Management approaches for sustaining
ecological and production objectives
Traditional approaches to forest management, while often achieving
desired, short-term timber objectives, may inadvertently predispose
stands to invasion by exotic plants. Longer-term outcomes of invasion
could include reduced establishment, survival, and growth of desired
timber species, as well as broader negative impacts to native plant
The potential for stand-scale management to predispose forest for
invasion must be addressed in a
landscape context. Certain landscape factors, such as adjacent landuse, road
densities, patch sizes and shape, may have an equal or greater
influence as within stand management on probability of invasion.
We are addressing these issues in the context of oak management and
invasion by exotic shrubs in south eastern Minnesota.
We have ongoing research on...
