Zone 2 . Predominant vegetation in Zone 2 should also consist of species selected for their ability to stabilize the riparian area. If the riparian system has been dominated by tree species historically, then trees should be planted in Zone 2. Deciduous tree species are important as sources of leaf litter and carbon. Evergreens, however, take up nutrients in winter months, protecting water quality throughout the year.
Native species are preferred.
Check with the Oklahoma Department of Agriculture - Forestry Division, NRCS, or U.S. Fish and Wildlife Service for species recommendations if timber, wildlife, or other benefits are desired. To maximize nutrient uptake, dense perennial grasses and forbs are recommended. Vegetation should be maintained in a vigorous growth condition, unless this conflicts with wildlife management objectives. Select species adapted to site conditions considering other benefits, such as forage production and wildlife habitat improvement. Not all species listed are adapted for statewide planting.
