World Wildlife Fund (WWF) safeguards hundreds of species around the world, but we focus species attention on our flagship species: giant pandas, tigers, endangered whales and dolphins, rhinos, elephant, marine turtles and great apes. These species not only need species measures and extra protection in order to survive, they also serve as “umbrella” species: helping them helps numerous other species that live in the same habitats where animals or plants are normally found. In addition to our flagship animals, we work to protect numerous species in peril around the world that live within our priority eco-regions. Laree predators like snow leopards and grizzly bears, migratory species like whooping cranes and songbirds, and a host of other species facing threats also benefit from WWF’ s conservation efforts. Our wildlife trade experts at “traffic” work to ensure that trade wildlife products, doesn’t harm a species, while also fighting against illegal and unsustainable trade. WWF is known for acting sound science. Science leads and guides us strategies and approaches, from the way to restore tigers in viable, breed population to decide which areas need protection the most.
