“…Inter-nesting sites overlapped with areas of shrimp trawling and oil and gas extraction activities, and our findings can be used to help develop strategies to protect Kemp’s ridley turtles from these activities and other threats. Satellite tracking data have been used to identify important inter-nesting, foraging, and migratory habitat of other sea turtle species, assess threats to sea turtles within those habitats, and aid with spatial planning for marine conservation in the USA [ 51 , 78 , 80 , 81 ] and other countries [ 30 , 34 , 82 – 88 ].…”

“…This information can then aid in the delineation of protected areas and development of conservation strategies. For other sea turtle species, satellite tracking data have been used to identify inter-nesting movements and habitat, assess threats within those habitats, and assist with marine spatial planning for conservation in the USA and other countries [ 26 – 34 ]. Here we characterize inter-nesting habitat in the GOM for Kemp’s ridleys tracked by satellite telemetry after nesting at or near PAIS, RN, and VC.…”

Inter-nesting movements and habitat-use of adult female Kemp’s ridley turtles in the Gulf of Mexico

Species vulnerability is increased when individuals congregate in restricted areas for breeding; yet, breeding habitats are not well defined for many marine species. Identification and quantification of these breeding habitats are essential to effective conservation. Satellite telemetry and switching state-space modeling (SSM) were used to define inter-nesting habitat of endangered Kemp’s ridley turtles (Lepidochelys kempii) in the Gulf of Mexico. Turtles were outfitted with satellite transmitters after nesting at Padre Island National Seashore, Texas, USA, from 1998 through 2013 (n = 60); Rancho Nuevo, Tamaulipas, Mexico, during 2010 and 2011 (n = 11); and Tecolutla, Veracruz, Mexico, during 2012 and 2013 (n = 11). These sites span the range of nearly all nesting by this species. Inter-nesting habitat lies in a narrow band of nearshore western Gulf of Mexico waters in the USA and Mexico, with mean water depth of 14 to 19 m within a mean distance to shore of 6 to 11 km as estimated by 50% kernel density estimate, α-Hull, and minimum convex polygon methodologies. Turtles tracked during the inter-nesting period moved, on average, 17.5 km/day and a mean total distance of 398 km. Mean home ranges occupied were 725 to 2948 km2. Our results indicate that these nearshore western Gulf waters represent critical inter-nesting habitat for this species, where threats such as shrimp trawling and oil and gas platforms also occur. Up to half of all adult female Kemp’s ridleys occupy this habitat for weeks to months during each nesting season. Because inter-nesting habitat for this species is concentrated in nearshore waters of the western Gulf of Mexico in both Mexico and the USA, international collaboration is needed to protect this essential habitat and the turtles occurring within it.

8As species of conservation concern, sea turtles have historically been difficult to study because of their 9 elusive nature and extensive ranges, but improvements in telemetry have facilitated insights into life 10 histories and behaviours which can potentially inform conservation policies. To date, there have been few 11 assessments of the impact of satellite tracking data on species conservation, and it is difficult to clearly 12 gauge whether the dividends justify the costs. Through an extensive review of the literature (369 papers, 131982-2014) and a questionnaire-based survey of 171 sea turtle tracking researchers, we evaluate the 14 conservation dividends gained thus far from tracking and highlight conservation successes. We discuss who 15 is tracking and where, where biases in effort exist, and evaluate the impact of tracking data on 16 conservation. Conservation issues are increasingly being considered. Where research recommends policy 17 change, the quality of advice varies and the level of uptake is still uncertain, with few clearly described 18 examples of tracking-data actually influencing policy. The means to increase the conservation impact are 19 discussed, including: disseminating findings more widely; communicating and collaborating with colleagues 20 and stakeholders for more effective data sharing; community liaison, and endeavouring to close the gaps 21 between researchers and conservation practitioners. 22
