A Practical Guide for Ecological Restoration to Curb Biotic Invasion

Longleaf pine ecosystem restored through frequent application of prescribed fire to maintain native plants and discourage biotic invaders. Snapshot : Current restoration programs include both conservation and economic goals. To achieve both, restoration must curb biotic invasions, even under ongoing climate change, and mitigate contined human disturbance. Management actions need to include realistic goal-setting and more inclusive communication with broad, diverse audiences.

Summary

Biotic invasions are costly. USDA Forest Service scientists at the agency's Southern Research Station and cooperators reviewed the literature to identify common, feasible ecological practices that can help ecosystems resist new invasions and suppress the dominance of existing invasive species. Common practices for invasive species control and management include physical, chemical, and biological approaches. The biological approach includes biocontrol and the ecological approach. Each approach has limitations, but the ecological approach may be the safest and most practical choice. This practice has two major components: (1) restoration of native plant species that requires well-planned and implemented planting designs that consider diversity and the abundance of native and invasive species at local, landscape, and regional levels; and (2) management of the restored community to achieve and maintain viable populations. Management tools may include prescribed burning, grazing, harvesting, and thinning. The literature review focuses on the last decade and examines ecological approaches that involve biodiversity, biomass, and productivity, which are three key ecosystem variables that reciprocally influence one another. The scientists conclude that, because of the strong influence from exotic species pools in neighboring areas, local restoration and management efforts would benefit from considering the regional context and projected climate changes.
