Oak Savanna Restoration: Diversity in a Rotational Grazing System
Hundreds of landowners along the Des Moines River Valley are experiencing loss of oak savanna habitat to shallow-root grass pastures. Consequently, soil erosion and lower water quality occur.
Objective: To restore two and one-half acres of permanent pasture to oak savanna for rotational grazing.
The producer used Roundup to eliminate warm-season and native grass species, as well as red cedar, inhabitating the area. The area was then planted with cool-season grass species, especially bluegrass and brome.
Results: Restored shrubs include White Oak, Red Oak, Hickory and Elm. The project was extended due to drought.
