Invasive aliens
A Practical Guide to Managing Invasive Alien Plants by WWF
This practical guide aims to empower land users—including landowners, land managers, and contractors—within the Cape Floral Region to understand the threat posed by invasive alien plants (IAPs) and effectively manage them on their land. The guide was developed by WWF South Africa in collaboration with the Agricultural Research Council, the City of Cape Town, Corteva Agriscience, the Department of Environment, Forestry and Fisheries, LANDWORKS, the Fynbos Trust, and NCC Environmental Services. It provides a detailed set of instructions on how to approach the clearing of IAPs, recognising that management methods often differ depending on the local context. The guide also serves as a first-stop resource that can be adapted to local conditions while providing useful references to additional information and resources from a range of other sources.

Impact of Mechanical Removal on Trout in SA Streams
Invasions by non‐native species can compromise the conservation value of otherwise pristine headwater streams. While both developed and developing countries recognize this threat, few of the latter have suitable budgets to implement control programmes.
