The INNSA registration scheme

The Invasive Non-Native Specialists Association is the industry body for companies involved in the control and eradication of invasive non-native species. Membership demonstrates a professional knowledge and understanding of invasive species and the methods by which they are best eradicated. Registration with INNSA provides members with a recognised accreditation backed up by a comprehensive insurance scheme.
