To establish the conservation value and document the terrestrial and marine resources of Chumbe Island for the management of the nature reserve, species lists, short reports and studies have been produced on fishes, corals, amphibians and reptiles, birds, bats, butterflies and vascular plants.

As agreed in the management contracts for the Reef and the Forest Sanctuaries, research is, when possible, conducted jointly with the Institute of Marine Sciences of the University of Dar es Salaam and the Departments of Environment, Forestry and Fisheries respectively. Joint research projects currently include: Macroalgae and scleractinian coral recruitment in the Chumbe Reef Sanctuary study (PhD and MSc); A Bioerosion Study (PhD); A study into the fish dispersal factors in the Chumbe MPA (PhD); Community participation and evaluation (PhD). Additionally short-term studies are regularly conducted by visiting researchers from both National and International institutions.

Monitoring surveys conducted reveal that the protection of the reef to the west of Chumbe Island from 1992 by CHICOP has already shown good results. Coral growth and diversity is among the highest in the region, and Chumbe has at least 90% of all the hard coral species that have ever been recorded from Eastern African reefs (Veron, letter 27.3.97). Various reports by IMS state that the diversity and populations are greater on Chumbe in comparison to non-protected areas around Zanzibar (and indeed further afield). Ongoing surveys suggest that some of the fish families are of a greater size and abundance inside Chumbe’s protected area compared to other reefs on the west coast of Zanzibar. For example, groupers and triggerfish seem to be larger than in other sites and sweetlips more abundant.  Nearly 400 species of fish belonging to 50 families have been recorded, including Giant Groupers -Epinephelus lanceolatus- (up to 1m length), which is a rare sighting in shallow reefs (Mildner-Fiebig 1995). The rich fish life has attracted seabirds, such as the rare Roseate Terns -Sterna dougalli-, which have bred successfully on Chumbe. In 1994 around six hundred were ringed by an ornithologist to monitor their movements (Iles 1994). Many lobsters have found a safe haven on Chumbe. On land the rare Robber or Coconut Crab -Birgus latro- is common on Chumbe. The IUCN red list of threatened species describes this species as ‘data deficient’ and it is considered rare elsewhere in the Indian Ocean.

The achievements of CHICOP have been widely acknowledged by international conservation organisations, amongst them the World Conservation Union (IUCN), the World Wide Fund for Nature (WWF), UNESCO-Directorate for Environment and Development in Coastal Regions and Small Islands (CSI) and the United Nations Environment Programme (UNEP).

The Chumbe Reef Sanctuary is now fully registered as a marine protected area by the World Conservation Monitoring Centre (established by UNEP, WWF and IUCN) in Cambridge, United Kingdom. The noted coral taxonomist Prof. J.E.N. Veron from the Australian Institute of Marine Science (AIMS) visited the reserve in February 1997 and established that it has "one of the most spectacular 'coral gardens' to be found anywhere in the world" and that "the Park is exceptionally well managed".
