In celebration of His Majesty King Maha Vajiralongkorn Phra Vajiraklaochaoyuhua’s 72nd birthday anniversary, Gulf Energy Development Public Company Limited (SET: GULF) brought volunteers from both the head office and power plants to participate in the “Chulalongkorn Conserving Forests” project. Organized by the Centre of Learning Network for Region (CLNR), Chulalongkorn University, the event involved planting over 2,772 of Yang Na trees on 27 rai of land at the university’s reforestation area in Saraburi Province. This collective effort aims to honor His Majesty the King’s vision of preserving natural resources and environment by expanding green spaces, improving air quality, mitigating urban heat, sequestering carbon dioxide, and fostering environmental stewardship. Mr. Vichai Boonmee, the Deputy Governor of Saraburi Province, Asst. Prof. Dr. Noppadon Kitana, Director of CLNR, teachers, students, locals, and representatives from various organizations joined the initiative. The Yang Na tree holds special significance as the late HM King Bhumibol Adulyadej planted it in the demonstration forest area for conservation at Chitralada Royal Villa on 28 July 1961.
