Huge territories of the North American continent amaze the diversity of the plant world. Each landscape zone has a certain number of rare, unique and relic plants growing on its land.
Subtropical deserts and semi-deserts in the south are quickly overgrown with thorny shrubs, various cacti, aggressively prolific prickly pear prickly pears, slender idrias reaching 10-meter height, grow interspersed with stunted, but incredibly tenacious coryphanthus trees. All these plants are the true nature of America, examples of many years of evolution.
To the north, deserts of a more moderate climate begin, cacti gradually give way to bushes of wormwood, quinoa and teresken. The wildlife of America is unique in its splendor. The territory of the United States, from the Appalachian mountains in the east to the rocky Cordilleras in the west, is a series of flowering valleys and barren plateaus, the richest pastures on the prairies and endless rocky plains. The whole nature of America is built on contrasts. Therefore, the most fertile and picturesque areas are reserved for national parks. The main US reserve, Yellowstone Park, spreads over a vast area of almost a million hectares.
The park was created one hundred and fifty years ago, despite its name - “yellow stone”, is one of the greenest places on the planet. Yellowstone Park is famous for its hot springs, geysers and an active but still quiet volcano.
To the east, in Florida, is another national park, the Everglades. Rare plants, trees and flowers live in this park, in total about 2000 items. The park is the only place where all kinds of wild orchids grow. For a long time they tried to ennoble the territory of the Everglades Park, drained the marshy soils in every possible way, but in the end, by the decision of UNESCO, it was declared a wildlife zone and it was left alone.
There was no need to drain another US National Park - Death Valley, because it is located in the driest place in North America, east of the Sierra Nevada massif, in California, where America's nature is concentrated in its best forms. The park got its dark name during the gold rush on its territory, when the search for a gold mine was marked by several deaths.
Giant sequoias grow in Death Valley
; there are no such trees anywhere else in the world. The height of the giants is about one hundred meters, and the trunk diameter reaches ten meters. Each tree is considered the property of American society and is inviolable.
The fauna in
North America is no less diverse than the plant world. The diversity of the animal world is due to several climatic zones.
Reindeers, polar bears, wild musk oxen,
polar wolves, arctic foxes are found in the cold tundra forests. The climate in the taiga zone is softer, which means that the nature of America is already different, different from the northern zone. American bison live in the taiga and in many fur-bearing animals, marten, sable, mink and weasel. Large animals are represented by brown bears and wolverines.
In the
Mississippi River Valley, you can find unique alligators and no less unique Mississippi turtles. Flamingos, ibises and pelicans live in huge flocks near the water. In the green splendor of the Great River basin, millions of miniature hummingbirds found shelter and food. The Missouri River, a tributary of the Mississippi, is also rich in fauna.
The nature of the United States does not tolerate emptiness. Some species of animals and birds of North America disappear, but in general the ecological situation favors the continuation of the life of carnivorous and herbivorous animals, birds, reptiles, and insects. In place of endangered species, new populations appear.
