Jersey the island. The species is the subject of an ongoing programme to save it from extinction in Jersey via a collaboration between States of Jersey, Durrell Wildlife Conservation Trust and Jersey Amphibian and Reptile Group (JARG), with support and sponsorship from several other organisations. The programme includes captive breeding and release, public awareness and habitat restoration activities. Trees generally considered native are the alder ("Alnus glutinosa"), silver birch ("Betula pendula"), sweet chestnut ("Castanea sativa"), hazel ("Corylus avellana"), hawthorn ("Crataegus monogyna"), beech ("Fagus sylvatica"), ash ("Fraxinus excelsior"), aspen ("Populus tremula"), wild cherry ("Prunus avium"), blackthorn ("Prunus spinosa"), holm oak ("Quercus ilex"),
Prunus africana buttock", because the two lobes of the fruit resemble the human gluteus maximus muscles. In 1965, Cornelis Kalkman moved "Pygeum" to "Prunus", and this classification has the authority for now. However, a recent cladistic study notes of "Pygeum": "its relationships to "Prunus" remain to be tested by molecular cladistics." "Prunus africana" is known by the common names African cherry, pygeum (from its former scientific name, "Pygeum africanum"), iron wood, red stinkwood, African plum, African prune, and bitter almond. In other languages spoken where it grows, it is known as "tikur inchet" in Amharic, "mkonde-konde" in Chagga, "muiri" in Kikuyu, "entasesa"
