Abstract This paper assesses progress towards the control of biological invasions in 18 protected areas (PAs) covering 677 584 ha Cape Floristic Region (CFR), and whether has been sufficient to achieve Target 6 Kunming-Montreal Global Biodiversity Framework. We used eight indicators for assessing inputs (quality regulatory framework, money spent planning coverage species areas), outputs (species treated), outcomes (effectiveness area treatments) management. The estimated over 13 years (2010–2022) was ZAR 976 million, or 75 million per year. Management plans PAs were assessed as adequate 78.5% area, but only six out 226 regulated invasive had species-specific place. A total 567 alien occurred CFR’s PAs, which (i.e. that be controlled), 126 (55.8%) received some Spending highly skewed, with 60% all funding on trees shrubs genus Acacia . efforts reached 24% land within areas, higher national parks (60%) than provincial nature reserves (9%). effectiveness either permanent, effective partially 29 (20 due control), ineffective 25; remainder, there no management could not evaluated. conclude made respect controlling CFR, insufficient declining remains a significant barrier To increase efficiency, it will necessary secure additional from more diversified sources, make use prescribed fire, regularly monitor
