Plant dieback in Mediterranean shrublands under 2014 extreme drought (Alicante, Spain)

Field data from four Mediterranean shrublands monitored during an extreme drought in 2014 (hydrological year) in SE Spain. Data are plant dieback of the total plant community and main plant biotypes (shrubs, subshrubs and grasses), vegetation structure attributes (phytovolume, plant height, LAI, and sizes of patch and inter-patch areas), soil properties (soil depth and soil surface cover types) and water availability indicators (soil moisture and environmental variables).
