It also concluded that communications between all levels of government and the World Heritage Committee and its Secretariat should be improved so as to avoid that the World Heritage Committee be alerted too late in the process about inappropriate interventions and constructions in or close to World Heritage sites. The Representative of IUCN also commended the importance given in the Hadrian's Wall Management Plan to the site's World Heritage status and drew the Bureau's attention to the excellent emphasis on World Heritage in the planning ordinances for the City of Bath.
