Data of seedling emergence and seedling survival of Mediterranean high mountain scrublands (Juniperus communis and Berberis hispanic) in Sierra Nevada (Spain). 2017-2020

Germination and survival data of Juniperus communis and Berberis hispanica, two species of Mediterranean high mountain scrub, present in Sierra Nevada (Spain). Within the LIFE-ADAPTAMED project (Protection of key ecosystem services by adaptive management of climate change endangered mediterranean socioecosystems; LIFE14 CCA/ES/000612) several restoration actions are being carried out to restore singular ecosystems of the Sierra Nevada high-mountain, such us the high-mountain scrublands (5120 Mountain Cytisus purgans formations of the Habitat Directive). Seeds of Juniperus communis and Berberis hispanica were sowed in two areas of the Sierra Nevada. 210 sowing stations (15 seeds per species) were set up in two contrasting slopes (northeren and southern) of Sierra Nevada. Within each site, several optimal microhabitats were selected: under stone, open ground, wet meadows, under Juniperus, under Genista. The sowings were set up in 2017 and were periodically reviewed (2-3 times a year), to quantify the success of germination and establishment between microhabitats, and thus be able to identify the most propitious places for the regeneration of the juniper in the Sierra Nevada in a scenario of global change.
