People in Jersey are being urged to protect red squirrels, over concerns they could become extinct within the next decade in the UK.
A major study has categorised them on the 'red list of threatened species'.
The review led by the Mammal Society and commissioned by government agency Natural England, examined 1.5 million records of mammals across Britain including data from “citizen science” reports and local wildlife groups.
It also found wildcats and grey long-eared bats among the species which face severe threats to their survival.
The exact population of red squirrels in Jersey is unknown.
