The Research Group on Introduced Species (RGIS) developed from collaborative work between partners from Canada and France. It took shape in the nineties to conduct research and publicize information on the effects of introduced species on natural ecosystems within the Haida Gwaii archipelago (aka Queen Charlotte Islands) in British Columbia, Canada, and to draw more general lessons on the ecology of temperate forests.

In 2001, it was registered as a not for profit trust based in Queen Charlotte City. It is an international consortium that brings together:

It maintains close collaborations with several universities and research agencies from Canada and France.

The main thrust of RGIS projects has been to explore the impacts of introduced black-tailed deer and, to a lesser extent, red squirrels on forest ecology in the archipelago.

The emphasis has been on natural forest ecosystems, but work on commercially managed forests has also been included.

A major field program, aimed at elucidating the costs of the introduced deer to the overall biodiversity of the archipelago, peaked during 1996–2002, involving 14 scientists and 9 graduate students. This research is ongoing
through the monitoring of long term changes in the absence or presence of deer population regulation.

In 2011 we launched a second major field program, to study the role of predation risk on the interactions between deer and the forest (ANR-BAMBI). It involves 5  academic partners from France (CEFE-CNRS, CEFS-INRA, Université Paul Sabatier) and Canada (University of Northern BC and Université Laval à Québec) and in 2012 keeps 3 phD student and several master students busy. It is also supported by the Laskeek Bay Conservation Society and Gwaii Haanas National Park Reserve, Heritage Site and Marine Conservation Area.
