SAMOTHRAKI, Greece (AP) — With oak and chestnut forests, waterfalls and rugged coastline, Samothraki has a wild beauty and a remoteness that sets it apart from other Greek islands.

There are no package holidays here or even a reliable ferry service to the mainland. Island authorities hope to achieve UNESCO Biosphere Reserve status. Yet still, the natural environment is under threat from an insatiable assailant.

Semi-wild goats outnumber human inhabitants 15-fold, and they are munching stretches of Samothraki into a moonscape. After decades of trying to find a solution, experts and locals are working together to find a 21st-century way to save the island's ecology and economy.
