Here you'll find presentations, activities, worksheets, quizzes, crafts, puzzles and games, all themed around invasive alien species and the river environment which can all be downloaded and shared. There is an introductory presentation to start you off and all activities have notes and answer sheets to help you along – so you don’t need any prior knowledge to use and enjoy them. The activities can be done in groups e.g. a school class but many can be completed individually at home or in the outdoors

Biological invasions are a major threat to ecosystems, biodiversity, and human well-being, resulting in ecosystem degradation and causing economic costs in the multi-trillions of euros globally. A study led by McGill University sheds light on the stark economic cost resulting from biological invasions in the European Union (EU). Most invasive alien species are not adequately assessed for their actual and potential economic impacts therefore most cost estimates are grossly underestimated, say the researchers. To fill this gap, the team quantified the economic costs of biological invasions to the European Union, while estimating future invasion costs using predictive models.

The Be Plant Wise campaign, launched by Defra and the Scottish Government, is designed to raise awareness among gardeners, pond owners and retailers of the damage caused by invasive aquatic plants and to encourage the public to dispose of these plants correctly. We have developed resources with advice for gardeners and pond owners and are working closely with retailers of aquatic plants to provide information in stores. These pages contain the detailed information you need to Be Plant Wise.

Invasive species can have severe impacts on ecosystems, economies, and human health. Though the economic impacts of invasions provide important foundations for management and policy, up-to-date syntheses of these impacts are lacking. To produce the most comprehensive estimate of invasive species costs within North America (including the Greater Antilles) to date, we synthesized economic impact data from the recently published InvaCost database (see related research article: InvaCost, a public database of the economic costs of biological invasions worldwide (Sep 8, 2020).
