Root Traits and Erosion Resistance of Three Endemic Grasses for Estuarine Sand Drift Control

In southern Taiwan, rivers sporadically cease to flow and dry up in winter. The exposed riverbeds are very vulnerable wind erosion. strong northeast monsoon often induces serious estuarine sand drift fugitive dust, which cause damages agricultural crops, human health infrastructures. Giant reed (Arundo formosana), common (Phragmite australis) the wild sugarcane (Saccharum spontaneum) pioneer grass species estuary areas. They have great potential reduce erosion control windblown dust on lands. Nevertheless, their root traits, biomechanical characteristics resistance not been investigated. this research, traits were investigated utilizing hand digging technique WinRHIZOPro System. Root pullout tensile strength estimated using vertical tests. Wind tunnel tests executed evaluate six-month-old plants. results demonstrated that growth performance functional of S. spontaneum superior those A. formosana P. australis. Additionally, anchorage ability plants notably greater than australis Furthermore, showed is remarkably higher This study demonstrates australis, considering ability, resistance. Taken together, our suggest favorable for riverbed planting, while A.formosana applicable riverbank planting These results, together with data acclimation grasses waterlogged soils brackish waters, provide vital information designing strategies ecological engineering control.
