Abstract

This thesis investigated impacts of prolonged flooding from mine dewatering discharge on two co-occurring riparian eucalypts. Seedlings of Eucalyptus camaldulensis subsp. refulgens tolerated flooding owing to extensive adventitious root development, while E. victrix displayed few adaptive traits and physiological stress. Mature E. camaldulensis and E. victrix trees growing in anoxic sediments of flooded channels also had reduced physiological function as well as -45% reduction in canopy cover. Overall, impacts of flooding from dewatering discharge can be severe, especially for E. victrix, but are also highly localised and unlikely to affect a significant proportion of the overall riparian vegetation.
