 The Aleppo pine trees in Aljabel al-Aqdar region were planted in the 1960s and are now mature adults. The oldest tree was established in 1962 and the youngest in 1984, indicating a gap of more than 20 years between them. The average diameter at breast height, dbh, and tree height were typical for similar pine stands in the area, with an average dbh of 29 cm and tree height of 10 m. Thinning may be necessary to ensure optimal growth and high yields from these trees. This article was authored by Atiyah Al-Sanusi and Abduzalim Imali.
