Odlehlé útočiště mořských ptáků objevené v severním Atlantiku se brzy stane chráněnou mořskou oblastí

The name of the area is NACES – the North Atlantic Current and Evlanov Seamount - Marine Protected Area.
This major seabird hotspot has been discovered through a huge collaborative effort led by BirdLife International. Using tracking, phenology, and population data, BirdLife mapped the abundance and diversity of 21 seabird species. This revealed a major hotspot used annually by 2.9–5 million seabirds from more than 56 colonies across the North and South Atlantic, making this one of the most important concentrations of migratory seabirds in the Atlantic and the first discovery of seabird concentrations of this magnitude ever documented on the high seas.
This is the first time that a Marine Protected Area in the high seas will be designated based on tracking data.
Protection of the NACES Marine Protected Area is needed to ensure current and future uses do not compromise the biodiversity and ecosystem processes supported by the site. By turning this site into a Marine Protected Area, it can be protected by being disrupted by human activities at sea.
The seafloor within NACES comprises a wide range of biotopes and the site is characterised by a complex array of bathymetric features, including abyssal plains, ridges, canyons, and seamounts – including the Evlanov seamount from which the site gets its name.
BirdLife is calling for the full protection of this area, from seafloor to sea-surface, to safeguard the biodiversity and ecosystem processes that the site supports. A management plan detailing the conservation measures for the area must be developed following its designation, in order to implement and enforce appropriate conservation measures.
Globally, seabirds have declined by 70% in the last 50 years and are currently the most threatened group of birds in the world. Five globally threatened species depend on this area for their survival: the endangered Bermuda Petrel (Pterodroma cahow), and Zino's Petrel (Pterodroma madeira), as well as the Desertas Petrel (Pterodroma deserta), Black-legged Kittiwake (Rissa tridactyla), and the Atlantic Puffin (Fratercula arctica) which are classed as Vulnerable and have rapidly declining populations.
The proposal for the NACES Marine Protected Area started in 2016, with a workshop led by BirdLife International for seabird experts. This led to a huge effort to gather all available seabird tracking data for the North Atlantic and created a robust dataset for the analysis that ultimately led to the identification of the NACES Marine Protected Area. The identified seabird hotspot was then proposed to OSPAR1 and since that time it has undergone scrutiny and revisions for the last four years, before finally making over the finish line.
