Invasive Non-Native Species Group

Invasive Species

Invasive Non-native Species (INNS) are plants, animals, fungi and microorganisms which have been introduced to parts of the world where they would not naturally be found. They have the ability to spread causing damage to the environment, the economy, our health and the way we live. INNS are the second greatest threat to biodiversity after habitat loss and fragmentation. INNS have been estimated to cost the UK economy at least £1.8 billion pounds annually, they mainly affect farming and horticultural sectors but can affect transport, construction, recreation, aquaculture and utilities.

Wales Invasive Non-native Species Group

The Wales Invasive Non-native Species Group was formed to help identify INNS priorities and resolve issues relevant to Wales. The group acts as a source of expertise on INNS in Wales. The group generally meets three times a year. It’s work programme is focused on action under 5 key topic areas – promoting action, raising awareness, sharing best practice, information exchange and expertise. Membership includes representatives from Wales Biodiversity Partnership, Academia, GB Non-Native Species Secretariat, Local Authorities, Natural Resources Wales, Public Health Wales, Wales Environment Link, Welsh Government, the Welsh Local Government Association and Utility companies.

Great Britain Invasive Non-native Species Strategy

The GB Invasive Non-native Species Strategy provides a framework on how to minimise the risks posed by INNS. The strategy sets out key aims and actions for addressing the threats posed by INNS. The current strategy covers 2015 to 2020 and replaces the first strategy published in 2018.

  1. GB Invasive Non-native Species Strategy

Non-native species records help us understand how many INNS species are present in Britain, and the rate at which they are spreading. Everyone can provide useful biological records of non-native species, and with the development of online recording sites and smartphone apps it is now easier than ever. Sightings of INNS should be reported in accordance with GB Non-native Species Secretariat guidance.

Some species are highly invasive and are classed as ‘Alert Species’. It is particularly important to report these species if sighted.

View the distribution of Invasive Non-native Species of interest to Wales on the National Biodiversity Network Atlas Wales – Invasive Non-Native Species (INNS) Portal.

The INNS Portal includes over 300 terrestrial, freshwater and marine species of interest to Wales and allows species occurrences and distribution to be searched for and downloaded individually or collectively by list.Species include those listed under EU and national legislation and those of policy and practical interest, including those identified as Wales Priority Invasive Non-Native Species for Action by the Wales Biodiversity Partnership INNS Group.

Action is taking place across Wales and GB by various groups, projects and organisations to help reduce the risks and impacts associated with invasive non-native species.

There are a number of Local Action Groups active in Wales tackling invasive species including the Dee Invasive Non-Native Species Project. The project is a catchment-wide partnership initiative which aims to coordinate the control and monitoring of invasive non-native species (INNS) within the Dee catchment to ensure a joined-up approach to INNS management is delivered.

The Wales Invasive Non-Native Species Group maintains a list of Priority Species for Action in Wales. This list can be used to help focus action on INNS in Wales. Species are listed under three categories – prevention priority species (those not yet in the wild but likely to arrive), management priority species (those present in the wild in low numbers) and long-term management priority species (those established in the wild)

Biosecurity is about lowering the risk of introducing or spreading INNS (and other harmful organisms such as disease) in the wild.

When visiting sites with water follow these steps:

  • CHECK all clothing and equipment
  • CLEAN clothes and equipment on site
  • DRY thoroughly dry equipment and clothing

WaREN promotes biodiversity and ecosystem resilience through the development of a pan Wales approach for the effective sustainable management of INNS in a strategic, prioritised and joined up way.

This new innovative approach will provide opportunities to collectively work together by increasing engagement, participation and co-operation with a wide range of public, private and third sector stakeholders, making a real impact on effectively addressing the problem of INNS on the environment, economy and wellbeing of people in Wales.

In this first developmental phase, supported by Welsh Government funding, WaREN aims to:

-Develop a ‘Pan Wales INNS Framework for Collaboration’, a sustainable collaborative strategy for Wales to tackle INNS in a co-ordinated way.

-Scope a toolkit to provide information and guidance to support stakeholders work on the ground and to enable funders to make evidence-based decisions.

-Produce a sustainable funding mechanism overview which will identify funding streams and opportunities

A WaREN Project Board has been established with membership including Welsh Government, Natural Resources Wales, Wildlife Trust of South and West Wales, Welsh Water, Wales Biodiversity Partnership and the DEE INNS Project, along with GB NNSS and Land Managers as special advisors. Strategic steer is provided by the WBP INNS Group.

How to get involved? We are keen to engage with organisations, businesses and community groups with an interest in INNS, including holding a series of regional workshops. Please get in touch with us via contact us.
