Aseer: Aseer Region is home to one of the Kingdom's richest biodiversity landscapes, with its beauty particularly evident during winter, when highlands and plains transform into vibrant ecosystems teeming with diverse plant life and wild trees. During the season, almonds, peaches, and plums thrive in the Aseer highlands, while the Tihama area experiences extensive vegetation growth with the onset of early spring. The region's varied elevations and environments-from mountain peaks and valleys to coastal zones-support distinctive local species such as acacia, tamarisk, desert shrubs, and flowering wild plants that benefit bees through honey and pollen production.
According to Saudi Press Agency, Tihama also witnesses the flowering of tropical trees, including mango, making winter a critical season for vegetation renewal and ecological balance in the region. Environmental expert Saeed Al-Suhaimi highlighted that this natural wealth faces mounting environmental challenges, most notably declining rainfall and reduced fog levels, both of which are essential for sustaining plant life, particularly in the highlands. These factors have negatively affected several native species, especially juniper trees.
He added that excessive logging, soil erosion, land fissures, and environmental degradation have weakened the ecosystem. Urban expansion and land reclamation have also resulted in the loss of large areas of vegetation cover. In addition, the spread of invasive plant species has further disrupted ecological balance by competing with native plants.
Al-Suhaimi noted that recurring droughts have increased pressure on vegetation, leading to reduced reliance on natural pastures despite their continued presence in many mountainous areas, which has affected livestock and their environmental role. He stressed that, contrary to the perception that Aseer's forests require little intervention, the region needs long-term protection and rehabilitation programs. Although current efforts remain in their early stages, he said, they represent an important step toward preserving this environmental heritage and ensuring its sustainability for future generations.
