A living museum

Each year, in November and March depending on the species, the Arboretum introduces new species to its site. Over the years, this living tree museum has been enriched with many hardwoods.

Since its creation, more than 400 trees have been planted including 137 exotic species, successfully acclimatised.

A directory of spontaneous or introduced trees, shrubs and shrubs, produced by Dr Henri Sandoz and Dr Guy Aubert is available for download in the scientific committee section.(Lien Rubrique).

Spontaneous essences

Two colonizing species - which have allowed the installation of other woody species - predominate on the Arboretum, Scots Pine and European Larch.

Scots Pine(Pinus sylvestris L.)

Frugal and hardy, it can withstand significant temperature variations, which explains its wide Euro-Siberian distribution and its wide altitudinal distribution.

European Larch (Larix europaea DC. = Larix decidua Miller)

Very resistant to cold, Larch is a continental forest species in full light that likes a dry atmosphere and strong insolation. It is found up to more than 2600 m altitude. The Larch is the only one of our native Conifers to shed its leaves into dazzling needles of yellow hues in Autumn. In spring, it puts on its soft, tender green foliage enhanced by the appearance of young female cones of a superb fuchsia red. Larch has a very long life: it can reach up to a thousand years old!

Les essences introduites

Depuis les premières plantations en 1988, ce sont plus de 130 essences qui ont été introduites sur le site de l’Arboretum. Pins, sapins, mélèzes, cèdres, épicéa et douglas représentent largement la famille des Abiétacées or Pinacées et montre la surprenante diversité du vivant.

Les Erables

Les pays dont ils proviennent sont aussi variés que leurs formes et leurs couleurs. Le visiteur pourra découvrir l’aire aux érables, des arbres provenant de tous les continents. Sont présentes des variétés du Canada, du Caucase, de Chine, du Japon, d’Amérique, et d’Europe.

Le Pin Mugho

Malgré sa modeste taille, et son port très particulier, le Pin mugho (ou pin nain) doit être considéré comme une essence forestière et non comme un simple végétal buissonnant. Son espèce est protégée depuis 1982. Il est le Pin des neiges européen.
