The Aquarex Elm is a keystone woodland tree of Geba. It bears smooth pale bark that beads and sheds heavy rainfall to prevent saturation. The species coppices vigorously from cut stumps, stabilizing soils along rivers and floodplains and supporting pollinators and small woodland fauna such as the Imperial Striking Wasp. Its timber is dense, water-resistant, and widely used for construction and craft. The elm tolerates mild seismic activity and aids recovery following disturbance.
