Top Ten Burning Issues in Global Sea Turtle Conservation: http://www.seaturtlestatus.org/Main/Why/TopTen.aspx
2) Olive Ridleys in Orissa, India
Current Status: A minimum of 10,000 adults have been killed each year for the past 10 years.
Causes: Trawl fisheries bycatch and coastal development
3) Kemp’s Ridleys throughout their range
(Caribbean, Gulf of Mexico and Atlantic)
Current Status: Kemp’s Ridleys have declined more than 95% in less than 50 years. They live within a limited geographic range and have a small population size, making them especially vulnerable.
Causes: Egg take, bycatch in trawl fisheries
5) Green turtles in the Mediterranean
Current Status: In the major rookeries, located in Turkey, populations have declined by 60-90% in 17 years.
Causes: Coastal development, fisheries bycatch (trawls and gillnets), historical take of meat for export
6) All sea turtles throughout Southeast Asia
Current Status: Hawksbills, green turtles, and olive ridleys have all suffered substantial declines in nesting in this region.
Causes: Direct take of adults and eggs for food and shell trade, fisheries bycatch (trawls, gillnets, pound nets, longlines)
The following are the broad hazards that are presently resulting in declines
and local extinctions of sea turtles, or are in one way or another slowing or
preventing sea turtle recovery.
Fisheries Impacts: Fisheries—especially longlines, gill nets and trawls—impact sea turtles virtually everywhere. Bycatch mortality, habitat destruction and food web changes are the most severe of these impacts.
Coastal Development: Coastal development alters, damages and destroys sea turtle habitats through nesting beach degradation, seafloor dredging, vessel traffic, construction, and alteration of vegetation.
Direct Take: Throughout the world, people kill sea turtles and consume their eggs for food and for products such as oil, leather and shell.
Pollution and Pathogens: Marine pollution—plastics, discarded fishing gear, petroleum by-products, and other debris—directly impact sea turtles through ingestion and entanglement. Light pollution disrupts nesting behavior and hatchling orientation, leading to hatchling mortality. Chemical pollutants can weaken sea turtles’ immune systems, making them susceptible to pathogens.
Global Warming: Global warming may impact natural sex ratios of hatchlings; escalate the frequency of extreme weather events; increase the likelihood of disease outbreaks among sea turtles; and result in loss of nesting beaches, destruction of coral reefs and other alterations critical to sea turtle habitats and basic oceanographic processes.
