Invasive species: A to our unique biodiversity

The aim of the Toyota Outreach for 2012 is to address one of the ecological challenges in Africa, and the invasion and spread of alien Currently there is an alarming regarding the future of the world’s biodiversity hotspots, given all climate change scenarios an increase in species invasiveness. Africa is currently facing one of the problems with invasive species in the world, with the Biome being a particularly vegetation type in South In South Africa more 660 alien plant species become established in natural and many are known to be contributing to the transformation of once pristine Animal species have established feral populations in the and have a negative impact on species. The most drastic of invasive animal species been recorded in South rivers, where alien such as carp and bass altered habitats and successfully native fauna. Today at 60% of South

Africa’s endemic freshwater are threatened. Thirteen snail have established invasive in South Africa. Forty of the 42 invertebrate crop pests are not to South Africa. This serious concerns about the of our agriculture and ecosystem-related services. For in South Africa, invasions reduced the value of fynbos by over $ 11.75 billion, the cost of lost water due to invasion is estimated to be about $ 3.2 on the Agulhas Plain alone and the net cost of invasion by black amounts to $ 1.4 billion with the to clear alien plant around
$ 60 million per year. These figures of impact have led the African Government to establish the for Water programme with the objective of managing invasive plants to protect water and ensuring the security of water

The Toyota Enviro Outreach, led by Michelle van der Bank from the of Botany Plantbiotechnology in the Faculty of University of Johannesburg, will on April 15 th at the Klipbokkop Mountain and will run until April 27 th. which time several will be visited in the western region with the goal to specimens from a broad of invasive and native taxa and to DNA barcode records for all of them. identification of invasive alien is essential to facilitate planning of containment and management efforts. It is that the most cost-effective is to identify and manage potential species before they To enable this approach the collected and their DNA barcodes be available on the Barcode of Life Base (BOLD) and enable identification of invasive species in Africa. In the future border may be provided with molecular

to identify invasive plants and enabling prevention of prohibited entering South Africa.

This project, which to safeguard our natural wealth and biodiversity loss, is part of an called the International Barcode of (iBOL) project, the biggest genomics initiative ever and led by a team of Canadian scientists.
