Abstract

Streams in urbanised catchments are subjected to a multitude of anthropogenic impacts leading to impaired nutrient retention
capacity. This research addressed nutrient retention by stream vegetation and banks features, and explored the spatial and
temporal dynamics of nutrient retention by vegetation and the impact of its abundance under different hydrological conditions.
The results showed the capacity of certain features (roots mat) to consistently reduce nutrient (nitrate and ammonium)
concentrations during high base flows and emphasized the importance of selectively planting species for which nutrient gross
uptake surpasses release processes, resulting in greater capacity to minimise catchment nutrient export.
