    Red squirrels (松鼠) , a kind of animal once lost from their native woodlands, have been returned to the north-west Highlands, early results of a reintroduction (重新引进) project show.

The new population has naturally increased since they were reintroduced to north-west Scotland last year. The animal had disappeared as a result of the reduction of forests, as well as illness and competition from the introduced non-native grey squirrel. However, Trees for Life—the organization behind the project—is hopeful that red squirrels will continue to add to their 138,000 number and continue their increase.

“Early results shows that this could be a real wildlife success story. The new squirrel populations are not only living in their new homes, they are also starting to spread out into new areas, with squirrels being sighted as far as 15km away, “said Becky Priestley, Trees for Life’s wildlife officer.

The first relocation began in the spring of 2016, through to this year, when the first 33 squirrels from Inverness-shire and Moray were set free at Shieldaig in Wester Ross. Another 22 were set free at the Coulin estate, next to Beinn Eighe, plus 30 at Plockton, which is partly owned by the National Trust for Scotland.

The red squirrel, found throughout Eurasia, has experienced a great population reduction in recent years. In 2007, just 25,000 could be found throughout the UK after a one-time high of 3.5 million. This is often because of the fact that their grey cousins have a larger appetite (食欲) and eat most of the food in the forest. Reds are also more likely to be influenced by viruses (病毒) than greys, dying up to 25 times quicker.

Grey squirrels first came to England from North America in 1876 as a decorative species. However, it was not until 1930 that the damage they did was realized, when it was almost too late for the reds.

Now, though, red squirrels appear to naturally take over their land again. During 2016, they spread beyond Shieldaig, with one sighting eight miles away beyond Loch Torridon. One was seen recently near Nostie, about five miles from the release site, and there have been sightings further.
