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.

For the first time, an invasive brown treesnake population has been found on Cocos Island, an 83.1 acre atoll located 1.5 miles off the southwest coast of Guam. The brown treesnake was a major contributor to the loss of nine of 11 native forest birds and significant population declines of several native lizards, bats and other bird species on Guam. They now pose a threat to the wildlife of Cocos Island. Guam Department of Agriculture Division of Aquatic and Wildlife Resources is working with partners to better understand how many brown treesnakes are on the island and the best way to remove them.

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.

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.

Invasive species are well known for their huge ecological costs, but they also bring a massive economic burden with sociological, environmental and health impacts. New research led by the University of Aberdeen and the University of Auckland in collaboration with CNRS, France has established that invasive species have cost the New Zealand economy almost $100 billion in the last 50 years. While damage costs remain high, this total includes spending far more than most other countries on pre and post-invasion management techniques relative to its GDP.

The spread of invasive plant species has serious consequences for Africa. Toxic weeds and harmful shrubs significantly shrink rangelands and lower the productivity of major grain foods such as maize (in some instances by up to 45%). This briefing highlights the significance of earth observation (EO) data for the development of tools and strategies to curb the increasing spread of invasive species.

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.
