Weed of the month
From the Land Management Coordinator:
I’m going to try to introduce a new weed to Crystal Waters each month (on this website, not onto the land!). They’ll be ones that already occur here and I’ll try to give some information about their severity at Crystal Waters, what impacts they have on our environment and what can be done to control them. Rhea Phelan, Weeds Officer at Sunshine Coast Council, is helping to provide some of the information. Photos will assist with identification. For further help with identification or control methods, please contact me: amy.cwbc@gmail.com.
