Trindade Petrel Pterodroma arminjoniana



Conservation Status

Globally is considered a vulnerable species, because only breeds on two groups of islands in the South Atlantic Ocean, where it is susceptible to human impacts and stochastic events. In Mexico it is no under some category of protection. Introduced cats and pigs may have formerly restricted the breeding population on Trindade to inaccessible cliff sites, and it is also a surface nesting species, so low altitude populations might have been eliminated by feral pigs, cats and humans from the 1700s onwards, except those in small islets surrounding the main island. Some hundreds of goats and/or fire have largely removed forested habitats on the island, but the effect on breeding sites is undetermined. The Brazilian navy is possibly interested in building a small airbase on the island, which could pose threats in its construction and operation. Experimental wind turbines have already been built on the island, with plans to build further wind turbines in the near future. The Martin Vaz Islands have never been inhabited and are unlikely to harbour introduced mammals. Earlier in these sites were carried out navy practices. Since 1967, Brazilian law has afforded protection to all seabirds by forbidding persecution, killing, colony disturbance and the use of bird by-products. The navy eradicated goats from Trindade by 2005 and are restoring forested natural habitats. Pigs and cats were eradicated from the island by 19705. There is an ongoing study on the species's breeding biology. Conservation measures proposed are: Designate the majority of Trindade as a federal reserve1 or national park. Determine the taxonomic status of the unidentified Pterodroma population on Round Island. Conduct an impact assessment before any construction on Trindade.
