Green Invasion: Destroying Livelihoods in Africa [Video]
CABI, together with Tmax Productions, have produced a video called the ‘Green Invasion – Destroying Livelihoods in Africa.” The short film (approx. 7mins long) details how invasive weeds are impacting on the lives of rural communities in East Africa. Although a large number of non-native species have become invasive in the region, this film focusses on…
Lakes poisoned to halt topmouth gudgeon invasion
Several lakes in Hampshire are being poisoned in a bid to control topmouth gudgeon (Pseudorasbora parva), an invasive non-native fish first introduced to Britain in the 1980s which has become more widespread in recent years. The fish, native to Asia, has spread across much of Europe in recent decades, travelling along waterways and facilitated by…
The urgent need for evidence based policy in invasive species management
Hundreds of invasive species experts gathered last week, 23-27 October, in Qingdao China at the 2nd International Congress on Biological Invasions. High on the agenda was how policy makers can respond to the accelerating risk posed by invasive species as international trade increases and climate change opens up new opportunities for invasion. In a session…
CABI welcomes EU action against invasive species
CABI welcomes action that the EU has recently taken (September 9, 2013) to protect member states against the adverse impacts of Invasive Alien Species (IAS). The draft Regulation on the prevention and management of the introduction and spread of IAS will help to coordinate management and preventative measures across the whole of the EU, leading to…
The advance of the Asian hornet creates a buzz in the UK media
Some of the species that are included in our open-access Invasive Species Compendium are well known to the general public, for example Japanese Knotweed. Others are more obscure, and I had never heard of the Asian Hornet, Vespa velutina, until I edited the datasheet about it earlier this year. I was therefore interested to hear…
Use them and lose
Is promoting the utilisation of invasive non-native species for commercial or other uses e.g. as a feed for livestock, use as a fuel or to produce biogas, a help or a hindrance to their control? A view from Arne Witt, CABI Regional Coordinator, Invasives (Africa & Asia): Promoting the utilization of any invasive non-native species…
Invasive species catch a wave
Over two years have now passed since the Tohoku earthquake rent the seafloor 40 miles off the coast of Japan. The 9.03 magnitude quake – the largest in Japan’s history – triggered a staggeringly destructive tsunami which cost the lives of over 15,000 people. Aside from the human tragedy of the disaster, the tsunami has…
Rusty Solutions for a Prickly Problem
The state of Queensland has got an alien thorny invader: Prickly acacia, or in scientific terms Acacia nilotica subspecies nilotica. Prickly acacia is a shrub or small tree which belongs to the plant family Leguminosae, subfamily Mimosoideae, a family which also accommodates the sensitive plant Mimosa pudica, well-known as a curiosity house plant. The prickly…
Alien Battlefield
Recent articles in Science, the NY Times and Nature have suggested that we should embrace invasive species and the resultant “novel ecosystems” and that those that do battle with such species are verging on xenophobic. This is a common cycle in many fields and I’m told that a discussion thread is considered closed once a…
The Nagoya protocol and biological control by Matthew Cock
Since 2009, I have worked with the Global Commission on Biological Control and Access & Benefit Sharing of the International Organisation for Biological Control to raise awareness of the issues relating to biological control which may be affected under the Convention on Biological Diversity’s access and benefit sharing protocol which was finally agreed at COP10…
