About AFER

CRW_2601Ancient Forest Exploration & Research (AFER) is a non-profit charitable organization formed in 1992. The organization is dedicated to research and education related to ancient and old-growth forests. AFER’s research has focused on identifying and characterizing old-growth forests in Temagami; identifying ancient forest landscapes in central Ontario; and mapping conservation corridors, among other things. The results of this research can be found on the publications page.

AFER was involved in the creation of several educational handbooks and trail guides, including the White Bear Forest guide and the guide to the Blueberry Lake ecology trails. AFER maintains the list of Ontario’s oldest trees, and a database of old-growth forests of North America.
