Toyota Enviro Outreach led by Prof M van der Bank Botany


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

out-competed native fauna. at least 60% of South Africa’s freshwater fish are threatened. snail species have invasive populations in South Forty of the 42 major invertebrate pests are not native to South This raises serious about the future of our agriculture and services. For example, in South invasions have reduced the of fynbos ecosystems by over $ billion, the total cost of water resources due to invasion is to be about $ 3.2 billion on the Agulhas alone and the net present cost
of invasion by black wattles to $ 1.4 billion with the cost to alien plant invasions $ 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 Data (BOLD) and enable rapid of invasive species in South In the future border checks may be with molecular tools to invasive plants and animals prevention of prohibited species 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.
