| Fire plays a major
role in the survival of many vegetation types around the world,
including the jack pine forests of Canada's boreal region and the
prairies of the arid
Great Plains (USA).
The extensive tracts of tallgrass
prairie and oak savanna that
existed in southern Ontario in pre-European times also owed their
survival to fire. Today there are only small remnants of tallgrass
prairie and savanna remaining
in southern and northwestern Ontario, but regular burns are still
required to maintain these endangered plant communities.
