We conducted a research on Vrdovo plateau where we used controlled burning in winter 2021 in order to determine differences between the burnt area and the control area.
In February 2021 our first restoration action of its kind, controlled burning was conducted on an area of 7 ha. Our recent research conducted over a year after the restoration activity shows that regarding the flora, the areas are no different. However, visually the difference is significant. The burnt area is visibly greener as it does not contain any old last-year leaves, which also enable uncontrolled burning as they are the dry material that burns.
It was established that younger shoots of woody vegetation dried out. However, the thicker branches ‘survived’ the burning, therefore small shrubs were successfully removed while the larger bushes and trees do not seem to be negatively affected by the burning.
Based on this, we can conclude that controlled burning during the winter months does not negatively impact the grassland or the more mature vegetation that is present, while at the same time it removes the dry biomass, which if not removed regularly, can facilitate devastating summer wildfires.
