Hawai’i Volcanoes National Park, Hawaii
Located on Hawaii’s Big Island, this unique park encompasses two active volcanoes and offers a glimpse into rare and endangered Hawaiian species found nowhere else on Earth. The park protects the endangered Hawaiian hawk (‘io), which holds cultural significance for native Hawaiians and plays an important role in the island’s ecosystem as a top predator. Visitors may also encounter the Hawaiian goose (nēnē), Hawaii’s state bird that has been brought back from the brink of extinction through intensive conservation efforts. With fewer than 2,500 individuals remaining in the wild, spotting a nēnē is a special experience. The park’s diverse ecosystems, from coastal areas to high-elevation forests, also harbor endangered Hawaiian plants such as the Mauna Loa silversword, which blooms once after decades of growth before dying. Conservation programs within the park continue to combat threats from invasive species and habitat loss to protect these irreplaceable Hawaiian treasures.
Channel Islands National Park, California
Often called “North America’s Galapagos,” the Channel Islands harbor numerous endemic species that evolved in isolation from the mainland. The park provides critical habitat for the endangered island fox, which occurs on six of the eight Channel Islands and nowhere else in the world. After populations plummeted to fewer than 100 individuals on some islands in the 1990s, intensive recovery efforts have brought these diminutive foxes back from the brink. The waters surrounding the islands are part of a marine sanctuary where visitors can observe endangered blue whales—the largest animals on Earth—feeding during summer months. The coastal waters also support threatened Guadalupe fur seals and endangered southern sea otters. Birdwatchers might spot the island scrub-jay, found only on Santa Cruz Island, while plant enthusiasts can search for rare endemic wildflowers that bloom after winter rains. The park’s isolation has protected many species from development, though introduced species and climate change continue to pose significant challenges.
Olympic National Park, Washington
This diverse park encompasses nearly a million acres of protected wilderness, including glacier-capped mountains, old-growth temperate rainforests, and over 70 miles of wild coastline. The park’s varied ecosystems provide habitat for several endangered species, including the northern spotted owl, whose declining population triggered significant changes in logging practices throughout the Pacific Northwest. The park’s pristine rivers support threatened bull trout and one of the healthiest populations of endangered chinook salmon on the West Coast. Along the Olympic coast, visitors might glimpse the marbled murrelet, an endangered seabird that nests high in old-growth trees, highlighting the interconnectedness of the park’s marine and forest ecosystems. The park also protects the Roosevelt elk, named for President Theodore Roosevelt, who established the Olympic Game Reserve in 1909 to protect these magnificent animals from overhunting. Conservation efforts within the park focus on habitat restoration and combating climate change impacts, which threaten the park’s iconic glaciers and the species that depend on them.
Okefenokee National Wildlife Refuge, Georgia
This vast wetland complex in southeastern Georgia protects one of the largest intact freshwater ecosystems in North America. The Okefenokee serves as a stronghold for the threatened eastern indigo snake, North America’s longest native snake species. These non-venomous predators can grow to over 8 feet long and play an important role in controlling rodent populations. The refuge also harbors red-cockaded woodpeckers, endangered birds that excavate nesting cavities in living pine trees affected by heartwood fungus. Bird enthusiasts should scan the skies for wood storks, large wading birds whose distinctive feeding technique involves sweeping their partially open bills through shallow water to detect prey. The Okefenokee’s extensive cypress forests and blackwater swamps provide ideal habitat for the American alligator, which, while no longer endangered, represents a remarkable conservation success story. The refuge offers canoe and kayak trails that allow visitors to explore this primeval landscape while possibly encountering these remarkable species in their natural setting.
Arches National Park, Utah
Known for its stunning red rock formations and natural stone arches, this desert park in eastern Utah also provides habitat for several threatened desert species. The park’s rugged canyons and remote backcountry offer refuge for the Mexican spotted owl, a threatened subspecies that nests in caves and crevices within the sandstone cliffs. Desert bighorn sheep, once eliminated from the area but successfully reintroduced, can sometimes be spotted traversing the park’s steep terrain. Though elusive, these agile animals are adapted to the harsh desert environment with specialized hooves that allow them to navigate precipitous cliff faces with remarkable ease. The park also protects several rare plant species, including the Entrada rushpink, which grows nowhere else in the world. This delicate desert wildflower has adapted to survive in the harsh conditions of the Colorado Plateau. The park’s conservation efforts focus on minimizing human impacts on sensitive desert ecosystems, which can take decades or even centuries to recover from disturbance due to the arid climate and fragile soils.
Great Smoky Mountains National Park, Tennessee/North Carolina
As America’s most visited national park, the Great Smoky Mountains harbor an extraordinary diversity of life forms, including several endangered species. The park serves as a critical sanctuary for the endangered Carolina northern flying squirrel, which glides through the high-elevation forests using a special membrane that stretches between its limbs. Salamander enthusiasts might search for the Junaluska salamander, an endangered amphibian found only in this region of the Appalachian Mountains. The park harbors more salamander species than anywhere else in the world, earning it the nickname “Salamander Capital of the World.” The park’s rivers support several endangered fish species, including the smoky madtom, a small catfish thought extinct until rediscovered in the 1980s. Plant lovers can admire the spreading avens, an endangered flower that grows only on a few high mountain peaks in North Carolina and Tennessee. Conservation challenges in the park include air pollution, which threatens the health of forest ecosystems, and the introduction of non-native pests like the hemlock woolly adelgid, which has devastated the park’s eastern hemlock forests.
Glacier National Park, Montana
Known as the “Crown of the Continent,” Glacier National Park protects some of America’s most intact wildlands and provides crucial habitat for threatened grizzly bears. The park and surrounding areas comprise one of the few places in the lower 48 states where these magnificent predators still roam. Patient wildlife watchers might also spot the threatened Canada lynx, a medium-sized wild cat with distinctive ear tufts and large, fur-covered paws that act like natural snowshoes. The park’s pristine lakes and streams support bull trout, a threatened species that requires cold, clean water to survive. Along alpine ridges, keen observers might glimpse the rare wolverine, one of North America’s most elusive mammals, capable of traveling 15 miles per day through deep snow in search of food. The park faces significant conservation challenges, most notably climate change, which has already caused substantial glacial retreat. Scientists predict the park’s namesake glaciers could disappear entirely by 2030, with profound implications for the park’s ecosystems and the species that depend on them.
Big Bend National Park, Texas
Encompassing the largest protected portion of the Chihuahuan Desert in the United States, Big Bend National Park offers refuge for numerous species adapted to this harsh but beautiful environment. The park protects habitat for the black-capped vireo, a small endangered songbird that nests in dense shrublands. Though once on the verge of extinction, conservation efforts have helped populations begin to recover. Along the Rio Grande, which forms the park’s southern boundary, visitors might spot the Rio Grande silvery minnow, an endangered fish that has disappeared from more than 95% of its historical range due to dam construction and water diversion. The park also harbors several endangered plant species, including the Chisos Mountains hedgehog cactus, which produces spectacular magenta flowers in spring. Bat enthusiasts should visit the park’s Mariscal Mine at dusk to witness thousands of Mexican long-nosed bats emerging to feed on the nectar of agave plants. These endangered pollinators play a crucial role in the reproduction of agaves, which are essential for tequila production. The park’s remote location has helped preserve its biodiversity, though drought and climate change present ongoing challenges.
Dry Tortugas National Park, Florida
Located 70 miles west of Key West in the Gulf of Mexico, this remote park consists of seven small islands and the surrounding waters. The park provides critical nesting habitat for the threatened loggerhead sea turtle, which comes ashore on the park’s beaches to lay eggs between April and September. Visitors may also spot the endangered green sea turtle, which feeds on the park’s extensive seagrass beds. The Dry Tortugas are also internationally recognized as important bird territory, with Bush Key serving as one of the most significant nesting sites for the sooty tern in the Western Hemisphere. The park’s pristine coral reefs support a remarkable diversity of marine life, including the threatened Nassau grouper, once abundant throughout the Caribbean but now rare due to overfishing. The park’s isolation has helped preserve its ecosystems, though rising sea temperatures threaten its coral reefs through bleaching events, and sea level rise may eventually submerge the low-lying islands that provide crucial nesting habitat for sea turtles and seabirds.
Yellowstone National Park, Wyoming/Montana/Idaho
America’s first national park remains one of its most important sanctuaries for endangered wildlife. The park’s remote backcountry provides habitat for the threatened Canada lynx and the endangered North American wolverine. The park also protects critical habitat for the grizzly bear, which has made a remarkable recovery in the Greater Yellowstone Ecosystem since being listed as threatened in 1975. Perhaps the park’s most famous conservation success story involves the gray wolf, reintroduced in 1995 after being completely eliminated from the park in the early 20th century. Visitors today have a chance to observe these apex predators in the Lamar Valley, often called “America’s Serengeti.” The park also harbors one of the largest public herds of American bison, which narrowly escaped extinction in the late 1800s when fewer than 25 wild bison remained in a remote corner of the park. Though no longer endangered, the Yellowstone bison represent a conservation triumph and the only continuously wild herd in the United States. The park faces ongoing conservation challenges, including climate change, non-native species invasion, and balancing visitor access with wildlife protection.
Redwood National and State Parks, California
Home to the tallest trees on Earth, this park complex protects 45% of remaining old-growth redwood forests and provides critical habitat for several endangered species. The parks harbor the marbled murrelet, an endangered seabird that flies up to 50 miles inland to nest in the canopy of ancient redwoods. Visitors exploring streams within the parks might glimpse the endangered coho salmon, which returns from the ocean to spawn in the same freshwater streams where it was born. The northern spotted owl, another endangered species, finds ideal habitat in the parks’ old-growth forests, where it hunts small mammals beneath the redwood canopy. Along the coastline, tidepools harbor the endangered black abalone, a marine mollusk that has suffered devastating population declines due to overharvesting and disease. Conservation efforts within the parks focus on restoring previously logged areas to recreate old-growth forest conditions, removing roads that cause erosion affecting salmon streams, and managing invasive species that threaten native plants and animals. The parks represent a remarkable conservation achievement, preserving ancient forests that might otherwise have been lost to logging.
