Invasive invaders: Japanese knotweed and non-native species in our homes
Abstract
This paper dives into the intriguing discussions of Japanese knotweed and other invasive non-native plants, how they affect our built environment, and the legal ramifications for allowing these plants to spread beyond the realms of confinement. The paper sheds light on historical misinformation and begin to establish a nuanced understanding towards a plant which is surrounded in hysteria. In an attempt to unravel the cause of this hysteria, the paper describes a well-known plant which is five times more likely to causes structural issues to a property. The paper also highlights the presence of another plant which has striking similarities to Japanese knotweed; however, the paper advises caution in avoiding exacerbating even more unnecessary hysteria. The paper highlights building professionals’ potential ignorance of other invasive species beyond Japanese knotweed and the impacts they could cause. The paper aims to equip readers with insights into legal complexities, debunk myths surrounding invasive non-native plants but bring to light new emerging threats. It advocates for a comprehensive risk assessment approach, fostering a nuanced understanding of the impacts of various invasive species.
