تاسیس پارک ملی یلواستون در سال 1872 زمینه ساز آغاز جنبش بزرگی در زمینه محافظت از محیط زیست در آمریکا شد. از آن زمان تا کنون، مجموعه پارک های ملی آمریکا گسترش بسیار زیادی یافته است و دربرگیرنده بسیاری از مناطق مانند صخره های مرجانی، قله های مرتفع، نمک زارها و جنگل های بارانی است. اکنون اداره خدمات پارک های ملی ایالات متحده مسئولیت نگهداری از 398 پارک ملی و حیات وحش آنها را بر عهده دارد، تا بازدیدکنندگان بتوانند از میراث طبیعی غنی ما لذت ببرند.

The creation of Yellowstone National Park in 1872 sparked a great American conservation movement and tradition. The American buffalo, or bison, almost decimated in the 19th century, found a home at Yellowstone. Since then, the U.S. national park system has expanded to include everything from coral reefs and alpine peaks to salt flats and rainforests. Today, the U.S. National Park Service looks after 398 national parks — and their wildlife — so that every visitor can enjoy the United States' rich natural heritage.

Badlands National Park, South Dakota

Situated in southwestern South Dakota, Badlands National Park contains 98,743 hectares of eroded buttes and mixed-grass prairie. The park also has one of the world’s richest fossil beds, including the remains of such ancient animals as the saber-toothed tiger. Today, Badlands is home to a different cast of characters: six amphibian, nine reptile, 206 bird, 69 butterfly and 39 mammal species live here. The American bison — the park’s most beloved species — inspired President Theodore Roosevelt’s conservation efforts.

Death Valley National Park, California and Nevada

Straddling the border of California and Nevada, Death Valley National Park boasts smooth sand dunes, etched canyons, colorful badlands and snow-covered peaks. The park contains North America’s driest and lowest spot, which also happens to be the world’s hottest. Despite these extremes — and its name — Death Valley features a variety of wildlife including three amphibian, 36 reptile, five fish, 307 bird and 51 mammal species. The highly adaptable coyote, for example, can be found throughout the park from mountain top to mesquite thicket.
