A study of 59 sites in the Central Yukon showed no strong correlation between plant community and time since burning, the post-fire seral communities being both site and fire-specific. Fire intervals were 33, 69, 57 and 62 years in the South Ogilvie, North Ogilvie, Eagle Plains and Berry Creek eco-regions respectively. More than three-quarters of the stands sampled were overmature and therefore vulnerable to burning. Burning is a recurrent natural habitat factor. ©1982 Elsevier Science.
