Abstract
This study aimed to assess the major abiotic, biotic, and anthropogenic factors affecting naturally occurring Rheum L. species in Uzbekistan. Field surveys, visual observations, photographic documentation, and interviews with local communities were conducted during 2024–2026. It was documented that Rheum maximowiczii Losinsk., Rheum cordatum Losinsk., and Rheum macrocarpum Losinsk. are harvested by local communities for food. The major pressure factors identified were the collection of rhubarb leaf petioles and roots, livestock grazing, tourism, and insect damage to seeds. An alternative harvesting method is proposed to promote the sustainable utilization of these species.References
