Sal Rei Bay (on the Island of Boavista, Republic of Cape Verde), including the waters immediately adjacent to the harbour, comprises the single most important breeding location known to a small and threatened population of humpback whales (Berubé et at. 2013; Ryan et al. 2013). Plans to conduct underwater blasting at Sal Rei Harbour from April until August 2014 will, in our professional opinions, likely result in the injury (Todd et al. 1966) or potential death (Ketten et al. 1993) of humpback whales.
This is one of the smallest populations of humpback whales in the world (Berubé et al. 2013), and even a small mortality event could compromise the viability of this already threatened population. Measures to protect this species are required by a range of international agreements and conventions to which Cape Verde is signatory: the Convention on Biological Diversity (ratified on 29.03.1995), the Convention on the Conservation of Migratory Species of Wild Animals (ratified on 01.05.2006).
In addition to the serious conservation issues at stake for this threatened population of whales, the local whale-watching business and tourism will suffer greatly if these animals are displaced from the region.
We urge you to take immediate action to ensure that underwater blasting does not take place during the critical breeding and nursing period of these whales (February-June). In addition, the Cape Verdes are a major nesting site for loggerhead turtles (Caretta caretta), which come to the islands between May and August. These endangered animals would also be harmed by the explosions in the harbour.
We therefore ask that these activities, the use of explosives in Sal Rei Harbour, be postponed until October.
