Heath Star Moss Sketchbook study

Posted on 7th January 2022 in botanical terms, Current projects and news

Heath star moss is one of three invasive species I’ve just illustrated for FOR in Sweden. In this case, the moss is an unwelcome invasive in Iceland, where it outcompetes other mosses and affects the delicate balance of existing ecosystems.

Comparing Periwinkle Species

Posted on 27th November 202027th November 2020 in Botany: Telling species apart

Periwinkle species feature on the list of a recent job of invasive plants I’ve completed for FOR Sweden.

Invasive & Japanese Knotweeds: Telling species apart

Posted on 3rd May 20193rd May 2019 in Botany: Telling species apart

Invasive and Japanese knotweeds are incredibly successful plants. Originally from Japan, China and Taiwan, they escaped from ornamental gardens, and have become established across the UK. They’re especially common in urban and brown-field habitats, and love railway embankments and the damp soils of water ways. One of the most difficult aspects of controlling them is […] Read more

Many times, the reason a plant or animal is causing problems within an ecosystem is because it doesn’t belong in that system. It hasn’t evolved in equilibrium with the other species there, and thus out-competes them. […] Read more
