The world's slowest mammal in Costa Rica is getting a helping hand from the Sloth Conservation Foundation, created by British zoologist Rebecca Cliffe in 2016. The sloths are at risk as trees are being removed to build houses, tourist cabins, and roads. The foundation is building rope bridges to allow the animals to cross cleared patches of forest safely. Without the bridges the sloths come to the ground to get to another tree and risk being run over by a car or attacked by dogs. If they go over power lines they could be electrocuted. At the start I didn't know if the bridges would work, but thanks to camera traps, we learned that they use them and they are useful, says Cliffe. This is a temporary solution accompanied by tree planting. Once the new vegetation has grown, recreating the habitat, the bridges can be removed. Finding a way for wildlife and economic development to coexist in the region is a crucial challenge. People need to use the land they own and we understand that, Cliffe says. But instead of chasing them, we want to work with the communities as a team."
