IAS-ESS was conceived to provide a central repository for Invasive Alien Species monitoring. The main benefit is that it is generalised to allow any expert to track their area of concern, whilst allowing the data gathered to be specific enough to that particular organism.

To get started, register. You can then add a species for tracking, set up a 'watched' management area, or just submit sightings (though you can do that without registering, too). If the species you wish to track is already listed, you may wish to contact the expert who is currently monitoring it, and join forces!

The Invasives Research Group is involved in active development of control and management tools and techniques. IAS-ESS is one such tool, freely available to use by experts and citizen scientists.
