The park is most well-known for its waterfalls. However it holds many other attractions such as ancient giant sequoia groves, great meadows, amazing valleys and much more. It is also recognized internationally for its clear streams, granites cliffs, biological diversity and 95% of wilderness area.
California has about 7,000 plant species, 50% of which can be found in the Sierra Nevada, and 20% can be found in Yosemite. The unusual rock formations soils in the park make it a suitable habitat for more than 160 rare plants. A bill signed by President Lincoln in June 1864 made the park a protected area.

Old Faithful, a cone geyser, is one of the most popular features in Yellowstone. Lava from volcanic eruptions cover much of Yellowstone’s land area.
Many different types of ecosystems exist in Yellowstone, but the subalpine forest is the largest. The park is a part of the South Central Rockies ecoregion.

Redwood National State Parks are fours parks altogether, located in California’s Humboldt and Del Norte counties. They protect approximately 45% of the remaining coast redwood, which are some of the tallest and most enormous species of trees on earth. These parks also preserve the most indigenous species of flora and fauna, grassland and parts of streams and rivers found along the coastline. For many decades these huge trees were cut down for commercial purposes. Prairie Creek, Del Norte Coast, and Jedidiah Smith Redwoods State Parks and other parks were established in the 1920s in an effort to preserve old growth redwood.
Threatened animals species are also preserved by the ecosystem of the RNSP. These parks were designated a World Heritage Site on September 5, 1980 as well an International Biosphere Reserve on June 30, 2983 by the United Nations.
