The Emerald Forest

After the Irish fought for and won their independence from the British in 1921, they had a problem. Centuries of exploitation had left the island one of the least forested nations in Europe, with less than 2% tree cover. 

So, they started planting a non-native American tree: fast-growing Sitka spruce capable of rebuilding their timber resources in record time. And it worked. Today, about 17% of the island is forested. But in the rural areas where iconic rolling hills have been replaced by rows and rows of conifers, farmers are not happy.
