Scottish Invasive Species Initiative.
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
