Some of our volunteers

Nancy Biggs – Online and Active City Organizer

Nancy studied Biology at Carlenancyton University and has a graduate degree in Environmental Science from Monash University, Australia. Now retired, after 35 years in medical research, Nancy volunteers at Ecology Ottawa, helping with data entry and is involved with the complete streets initiative. She believes climate change is one of the greatest challenges of our time and that Ecology Ottawa, in striving to make Ottawa a more sustainable and livable city, will benefit current and future generations.

Heather Dunlop – Online Organizer

Heather has been a keen environmentalist from the age of 15 when she became involved with a local recycling program. To recycle glass, it first had to be colour sorted and then ground into cardboard boxes and trucked to the recycling depot where boxes of it (and hours of work) were exchanged for a few dollars. Although distracted by other pursuits (biology, nursing, library science), her love of the natural world was never far from the surface. Heather is an avid canoeist, naturalist, and would be gardener. She volunteers at Ecology Ottawa, helping with data entry, and is particularly interested in local initiatives to make it easier for people to adopt a sustainable lifestyle in Ottawa.
