Arctos - Conservation of the brown bear: coordinated actions for the Alpine and Apennine area
Redevelop, recover, and re-spread the buckthorn (Rhamnus alpina), through experimental silvicultural interventions of thinning in beech forest, coppicing of old buckthorn plants and planting of new seedlings, thus guaranteeing the long-term productivity available for bears.
Good Practice Description
The interventions that can favour the restoration, depending on the situation, are:
• the thinning of the forest stands (typically beech woods) in contact with the buckthorn areas;
• the coppicing of old buckthorn plants;
• protection of the buckthorn from overgrazing;
• the planting of new seedlings.
To evaluate the opportunity of intervention in nearby forest stands which are encroaching the areas with buckthorn the interface index is used, intervening in the case of a value greater than or equal to 50%. The intervention will have to provide for the progressive thinning of the margins to increase the amount of solar radiation on the buckthorn plants. If possible, aim for elliptical holes with an east-west orientation.
To revitalize the buckthorn plants that are a little dry or damaged by grazing, the stumps can be cut at the base in order to stimulate their regrowth. Provide protection to groups of stumps with chestnut poles and wire mesh positioned so as to hinder wild and domestic animals, but not the bear.
The good practice was applied to buckthorn plants found in wooded pastures surrounded by forest stands of the Abruzzo, Lazio, and Molise National Park.
Coppicing and thinning of adjacent stands do not present particular technical difficulties and can, therefore, be replicated in other contexts characterised by the presence of bears and buckthorns that need to be restored and spread. In the case of areas with a strong presence of wild and domestic animals grazing, provide suitable and effective protection systems.
