Tracking the American bullfrog spread 🐸

How do you stop an invader that leaps 1.8m? #GuardIAS is using eDNA to track its spread into the Netherlands and identify high-density breeding ponds for removal.

Building Europe's Early Alert System for Invasive Species | GuardIAS Tech YouTube video by GuardIAS-EU

[Interview] How do you track 10,000+ species at once? 🛰️👾

#GuardIAS is building a system that instantly notifies managers of new invasions across Europe.

Data speed = faster protection.

A single marbled crayfish can start a population alone. 🦞

In the Netherlands, we're using eDNA to protect ponds from this rapid invader. At this stage, control is still possible!
