SCOPING REPORT, EIA and EMP OF THE PROPOSED ERADICATION OF INVASIVE ALIEN FISHES FROM SELECTED RIVERS IN THE CAPE FLORISTIC REGION
The introduction of invasive alien fishes to rivers of the Cape Floristic Region (CFR) in the late 1800s and early to mid 1900s, primarily for angling purposes, has had major impacts on the indigenous aquatic faunas. Almost all the fish species of this region are now classed in threatened categories in the IUCN red data list (http://www.iucnredlist.org), with invasive alien fishes highlighted as having the major impact in almost all species assessments (Appendix 1). Eradication of invasive alien fishes is thus a critical component of conservation plans for endangered fish species in the CFR. Section 28 of NEMA places an obligation on CapeNature to remedy degradation of environments harmed by alien and/or invasive species. This proposed pilot project demonstrated successful invasive alien eradication techniques and consequent recovery of natural ecosystems containing indigenous fishes. The results can be used to provide the basis for the development of protocols for addressing similar problems in other rivers.
