Summary
In South Africa, many alien tree and shrub species have become invasive, with resultant detrimental impacts on native fynbos plant communities. Various (usually uncoordinated) eradication programmes by various organizations and landowners have been implemented on the Cape Peninsula Mountains in an attempt to control invasives but records of outcomes are rarely kept. The aim of this study was to make an assessment of current distribution and densities of alien populations on permanently marked sites surveyed in 1959/60, and to assess the success of control measures.
Fourteen invasive woody taxa were recorded (4 Pinus species, 3 Hakea species, 5 Acacia species, Eucalyptus spp. and Cape wattle Albizia lophantha) in the sampling sites. Of concern was that Monterey pine Pinus radiata (10% occurrence in 1959/60, 24% in 1989/90) and rooikrans Acacia cyclops (20% occurrence in1959/60, 26% in 1989/90) showed significant increases in frequency. Neither in the past was considered particularly aggressive invasives in the Peninsula Mountains.
