This was the second mass-clearing hack at the Greater Princess Vlei Conservation Area hosted by the Princess Vlei Forum and Botanical Society Kirstenbosch. Clearing invasive alien plants is critical to enable regrowth and restoration of indigenous species.
A seasonal seep between the two vleis was selected for clearing. This area burnt in summer 2019/2020 and a surprising diversity of species have been found germinating from the seed bank underground. It is a priority to clear this area as the habitat has great rehabilitation potential.
The seep was invaded with an impenetrable thicket of White Poplar (Poplus alba), Black Alder (Alnus glutinosa), and Port Jackson (Acacia saligna). The youngest plants were 1 year old seedlings, and the largest were 5 meter tall Port Jacksons.
