Decisions adopted by the Committee in 1991
15 BUR VI.28
Iguazu National Park (Argentina) / Iguaçu National Park (Brazil)

The Bureau recalled that these two sites cover the same waterfall area which extends across the two countries. The Bureau was concerned that, for tourist purposes, eight helicopters now simultaneously overfly the falls causing serious acoustic disturbance in an otherwise natural setting, and that more than 7,000 visitors have registered complaints. The Bureau also noted that local non-governmental organizations are opposing the use of helicopters as an inappropriate activity that contravenes legal air traffic regulations for flights over protected areas. The Bureau requested the Secretariat to convey these concerns to the authorities of Argentina and Brazil and suggest that they co­operate in devising management strategies to control helicopter tourism of the area.

The Committee noted that eight helicopters simultaneously overfly these adjacent sites which cover the same waterfall area. Over 7,000 visitors had registered complaints and local conservation groups are opposed to the use of helicopters in the area because it contravenes legal regulations for air traffic over protected areas. The Brazilian Delegate informed the Committee that a working group had been established to study the matter with a view to introducing more stringent regulatory measures for helicopter tourism. The Committee requested the Secretariat to contact the authorities of Argentina in order to request information on steps taken by them.
