Regression of floristic diversity (trivialization of flora) :
- Regression of wetlands- Changes in agricultural practices (agricultural intensification)
- Increased urbanization

The « Atlas de la flore d’Auvergne », a tool to know the effects of climate change :
- Comparison between old datas and recent datas is difficult because of heterogeneity of old datas ; however, some evolutions of Auvergne flora are noted to relate or not to climate change
- Photography of Auvergne flora at the beginning of XXIe century ; to be a basis for future comparisons
