A scientific legacy

Teaching and research are essential activities at the Gault Nature Reserve. The first scientific studies at the site date back to 1859. Famous scientists such as Sir John W. Dawson, T. Sterry Hunt and Brother Marie-Victorin have explored the vast forests of Mont Saint-Hilaire.

Today there are over 400 scientific articles, nearly 100 graduate and postgraduate theses, more than 50 reports and approximately 30 chapters or books that have focused on Mont Saint-Hilaire.
