11 Current conservation activities Current Regional MPAs (Biosphere Reserve of Fakarava, Scilly and Bellinghausen atolls strict Nature Reserves, Moorea MPA, prohibition on fishing some protected species) 2 programs for MPAs creation (Austral Islands and Marquesas Archipelagos) Examples for specific conservation activities: Protection of natural areas Species conservation Fight against invasive species Integrated coastal areas management Research Awareness raising & environmental education PALIMMA: study on relationship of culture and ocean to create large MPA in Marquesas PUKATAI: creation of 6 educational marine areas managed by local schools Global Ocean Legacy: consultations and evaluation for the creation of large MPAs Partula s programme/picp terrestrial snails BEST project on protection of FP birds: developing management strategy for 32 IBAs Eradication programmes against: Miconia (invasive plants), Fire Ant, Rats RESCUE INTEGRE ( ), 3 areas in French Polynesia (EU funded) Many marine, some terrestrial programs: PACIOCEA (BEST): development of marine spatial planning framework CORAIL (BEST): ES from coral reefs as decision making tools REMMOA: marine species inventory Biocode: genetic barcode species inventory IDEA (Island Digital Ecosystem Avatar): modelling human dependency on biodiversity & ES Different actions by local associations

13 Conservation priorities & investment niches 7 thematic priorities identified by stakeholders during 2 workshops Investment niches (examples): Improved management of current protected areas and regulation (there are some protected areas but poorly managed mainly due to a lack of financial support) Workshops and brainstormings, Papeete, Tahiti, FP Capacity building and training of local civil society, especially on remote islands (very few environmental associations apply for financial aid)

17 Current conservation activities & investments Conservation activities: No regular budgets for the environment but eligible for project funds from the UK for specific initiatives Henderson Island is a World Heritage site since 1998 with a management plan ( ) for raised coral Intention to create a fully protected marine reserve within the Pitcairn Islands EEZ was announced by the UK Government in March 2015 Donors and ongoing programmes and projects: EU, Secretariat of the Pacific Community (SPC), Project INTEGRE, Darwin Initiative, Pitcairn islands
