Ecological Restoration
Ecological restoration is the effort to restore the total ecological complexity of woodlands.Â
Woodlands are defined as plant community covered by a tree canopy of at least 50 percent. On the ground beneath are many grasses, sedges, ferns and forbs. Most of these woodland plants are what are called spring ephemerals---beautiful, delicate, low growing plants whose annual growth cycle is necessarily compacted early in the spring when they can catch the light and energy coming through the overstory canopy before leaf out. Between the dominant overstory and the rich ground layer is a middle layer of shrubs and small trees that will eventually become the overstory if conditions become favorable.
Restoration is a slow process, usually beginning with eradicating a serious exotic plants that literally take over precious woodland acreage. Other challenges include the inability to use equipment in cramped quarters and the limited seed resource available to restorationists and ecologists. Interestingly, as with the other major plant communities, fire is an important tool for preparing and maintaining woodland sites.Â
