In honor of our #ScientistsInTheField, for this week's #FunFactFriday we're exploring the impact of marine protections, like the designation of current #FoulingSurvey site Cocos Island as an UNESCO World Heritage Site in 1997 and as a National Park of Costa Rica! 
Efforts have been made to preserve the natural ecosystem on and around Cocos. The only permanent residents are park rangers. All visitors (a few tourists and scientists) require permission to visit. No camping, agriculture, fishing, or businesses are allowed on the island.
Despite these extraordinary efforts, the island still faces damage from #invasivespecies. No mammals are native to the island, but deer, wild boar, cats and rats have been introduced. We're there trying to understand how invasive marine species are impacting the ocean ecosystem.
