The arboretum was created 1900-1910 for experimental introduction of foreign species into France.
Scientific efforts ceased in 1963, and it has subsequently been maintained for educational purposes by the Office national des forêts.
The site is on a southwest slope between 900 and 1500 metres altitude in an environment very conducive to forest vegetation; some trees reach heights that are records for Europe.
Its hardwoods include ash, beech, birch, cherry, chestnut, red oak, and sycamore.
