To restore degraded coral reefs and create additional ‘artificial’ coral reefs, corals are planted in the area of interest. But where do these corals come from?

 

A coral is a colony of many little identical coral polyps that work together to form a great underwater structure. Due to storms, animals or humans, branches of these structures sometimes break and end up on the sandy bottom. The polyps of these branches are still alive, but they cannot survive if they are covered by sand. REEFolution uses these coral fragments and gives them a second chance by placing them in ‘so called’ coral nurseries.  Nurseries are structures that places the corals in better nutritional and light conditions and raises them from the sandy bottom. Although there are many designs that might be used for coral nurseries, a quick study done end of 2015 revealed that the coral nursery tree is most effective and easy to construct.

The coral tree nursery has already successfully been used in other coral restoration projects done in the Caribbean (Coral Restoration Foundation). The nursery tree is a structure that is formed using PVC piping. Small PVC pipes are attached horizontally to a bigger vertical PVC trunk, forming branches of the ‘tree’. Coral fragments are attached to these branches by thin ropes. The corals in the ropes have the opportunity to grow and once they are big enough, these corals are used for restoration or creation of new reefs.

The first coral restoration trees have been placed at the first REEFolution location in Kenya, off the coast of Shimoni. This place is situated near the Kisite-Mpunguti National Marine Park. The grown fragments from the nurseries can therefore easily be used to restore degraded parts in and near the park.
