This is accomplished in a variety of ways. On some areas, natural forces are allowed to shape the plant and animal communities without intervention. However, correcting the results of human influences and disturbances often requires active management. On several natural areas including prairies, glades, savannas, and woodlands, fire, herbicides, and selective cutting are used to manage and restore natural communities. Exotic species eradication, water level manipulation, and providing adequate buffer land are other management methods used in natural area maintenance and restoration.
Most natural areas are open for public visitation and study.
All natural features are protected, and only foot traffic is permitted within these areas. Other restrictions may be posted on some natural areas. Contact area managers for regulations. The Missouri Natural Areas System has made a good start toward preserving the natural features of the state, but much work remains to be done. Many terrestrial and aquatic natural communities in several natural divisions and sections of the state are still not well represented.
