Experts from the Norfolk Non-native Species Initiative and the Environment Agency will be at Eaton Vale Activity Centre in Church Lane from 1pm to 7pm to introduce people to the types of alien species invading the county, from killer shrimp (Dikerogammarus villosus) and mink to signal crayfish and fast-growing non-native plants.

Passers-by will be able to use microscopes to take a closer look at some non-native invertebrates.

Will Burchnall, wetland biosecurity officer, said: 'Once these invaders get a foothold they can spread rapidly, killing our native species and harming our recreational facilities by reducing fish populations and restricting navigation.

'We need as many people as possible to come along and learn about them so they have the skills to let us know where these species are and try their best to stop them spreading.'
