SEA TURTLE POACHING

Slide 1 - Tekstslide

This lesson is provided by Sea Shepherd.  Sea Shepherd was founded in 1977 and is a marine conservation organisation working to protect the oceans and marine wildlife.  Sea Shepherd works globally on a range of issues impacting the oceans, running numerous direct action campaigns each year.  Sea turtle poaching is one area Sea Shepherd is working on to help stop sea turtles becoming extinct.

Slide 5 - Video

Empty ocean by 2050
Scientists estimate that by 2050 the ocean ecosystem will be on the verge of collapse, empty of fish and marine wildlife, unless urgent action is taken on the issues impacting on the oceans and marine wildlife.

What do you think are the
main reasons why sea turtles
are endangered?

Slide 13 - Woordweb

Ask students to answer the following question using www.LessonUp.app or discuss in the classroom.  

“What do you think are the main reasons why sea turtles are endangered?”


Why sea turtles are endangered?

These include:
-    Plastic pollution
-    Oil spills
-    Coastal development impacting nesting
-    Costal development taking away habitat and food.
-    Climate change
-    Entanglement in ALD fishing gear
-    Bycatch by commercial fishing
-    Poaching


Slide 14 - Tekstslide

Why sea turtles are endangered
There are a number of issues impacting on sea turtles.
These include:
➢    Plastic pollution
➢    Oil spills
➢    Coastal development impacting nesting
➢    Costal development taking away habitat and food.
➢    Climate change.
➢    Entanglement in ALD fishing gear
➢    Bycatch by commercial fishing
➢    Poaching

Today we will be focusing on poaching.

Why do you think sea turtles
are taken by poachers?

Slide 15 - Open vraag

Sea turtle poaching
Ask students to answer the following question using www.LessonUp.app or discuss in the classroom.  

Why do you think sea turtles are widely taken by poachers?
(What do they use them for?)

For turtle meat, eggs and
the shells to make ornaments.
For turtle meat, eggs and the shells to make ornaments.

Slide 16 - Tekstslide

Sea turtle poaching
The main reasons for sea turtle poaching are:
➢    Turtle meat.
➢    Eggs taken for food.
➢    Shells – used to make ornaments and jewellery, often for tourists.

Slide 17 - Tekstslide

Nesting sea turtles
Ask students when they think poachers are more likely to target sea turtles?

Answers:
➢    Female turtles come ashore for nesting season, where they lay their eggs on beaches.
➢    Sea turtles are slow moving and spend time digging a nest and laying eggs, then bury the eggs before heading back to sea. Poachers can wait until the eggs are laid and then attack the female turtle.


How do you think poachers know where
and when to find sea turtles?

Slide 18 - Open vraag

Ask students to answer the following question using www.LessonUp.app or discuss in the classroom.  

“How do you think poachers know where and when to find sea turtles?

Female turtles use the same beach to nest on where they were born.
International laws regulate fishing.
Female turtles use the same beach to nest on where they were born.

Slide 19 - Tekstslide

Nesting sea turtles
Female turtles will use the same beaches to nest on, often where they were born.

Nesting season is also a regular occurrence, so poachers come to know what time of year to watch for sea turtles and the beaches to monitor.



How does poaching from nesting beaches increase the risk of sea turtles becoming endangered or extinct?

Slide 20 - Open vraag

Ask students to answer the following question using www.LessonUp.app or discuss in the classroom.  

“How does poaching from nesting beaches increase the risk of sea turtles becoming endangered or even extinct?”

Taking eggs takes away the
next generation of sea turtles.
Taking eggs takes away the next generation of sea turtles.

Slide 21 - Tekstslide

Increasing risk of extinction
Poachers are effectively only taking female turtles that are reproducing, laying eggs.

They also often take the eggs – killing the next generation of sea turtles.

Only 1 in 1000 sea turtles survive from the eggs hatched to adulthood.

Protecting sea turtles around the world.

Slide 22 - Tekstslide

Where are sea turtles hunted?
Sea turtles are hunted in many places around the world.

For example in places like Japan, the Western Pacific and Cuba, Hawksbill Turtles are killed for their colourful shell to make jewellery, hairbrushes, combs and other items. Tourists and local people buy these items.

Sea Shepherd runs campaigns to protect sea turtles. These have been in: Costa Rica, Nicaragua, Mayotte, Italy, Honduras, Florida (USA), Barbuda, Antigua and Cabo Verde.

Sea Shepherd Case Studies provide additional learning on some of these locations.

INTERNATIONAL LAW
& CITES

CITES - Convention on International Trade of Endangered Species, requires that countries who have signed up to CITES must prohibit any trade in sea turtles or anything made from them.

Individual countries may also have their own laws to protect sea turtles.


Slide 23 - Tekstslide

Protecting sea turtles
How can we protect sea turtles from poachers?

International laws say it is illegal to carry sea turtle parts or products between countries.  Thus most poaching is for local purposes only.

CITES - Convention on International Trade of Endangered Species, requires that countries who have signed up to CITES must prohibit any trade in sea turtles or anything made from them.

Individual countries may also have their own laws to protect sea turtles.

Patrolling beaches to protect nesting turtles.

Slide 24 - Tekstslide

Patrolling beaches
Conservation groups, like Sea Shepherd and local activists, patrol beaches to protect nesting turtles from poachers.

In high risk areas sea turtle eggs are removed from the nest and are taken to hatcheries where they can be kept safe until they hatch and can then be returned to the ocean.

How do you think you can
help protect sea turtles?

Slide 25 - Woordweb

How do you think you can help protect sea turtles
Ask students to answer the following question using www.LessonUp.app or discuss in the classroom.  

“How do you think you can help protect sea turtles?”


How can you help
protect sea turtles?

Help stop the use of turtle eggs and meat by spreading awareness.

Never purchase products made from turtle shells.

Do not disturb nesting turtles, nests or hatchlings

Slide 26 - Tekstslide

How do you think you can help protect sea turtles?
Some ways you can help include:
➢    Help stop the use of turtle eggs and meat by spreading awareness.
➢    Never purchase products made from turtle shells.
➢    Do not disturb nesting turtles, nests or hatchlings.
How can you help
protect sea turtles?
     If visiting nesting beaches ensure you remove your beach equipment. Eg. Beach chairs, umbrellas and children’s toys, so turtles can come ashore and hatchlings find their way to the ocean.

    Be sure to knock down sandcastles before you leave because they become obstacles for nesting turtles or new hatchlings.
    Don’t drive on nesting beaches, so as not to destroy eggs.

Slide 27 - Tekstslide
