Does Seeding a Locally Adapted Native Mixture Inhibit Ingress by Exotic Plants

摘要: Non-native plant species often colonize retired agricultural lands, creating monocultures with low diversity that provide poor wildlife habitat. We assessed whether sowing a mix of 29 locally adapted native reduced invasion non-native compared to allowing vegetation naturally following tillage. There was sampling date × treatment interaction for canopy cover perennial exotic species. Plots were not sown natives had two six times greater than did plots both preparation (woody removed, plowed, and disked) control (no or sowing) plots. Canopy plants similar in prepared-only treatments from October 2008 June 2010, ranging 8 40%. Percent absolute 10–20 on prepared planted during March 2009 2010. Sowing may inhibit encroachment by up years after land the Lower Rio Grande Valley Texas.
