Guest writer, Dr Jenna Ross, from Crop Health and Protection (CHAP), joins us for the second of her two-part special series (read part 1) on the outputs of her prestigious Nuffield Farming Scholarship. Jenna spent 26 weeks travelling the world studying all aspects of slug invasions and slug control, and in this article discuss the impact of slug invasions on UK biosecurity.
Guest writer, Dr Jenna Ross, from Crop Health and Protection (CHAP), joins us for a two-part special series (read part 2) on the outputs of her prestigious Nuffield Farming Scholarship, where she spent 26 weeks travelling the world studying all aspects of slug invasions and methods of control. In Part 1, Jenna discusses the current slug fauna of the UK and potential slug invasions.
The slug fauna of the UK is constantly evolving. To date, there are an estimated 42 slug species in the UK, with another newly introduced milacid species identified in 2018. However, what is particularly interesting, is that of the species present in the UK, only 18 are native, with the rest being introduced. This means that over 50% of the UK’s slug fauna are exotic. So why are slugs so successful at invading new habitats? There are many reasons for this, including their high reproductive rates, environmental tolerance, flexible behaviour, ability to thrive in association with humans (synanthropic) and the fact they are free from their natural predators and parasites when entering new unoccupied ecological niches.
