The Stanley Park Ecology Society is monitoring the Heron Nesting sites in Stanley Park for several organizations and studies. The provincial government's Ministry of Water Land and Air Protection is conducting research to determine the impact of predators and human interaction on nesting Great Blue Herons. The data will also be forwarded to Bird Studies Canada to contribute to their national study of nesting habits and trends.
SPES volunteers observe the herons and their activity from different vantage points around the heronry and have done so for a number of years.
