Kudzu Spreads North

Kudzu, a problematic vine, has spread from the southern US to the north and Canada, largely due to climate change. Originally planted for soil erosion control, it now poses ecological threats by dominating other species and hosting soybean rust. Effective management includes physical removal, mowing, and using goats. Research also explores kudzu's potential as a biofuel.
