Synthesis Report of the UNEP/GEF Removing Barriers to Invasive Plant Management in Africa (RBIPMA) Project, implemented in four African countries (Ethiopia, Ghana, Uganda and Zambia) between 2005 and 2010.
CABI scientists have conducted the first comprehensive study on the economic impact of a range of Invasive Alien Species (IAS) on Africa's agricultural sector, which they estimated to be USD $3.6 trillion a year. This is equivalent to 1.5 times the Gross Domestic Product (GDP) of all African countries combined – or similar to that of Germany. The average annual cost of IAS per country was USD $76.32 billion. Full details of the cost for individual countries are outlined in the paper published in the journal CABI Agriculture and Bioscience.
The Galapagos National Park Directorate (GNPD) is partnering with CABI and the Charles Darwin Foundation (CDF) to help protect the iconic Galapagos Islands from an invasive blackberry (Rubus niveus). This non-native plant was introduced in 1968 and is causing serious problems for local biodiversity and agriculture. It is now considered one of the worst weeds affecting the islands.

The Invasive Carp Regional Coordinating Committee (ICRCC) announced the release of its 2022 Invasive Carp Action Plan, a comprehensive portfolio of 60 projects focused on Great Lakes protection. The Action Plan serves as a foundation for the work of the ICRCC partnership — a collaboration of 28 U.S. and Canadian federal, state, provincial, tribal, regional, and local agencies.
The Invasive Carp Regional Coordinating Committee (ICRCC) is pleased to announce the release of its 2023 Invasive Carp Action Plan, a comprehensive portfolio of more than 50 projects focused on Great Lakes protection. The action plan serves as a foundation for the work of the Invasive Carp Regional Coordinating Committee partnership, a collaboration of 26 U.S. and Canadian federal, state, provincial, tribal, regional and local agencies.

USGS scientists, in collaboration with partners, are conducting risk assessments and life history research to enhance the ability of agencies to manage Invasive carp to minimize their influence and spread.
Great Lakes Commission; Invasive Mussel Collaborative.
The Invasive Mussel Collaborative announced today that it has released a new strategy to reduce invasive mussels and their negative impacts. The Strategy to Advance Management of Invasive Zebra and Quagga Mussels is intended to drive investments, policy, and research around invasive mussels across the Great Lakes region and beyond. Since their initial discovery in 1989, zebra and quagga mussels have had dramatic impacts on the Great Lakes ecosystem and economy, including changes to the food web, degrading fish habitat, interfering with drinking water systems and damaging tourism and recreation economies. Today, these mussels continue to spread to new water bodies across the U.S. and Canada.
Most invasive insects are hidden away for the winter, but you still might encounter them when you split wood, move outdoor furniture indoors, or admire evergreen plants while on a hike. Learn more about invasive pests you may come across and how to report them.

This guide is intended to assist with identification of invasive plants and provide information on controlling these problem plants. Included are both non-chemical means of control as well as information on proper use of herbicides where chemical controls are needed. The choice of control measure depends on the size and nature of the infestation. If dealt with early enough, invasive plant problems can often be eliminated by non-chemical methods. However, a herbicide-based approach may be required to control an infestation that has become well established or widespread.
This interactive Lucid key and accompanying fact sheets provides a resource that can help those who wish to identify species of concern and to undertake management efforts to minimise their impact. Provides information for 100 of the most important invasive plant species in the East African Region.
This book is part of the CABI Invasive Series, which addresses all topics relating to invasive species, including biosecurity surveillance, mapping and modelling, economics of invasive species and species interactions in plant invasions. This book specifically aims to examine the nexus of climate change and biological invasions, and the resulting impacts, and to identify means to reduce the vulnerability and increase the resiliency of managed and unmanaged ecosystems. (Full-text is available for employees on the USDA network).
The Mediterranean Sea is being invaded by hundreds of fish, jellyfish, prawns and other marine species from outside the region. More than 1 000 non-indigenous species have been identified in the Mediterranean and the Black Sea. Over half have established permanent populations and are spreading, causing concern about the threat they pose to marine ecosystems and local fishing communities.
“Climate change and human activities have had a profound impact on the Mediterranean and the Black Sea,” says Stefano Lelli, a fishery expert for the eastern Mediterranean working for the General Fisheries Commission for the Mediterranean (GFCM). This regional fisheries management body, established by FAO, is leading efforts to promote sustainable fisheries and aquaculture in the Mediterranean and the Black Sea.
