Approaches and Principles for the Restoration of Tugay Forests in Azerbaijan
Nigar Ahmadova 
Abstract. Tugay (riparian) forests are among the rarest and most functionally important ecosystems in Azerbaijan’s arid and semi-arid lowlands. They provide bank stabilization, microclimate regulation, habitat connectivity, and biodiversity support along the Kura and Araz river corridors. Yet tugay forests have been strongly degraded and fragmented by hydrological regulation, reduced floodplain inundation, groundwater decline, grazing pressure, land conversion, and technogenic impacts. Restoration in this context cannot be treated as ordinary afforestation; it requires re-establishing the coupled river–floodplain–groundwater processes that sustain recruitment and long-term stand persistence. This paper synthesizes national ecosystem assessment findings, official reporting, and peer-reviewed restoration ecology frameworks to produce a restoration framework tailored to Azerbaijan. The core proposition is a driver-based restoration logic linking pressures to geomorphic and hydrological processes, expected ecological responses, measurable indicators, and priority interventions. The paper emphasizes environmental flows, floodplain connectivity, protected-area anchors, and adaptive monitoring supported by remote sensing and field inventories. A set of restoration principles and an intervention sequence are proposed for implementation under realistic constraints, with success criteria aligned to internationally recognized ecological standards and adaptive governance principles.
