The restoration of the endangered Sambucus palmensis after 30 years of conservation actions in the Garajonay National Park: genetic assessment and niche modeling

A genetic analysis of the endangered Canary Islands endemic Sambucus palmensis reveals that 30 years of conservation efforts, primarily through translocation using cuttings, have successfully increased population heterozygosity while preserving unique genetic diversity. The study, conducted in Garajonay National Park (La Gomera), genotyped 402 samples from restored and natural populations using seven microsatellite markers. While clonal reproduction remains prevalent due to propagation methods, the Liria population emerged as a critical genetic reservoir. Species distribution modeling identified new suitable reintroduction areas, guiding future conservation strategies. The findings underscore the effectiveness of targeted reinforcement while highlighting the importance of preserving native genetic variation.
