Abstract

A vegetation survey was initiated to monitor the pattern of natural revegetation resulting from a 1976 forest fire in the Ignace area of Ontario. During the period 1976 to 1980, a total of 316 site inventories on burnt and non-burnt sites was conducted recording 88 different species in 32 sampling days. Ground cover vegetation on burnt-over areas reached the same density as that of non-burn areas in the third growing season following the fire. By the fifth year following the fire, shrub cover was re-established at an approximate height of 2 m. and with a cover factor of 75% pre-burn conditions. No significant change in canopy cover on burnt-over areas was noted during the 5 year study. The greatest changes in species numbers occurred during the first 2 growing seasons. Two types of vegetational species changes were noted, annual succession and re-colonization. Each was identified during the first 3 growing seasons.
