Invasive Non-native Species (INNS) are plants and animals that have, by whatever means, been introduced into the wild in the UK and are aggressively and rapidly spreading across the country. Many plants that are introduced into gardens and managed landscapes are not classed as invasive and cause no problems to the natural environment. Some, however, take over an area, replacing native vegetation, changing soil types and potentially damaging property, ecosystems and even human health. These species are termed Invasive Non-Natives, and have been called one of the greatest threats to biodiversity in the modern world.
In order to address the problem of INNS, prevent new potenially invasive species becming introduced, and look at ways of reducing the impact of those already established in the wild, a GB Secretariat on INNS has been set up, with national Working Groups at devolved Government levels. These bodies have been working hard to estalish the number and extent of INNS in the UK. To date, 988 non-native species are reported living in Scotland, and whilst the majority of these don't cause any harm to the environment, some can have a massive impact. The main species are detailed below. Japanese Knotweed Rhododendron Himalayan Balsam Giant Hogweed Central Scotland Forest Trust and its partners are working to try to address the spread on INNS across Central Scotland, but before we can do this, we need to know where the problems are. One of the main barriers to an effective control or eradication program is a lack of knowledge about the locations and extent of the main INNS. We are trying to gather data and information from a range of sources, including SEPA and Local Authorities, but you can also do your bit! When your're out and about, if you come across any INNS, let us know! Use the recording form and species ID sheets above to make a note of what you saw, when and where and email it to us.
