'Double-loop learning' in adaptive roe deer management

Adaptive management tackles as well uncertainties regarding the functioning of the managed ecosystem as at the same time the various elements in the decision-making process - this is called the double-learning principle. The multifunctional wildlife management in Flanders is based on the principles of adaptive impact management with a three-year cycle as iterative loop. The basis for this was laid by earlier INBO research (see Huysentruyt & Casaer 2012).

At the Flemish level, however, only the hunting bag and a number of biological parameters of the shot animals are monitored. As a result, it is not possible to evaluate certain management objectives (e.g. natural forest rejuvenation), nor to build up further knowledge about the interactions between humans - animals - vegetation within the management system.

Within this integrated project, data collection will be continued and expanded, using standardised protocols, under the coordination of INBO. Measurements in three areas will take place in a three-year cycle in terms of damage caused by roe deer and measurements of observation probability and annual measurements of management actions (reporting via hunting diaries), the roe deer population trend (mileage indices) and the bio-indicators of the roe deer shot.

The project will be integrated within the three-yearly management cycle for big game management in the various public areas, with annual consultation of all stakeholders.
