FreshWater Watch Citizen Scientists may visit only one site or could monitor several sites a day or a week, have you ever thought that you might be putting your site at risk by transferring Non Native Invasive Species between these sites?
It might be that you pose a risk of transferring seeds from highly invasive plants such as Himalayan Balsam and Giant Hogweed (the sap of this plant can cause blistering or the skin as it reacts with sunlight and you should learn to recognise and avoid it)seeds on clothing or boots, water sampling equipment might transfer water plants like Floating Pennywort or even invasive invertebrates like the "killer Shrimp".
Leeds University have developed a brilliant training resource for Citizen Scientists to learn the risks of Non Native Invasive Species and the simple controls that you can use to prevent you inadvertently moving them from one site to another.
It is free to access via the "Blackboard" platform and you have to create a log in here first of all. Next is a simple survey which really questions you about how you presently monitor sites and any actions you may take to clean equipment?
After this the course proper starts, it is a really fantastic education resource with a mixture of slides and videos with interactive questions to confirm learning at each stage. Finally there is a multi choice exam which when you pass gives you a certificate which you can download and print off.
I cannot recommend this highly enough for everyone involved in Citizen Science site visits of any type.
