The David Sheldrick Wildlife Trust, founded by Daphne Sheldrick after her husband's death in 1977, pioneered the rescue and rehabilitation of orphaned elephants. The orphans, victims of poaching or human-wildlife conflict, are raised in Nairobi, then moved to Tsavo to be reintegrated into wild herds. The Trust perfected milk formulas, socialization protocols, and rewilding techniques, creating a global model for elephant conservation. Daphne died in 2018, but the orphanage continues, a rare conservation success built on patience and deep knowledge of elephant behavior.
