Welcome to the Scottish Invasives blog. Invasive non-native species (or INNS) are plants and animals that have been introduced to areas outside their natural range. INNS are currently recognised as one of the greatest threats to biodiversity. The Scottish Invasives blog is intended as an informal forum for those interested in invasive species control. If you wish to contribute, please get in contact. You can click on any of the images to see them at higher resolution.

Several Impatiens species occur in UK, but only one is native. Touch-me-not balsam Impatiens noli-tangere (so called because of its exploding seed-pods) is generally considered to be native only in the English Lake District and mid-Wales. If you find this balsam in Scotland, it will have escaped from a garden. Fortunately it is not invasive, unlike its Himalayan cousin.
