252 Symposium--Soil Mechanisms Controlling Forest Responses to Management and Environmental Change: 2

Oral Session
SSSA Division: Forest, Range & Wildland Soils
Soils are the hub of physical, chemical, and biological processes in forest ecosystems. A mechanistic understanding of how soil processes respond to changing environmental conditions is required in order to predict how forest ecosystems will function and respond to different management regimes and environmental change. We invite presentations that highlight processes in forest soils as they respond to changes in forest management (e.g., harvesting, fertilization, site preparation, long-term soil productivity) or other environmental changes (e.g., land use, global, climate, fire) and how those soil processes affect larger scale phenomena (e.g. tree and stand productivity, water quality, long-term soil productivity, biodiversity).
