Abstract

Fire is increasingly posing a risk to forests and plantations, even in the temperate latitudes of central Europe. Little is known about fire ecology in this region, and therefore, appropriate approaches for the management and reforestation of burned sites are mostly lacking. In a Scots pine plantation region in Brandenburg (northeast Germany), the early tree regeneration of two nearby areas that burned 1 year apart was investigated. We observed that 3 years after the fire events, the forest in one study area showed a relatively high regeneration with a mean density of 7765 saplings/ha, clearly dominated by European aspen (93%); whereas the other study area showed a lower mean density of 5061 saplings/ha, dominated by Scots pine (71%) and aspen (15%). Three years after the fires, the difference in aspen density was 11-fold between the two areas. We studied the effects of several variables about soil and environmental properties on the aspen establishment in these two study areas in the second and third years after the fire events. We found that the post-fire aspen regeneration was influenced by several factors, including soil texture, soil disturbance from forest management, volume of deadwood, and browsing. We also discussed that weather conditions during seed production and germination might have played a role in the difference in aspen establishment between the two study areas. We concluded that the post-fire forest regeneration potential in the study region is highly variable and could come under critical pressure as climate change progresses.
