Here's what past course participants have to say

L&A Equipment

Ora Ramage

“The workshop was very interesting and full of useful information. I was surprised at how much I learned! The course instruction and materials provided were relevant and applicable to our industry. I recommend this course to anyone in the site development, earthmoving, or excavating business.”

Whistler Blackcomb Landscaping


"We found the training very informative as always. Breanne did a great job and was very knowledgeable. We have removed invasives on a bunch of occasions and are always identifying new ones. We stopped some contractors from digging up a bunch of knotweed until we could advise them the proper disposal methods and provided them with bags and tags. We have also written to the Pemby Valley Nurseries about removing invasive lamium from our hanging baskets. We are all very aware of the problematic invasives in the area and always check we are not planting invasives."

Wildside Landscaping


"It was a great program and Breanne did a good job. I’d like more of my staff to participate next time."

Green Admiral Nature Restoration

Richard Beard

"I have no hesitation in saying that the course was excellent and provided amazing value for money. There is always something new to learn about dealing with invasive plants because we are dealing with a very dynamic Phenomenon. This course was up-to-date, had good visual presentation and the course materials for reference were outstanding. This is exactly the sort of information that should be widely circulated to inform anyone who is connected with landscaping, construction, biological restoration, or real estate. The course focused on practical ways of identifying and dealing with invasive plants in our local community. I could take what I learnt and apply it in the field immediately."
