conifer species  shifted upslope 19 m from 1950 to 2016 in the Great Basin, USA, . Reduced winter precipitation caused native annual forbs to recede, resulting in long-lasting and potentially unidirectional reductions in diversity in a Californian grassland . More frequent extreme hot and dry weather between 1966 and 2010 caused a decline in diversity during the post-fire regeneration phase in the Fynbos of South Africa , resulting in shifts towards species with higher temperature preferences . In Italy, Del Vecchio et al.  observed increases in plant cover and thermophilic species in coastal foredune habitats between 1989 and 2012.
