Himalayan balsam awareness week


The 16 – 24 May is Himalayan balsam awareness week. Run by the UK’s Inland Waterways Association, it promotes awareness and understanding of the invasive weed that’s blighting our landscape.

See some of our latest tweets on @cabi_news and latest posts on our Facebook page.

Find out more about the awareness week by visiting the Inland Waterways Association’s campaign page. It includes information on how to identify it, what to do if you come across it and how to get involved in getting rid of it.

The 22 May is also the International Day for Biological Diversity, so check out the CABI website to learn about selected projects that help protect natural systems and books from our publishing programme that you can win.
