The World Heritage Committee,
1. Having examined Document WHC-10/34.COM/7B,
2. Recalling Decision 32 COM 7B.4, adopted at its 32nd session (Quebec City, 2008),
3. Welcomes the substantive progress achieved by the two State Parties in strengthening the transboundary management of the property and requests to further strengthen these efforts to ensure a stable management capacity in the two management authorities, establish a fully functional programme of joint meetings of the transboundary management bodies, and ensure adequate resources for the implementation of the Joint Integrated Management Plan;
4. Urges the two States Parties to develop indicators to monitor the state of conservation of the property and better address management and protection concerns, as recommended by the 2006 joint World Heritage Centre / IUCN monitoring mission and encourages using the management effectiveness evaluation methodology which was developed by the World Heritage Centre and IUCN;
5. Requests the two States Parties to ensure that on-going efforts to control invasive species within the property, including the continuation of manual clearance of affected areas and continued investigations of chemical and biological controls are continued and to confirm, through communications to the World Heritage Centre by 31 December 2010, that ongoing funding is in place to ensure this;
6. Reiterates the conclusion of the 2006 mission that any tethered balloon projects close to the property will adversely impact its visual integrity, because when raised the balloon is likely to appear within the viewing corridor of the falls;
7. Also requests the two States Parties to submit to the World Heritage Centre, by 1 February 2012, a jointly prepared report on the state of conservation of the property, including the implementation of the recommendations of the 2006 monitoring mission and status and actions received in relation to the above mentioned factors, for examination by the World Heritage Committee at its 36th session in 2012.
