McClellan C. 2021. Equatorial Guinea 2014: Foraging Green Sea Turtles. Data downloaded from OBIS-SEAMAP (http://seamap.env.duke.edu/dataset/1840) on yyyy-mm-dd and originated from Satellite Tracking and Analysis Tool (STAT; http://www.seaturtle.org/tracking/index.shtml?project_id=1001).


La Región Continental de Guinea Ecuatorial alberga importante hábitat de alimentación para juveniles de tortuga verde (Chelonia mydas) y carey (Eretmochelys imbricata), clasificadas como en peligro y en peligro critico de extinción, respectivamente. Después de un cierto número de años perdidos en alta mar, los juveniles de ambas especies reclutan a aguas costeras, posiblemente a miles de kilómetros de sus playas natales. Zonas rocosas poco profundas adecuados para esta etapa de desarrollo incluyen tres áreas protegidas a lo largo de la costa continental de Guinea Ecuatorial - la Reserva Natural de Río Campo, la Reserva Natural Punta Ilende y la Reserva Científica de Playa Nendji - gestionadas por el Instituto Nacional para el Desarrollo Forestal y la Gestión de las Áreas Protegidas (INDEFOR). Una mejor comprensión del uso del hábitat de las tortugas marinas en esta región es fundamental para informar a todos los esfuerzos de conservación o de mitigación de impactos. En junio de 2014, hemos implementado un estudio de telemetría satelital en una pequeña muestra de tortugas para obtener una primera visión de la utilización del hábitat marino de los juveniles que se encuentran a lo largo de la costa continental de Guinea Ecuatorial.


Equatorial Guinea’s mainland hosts important foraging habitat for juvenile green (Chelonia mydas) and hawksbill turtles (Eretmochelys imbricata), classified as endangered and critically endangered, respectively. After a number of “lost years” in the high seas, juveniles of both species recruit to nearshore waters, potentially thousands of kilometres from their natal beaches. Suitable shallow rocky areas for this developmental stage include three protected areas along Equatorial Guinea’s mainland coastline - the Rio Campo Natural Reserve, Punta Ilende Natural Reserve and Playa Nendji Scientific Reserve - managed by the government’s Institute for Protected Area Management and Forestry Development (INDEFOR). A better understanding of habitat use of sea turtles in this region is fundamental to inform all subsequent conservation or impact mitigation efforts. In June of 2014, we have implemented a study of satellite telemetry in a small sample of turtles to get a first look at the use of the marine habitat of juvenile found along the mainland coast of Guinea Equatorial.
