Tulap Sea Turtle Project
Masarang Turtle Hatchery and
Coastal Community Development
Tulap Sea Turtle Project
• A project of Masarang Foundation
under management of Tasikoki Wildlife
Rescue Centre
• Activities started with volunteers in
2010 and with full-time staff since
March 2011
• Collaboration with international sea
turtle conservation experts and local
community
Project Aims
• To maximise the number of sea turtles
successfully nesting at the beach area of
Tulap-Toloun
• To maximise the successful incubation of
the eggs at the correct temperature for
natural gender ratio
• To enable hatchlings to reach the sea
under natural conditions, to promote their
chances to adulthood
• To develop harmony between coastal
villages and the coastal ecology
Turtle High 5!
While you watch
the short film on the
ecology of turtles,
you need to write

Destructive Fishing
Destructive fishing affects the sea turtles habitat, food chain and directly kills many
turtles
• Trawler nets
• Reef damage / mooring / fishing / dynamite fishing / cyanide fishing
• Sea grass damage from dragnet fishing
Poaching of Nests and
Turtles
Lack of effective law enforcement often quoted for main issue of all illegal poaching
According to Indonesian law UU#5/1990; all species of sea turtles, their nests
and eggs are protected and may not be interfered with unless under specific
licence to do so for approved conservation or research purposes.
Beachfront Development
• Example batu putih wall
• Example house near pantai kawis
Light Pollution
Newly hatched sea turtles seek the light of the horizon to find the sea
at night and can be disorientated by beachfront lighting from
villages and resort hotels
Coastal & Oceanic
Pollution
Also chemicals from agriculture fertilisers, pesticides, fuels / oil, etc

Written analysis - Describe and
explain your results/graph.
• Describe the main types/categories of waste
found on the beach shown in your graph/s, use
numbers in your descriptions about the
amounts of different waste categories.
• Could also use annotated PHOTOS describing
and explaining cause and consequences of
the problem.
• What are the origins of the waste - Hong Kong?
China? elsewhere? how did it get into the sea?
Written analysis - Describe and
explain your results/graph.
• What are the causes of these types of waste?
(paragraph that describes the sources and
reasons for a couple of waste types being
found on the beach)
• Explain the types of problems that this waste
creates?(at least 2 problems - how does it
affect plants and animals, ecosystems, humans
etc)
How can the problem of
plastics in our seas be
tackled?
In order to do this we must first understand the different stakeholders
and how they are affected by the problem and might solve the
problem.
Stakeholders
• Hong Kong Fishermen
• Local Residents of Discovery Bay
• Government of HK
• Park & Shop
• Green Groups – WWF & Plastic Free Seas
• Governments of other countries in the region
• Soft drinks manufacturers in China
• Global citizens
How are they all affected by plastic in the seas?
How might they tackle the problem?
Reduce, Reuse, Recycle

Problem:
Soft drinks bottles and

killing animals , polluting
water with toxins,
entering the food chain
Solution:
Ban plastic drinks bottles
This type of strategy is to
reduce the quantity of
plastics that could enter
our oceans.
San Francisco (US) city
government has
banned the sale of
single use small plastic
bottles from its
government buildings
and premises. including
street fairs
By banning
Plastic bottles this
would benefit the
city- reducing waste
in the city,
particularly if
citizens were
encouraged to use
their own re-
useable bottles to
fill up from water
fountains.
Plastic
manufacturers
may suffer in
the short term

1. What solutions have you discussed?
With your partner feedback to each other
focusing on critical evaluation of their 2
solutions/ideas to the problem of plastic in the
seas.

You will now start to write
your letter to the HK
environment secretary to
outline your ideas about
how the problem of
plastic in our seas can be

Letter Writing - Structure
What are the components of a formal letter?
1) Your Address
The return address should be written in the top
right-hand corner of the letter.
2) The Address of the person you are writing to
The inside address should be written on the left, starting below your address.
3) Date:
You can write this on the right or the left on the line after the address you are writing
to. Write the month as a word.
4) Salutation or greeting:
Dear Mr. Wong,
If you know the name, use the title (Mr, Mrs, Miss or Ms, Dr, etc.) and the surname only.
5) Ending a letter:
a) Yours Faithfully
If you do not know the name of the person, end the letter this way.
b) Yours Sincerely
If you know the name of the person, end the letter this way.
c) Your signature
Sign your name, then print it underneath the signature. If you think the person you are
writing to might not know whether you are male of female, put you title in brackets
after your name.
So what do I write in the middle?
Exemplar paragraph for sleeping policeman idea.
I have two ideas for dealing with the problem of speeding traffic. Speeding traffic can be slowed by the use of
sleeping policeman. These are bump type structures, often made of concrete and tarmac, which are built on
roads which are designed to force drivers to slow down. These structures have been used successfully in Hong
Kong and in numerous cities around the world, studies in the UK have shown that speed bumps result in 18 %
reduction in traffic volumes and an average 13% reduction in traffic collisions. Sleeping Policemen slow traffic
down making it less likely that accidents will occur.
One of the advantages of sleeping policeman is that they are relatively low cost as they only require an asphalt or
tarmac structure. They do not require constant supervision from policeman or expensive traffic speed cameras. This
would work in areas of Hong Kong which have relatively slow moving traffic. Local Residents would be pleased
that traffic is slower and the likelihood of accidents is less.
One of the disadvantages of sleeping policeman is that vehicles will travel slower this may create slower flowing
traffic and this could cause congestion, which may actually increase air pollution. They are likely to result in
increased gases like Carbon Monoxide and Nitrous oxides which are harmful to human health in local areas. They
can result in increasing levels of respiratory disease such as asthma. They can also slow down emergency vehicles
which may result in longer response times for ambulances and this may cost lives. Local businesses may also be
disappointed because delivery vans may be slowed down.
Sleeping policemen cannot be used in areas where the traffic is meant to flow at high speeds such as on
motorways as it would be dangerous and damaging to vehicles.
Another strategy to reduce speeding traffic is to …..
