Fire and Ecosystem Effects Interactions
How do spatial and landscape patterns of fire relate to tree mortality, survivorship, and turnover?
The importance of small fire refugia in the central Sierra Nevada, California, USA
Small fire refugia occurred on all landscape positions and within areas burned at all burn severity classes. Individual patches were not significantly related to burn severity, and the authors suggest that refugia may arise within high or low severity burned areas due to different reasons, such as fuel continuity or changes in weather conditions during the fire. However, the authors did find that the amount and distance between refugia decreased with increasing burn severity.

Spatially and temporally variable fire regime on Rincon Peak, Arizona, USA
The author’s findings suggest that isolated sky island ponderosa pine forests may be especially susceptible to climate change and drought because of their separation from the larger landscape and the frequent fire regimes that regulate severity in these ecosystems.
