Mechanism
The transition from the Grassland State (1) to the Woody Complex (2) is driven by the lack of water in the shallow depressions. If conditions are right, woody species can germinate and grow simultaneously within the extent of the ecological site and create mottes of trees that grow with, but do not greatly affect, the herbaceous plant community.
Mechanism
Land managers may want to restore this ecological site to the Grassland State (1). Once in the Woody Complex (2) mechanical or chemical brush control is usually necessary to remove the trees from the plant community. The Lakebed ecological site naturally controls woody species; if the ecological site has standing water for a long period of time the subsoil is totally saturated and tree mortality will occur because of the anaerobic conditions in the root zone.
