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

Advancing the Risk Analysis for Alien Taxa (RAAT) framework

NeoBiota, Journal Year: 2025, Volume and Issue: 97, P. 319 - 324

Published: March 4, 2025

The Risk Analysis for Alien Taxa (RAAT) framework was developed to collate scientific information and interpret it in the context of South African regulations on biological invasions. Feedback from past four years has shown RAAT be a valuable tool making evidence-based, transparent recommendations, but one that can improved. We describe changes made creating v2.0. note several issues we suspect will apply many similar processes, namely need i) clarify descriptions; ii) remove superfluous questions; iii) add questions fully justify recommendations. also stress what v2.0 does not do—the summarise management best practices nor it, or Africa’s regulatory lists, provide sufficient prioritise resources. strongly recommend explicit feedback mechanisms are set up ensure such frameworks improved over time.
