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 brigantina to other "Prunus" species are not yet clear, as an initial molecular phylogeny found that various DNA sequences gave ambiguous indications, and it did not appear to belong in a clade with "Prunus armeniaca". Prunus brigantina Prunus brigantina, called Briançon apricot, marmot plum, and alpine apricot, is a wild tree species native to France and Italy. It is the only apricot-like "Prunus" species native to Europe. The fruit is similar to the commercial apricot "Prunus armeniaca", and is edible. An edible oil produced from the seed, 'huile des marmottes', is used in France. Unlike the other closely related species known
