What makes Saxaul trees unique?

Saxaul trees, commonly known by their Arabic name Al-Ghadha, produce seeds only as they become drier. The saxaul can survive for months without water and thrives where temperatures soar to 58 degrees Celsius (136 F). Guinness World Records recognized Saudi Arabia’s Unaizah park as the world’s largest saxaul botanic garden, stretching over 172 sq km (66.41 sq miles). As part of the Saudi government’s green initiative to reduce carbon emissions, pollution, and land degradation, the Al-Ghadha environmental association plans to plant 250,000 drought-resistant Saxaul trees during 2022 in Unaizah.
