Emily from Environet delivered a very interesting CPD session for my team where we all learnt more than we expected to. As ecologists we are used to identifying Japanese Knotweed on sites but we weren’t familiar with the methods a client needs to undertake to rid themselves of the problem or the potential knock on effects to other species. The session was very well delivered in an informal manner by a fun yet knowledgeable presenter. I’d recommend this CPD session to other ecologists and other relevant disciplines.

Many thanks for attending our AGM the other week, all of our surveyors found your talk very informative. The presentation was very comprehensive and really helped us learn more about Japanese knotweed, particularly identification techniques. We have had several speakers on this topic over the years but yours really was one of the better ones as you focused more on the identification throughout the year, problems associated with the plant and remediation. Once again thank you for your time.
