Tertiary Vegetation History: Sierra Nevada Ecosystem Project

Abstract or Long Description:

From this report:

"An important message for ecosystem management from a study of the Tertiary flora of the Sierra Nevada is that, although vegetation has changed drastically over 65 million years, the rate has been very slow. Human impacts in the Sierra are potentially of a similar magnitude to these evolutionary changes but can occur at rates many times faster; such changes may be more rapid than plants are likely able to."

"The most appropriate management action is to maintain diverse, healthy forests with conditions favoring resilience to unpredictable but changing future climates and management regimes. Plans that require landscapes to reach precise vegetation targets are likely to fail. Management programs that build flexibility, reversibility, and alternative pathways are more likely to succeed in an uncertain future."
