Officials in China are planning to establish a national park that will potentially be 60% larger than Yellowstone. The conservation efforts of the park focus on two endangered big cats. The Amur leopard and the Siberian tiger are two of the rarest big cats on the planet, with their numbers at one point reaching lows of 30 and 40 respectively. Although China has had many areas designated to protecting wildlife, they were plagued with mismanagement and general inefficiency. They are bringing in help from the Paulson Institute in Chicago to help create a national park that will be effective and comparable to other national parks on the international level. China will begin with a series of smaller pilot parks over a three year period. This will provide immediate conservation effects and allow the government to work out any issues with the current park system.
