Though many palm species are strong and plentiful, as many as 100 are threatened by deforestation and unsustainable cultivation practises, such as the heart of palm, which comes from a part of the tree that cannot be regrown. The Hyophorbe amaricaulis palm tree is the most rare. The only one left now resides at the Curepipe Botanic Gardens in Mauritius .
