Current Sponsored Projects
- Examining the lasting effects of land management on forest soil health
Forest management techniques affect the ecosystem on a myriad of time scales. This project explores the influence of different harvest strategies ten years after implementation at a long-term ecological productivity study site in northern Oregon. Understanding how silvicultural practices change the environment will shine a light on balancing the sustainable use of forestry products with ecosystem productivity.
- Relationships between soil chemistry, microclimate, and Pinus ponderosa growth
We are examining the possible origins of noise in tree rings, isotopes, and dendrometer-based increment growth based on differences in soil microclimate, nutrient status, and soil water availability. Initially, we are focusing on Washington State, with plans to later expand this study across the range of PIPO in the western United States.
