HAWKSBILL-TURTLE
AN ENDANGERED SPECIES
Scientific Name: -Eretmochelys imbricata
Hawksbills help maintain the health ofcora ree"#. As they remove prey such as sponges from the
reef's surface, they provide better access for reef fish to feed. They also have cultural significance
and tourism value. For example, for local residents in the Coral Triangle, the flow of visitors who come
to admire turtles is a vital source of income.

CAUSES OF ENDANGERMENT
Destructive fishing practices: These include cyanide fishing, dynamite fishing, and
bottom trawling. Bottom-trawling is one of the greatest threats to cold-water coral reefs.
Overfishing: This affects the ecological balance of coral reef communities, warping the
food chain and causing effects far beyond the directly overfished population.
Careless tourism: Careless boating, diving, snorkeling, and fishing happens around the
world, with people touching reefs, stirring up sediment, collecting coral, and dropping
anchors on reefs. Some tourist resorts and infrastructure have been built directly on top
of reefs, and some resorts empty their sewage or other wastes directly into water
surrounding coral reefs.
Pollution: Urban and industrial waste, sewage, agrochemicals, and oil pollution are
poisoning reefs. These toxins are dumped directly into the ocean or carried by river
systems from sources upstream. Some pollutants, such as sewage and runoff from
farming, increase the level of nitrogen in seawater, causing an overgrowth of algae,
which 'smothers' reefs by cutting off their sunlight.
Sedimentation: Erosion caused by construction (both along coasts and inland), mining,
logging, and farming is leading to increased sediment in rivers. This ends up in the
ocean, where it can 'smother' corals by depriving them of the light needed to survive.
The destruction ofmangrove forests, which normally trap large amounts of sediment, is
exacerbating the problem.
Coral mining: Live coral is removed from reefs for use as bricks, road-fill, or cement for
new buildings. Corals are also sold as souvenirs to tourists and to exporters who don'tknow or don't care about the longer term damage done, and harvested for thelive rock
trade.
Climate change: Corals cannot survive if the water temperature is too high. Global
warming has already led to increased levels of coral bleaching, and this is predicted to
increase in frequency and severity in the coming decades. Such bleaching events may
be the final nail in the coffin for already stressed coral reefs and reef ecosystems.

Platanthera praeclara
The Endangered Species Coalition
estimates that there are only 172
populations of this plant, with
merely four with more than 1,000
plants. This is a wetland plant that
grows in “prairie potholes”, indents
left by glaciers in the recent ice
age, 20,000 years ago.
CAUSES OF ENDANGERMENT Fires, overgrazing, Global warming
and habitat fragmentation also have
contributed to the decline of the species.

populate many isolated oceanic islands. !n
addition, these birds often prefer to run
rather than fly. "any #inds of rails have
therefore given up on flying altogether.
Flightlessness can save a bird some trouble,if they evolve in the right environment. "any
island rails are flightless because small
island habitats without predators eliminate
the need to move long distances. Flying is
difficult, and ma#es intense metabolic
demands of a bird. "uscles used to fly can
ta#e up a large portion of bird$s weight, and
giving it up can save a bird in energy
expenditures. Flightlessness can ma#e it
easier to survive and colonize an oceanic
island where food and resources may belimited.
The sum total of what we #now about the Tahitian Red-%illed Rail comes from a specimen
pic#ed up by &ohann Reinhold Forster, famous naturalist on 'aptain &ames 'oo#$s second
voyage.
