Management

Beneficial Management Practices:

Forest - control grazing of domestic livestock

Beneficial Management References: 004

Adverse Managment Practices:

Forest - application of herbicides

Adverse Management References: 004

Comments on Management:
Steyermark estimated that the erection of dams along the White River in Missouri has destroyed millions of plants by flooding several populations. Maintenance of habitat through conservation of the forest canopy under which tradescantia ozarkana occurs may be the most important management activity. Limited timbering may be beneficial or adverse depending on the amount taken. In general if there is no timber harvest, windthrow and mortality may be adequate in sustaining populations. Succession of habitat may threaten populations by shading out individuals through increased cover from tree canopies. Other threats include habitat destruction for development, roadway construction, timber harvest, and livestock pasturing *04*.
