Abstract: Coinciding with the 40th anniversary of Earth Day, this research describes short and long term memories of participants who attended past and present Earth Day Celebrations in Surrey, BC, Canada. Particular interest was placed on discovering the most memorable aspects of their Earth Day experiences as well as determining motivations to attend. Research was conducted using online and face-to-face surveys administered prior to and during the April 2010 event. The study revealed that not only that hands-on stewardship activities of releasing salmon and planting trees proved the most popular among research subjects but also illuminated the importance of social and familial interactions at the event. The results of the study may serve to guide the efforts of event organizers in order to capitalize on the publics interests in environmental special events and serve to meet both the environmental and social needs of the community.
