It’s Invasive Species Week and throughout the week we’ll be helping to raise awareness about Britain’s invasive mammals. Read our daily blogs.
There are around 200 known invasive non-native plant and animal species in Britain and this number is increasing. A number of these are invasive mammals – and they can have a devastating impact on our native wildlife.
What are Invasive Species?
Invasive Non-Native Species (INNS) are species which have been moved from their place of origin and brought into Britain by humans. They differ from species defined as simply Non-Native in that they have a negative impact on the environment, the economy and health. It is estimated that around 10% of non-native species are INNS, but this number is increasing every year.
In what ways can they be a problem?
Invasive mammals can have negative impacts on the environment, the economy and human health – this could be by predating on native species, damaging crops or causing illness or injury to humans.
What can we do?
During Invasive Species Week we are asking you to help us to build a picture of non-native mammal population size and distribution in Britain. You can do this by downloading the Mammal Mapper app and recording the wild animals you see while out and about or recording historical sightings using our online form.
What should we be looking out for?
Please continue to record native species as usual but this week in particular we would like you to be on special look out for non-native mammals, including those pictured below:
Don’t forget to look out for updates and posts on our website and on social media from Monday 24 May.
