BBC Radio 4 – Squirrels & Knotweed

Last week I was delighted to share some of my knowledge of exotic and invasive species on national radio, thanks to an invitation by Kat (@harpistkat) and Helen Arney (@helenarney) to appear on their series “Did the Victorians Ruin the World?”

In the episode I talk about the introduction of the grey squirrel to Victorian Britain and how negative attitudes towards native red squirrels rapidly changed thanks to the new arrivals. I also discuss the introduction of Japanese knotweed, which was once advertised as an ornamental and desirable addition to every garden.
