Plan to introduce Japanese Knotweed predator


The introduction of an alien species from Japan to combat an existing problem is a potentially dangerous solution albeit a cheaper solution than existing herbicide controls for Japanese Knotweed. The possible impact this alien insect will have upon the native flora and fauna is as yet unknown and may not become apparent for several years after its introduction. There is well documented evidence to suggest that irreparable and uncontrollable damage can be done to our native species on the introduction of alien species both in animal and plant life. I strongly urge the government not to take this route but to further explore additional herbicide controls. I am extremely concerned that this insect will displace existing native insects which may in turn have disastrous consequences along the food chain. or it may turn it's attention to other road/river side plants thereby upsetting an entire and often fragile ecological system.
