A brief description of the IPM program:

The 23 acres of grounds use chemical control as the last resort. We have visual thresholds and monitor fungal and insect pest damage. We try to maintain healthy plants with limited excess nutrient availability. Only in situations where weather or density will not control an issue do we use chemical control to prevent loss of turf.

The 700 acres of the Green Oaks Biological field station includes a restored prairie that is burned annually, as well as old-growth and new-growth forests that are managed for biodiversity. The director assess the site. In places where there is encroachment by woody invasives - primarily autumn olive, amur and other non-native honeysuckles, Japanese barberry, multiflora rose, and black locust - the small trees and shrubs are cut down and herbicide is applied to the cut stump.
