Background information Spatial extent of activities Marine turtle Species/distribution Threats and conservation status 2.) Research and Monitoring/results General research activities Tagging programs Genetic studies Monitoring methods Gaps 3). Conservation and management/lessons and experiences Participatory approaches Nest protection programs Fisheries Collaboration strategies/networks established National policy and legislative mechanisms BACKGROUND INFORMATION KESCOM-established in 1993 and has 200 members constituted by students, individuals, corporate entities, NGOs and Government Institutions Respond to increased reports of mortalities and poaching and trade in marine turtle products Initiative to supplement government s commitment to addressing global concerns for marine turtle population decline Initial activities limited to Mombasa Currently has established 10 community based conservation groups over 50% of potential nesting grounds and adjacent waters Spatial extent of marine turtle conservation initiatives in Kenya and nesting sites Activity TCG Kiunga TAFMEN Robinson Kilifi Baobab Bodo Sample TCGs Activities Reports on turtle activity Other marine programs Habitat rehabilitation Education and Awareness Income generating activity

Aerial survey of marine mammals and turtles. # turtles sighted 107 Species sighted Dc, Cm, Cc, Ei, # nests 37 # false crawls 25 Recent studies Mueni and Mwangi, 2000. A survey on the use of TEDs in trawlers along the Kenyan coast By-catch 70% of total catch Reported over 35 turtles caught in the trawlers within a sampling period spread over three months TEDs which are currently in use on Kenyan Trawlers are not quite effective in excluding turtles On board Observers have reported breakages, reduced target catch

Trawling-issue of national interest Resource use conflicts-economic benefits/value Environmental degradation By-catch- 70-80% Commercially important juvenile fish and endangered species Task force established- Mandate address research needs, socio-economics and make appropriate recommendations to stakeholders KESCOM is represented in the task force Recent studies Okemwa, et. al. 2004. The Status and Conservation of Sea Turtles in Kenya (MTN 105). Background information on conservation of sea turtles in Kenya Analysis of data collected by TCGs, Hoteliers and Individuals from 1997-2000 Describes the conservation measures undertaken to mitigate threats Major findings from Okemwa et. al. 2004 Green turtle nests constitute 91% of nests sighted Clutch sizes range from 40-244 eggs for green, 102-210 for hawksbill and 84-104 for olive ridleys Incubation period is between 55-74days for greens, 54-69 days for hawksbills and 52-64days for olives An upsurge in mortalities reported in 2000 and 2001(54%, greens) -increased surveillance Public awareness, capacity building and general empowerment of the fishermen and local people, a priority Recent studies Nzuki, et. al. 2004. Enhancing Community Participation in the Conservation of Sea Turtles in Kenya (BP Conservation program).

GAPS A. ) Inadequate data and information on population status, structure B.) National data an under estimate due to; 1.) Some nesting areas not covered 2.) Limited effort allocated to patrols and monitoring 3.) Limited resources C.) Inadequate data on migrations and remigrations intervals D.) Inadequate socio-economic data CONSERVATION AND MANAGEMENT Participatory approaches KESCOM is using participatory approaches to promote stakeholder participation in conservation of turtles. Four main stakeholders; local people, government, private sector, NGOs A national PRA process has been initiated aimed at assessing habitat status and developing time lines for resource use-marine turtles being used as flagship Marine resource conservation problems being assessed and ranked socio-economic status of local people
Nesting habitat survey training for TAFMEN Awareness in a local hotel Community Action ADF addresses local fishermen in Kipini Mangrove replanting-bodo Morphometrics training Community education Education and awareness Identified target groups-communities, schools, Identified needs, developed objectives Collaborate with partners -Wildlife Clubs of Kenya to implement education programs Information disseminated through periodicals Kasa News(KESCOM news quarterly) and wildlife club magazines Targeted awareness raised through regular campaigns and follow-up activities targeting local fishers and other marine resource users EST PROTECTION PROGRAMS Some TCGs have a cash incentive (average of US$10) scheme to encourage in situ protection of nests by local people Nest adoption programs in some areas (eco-tourism) Translocate to secure areas Natural predation -caging and rotation of translocation areas Kiunga Baobab Releases by fishermen (2000-2003) Year Site 2000 64-2001 274 Totals 64 274 296 GRAND TOTAL 1,212-2002 296-2003 544 31 34 609 Collaboration/ Networks/Linkages Database of experts in WIO region developed Local networks developed with private, government and NGOs sector Collaborating with national institutions-fisheries, KWS, KMFRI, CDA, NMK Some collaborating institutions i.e. KWS and FD charged with implementation of legislation for sea turtle conservation-wildlife and Fisheries Act Cap. 376 and 378 respectively. KWS has developed management guidelines for MPAs in Kenya Networks with other sea turtle conservation projects - regional range states Linkages developed with regional marine programs- WCS, WIOMSA, IUCN-EARO and WWF-EAME National policy and legislation Kenya is a signatory to major international/regional instruments relating to marine turtles; e.g. CITES, CMS, IOSEA_MOU Has national legislation; Cap 378 of the Fisheries Act (specific) and CAP 376 of the Wildlife Conservation and Management Act (regarded as trophy). Weaknesses of current legislation 1.) Implementation 2.) Does not address the issue of habitats 3.) Jurisdictional overlaps 4.) Penalties -Not effective deterrent 2years/US$ 250 -No clear penalties for specific infringements
