This transition is caused by an intentional clearing of land or a major disturbance such as a stand replacing fire or major flood in state 1, followed by intense, frequent disturbance such as grazing, mowing, crop production, or frequent fire to prevent trees from re-establishing. This transition can be initiated from any community phase in state 1. Disruption of the hydrologic regime by ditching and draining the site or building levies may or may not occur.
This restoration occurs by artificial or natural re-establishment over time of species resembling overstory and understory diversity typical of the reference state. This transition can be initiated from any community phase in state 2. If the hydrologic regime is intact and flooding can occur regularly, allowing the site to naturally regenerate to shrubs and forest is usually all that is needed. In some cases, treatment of invasive species such as Himalayan blackberry may improve the rate of restoration. If levies or drainage ditches interrupt the hydrologic disturbance process, then removal of ditches, water control structure and levies will be required to restore the reference state.
