The Centre for Biological Control (CBC) was represented at the 45th Annual Invasive Species Management Symposium by a contingent of 10 students and 2 staff members. It took place at the University of Venda, in Limpopo from the 3 – 6 July. The journey to the symposium took the team across to one of the north-most reaches of the country, Thohoyandou, where they met a number of delegates from different backgrounds. The symposium was attended by government departments like the Department of Environmental Affairs (DEA), Department of Agriculture Forestry and Fisheries (DAFF), municipalities and institutes such as SANBI, who organized the event. Researchers and students from a number of academic and research institutions such as the Agricultural Research Council (ARC), Centre for Agriculture and Biosciences International (CABI), Stellenbosch University, University of the Witswatersrand, and the University of Venda were also in attendance.

The theme of the conference this year was “Invasions trans-boundary” where most of the keynote talks addressed the problem of the spread and movement of invasive species across regional and international boundaries. It was identified that there is a need for stronger biosecurity measures, as well as to enforce them once they are in place. Furthermore, it was highlighted that there is still a knowledge a gap between research and implementation. This is a recurring problem that has been discussed over the years during this conference. A round table discussion allowed implementation managers and officers to voice out the disjoint between research and implementation,  the input from the round table discussion will be used to write a chapter in the a book by van Wilgen and colleagues.  It is hoped that this will help contribute to bridging the gap that exists, and therefore lead to better management of all invasive flora and fauna in South Africa and the region at large. The team from the CBC did well in representing Rhodes University, where one of the speakers got recognition for having delivered the best speed talk at the conference - well done Nompumelelo Baso! We are very proud of her. The team also had the opportunity to visit  Kruger National Park during on their way home.
