Attached is the updated version of Louisa Birch’s amazing booklet about Invasive plants in our area, first printed in 2010 with illustrations by Mary Lord. The 2020 version attached below thanks to Jane Keough, has been reworked extensively and Louisa has several times said that both Karen Bunch and Mary Liz Lewis contributed a lot to the project. Kudos and a big thank you to them and especially to Louisa who has long been a conservation inspiration! I especially want to point out the addition of a chapter on protecting Dublin’s water bodies.
