Through our work with donors and partners, we are helping to manage the spread of invasive species, a problem that costs the world almost 5% of global gross domestic product or an estimated US$1.4 trillion per year
Millions of the world’s most vulnerable people face problems with invasive weeds, insects, plant diseases and animals, which fundamentally threaten the economic growth supported by sustainable development.
Invasive species disproportionately affect vulnerable communities in poor rural areas, especially in developing countries, which depend on natural resources, healthy ecosystems, trade and tourism for their livelihoods.
Recognising the urgent need for action to protect development and economic growth, we are tackling invasive species around the world. Through a range of projects, knowledge tools and our Action on Invasives programme, we help protect livelihoods and the environment.
We have worked on invasive species for over 100 years, developing practical ways of tackling the biggest threats. Our scientists are world leaders in biocontrol research – an approach that uses invasive species’ natural enemies, like insects, to control their spread.
We produce a range of dedicated knowledge tools on invasive species. These include information on how to prevent the spread of invasive species, how to detect outbreaks and best practice solutions for controlling invasives.
Our invasive species expertise in more detail
Through its global Action on Invasives programme, we are developing and implementing solutions for invasive species around the world, helping to protect 50 million poor rural households.
As experts in biocontrol (the use of living organisms, such as insects or pathogens, to control pest populations), we help farmers control crop pests in order that they can grow more and lose less.
The Invasive Species Compendium is open access and designed to support the work of everyone faced with the identification, prevention and management of invasive species around the world.
CABI has expertise in the prevention, early detection and eradication, and management of invasive species, in centres around the globe including our Swiss centre.

Establishing a digital plant health service in Malawi
Pests and diseases contribute to 40% of food loss leading to food insecurity. Synthetic pesticides are the predominant control method but these are associated with negative environmental and health concerns. The extensive use of chemicals has sparked a renewed interest in Integrated Pest Management (IPM) – an effective combination of control methods and the need for new innovative ways to manage pest and disease outbreaks. There are many digital systems that have been developed to identify, monitor, manage, control and predict outbreaks of a large number of pest and disease species. These systems provide useful information to aid decision-making and timing of integrated pest management strategies. By building on the successes of existing systems and data assets, this project aims to establish a digital agricultural plant health service for efficient pest and disease management in Malawi that will benefit over 100,000 farmers.
Biological control of Old Man’s Beard
Clematis vitalba is a fast-growing vine that produces vast quantities of seeds and grows intensely as thickets over trees, shrubs and other vegetation. Due to its rapid growth rate and ability to form large clumps, the plant can quickly outcompete native biodiversity and is dangerous to forests which is why Clematis vitalba is classed as one of New Zealand’s most invasive alien plants. Current control methods include mechanical removal and herbicides. However, this project is investigating the potential of biological control using fungi from its native range to help control the weed.
Biological control of tree of heaven
Tree of heaven, Ailanthus altissima, is a deciduous tree native to north-east and central China and Taiwan. It was brought to Europe and North America as an ornamental, but became invasive and is now an invasive species of concern in many countries, including Canada. Once established, tree of heaven is difficult to control, with mechanical and chemical options being limited and expensive. Since 2020, CABI has been working with partners to coordinate options for biological control of tree of heaven in Canada.
