Kenya plans to undertake an aerial survey to establish the level of conservation efforts needed for marine species found in its territorial waters

This is according to findings released today – June 19, 2023 – from a first-in-30-years survey conducted on marine species along the 600-kilometre Kenyan coastline in March this year.

Consequently, a vigorous law enforcement is needed to reduce harmful human activities threatening already vulnerable marine species along the Kenyan coast, the study undertaken by IFAW reveals.

The aerial survey aimed to establish the level of conservation efforts needed for marine species found in Kenyan territorial waters. It also sought to identify the threats facing these species and their distribution across the coast to help inform appropriate conservation and management measures.

The survey, conducted by a 50-strong survey team comprised of pilots, observers and data capturers, was a collaboration between Wildlife Research Institute (WRTI), Kenya Wildlife Service (KWS), and IFAW (International Fund for Animal Welfare).

The significant species of concern were dugongs, humpback dolphins, whale sharks, and other whale species – all threatened by degradation and habitat loss from harmful human activity. This includes the construction of seaports and increased fisheries activities. Climate change also has a significant effect on the survival of these species.

The survey also revealed that dolphins, listed as critically endangered in East Africa, are Kenya’s most dominant yet most vulnerable and threatened marine megafauna species.

“The existence of marine species and their habitat, though often overlooked, is critical to the survival of the human population,” said James Isiche, Africa Director, IFAW. “The results from the survey are critical in gauging the health and status of marine life and the interventions needed to keep them alive and thriving.”

The report cites harmful human activities as the biggest threats to seagrass beds which dugong and turtles feed. These activities include the clearing of coastal forests for salt pans and construction of shrimp farms, sand mining resulting in massive soil erosion and inshore silt loads and the extraction of mangroves for building material and firewood.

Additionally, accidental capture and their targeted exploitation for food and medicine also threaten the critically endangered dugong. Only two were sighted during the survey compared to groups of up to 500 individuals seen in the 1960s.

Sharks and rays, the report notes, are also declining because of overfishing and the rising global demand for shark products such as fins, meat, skin, cartilage, gill plates, and liver.

The report calls for stringent law enforcement measures to eradicate dangerous fishing gear, such as gill nets that kill dugongs. It also recommends engaging with small-scale fishing communities to implement marine conservation best practices and sustainable fishing techniques.

Kenya’s marine waters host more than 35 species of marine mammals, five species of marine turtles – all listed as endangered or critically endangered – and 105 species of bony fishes, including sharks and rays.
