A report by attorney Read D. Porter that examines coordination on aquatic invasive species (AIS) prevention among the Chesapeake Bay states. The report focuses on prevention-related legal authorities in Virginia, Maryland, and Pennsylvania in particular, and recommends actions to improve regional cooperation both within the existing regulatory frameworks and through potential amendments to state laws and regulations to enhance prevention.
Scientists from the CNRS, the IRD, and the Muséum National d’Histoire Naturelle have just released the most comprehensive estimate to date of the financial toll of invasive species: nearly $1.3 trillion over four decades. Published in Nature(31 March 2021), their findings are based on the InvaCost database, which is financed by the BNP Paribas Foundation and the Paris-Saclay University Foundation’s AXA Chair of Invasion Biology. The annual expenses generated by biological invasions are only increasing, with no sign of any slowing.
One of the basic principles of invasive plant management is early detection. To that end, IPAW is sponsoring a reward program to encourage and provide incentive for citizens of the state to look for and report prohibited invasive plants.
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.
