| Abstract: | The objectives of this study were to evaluate the allelopathic effects of Chinese privet (Ligustrum sinense Lour.) extract on native seeds and cuttings and to assess the survivability of native plants in a flooded riparian corridor. Field sites occupied the Trinity River floodplain in southeast Dallas County, Texas. Eight native species were evaluated. They were soapberry, red mulberry, persimmon, elderberry, beautyberry, coralberry, mustang grape, and heartleaf peppervine. From this study, we concluded that: - Truncating privet at ground level and applying equal parts of glyphosate and water to the stump effectively kills the plant;
- Once removed, privet does not curtail establishment of native plants;
- A 60‐day (d) flood killed most plants, with red mulberry being the most resilient;
- A 1% leaf and berry extract from privet significantly reduced soapberry seed germination; and
- A 1% extract from various parts of privet did not significantly affect root growth from cuttings.
