Segments in this Video

Serengeti National Park (02:37)


Two million wildebeest, zebra, and gazelle participate in the great migration in Tanzania, East Africa. Human activity threatens the ancient route. Scientists are searching for a new way to save animal species around the world.

Serengeti Lion Project (03:54)

Biologist Craig Packer began studying these lions in 1966. Females live communally in prides while males roam and breed with other prides. Isolation of Ngorongoro lions by Maasai villagers leads to inbreeding.

Monitoring Grizzlies (04:58)

Biologists are concerned about the loss of biodiversity on every continent, especially the larger animals. Grizzly bears are now confined to two national parks and areas of Alaska. Biologist Mike Proctor tranquilizes grizzly bears to monitor their health, attaching a radio collar to study how they use their habitat.

Wildlife Genetic Diversity (05:52)

Proctor discovers that genetic pools are becoming isolated due to human developments. Island biogeography studies island-like habitats such as national parks. Michael Soule's studies track how well national parks protect the original species and the balance between males and females.

Protecting Wildlife Habitat (05:17)

When wolves return to Yellowstone, the ecosystem is back in balance. Proctor works to protect key crossing places of wildlife to connect their habitats and enable genetic diversity. An animal corridor opens, beginning at Yellowstone Park and stretching to the Arctic Circle.

Highway Corridors for Wildlife (07:08)

Wildlife conservationists work with landowners and public parks to create corridors for wildlife to cross over or under highways. Landowners are educated on how to protect their livestock and crops with fences and animal-proof bins. Grizzlies are an indicator species; when their needs are protected, so are the needs of 85% of wildlife.

Connecting Animal Corridors (07:08)

Conservationists work with livestock owners to install new fencing that allows wildlife to pass under or over. Nahanni National Park has greatly expanded to become an anchor for the Yellowstone-Yukon corridor, and is a model for similar projects in South America, Africa, Australia, and India. Five nations in Africa are connecting 36 parks to protect elephants and other migrant species.

Migration of Elephants (08:41)

Biologists use airplanes and collars on African elephants to discover where they are hemmed in during their migrations. Farmers shoot elephants because they destroy their crops; wildlife patrols use firecrackers to move elephants. Incentives for wildlife to become a source of revenue for landowners are being developed through eco-tourism industries.

Poaching of Elephants (04:30)

Poaching threatens the migration and survival of elephant families. During the 1990s, elephants were used to feed troops and their ivory used to buy arms, reducing the largest elephant population by half. National parks are important to protect wildlife, but they must be connected to conserve the survival of all wildlife species.

Four-lane highways may be a necessity to our modern society, but they can be a death traps for millions of animals that try to cross them. Around the world, wildlife need to roam for breeding, foraging, and to carry out their traditional migrations–but they are often blocked by ranches, farms, roads, and other human-made obstacles. While national parks and preserves offer some protection to wildlife, even the magnificent Serengeti and Yellowstone parks are too small to sustain healthy populations over generations. But now comes new hope for wildlife through an approach called “connectivity conservation.” Some of the world’s most beloved species–lions, bears, antelope and elephants–can be preserved by linking the world’s wildlife refuges with tunnels, overpasses, and protected land corridors. From North America’s Yellowstone to Yukon Conservation initiative to Southern Africa’s elephant highways stretching across five nations, see how animals are on the move again.
