Ecology and Silviculture of Northern Lake States Forests Research Focus

 

[image:] This figure shows the spectrum model of landscape management.  With the spectrum model, a landscape contains intensive production forests, colored yellow in the figure, and ecological reserves, colored blue in the figure.  These conditions are embedded within a forest matrix that is managed in various ways to conserve biological diversity and manage for timber, such that the matrix color grades from blue to yellow.

Spectrum Model of landscape management.

We use a spectrum model of forest landscape allocation as an organizing framework for our research. With the spectrum model (Palik and Levy 2004), fiber production and reserve forests are embedded within a matrix managed for integration of ecological and production goals. Some portions of the matrix are managed in similar ways to production forests (closer to yellow on the spectrum) and some portions are managed to favor goals and conditions similar to reserve forests (closer to blue on the spectrum), with a wide array (spectrum) of options for balancing ecological and production objectives between the endpoints.

Much of our research examines questions related to forest management in the matrix, as well as larger scale questions about landscape pattern and response to management. Major themes of our research include:

bulleted itemManagement approaches for sustaining ecological and production objectives

bulleted itemModeling landscape responses to management scenarios 

bulleted itemLong-term silvicultural studies
