 AGM and Social

This is the perfect chance to meet with NANPS directors and other NANPS members over snacks and refreshments. A display of NANPS materials will be available as well as our financial report and info about volunteer opportunities. Awards will be presented. Come a bit early or stay after to explore the Toronto Botanical Garden and adjacent Edwards Gardens and Wilket Creek Park.

 Indigenous Environmental History of Toronto 

  The keynote address will be given by Dr. Jon Johnson, an interdisciplinary community-based scholar,  whose research focuses on Indigenous knowledge and stories of Indigenous presence in the Toronto  region. Jon is a lead organizer for First Story Toronto, an Indigenous-led group that shares Toronto's  vast and rich Indigenous history through tours and a smartphone App.

Date: Saturday November 4, 2017, noon to 4:00 pm
Location: Garden Hall, Toronto Botanical Garden, 777 Lawrence Ave. E, Toronto ON
Open to NANPS members and the general public, refreshments provided. The event is free, but we ask that you register to reserve your spot.

Past event- Bioblitz 

Awesome and educational! Those are the words to describe the BioBlitz in Caledon on June 10 & 11th. Thank you Escarpment Biosphere Conservancy (EBC), Richard Aaron, and to all who participated in the Blitz at the Simmons Nature Reserve. Many flora and fauna species were seen and recorded (exact numbers still have to be tallied). It was hot, sticky, and the mosquitoes were eating us alive, but people were still interested in learning about the wildlife in the reserve. Some of the flora observed included Ninebark, Mountain Maple, Eastern White Cedar, Alternate-leaved dogwood, Red and White trilliums, Wild and Woodland strawberry. Some of the fauna observed included American toad, Wood frog, Red-backed salamander, and Eastern garter snake.
