Based on the Terrestrial Ecozones of Canada (Wiken, 1986), this series was developed by State of the Environment Directorate staff of Environment Canada to capture the representative elements of each ecozone using an artistic depiction and providing descriptive text.
Artwork was done under contract by Autumn Downey, Yellowknife, who provided watercolour reproductions.
Most of the text was written by Environment Canada staff—Ed Wiken, John Reid, V. Neimanis, John Anderson, Gary Ironside and many others-- while some was supplied under contract by CYGNUS Environmental Consulting (Jamie Bastedo). Sources of information came from a number of organizations including other government departments, universities, non-governmental groups and consultants.
The text was edited by West Hawk Associates in Ottawa.
Information and reviews were provided by the Canadian Council on Ecological Areas (CCEA).
Design of the poster was completed by Accurate Design and Communication Inc. of Nepean, Ontario.
Northern posters are adapted and reproduced by permission from CYGNUS Environmental Consulting, Yellowknife.
