Our guest will be Michael Mesure, a founding member and Executive Director of Fatal Light Awareness Program (FLAP) Canada. Michael will speak about the work of FLAP Canada, how human-made structures threaten birds and offer solutions for mitigating building collisions. This will include examples of both effective and ineffective collision deterrent methods and some background on bird-friendly building design guidelines, policies, code and law. We hope you can join us!

Many invasive plants cannot be used by wildlife for food which puts grazing pressure on the few native plants that remain. Invasive plants also pose threats to agriculture due to their ability to spread quickly, out-compete crop and forest plants, and deteriorate soil quality. Once they have taken hold, the thick spread of invasive plants makes them costly and time-consuming to remove.
General information
Work in moist soil where possible; prioritize removing flowers to prevent seed formation; cut repeatedly at ground level; dig out entire plant and all roots; work on the invasive front first.

Paul Zammit (the section on removal of invasive plants starts at 2:53). He talks about the priority to remove the flowers so the plant doesn't reseed; DON'T PULL IT; continually cut at ground level.
