Last fall KDFWR private lands program funded experimental drone flights spraying invasive kudzu patches on 8 pieces of private property over 6 counties totaling 100 acres. As we are now actively in the growing season for kudzu, we revisited these sites to assess progress made.
We are really excited about the coverage and treatment of these areas to this point. We significantly set this invasive back with our applications. Achieving, at this point 90-95% control in some patches. Even more exciting is the native vegetative response in these patches. By doing this treatment we have released elderberry, dogbane, geranium, perennial ryegrass, yellow buckeye, ironweed, wingstem, pokeweed, common milkweed, and ragweed among many others. Also, we prevented to this point, in having any negative effects on trees within the units and outside.
Additionally, wildlife continue to utilize these areas. A suite of songbirds including towhee, tree swallow, yellow breasted chat, cardinal, wren, wood thrush, sparrows, indigo buntings, cedar waxwings among others have been identified in the patches. We have also seen white tailed deer, chipmunks, black rat snake, and cottontail rabbits running/slithering through the sections.
Although we do recognize this isn’t a silver bullet. Kudzu has persisted in these areas especially along the edges we couldn’t spray. Follow up treatments will be required for years to achieve eradication. But we do believe at this point this is a viable tool in the toolbox for control of this overwhelming invasive species to native diversity.
We will keep you updated on this project as we progress through the growing season and determine the next steps.
Below are before and after pictures of some of the different sites.
