New Scientist has released its latest National Monument Rankings, which measure the national parks that people visit on a daily basis.
The new rankings compare visitor numbers, visitor activity and overall environmental and cultural quality.
In terms of the most popular parks, Yellowstone National Park is the most visited national park with 3.4 million visitors in 2016.
This is up from 2.9 million in 2015.
The next most popular national park is Yosemite National Park, with 1.7 million visitors.
There are three parks with more than 500,000 visitors per day, including the Grand Canyon National Park and Yellowstone National Parks.
There is also an average of 4.3 visitors per hour in each park.
The most popular nature destinations include Great Smoky Mountains National Park (1.8 million visitors per year), Joshua Tree National Park in North Carolina (1 million visitors), and the Grand Tetons National Park of Florida (1,000,000).
In terms a national park’s biodiversity, Yellowstone has the most native plant species and the largest forest area in the United States.
There were 738 species found in Yellowstone in 2016, with an average diversity of 5.1% of all species.
Yellowstone is also home to the tallest mountain in the world, Mount Whitney, and the tallest waterfall in the US.
Yellowstone has one of the lowest average temperatures in the country.
The National Park Service has set a goal to reduce the number of people in the park by 20% by 2030, which would mean the park would be smaller than the combined population of the states of North Carolina and New York.
Yellowstone National park is currently the largest national park in the continental US.
