The California Phenology Project (CPP) was launched in 2010 as a three year pilot program to create long term monitoring and public education activities throughout California. As a part of the CPP, Sequoia National Park monitors four plant species within the park. Data is collected regularly and entered into the National Phenology Network (NPN) database.

Around the Foothill Visitor Center, park staff and volunteers monitor blue oak and California buckeye. In the Giant Forest, greenleaf manzanita and mountain pride is monitored. Weather stations at each monitoring site provide site-specific climate data, which can be compared to variation in phenological observations.

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.
