The toromiro tree persists today only in cultivation. In 1955 - 56 a Norwegian archaeologist and explorer, Thor Heyerdahl, collected seeds from the last remaining Sophora toromiro tree, protected within the volcanic crater on Easter Island (4). It is thought that trees found today in European botanic gardens are all descended from this one specimen (4). Other toromiro trees are known from botanic gardens in Chile and Melbourne and from private collections. The Toromiro Management Group (TMG) is responsible for managing these collections to ensure that this tree is not lost forever. The TMG is a consortium of botanic gardens, geneticists, foresters and archaeologists working together to secure the future of the tree, and ultimately to re-introduce it to Easter Island (5).
