A replicated, site comparison study in 1996 and 2003–2004 in 12 marine areas in coastal Kenya and Tanzania (McClanahan et al. 2006) found that areas with community-based coral reef management with a history of destructive fishing had similar coral cover and diversity compared to Marine Protected Areas with no fishing. Coral cover was similar in community-managed sites (1996, before bleaching: 24 cm/m; 2004, post-bleaching: 28 cm/m) compared to protected sites (1996, before bleaching: cover 22 cm/m; 2004, post-bleaching: 32 cm/m). The diversity of hard coral species was also similar between community-managed sites (1996, before bleaching: 12 coral species/90 m transect; 2004, post-bleaching: 13) compared to protected sites (1996, before bleaching: 12; 2004, post-bleaching: 13). Community enforcement reduced dynamite fishing from 180 blasts/month in 1995 to <5/month in 2003. Coral reef sites of similar aspects (four small collaborative managed reefs in the Mtang’ata Community Managed Area and three separate sites in Marine Protected Areas with no fishing) were compared and included Malindi, Watamu and Mombasa Marine National Parks. The Mtang’ata collaborative managed area reefs were included in 1994 as recognition of the degradation due to dynamite fishing and illegal mangrove cutting and to enhance the well-being of the coastal communities by improving management. Communities were surveyed using nine 10-m line transects/site with benthic biota >3 cm in length classified into nine gross categories; hard coral were further identified to genus.
Study and other actions testedA replicated, site comparison study in 2011 at six sites off the coast of Kenya (Humphries et al. 2014) found that areas with community-based management had similar coral cover compared to government-managed no-take zones and fished areas. Coral cover did not vary based on management type and was 26 and 46% in community closures, 20 and 27% in Government closures and 7 and 35% in fished areas. Two community-managed areas were closed to fishing in 2005 and 2010. Two government closures were protected since 1968 and 1991. Two fished areas were fished intensively with a range of gear (including spearguns, nets, traps). Coral cover was surveyed using randomly placed 10 m transects (nine transects/site).
