Tourism officials with northwest England's Lake District National Park said Japanese tourists are being singled out by the scheme, set to begin next week, because they travel to the "Peter Rabbit" author's cabin in the thousands, The Times of London reported Thursday. Advertisement Keira Holt, a marketing executive with Nurture Lakeland, said the donation is voluntary and may soon be spread to other foreign visitors. "Ecotourism is huge in Japan," she said. "We are incredibly appreciative that their concern for the environment extends to our own country." "The money will go towards anything to do with conservation, restoring worn footpaths and promoting biodiversity such as projects to protect species like the red squirrel," she said.
