Table 1 Mean regeneration density (± standard error) expressed as average stems per hectare pre-fire or in unburned areas and in burned areas. “Difference” was calculated by subtracting pre-fire/unburned average recruitment from burned average recruitment and then dividing by pre-fire/unburned recruitment and multiplying by −100

From: Post-fire forest recovery at high latitudes: tree regeneration dominated by fire-adapted, early-seral species increases with latitude
