| Research Interests: |
| Research in Forest Ecophysiology is directed toward improving our understanding of the effects of environmental stress on tree and forest stand productivity. Projects are investigating how water stress and soil nutrient deficiencies effect tree growth and wood formation.
As a part of this research, work is being conducted to quantify physiological responses of forests to silvicultural practices, including thinning, fertilization, and competition control. Measured response variables include tree water relations, photosynthesis and respiration, leaf area dynamics, soil microbes, and wood properties. It is expected that an improved understanding of environmental stress physiology will lead to the development of forest management practices to increase forest productivity and sustain forest ecosystems. Research is also being conducted in Urban Forestry, including new uses of GIS technology to improve the management of forests in our communities. |
