Declines in plant health and increased mortality in MTEs associated with drought have been widely documented  . Remote-sensing studies show drought-associated mortality in post-fire vegetation regrowth in the Fynbos of South Africa , reduced canopy health in forests within MTE zones of South Africa  and declines in canopy water content in the forests of California . Several studies reported climate-associated responses of dominant or charismatic species. High mortality in the Clanwilliam cedar tree between 1931 and 2013 occurred at lower, hotter elevations in the Fynbos of South Africa . Drought reduced growth and increased mortality of the holm oak, Quercus ilex, on the Iberian Peninsula of Spain . Portuguese shrublands experienced losses of many deciduous and evergreen oak species, and an increasing dominance of pyrophytic xeric trees . The 2012-2015 drought in California caused high-canopy foliage dieback of the giant sequoia  , increased the dominance of oaks relative to pines as a result of the increased water deficit, and led to large-scale tree mortality due to interactions of drought and insect pest outbreaks .
