of about 30 years) on the west slope of the Sierra Nevada.

Long interval fire frequency regime from an upper elevation forest composed of red fir, western white pine, and small amounts of lodgepole pine. Fires are typically understory burns in red fir forest although small-to-moderate sized patches of overstory mortality can occur.

Red fir trees are moderately tolerant of low intensity fire with larger trees having fairly thick fire resistant bark. In contrast, both western white and lodgepole pine have relatively thin bark that provides poor protection from fire. Thus they gernerally suffer proportionally higher mortality rates than red fir.

Did You Know?

Sharp, rocky crest of the Sierra Nevada.

The Sierra Nevada is still growing today. The mountains gain height during earthquakes on the east side of the range. But the mountains are being shortened by erosion almost as quickly as they grow. This erosion has deposited sediments thousands of feet thick on the floor of the San Joaquin Valley.
