Tuesday 31st March – Rising temperatures and their influence on ‘algae’ blooms; emphasis on the cyanobacteria (blue-greens) with Shirley French and Queen’s student, Allen Tian. You may have noticed worrisome ‘algae’ blooms in our surrounding waterways over the past several years, they have also been in the news. The concern is; when is it safe to swim in a lake or let our pets drink the water? Is that bloom producing a toxin? That last question can only be answered through more in-depth testing, but, what can we do as citizens? In this workshop we will cover the identification of 5-6 main types of cyanobacteria (blue-greens) that we can look for and some of the algae that indicate healthy waterways. For $18/person you get a Foldscope (pocket microscope & LED magnifier) for quick and easy viewing of bloom organisms. We are hoping for future observations/images to be shared using our phones on iNaturalist or other media. Registration is essential, we have 20 Foldscopes (plus LED magnifiers) to give out (cost of workshop $18/person); up to a maximum of 35 participants (cost of workshop $8/person without a Foldscope). Where: CRCA Outdoor Centre, West Hall, 1641 Perth Rd., Glenburnie. Time: 1:30 to 3:30 pm, March 31, 2020. When you register with shirleyfrencka at gmail.com, let me know if you do NOT intend to take home a Foldscope.
