Biodiversity Misali Island hosts a variety of terrestrial and marine species. The island is the only last home for the
Aloe pembana, a native species that was once widespread through the islands. The ecosystem supports endangered terrestrial species such as the
Pemba flying fox,
vervet monkeys, and
coconut crabs. The island's reefs are vital habitats and contain more than 300 fish species and 40 coral species.
Conservation program Originally established in 1998 as the Misali Island Marine Conservation Area, later the island was incorporated into the legally protected Pemba Channel Conservation Area (PECCA) under Zanzibari law. The approach to marine protection includes multiple efforts. Daily ranger patrols monitor the coral reefs, and community members help enforce bans on destructive practices such as dynamite fishing and spear guns. A visitor fee of $10 per day contributes directly to conservation programs. The program also implements habitat management strategies for coral reef restoration, mangrove replanting near villages, and the designated no-fishing zones that now cover a third of the reef area. The initiative's success is supported by strong engagement with the community. Islamic environmental education helps align conservation goals with local beliefs. Training in alternative livelihoods including beekeeping and ecotourism reduces pressure on marine resources. Local conservation committees are equipped with reporting systems to help ensure grassroots accountability and sustained participation in the program's goals and outcomes.
Habitat restoration Since 2000, the Misali conservation program has included mangrove replanting initiatives along village shores. These efforts, funded by visitor fees, serve dual purposes: creating fish nursery habitats to support fisheries and preventing coastal erosion. Local women's groups lead the planting efforts, with more than 10,000 mangroves established by 2013.
Enforcement and patrol system A community-run patrol system enforces fishing rules, using licensed rangers and village committees to report violations. PBS documented how confiscated illegal gear includes spear guns and fine-mesh nets, with fishermen receiving warnings rather than fines for first offenses. == Tourism ==
