The Arboretum de Tournay (9 hectares) is an arboretum located in Tournay, Hautes-Pyrénées, Midi-Pyrénées, France. It is managed by the Office National des Forêts and open daily without charge.
An arboretum in a general sense is a botanical collection composed exclusively of trees. More commonly a modern arboretum is a botanical garden containing living collections of woody plants and is intended at least in part for scientific study.
Tournay is a commune in the Hautes-Pyrénées department in south-western France.
Hautes-Pyrénées is a department in southwestern France. It is part of the Occitanie region.
The arboretum was established in 1992, following a proposal by M. Patrick Pierquet, on woodlands that had been reforested in 1958 after a fire. The arboretum contained 70 species at inception, which collection has now grown to 170 species including Acer griseum , Cornus florida rubra, Fagus sylvatica , Ginkgo biloba , Magnolia macrophylla , Pyrus salicifolia , Torreya nucifera , and Ulmus parvifolia
In biology, a species ( ) is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. While these definitions may seem adequate, when looked at more closely they represent problematic species concepts. For example, the boundaries between closely related species become unclear with hybridisation, in a species complex of hundreds of similar microspecies, and in a ring species. Also, among organisms that reproduce only asexually, the concept of a reproductive species breaks down, and each clone is potentially a microspecies.
Acer griseum is a species of flowering plant in the family Sapindaceae, native to central China. Acer griseum is found in the Chinese provinces of Gansu, Henan, Hubei, Hunan, Shaanxi, Shanxi and Sichuan, at altitudes of 1,500–2,000 m (4,921–6,562 ft).
Cornus florida, the flowering dogwood, is a species of flowering plant in the family Cornaceae native to eastern North America and northern Mexico. An endemic population once spanned from southernmost coastal Maine south to northern Florida and west to the Mississippi River. The tree is commonly planted as an ornamental in residential and public areas because of its showy bracts and interesting bark structure.
