Natural Resource Condition Assessment for Sequoia and Kings Canyon National Parks. Appendix 21. Altered Fire Regimes.

摘要

Given the importance of fire in the SEKI landscape, we characterize both the temporal and spatial trends in fire extent, frequency, and severity. Here we focus on fire’s role as stressor since alterations to the fire regime can impact multiple focal natural resources. Specifically we ask: 1. What is the contemporary fire history of SEKI (1917-2010)? 2. How much does the current frequency and extent of fire vary from the pre-settlement fire regime? 3. How does the current fire hazard vary across the landscape? 4. What are the projected trends in wildfire risk for SEKI with a changing climate?
