The best time of year to visit scenic natural landscapes in the U.S. is late March through mid-May, according to the Natural Geology Association (NGA).
The organization says March is when most of the country is covered by trees and vegetation.
The average number of trees per acre is 1.9 in Kansas, 1.4 in Oklahoma and 1.1 in Mississippi, according the NGA.
The highest number of tree-covered acres is in South Dakota, at 2.6 in the state’s southwest corner.
The next highest is in Arkansas, at 1.6.
Natural scenery is the main reason many people visit the state in the spring and summer, said Bob Gelles, president of the NGAs association.
Natural scenery provides a variety of plant life that help to maintain and replenish habitat, which can be crucial for wildlife and other wildlife species, Gellas said.
Gelles said the best places to visit for natural scenery in the fall and winter are in the southern U.A. and southwest parts of the state, with the exception of Oklahoma, which has more snow.
But the U-shaped terrain of the plains also provides some of the most spectacular natural scenery.
The NGAs list of most visited natural scenery states includes Kansas, Missouri, Tennessee, Georgia, Arkansas, Alabama, Texas, Florida, Nevada and the Carolinas.
Natural terrain in those states is sparse and sparsely populated.
Natural landscapes in Oklahoma are sparse and densely populated, according a report from the state last year.
Natural landscapes in Mississippi have fewer trees and have less vegetation.
The southern portion of the Mississippi River is dominated by oak savannah and prairie.
But those savannahs are being replaced by grasslands and wetlands.
Natural landscape areas in Alabama include the mountains and wetlands of the Gulf Coast and in Florida, where the state has large portions of the bay.
Natural landscape areas also include parts of South Dakota.
Natural terrain areas in Mississippi and Alabama are mostly forested, and some have scattered croplands, said Scott Kress, director of the Natural History Museum of Mississippi.
But they have not experienced a lot of erosion, he said.
The state has seen a lot more development of wetlands, Kress said.
Natural scenic scenery areas in Tennessee include the state of Georgia, which is mostly mountainous, and parts of Tennessee and Alabama.
Natural vegetation areas in Oklahoma include the coastal plains, coastal marshes and the Great Plains, according Kress.
They include the plains of northern Oklahoma and parts in southern Arkansas.
Natural beautyNatural scenery areas and natural scenery areas are not interchangeable.
Natural scenic scenery is more important for wildlife than natural beauty, said Gellis.
Natural beauty includes all of the plant life in the environment, including trees, shrubs, grasses and ferns, Glles said.
But natural beauty is less important for natural landscape.
