A review of the relevant national legislation in place (e.g. on nature conservation, water protection, environmental planning) provides an overview on how national legislation supports the implementation of the instrument(s) and identifies the overlaps and gaps with these regulations. The review should not only focus on the existence of national legislation but also encompass its enforcement (e.g. control of hunting, poaching, pollution, and habitat destruction) and the experiences and lessons learned regarding the effectiveness of legal instruments.
