Population number According to the Sea Turtle Conservancy resource the total population size of nesting Hawksbill sea turtles is around 20,, individuals. Ecological niche Hawksbills help with maintaining the health of the coral reefs by removing prey such as sponges off the reef's surface, thus enabling better feeding access for reef fish.

Two recovery plans have been developed to recover and protect hawksbill turtle populations that are found in the U.
Each is focused on the unique needs of hawksbill turtles in the various regions. The highly migratory behavior of sea turtles makes them shared resources among many nations, so conservation efforts for sea turtle populations must extend beyond national boundaries.
This necessitates international collaboration and coordination. Learn more about international conservation efforts below. NOAA Fisheries is working to minimize effects from human activities that are detrimental to the recovery of hawksbill turtles in the United States and internationally. Together with our partners, we undertake numerous activities to support the goals of the hawksbill turtle recovery plans, with the ultimate goal of species recovery. Efforts to conserve hawksbill turtles include:.
Those areas may be designated as critical habitat through a rulemaking process. A critical habitat designation does not set up a marine preserve or refuge. Rather, federal agencies that undertake, fund, or permit activities that may affect designated critical habitat areas are required to consult with NOAA Fisheries to ensure that their actions do not adversely modify or destroy these designated critical habitats.
Coral reefs, like those found in the waters surrounding Mona and Monito Islands, are widely recognized as the primary foraging habitat of hawksbill turtles in the U. There is no critical habitat designated for hawkbills in the Pacific.
View the Hawksbill sea turtle critical habitat map. NOAA Fisheries is working to reduce the bycatch of sea turtles in commercial and artisanal fisheries. Our efforts are focused on documenting bycatch, understanding how, why, and where sea turtles are bycaught, and how to reduce that bycatch. These modifications are required in certain U.
Measures include:. TEDs are required in the shrimp otter trawl fishery and, in early , in larger vessels participating in skimmer trawl fishery. Since , the U. The import ban does not apply to nations that have adopted sea turtle protection programs comparable to that of the United States i. The U. Department of State is the principal implementing agency of this law while NOAA Fisheries serves as technical advisor and provides extensive TED training throughout the world.
We are also involved in cooperative gear research projects, implementation of changes to gear and fishing practices, and safe handling protocols designed to reduce sea turtle bycatch and mortality in the Gulf of Mexico and Atlantic pelagic longline fisheries, the American Samoa and Hawaii-based longline fisheries , the Atlantic sea scallop dredge fishery, and non-shrimp trawl fisheries in the Atlantic and Gulf of Mexico.
Bycatch in fishing gear is the primary human-caused source of sea turtle injury and mortality in U. The most effective way to learn about bycatch is to place observers aboard fishing vessels.
Observers collect important information that allows us to understand the amount and extent of bycatch, how turtles interact with the gear, and how bycatch reduction measures are working. NOAA Fisheries determines which fisheries are required to carry observers, if requested to do so, through an annual determination.
Observers may also be placed on fishing vessels through our authorities under the Magnuson-Stevens Act. A stranded sea turtle is one that is found on land or in the water and is either dead or is alive but unable to undergo normal activities and behaviors due to an injury, illness, or other problem. Most strandings are of individual turtles, and thousands are documented annually along the coasts of the United States and its territories.
Organized networks of trained stranding responders are authorized to recover dead turtles or assist live turtles and document important information about the causes of strandings. These networks include federal, state, and private organizations. The actions taken by stranding network participants improve the survival of sick, injured, and entangled turtles while also helping scientists and managers expand their knowledge about threats to sea turtles and causes of mortality.
Because sea turtles spend most of their life at sea and out of sight, information learned from strandings are an important way for us to identify and monitor problems that threaten sea turtle populations. Within the United States and its territories, there are three regional networks that serve to document and rescue stranded and entangled sea turtles:. The actions taken by stranding network participants improve the survivability of sick, injured, and entangled turtles while also helping scientists and managers to expand their knowledge about diseases and other threats that affect sea turtles in the marine environment and on land.
The conservation and recovery of sea turtles requires international cooperation and agreements to ensure the survival of these highly migratory animals. We work closely with partners in many countries across the globe to promote sea turtle conservation and recovery. Two international agreements specifically focused on sea turtle conservation are:. The hawksbill sea turtle was first listed under the Endangered Species Act in The ESA 5-year review concluded that the species continues to meet the definition of an endangered species, based on the best available information.
In , we finalized regulations to require turtle excluder devices TEDs in shrimp trawl fisheries to reduce sea turtle bycatch.
Since then, we have updated these regulations as new information became available and TEDs were modified to improve their turtle exclusion rates. We have implemented other measures to reduce sea turtle bycatch through regulations and permits under both the ESA and Magnuson-Stevens Act.
These requirements include the use of large circle hooks in longline fisheries, time and area closures for gillnets, and modifications to pound net leaders. See all regulations to protect sea turtles.
NOAA Fisheries conducts research on the biology, behavior, and ecology of the hawksbill sea turtle. The results of this research are used to inform management decisions and enhance recovery efforts for the species.
This information can help NOAA Fisheries evaluate the effectiveness of conservation and recovery measures, and can help guide actions to enhance recovery. To estimate population abundance, researchers conduct aerial and vessel-based surveys of selected areas and capture and mark turtles in the water and on beaches. We also incorporate data collected on nesting beaches via stranding networks and from fisheries observer programs. Other information that informs sea turtle population assessments includes population structure genetic analyses , age to maturity, survivorship of the various life stages e.
Satellite telemetry allows researchers to track sea turtles as they migrate between and within foraging and nesting areas. The data help us understand migration patterns, identify feeding areas, and identify where turtles overlap with their primary threats e. We observe fisheries to understand the level of sea turtle bycatch and the ways in which turtles interact with fishing gear. Learn more about our fishing gear research.
