Switzerland is home to some 10,000 plant species (plants, lichens and mushrooms) and around 40,000 species of animals, 83 species of mammals. Among the latter, most are surprisingly bats or rodents.
The total number of mammals, amphibians, reptiles, birds and wild fish which live and reproduce in Switzerland has remained stable between 1997 and 2007. A small number of species have disappeared, but the deficit was filled by the arrival of new species or recurrence of old species in Switzerland. Some species are parking their own volition in Switzerland (eg wolf), while others have been subject to reintroduction.
In the past, the diversity of species on Swiss territory has fluctuated considerably. It is believed that it reached a maximum in the second half of the 19th century.
Switzerland has signed the UN Convention on Biological Diversity of 1994. This international agreement aims to reverse the decline of species of animals, plants and other organisms. |

While only after conservation efforts were focused on preserving the desert "primitive", it is increasingly evident that few such areas exist.

Nickname this, the current conservation efforts look more and more how adjustments human use in the management of protected areas.

A new paper published in traces of biodiversity conservation of this change in the philosophy of conservation since the 19th century. Reviewing the history of four approaches to conserve strength, a botanist at the University of Cape Town, concluded that current conservation efforts incorporate elements of each philosophy, which results in a new ethic of conservation, which employs alternative criteria for state and control of protected areas, and identify the importance of man's influence in areas of desert.

The species of vascular interest of Saint-Laurent are concentrated mostly in the Lowlands. D'affinity temperate, 114 of these species are confined to the territory. In addition, the occurrence of several species known as thermophiles, whose limit is around the archipelago Hochelaga and Lake Saint-Pierre, is due to contributions made to the southern favour of natural flyways that are Saint-Laurent higher and Richelieu. To this end, parcels with the highest values of the composite index prioritize vascular species are found primarily in the Montreal area (Mount Royal: 0290; Senneville: 0182; island Perrot: 0172; St. Helena Island: 0164 ).
