Bringing back Paradise at the Ajax lakeshore

Join us for Paradise Beach Project planting event September 20, 2014

Sierra Club, Town of Ajax and Toronto and Region Conservation are psyched to plant native plants and trees on Paradise Beach bioswales as part of the Great Canadian Coastal Clean-up Saturday, September 20th. 

'What's a bioswale?' you may ask. A bioswale is a way of filtering surface water by channeling through plants, gravel or rip-rap and slowing it down. Silt and particulate matter will fall out and the plants in the bioswale help take out nutrients and chemicals, for instance automotive run-off from a parking lot. The plants and soil do this work for free for our benefit!... Read more »

Low calving rates among blue whales cause for concern

Each blue whale has a unique pattern of spots of its back, like a fingerprint or a nametag. These spots allow researchers to identify each whale as either a newcomer, or an old friend.

The Mingan Island Cetacean Study (MICS) is a non-profit research organization located on the Gulf of St Lawrence's northern shore and they were the first group to begin long term study of marine mammals in the Gulf. Since their founding in 1979, this group has followed blue whale populations in eastern Canada, the Sea of Cortez and in the waters of Iceland.

MICS has discovered something troubling in the northwest Atlantic blue whale population. Of the 475 individual whales they've identified since their genesis in 1979, only 22 have been calves. This suggests a frighteningly low calving rate for a population already swimming on the brink.... Read more »

Blue whale receives honourable mention as Atlantic chiefs call for moratorium

"The Atlantic Salmon and the blue whales are both very precious creatures to our nations," said Chief Claude Jeannotte of Gespeg, Quebec. He spoke in Halifax on behalf of these two struggling species Wednesday, July 16.

Jeannotte was accompanied by four other First Nations chiefs from across Atlantic Canada, all from communities dependent on the, "rich bounty of the Gulf," in the words of Chief P.J Prosper, representing the Migmaq of Nova Scotia. Together they spoke against exploratory drilling at the Old Harry Prospect, located in the Gulf of St Lawrence 80 km off Newfoundland's west coast and 460 metres underwater.

The Old Harry prospect is expected to be drilled in 2015 or 2016, according to the oil and gas company Corridor Resources which presently holds an exploratory license in the region.... Read more »

Brampton's Natural Capital

Natural Capital refers to the stock of natural resources and environmental assets, and how they contribute to building healthy communities. The Natural Capital perspective is a way of placing a monetary value on the ecological goods and services to quantify these benefits.  

Brampton's ecosystems contain many natural areas and urban green spaces that provide the city with ecological goods and services, which translates to valuable Natural Capital.  

Thanks to support from Ontario Trillium Foundation and the Mississauga Community Fund, we are expanding the project by doing walkshops and natural area restoration work throughout Brampton and Mississauga in summer of 2014.  Our goal is to educate and engage the community to raise awareness and appreciation for these natural areas.  ...
