Los Roques de Salmor and the surrounding tidal reefs form the strict nature reserve off northern El Hierro. Its management plan highlights the rock landscape and the seabirds that nest there. [1]
Protection of Salmor began in 1987 within the Gorreta y Salmor natural area. In 1994, the rocks were reclassified as a strict nature reserve. After El Hierro became a Biosphere Reserve in 2000, this site formed part of one of its core zones. [1]
On 13 July 2022, two researchers landed on Roque Grande and surveyed it for two hours. They found seventeen active Bulwer’s petrel nesting cavities, all with incubating adults, as well as breeding European storm petrels. The team considered that limited survey time and the timing of the visit could leave some nests unrecorded, and highlighted the rock’s importance as a breeding site. [2]
