4. Requests the State Party to continue to address the threats identified in this and previous reports in particular:

a) accelerate the adaptive management changes under the Bison management plan, including:

i) carry out a risk analysis for disease transmission from bison to cattle and include other ungulates by including a review of scientific knowledge on disease transmission, bison behaviour and genetics, and seasonal factors;

b) increase efforts to understand the causes for the slow recovery of the cutthroat trout;

i) carry out a scientific review of the programme to remove the lake trout invasive species;

ii) investigate the effects of reduced lake levels and drought on the cutthroat trout and consider the potential role of climate change in further affecting the recovery of this species;

c) assess the risk to grizzly bears from declining whitebark pine and investigate the severity of bark pine beetle infestation and the role of changing temperatures;

5. Notes the continued pressures from high visitor use and calls on the State Party to:

a) implement a sustainability programme to reduce the impacts of visitation and parks operations to ensure that the Outstanding Universal Value of the property can be transmitted to future generations;

b) continue assessing visitor numbers and the effects of visitor use on the Outstanding Universal Value of the property;

c) continue assessing winter visitation and the effects from snowmobiles;

6. Requests the State Party to invite a joint World Heritage Centre / IUCN Reactive Monitoring mission in 2011 to review progress in implementing the recommendations of the World Heritage Committee;
