This dataset represents the SANBI-INR Invasive Alien Plants (IAPs) layer integrated with other IAPs data from various sources i.e., the Socio-Economic Benefits of Ecological Infrastructure (SEBEI), Cape Nature, Water Information Management System (WIMS), Aurecon and the National Invasive Plants Survey (NIAPS). The Berg-Breede IAPs density layer was developed using a conditional classification approach. This layer is one of the outputs from the “Development of a semi-quantitative protocol for mapping woody invasive alien plant species” study and was developed as part of SANBI’s Ecological Infrastructure for Water Security (EI4WS) Project. The dataset represents the percentage of IAPs density in the Berg-Breede demonstration catchment at a 10m spatial resolution.

For further details on the technical approach followed in developing the layer refer to the following technical report for the project.
