DESCRIPTION:This talk explores how plant diversity has changed over the pas
 t 40 years in the Valsugana Valley of the Italian Eastern Alps\, assessing
  whether these changes have been consistent across different elevation zon
 es. In recent decades\, Alpine valleys have experienced rapid global chang
 es\, including the decline of traditional land management and rural expans
 ion\, with grasslands being particularly impacted. Our findings revealed e
 levation-specific changes in habitat classification\, community diversity\
 , and composition. Many grassland types have transformed into forests or m
 an-made habitats. Species richness patterns varied with elevation: while r
 ichness remained stable at lower elevations\, it increased markedly at hig
 her ones. Turnover dominated at lower elevations\, while nestedness increa
 sed with elevation. Neophytes and thermophilic species increased at lower 
 elevations\, while middle elevations saw a shift from dry grassland specie
 s to nitrophilous and woody species. High elevations experienced a loss of
  mountain species\, replaced by therophytes and geophytes. These findings 
 highlight the significant transformations that Valsugana’s grasslands have
  undergone\, driven by diverse processes along the elevation gradient. Acr
 oss all gradients\, there has been a marked decline in semi-natural grassl
 and species.
