Help us tackle invasive species across Wales
What are invasive non-native species?
Invasive non-native species have been introduced by humans, intentionally or unintentionally, beyond their natural range. Their spread threatens native biological diversity and can cause damage to the environment, the economy, our health and the way we live.
Invasive non-native species (INNS) are also referred to as Invasive Alien Species (IAS). Here we refer to them as invasive species.
Wales Resilient Ecological Network
The Wales Resilient Ecological Network (WaREN) are establishing a framework for tackling invasive species across Wales. We are developing linkages between stakeholders that are taking action on invasive species, with existing projects and Local Action Groups in Wales. Local Action Groups focus on reducing the risks and impacts of invasive species in their local area, for example through direct management.
WaREN will also increase public engagement to raise awareness of invasive species through effective science communication and sharing best practice.
Why is this important?
Invasive species are one of the main threats to biodiversity globally. They have negative impacts on our environment. For example:
- Competition for resources such as light and water
- Predation on native species
- Carrying new diseases
- Hybridisation - where invasive species breed with closely related native species
Invasive species can also impact on human health and the economy. For example, they were estimated to cost Wales at least £125 million in 2010, a cost which is likely to be increasing.
