Mangrove biologistDr. Candy Feller has spent the last 35 years among the mangrove roots researching the relationship between mangrove growth, nutrients, and the animals that rely on the forests. In fact, the various species of mangroves arent necessarily closely related to one another, but they do share the unique capability of growing within reach of the tides in salty soil. The Mangrove Alliance is a group spearheaded by the German Federal Ministry for Economic Cooperation and Development, the World Wide Fund (WWF) and the International Union for the Observation of Nature (IUCN) that aims to increase global mangrove forests by 20 percent by 2030.
