When the glacier that completely covered Ontario about 18,000 years ago melted and retreated northward, plants, animals, fungi, and micro-organisms began to re-colonize the province, mainly from refugia (areas that were not glaciated) to the south and east of Ontario.
There are many similar stories of island refugia becoming almost the sole home for particular fauna: black robin on Chatham Islands; North Island saddleback on Hen Islands; stitchbird and kokako birds on Little Barrier Island; kakapo birds on Codfish Island; giant weta insects on Poor Knights Islands; tuatara lizards on Stephens Island; and little spotted kiwibirds on Kapiti Island.
Areas known as refugia have helped preserve biodiversity during previous periods of major climate change, and could once again in the future, according to Associate Professor Stephen Williams, director of the Centre for Tropical Biodiversity and Climate Change at James Cook University in Townsville.
