As I understand it, as long as the japanese knotweed is retained on the site, it isn't illegal to move it around the site.
However, as the site clearance is in preparation for a development that hasn't yet got planning permission, I am very surprised that the enforcement team seems to think this isn't a problem.
This certainly needs chased up, especially as you have a plant species list available, as evidence of the ecological value of the site.
As suggested Natural England, and local Planning Authority both need written complaints, and the Environment Agency informed about the Jap Knotweed,because a company who seems to have started their development work before getting planning permission may also be a company who feels they can disregard the law as regards jap knotweed.
