  1. Planificación sistemática para evaluarla cobertura de AMPs de laplataforma insular de Cuba Hussein Alidina, Jose Gerhartz, Aresenio Areces, Regla Duthit 1st International Marine Protected Areas Congress (IMPAC) Geelong, Australia, October 24-28 2005

  2. Planificación de AP en Cuba 1970s Primeraspropuestas de áreasterrestres 1990s Extensiones a AP terrestres (corales) 2000…. Nuevaspropuestas (delfica) 15% de la plataforma 25% de lasáreas de arrecifescoralinos

  3. Sistema Cubano de AMP

  4. Objetivos • Revisar el sistema existente de AMPs en relación al cumplimiento de un conjuntos de metas explícitas de conservación/ representación • Comparar el sistema existente con el resultante de uno derivado con enfoque sistemático • Determinar vacíos, guiar el desarrollo futuro del sistema en Cuba

  5. Metas del Subsistema de AMPs Criterios para la selecciión de sitios Objetos de Conservación y compilar los datos Establecermetas para los OC - Analisis de vacíos - Seleccion de sitios con Marxan - Comparaciones El proceso GrupoTrabajoTecnico (GTT) • CNAP, IDO, CIP, IES • Apoyotécnico de WWF Serie de talleres • Definircriteriios, OC, metas, revisarresultados…

  6. Objetivos 1: Proteger muestras representativas de la biodiversidad marino costera de Cuba 2: Contribuir a la sustentabilidad de las pesquerías 3: Representar rasgos únicos geográficos y sitios de importancia histórica y cultural

  7. Criterios Objetivo 1: Biodiversidad Representación Eco-regional,Representación y heterogeneidad de hábitat, Gradientes ambientales, Áreas críticas para especies seleccionadas (amenazadas/Endémicas) Objetivo 2: Pesquerìas… Sitios de desove y áreas de cría, para especies de valor comercial Objetivo 3: Historico/Cultural… Rasgos geomorfológicos (cuevas, blue holes), Sitios Culturales o Históricos, Sitios de valor estético

  8. Conservation Features Data/Targets

  9. Lobster Spawning/Juvenile Areas Terrestrial (Shoreline) Habitats Seabed Geology Spawning Aggregation Sites (7 species of Grouper and Snapper) Marine Habitats

  10. Data/Scale appropriate for National Scale Analysis…. GAP/MarXan Analyses - 3347 Planning Units (PU) 5x5km (2500ha) • Data Preparation, Exploratory Runs, Parameter Settings… (BLM, SPF) - Three Analyses • Summary of conservation features within existing MPA System • Unconstrained Selection (Best Solution, Irreplaceable areas) • Selection Considering existing MPA System

  11. In ecoregions with MPAs: Depth Ranges – (10-30m, >150m), Fish Spawning Aggregations, Turtle Nesting Beaches – GENERALLY NOT Adequately Represented In some ecoregions – Marine Habitats, Shoreline habitats are OVER represented…. Results: Representation within the current system

  12. Results: Unconstrained Selection (Best Solution)

  13. Results: Unconstrained Selection (Irreplaceable areas)

  14. Results: Selection Considering existing MPA system

  15. Results Summary The existing system…. • Does not meet more robust targets • Does not contain 45-60% of irreplaceable areas • Would need to increase by 0.25 to 1.7 times more to meet all targets

  16. Take home message… • Without a framework for representation, selection of MPAs remains arbitrary • Important to get systematic planning into the process early • Delaying the implementation systematic planning framework means you will need more area to meet all your targets
