Climate change threatens to undermine the conservation values of protected areas, such as Khuvsgul Lake National Park (KLNP), one of Mongolia’s largest and most visited parks. Khuvsgul Lake is sacred to Mongolians and is known locally as the Blue Pearl. This publication presents the first quantitative assessment of the potential impacts of climate change to a protected area in Mongolia in relation to three dimensions: biodiversity, livelihoods, and tourism. Building resilience to climate change for the KLNP is critical and requires collaboration and coordination between national and international agencies, focused on addressing unsustainable livestock grazing and unmanaged tourism, improving habitat connectivity, and strengthening park management.
