Résumé

The recent fire history of N Quebec biomes (54 000 km<sup>2</sup>) was documented by examining size and dates of 20th century wildfires using tree ring techniques. Fire frequency per biome decreased S→N from closed forest (0.7 fire/yr) to Shrub Tundra (0.4 fire/yr). Average fire size decreased south-north by 100-fold from ≃8000 ha in the N Boreal Forest to 80 ha in the Shrub Tundra, while modal fire size was <50 ha in each of the 4 biomes. Most fires (>80%) of the N Forest-Tundra and the Shrub Tundra were <100 ha, and fires >100 000 ha occurred only in the N Boreal Forest and the S Forest-Tundra. Less than 35% of all mapped fires in the Boreal Forest were <50 ha, but >30% were >1000 ha. From S→N, the fire-free interval per biome was, respectively, c2.6, 0.6, 0.6, and 2.2 yr, the Boreal Forest data being overestimated. The fire rotation period per biome, based on the percentage of burned areas during 1920-1984 (or 1930-1984 in Tundra), increased S→N by 100-fold from 100 yr in the northern Boreal Forest to 9320 yr in the Shrub Tundra. The fire rotation period around the tree line, ie 20 km south and north of the present tree line, was estimated to be >7800 yr. Biome boundaries have developed and are maintained in response to fire by the ability of spruce Picea spp to seed and regenerate. Stability of northernmost conifer sites is maintained by 1) the inability of patchy shrub and conifer cover in the northern Forest-Tundra and Shrub Tundra to carry fire and 2) failure of trees to produce viable seeds in these 2 biomes. -from Authors
