California RPF Exam Questions andAnswers (Latest Update 2024)
1) Describe the effect of increased carbon dioxide on forest
growth. - Correct Answer ✅Increased CO2 can improve
photosynthesis efficiency and increase forest growth.
However heat associated with increased C02 may lead to
more extreme weather events causing more high intensity
fires.
2) List three (3) conditions that demonstrate forest
sustainability (note this is not simply sustained yield). -
Correct Answer ✅When management decision take into
