A matriarch's family
Elephant society is built around females. A family of related mothers, daughters and calves follows its oldest female, the matriarch, whose memory of water and routes matters most in a drought. Bulls leave the family as teenagers and spend most of their adult lives alone or in loose bachelor groups.
They eat for most of the day, up to several hundred pounds of grass, bark and branches, and in doing so they shape the savanna, opening woodland and spreading seed.
Amboseli
Amboseli, below Kilimanjaro in Kenya, is home to the longest study of wild elephants anywhere: the Amboseli Elephant Research Project has followed the same families since 1972. Its elephants are among the best known individuals in Africa, and the park holds some of the continent's last big tuskers.
The IUCN moved the savanna elephant to Endangered in 2021 after populations fell by at least 60% over 50 years, mostly to ivory poaching and loss of range. Amboseli's population has grown over the same period, which is why it matters.
