Abu Dhabi, UAE – In a remarkable advancement, the Environment Agency – Abu Dhabi (EAD) and the International Center for Biosaline Agriculture (ICBA) have completed the UAE’s inaugural population genomics study focused on the Ghaf tree (Prosopis cineraria). This insightful research reveals vital genetic information that could reshape conservation strategies for this essential desert species and bolster climate-adaptive ecosystems across the nation.
The Ghaf tree, honored as the UAE's national tree, plays an indispensable role in the local ecosystem. Its deep-root systems stabilize sandy terrains, enrich soils, and create habitats for various desert wildlife. Culturally, the Ghaf is a significant symbol of endurance and life amid the arid landscape. Although previously limited, scientific knowledge of its genetic diversity has now vastly expanded.
Researchers from EAD’s Plant Genetic Resources Centre and ICBA conducted comprehensive whole-genome re-sequencing on Ghaf specimens sourced from diverse ecological settings in the UAE, such as sand dunes, valleys, coastal regions, and mountainous areas. Their investigations have unveiled four genetically distinct groups, notably one exclusive lineage found in the foothills of the Hajar Mountains and Abu Dhabi’s Jebel Hafeet National Park, offering fresh avenues for specific conservation measures.
The outcomes of this research serve as a pivotal scientific basis for various initiatives. The genetic data will direct national planting programs of Ghaf trees, seed preservation projects, and efforts to restore habitats. Additionally, insights into environmental adaptability and response to stress will inform the development of sustainable strategies in areas facing desertification and saline conditions.
Additionally, digital tools have been designed to illustrate genetic relationships among different Ghaf populations. These interactive resources can assist conservationists and planners in making informed decisions to protect biodiversity, ensuring ecological stability within the demanding desert habitats of the UAE.
By integrating advanced genomic techniques with impactful conservation planning, this research paves the way for safeguarding native species in arid regions. It represents a significant step forward in the UAE’s commitment to sustainable biodiversity management, underscoring the vital role of scientific innovation in preserving our natural legacy for generations to come.
