Serbia: Endemic spruce at risk of extinction due to heat

As temperatures around the world rise, the rare Pancic spruce, a species of coniferous tree, is at risk of extinction. 

Although sometimes planted elsewhere, this tree only grows naturally in Serbia and parts of Bosnia and Herzegovina and is currently found in an area measuring about 200 square kilometers [77 square miles]. Although it has thrived in both countries for an estimated 22 million years, it is struggling to cope with drought and shrinking habitats. 

Scientists are trying to save the tree, which is considered a national treasure in both countries, using genetics, dedicated nurseries and even, potentially, planting in Scandinavia.
