Protect habitat: Sea turtles
A replicated, randomized, site comparison study in 2009–2010 on an offshore coral reef atoll with two marine protected areas near Belize (Scales et al. 2011) found that hawksbill turtle Eretmochelys imbricata abundance was greater inside than outside protected areas. Hawksbill turtle abundance was greater inside protected areas (2–3 turtle sightings/hour) than outside protected areas (1 turtle sightings/hour). Hawksbill turtles were surveyed in the vicinity of a coral reef atoll (45 km long and 10 km wide) that contained six small cays and two no-take protected areas. Turtles were monitored on 49 randomly selected transects (1 km long) carried out over 30 days in April–May 2010 by three swimmers (1–20 m depths). In addition, 26 turtles were captured in April–May 2009 and in May 2010. Captured turtles were weighed and measured and a subset (10 individuals in 2009 and 9 individuals in 2010) were radio tracked every 24 hours for 6–25 days. It is unclear whether the captured turtles were included in the abundance estimates.
