Disturbance Ecology and Management of Oaks


The Northern Research Station has realigned our staff from 37 Research Work Units and Programs into 14 new Research Work Units.

RWU-4557 is now part of NRS-3, Ecology and Management of Invasive Species and Forest Ecosystems.

Our Mission

To provide methods for creating and maintaining healthy, sustainable oak-dominated forests based on a more complete understanding of ecological relationships, landscape ecology principles, silvicultural management, and gypsy moth population dynamics, and to incorporate this knowledge into management guidelines and decision support systems.


Our scientists are engaged in research on the: 1) dynamics of vegetation response to defoliation by gypsy moth and other established exotic organisms and interactions with other forms of disturbance; 2) population dynamics of gypsy moth and other introduced pests at landscape scales, including invasion spread dynamics and forest susceptibility and the use of that understanding to develop appropriate management decisions; 3) development of biologically and economically effective silvicultural treatments for rehabilitating and regenerating oak forests, especially regeneration failures due to severe gypsy moth mortality and oak decline; and 4) synthesis and integration of results from studies of disturbance effects and dynamics into models for decision support systems and applications to management. We also are refining silvicultural practices for reducing gypsy moth effects and transferring this technology to users.

Proposals Funded

To Conduct Research on Biological Invasions in Northeastern and Midwestern Forests

NRS-4557, Disturbance Ecology and Management of Oak-Dominated Forests selected seven proposals to fund for research on non-native species biology, ecology, and management. The supported research focuses on biological invasions of non-native species in Northeastern and Midwestern forests; non-native pest insects, pathogens, and plants that result in serious or potentially serious economic or ecological effects. View funded proposals.

Funded Proposals documentation is in PDF format. You can obtain a free PDF reader from Adobe.

More Information

This site is under development as the Forest Service brings together the Northeastern and North Central Research Stations to form the Northern Research Station, serving the Northeast and Midwest. Check back often as we expand our site to reflect our combined commitment to supporting the natural resources and people of the Northeastern and Midwestern United States.

The Stand-Damage Model simulates the growth of individual trees within forest stands. The user can change much about the forest and its environment: the location of the forest, its weather and soil, and the trees at the beginning of the simulation. One can try different logging practices and introduce global warming temperature changes. You can grow your own forest stand and graph the results.
