Seabirds as a tool for a dynamic managment of protected areas and fisheries
Alcyon Programme – Promoting the conservation of seabirds in Cape Verde
Objective: Improve the knowledge and promote the conservation of Cape Verde seabirds.
- Identify the main breeding areas for Cape Verde seabirds.
- Monitoring the phenology and reproductive success of Cape Verde seabirds.
- Identify and control the main threats both in the breeding areas and in the sea.
- Determine the size and population trend of the different species of seabirds.
- Knowing the foraging strategies and identify the most important feeding areas for seabirds during the breeding season.
- Knowing the migration and the areas used outside the reproductive period.
- Determination of the trophic ecology of each species through the analysis of regurgitated and stable isotopes and genetic analysis.
- Training of biologists, protected area technicians and NGOs in research and monitoring techniques.
- Raise awareness of the Cape Verdean population for the conservation of seabirds.
- Preparation of an action and management plan for each seabird species of Cape Verde.
Evaluating the Spanish Marine Protected Areas Network (RAMPE) for the conservation of seabirds in the Spanish Levantine area
Objectives: A global analysis of the spatial overlap between seabirds, their marine habitat, their interactions with fishing vessels, and the fishing activities of each fleet, along the Spanish east coast in general, and very particularly with the current RAMPE.
- Identify the main feeding areas of seabirds in the Spanish Levantine coast and their spatial consistency over the years.
- Characterize the habitat of pelagic birds, and explore the suitability of specific environmental variables as early predictors of their distribution.
- To determine the type and degree of interaction between pelagic birds and the fishing fleet of the Spanish Levantine coast, and to identify the factors that modulate.
- Enhancement of RAMPE and management proposals that improve the suitability of the network as a conservation tool for pelagic birds.
- The results show that the movements of birds can change remarkably throughout the different phases of the period reproductive. This implies that the exposure of birds to different threats.
- The bathymetry and the distance to the breeding colony are the most influential variables when defining the feeding areas of these species.
- The trawl fleet overlap was relevant for most species which requires a high degree of utilization of fishing discards by all these birds. Also, the high degree of overlap between the surface longline fleet and Calonectris borealis and C. diomedea, mainly due to the associated risk of accidental capture.
- The high degree of overlap between these birds, certain fisheries and the current RAMPE has been verified. Specific areas have also been evidenced that are not currently included in the RAMPE.
