LAURA BARRON-LOPEZ: Finally tonight, we leave you with scenes from some of the world's newest protected sites courtesy of UNESCO's World Heritage Committee.

LAURA BARRON-LOPEZ (voice-over): This vast landscape in the north of Scotland is helping fight climate change by storing more than 400 million tons of carbon in its dense peak.

MILLY REVILL HAYWARD, Royal Society for the Protection of Birds: It's a brilliant, brilliant example of what a blanket bulb can look like, and the type of species that you can find here.

Flow country represents 5 percent of all blanket bulb research in the world.

LAURA BARRON-LOPEZ (voice-over): Now, it's been designated by UNESCO as one of the best examples of a crucial, yet threatened ecosystem that's helping the planet keep breathing.

Within its 1,500 square miles is a diverse range of wildlife and plants, including mosses that store large quantities of water in their cells.

Another site in China is a stopover for millions of migrating water birds on the Yellow Sea.

WU WEI, Chonming Dongtan National Nature Reserve (through translator): On our right hand side is the boundary of our protected area.

Among the breeding bird species recorded here are the black winged stilt, little ringed plover and the black headed gull.

LAURA BARRON-LOPEZ (voice-over): The site supports crucial habitats for birds migrating between the Arctic and Southeast Asia and Australasia.
