Invasive non-native species cost Wales over £125 million a year, damaging habitats, threatening biodiversity, and impacting communities. Despite legal protections, public awareness remains low. Through the WaREN II programme, North Wales Wildlife Trust needed a campaign that could raise awareness, shift behaviours, and empower communities to act. 

We needed to turn a complex environmental issue into something people could see, feel, and respond to, making invasive species feel like a real and immediate threat, while showing how to help tackle it. 

Launched during Invasive Species Week, our bilingual campaign combined science-led messaging with bold storytelling. A striking visual identity used close-up photography to give invasive species a threatening presence. Creative assets included: 

• Brochures for water users 
• Leaflets and posters for gardeners 
• Explainer films with calls to action like Be Plant Wise and Check, Clean, Dry 
• A bilingual partner toolkit for stakeholder amplification 

Welsh messaging was crafted with cultural nuance and local idioms, especially in rural and coastal areas. Every asset was designed for clarity, balance, and accessibility in both languages. 

The campaign ran for three months across Facebook, Instagram, and Google Search, and exceeded all objectives: 

• +6% national awareness
• 275% above target for campaign page clicks
• 6M+ digital impressions
• 484 pledges to take local action

WaREN II became more than a campaign, it sparked a movement. By blending science, storytelling, and bilingual communication, we helped North Wales Wildlife Trust turn a hidden threat into a clear, compelling call to action.
