The potential use of storm water and effluent from a constructed wetland for re-vegetating a degraded pyrite trail in Queen Elizabeth National Park, Uganda

► Storm water and effluent from a constructed wetland rises pH in a pyrite trail. ► High pH enhances vegetation decolonization and restoration. ► Pioneer colonizing plants are Cynodon dactylon and Typha latifolia. ► Plants with high tolerance to high metal concentrations. ► Restoration minimizes pollution of Lake George in Uganda.
