Conserving a Legacy: The Surviving Cousins
The cousins of mammoths and mastodons—elephants—are with us today. But for how long? As human
populations expand into once-wild places, elephant populations in Africa and Asia are declining. Scientists are
investigating the extinction of mammoths and mastodons to gain insight into the conservation of elephants
today. Zoologists, park rangers, and everyday people are working around the world to save the last of the great
proboscideans.
The savanna elephant is one of two
surviving species of elephant in Africa
today. The other is the forest elephant.
Savanna elephants travel in matriarchal
herds—family groups led by older females.
Male elephants leave the herd as teenagers
and live mainly solitary lives. In the late
1800s, an estimated five million savanna
elephants roamed Africa. Today there are
less than half a million, due largely to
poaching and diminishing habitat caused
by climate change and competition with
humans. Savanna elephants are at home
in the grasslands of Africa, and wild
populations currently survive in southern
Africa, eastern Africa, and parts of western
Africa. African forest elephants, however,
are at home in the tropical and subtropical forests of Africa. Currently, wild populations of forest elephants live
in West and Central Africa.
The Asian elephant is the most endangered species of elephant in the world today. Current estimates suggest
that only about 30,000 Asian elephants survive worldwide. They are at home in tropical and subtropical
forests of southeast Asia, and current wild populations survive in India, Nepal, Bhutan, Bangladesh, Sri Lanka,
Myanmar, Thailand, Loas, Cambodia, Vietnam, China, Malaysia and Indonesia.
