  2. African Forest
    Elephant
    Status - CR
    • Places: Congo Basin
    • Habitat: Forest Habitat (Dense Tropical Forest)
    • Their populations declined by 62% between 2002 and 2011
    • During that period, the species also lost 30% of its geographical range.
    • As this downward trend continues, the African forest elephant was declared
    Critically Endangered by the IUCN in 2021.

  3. African Forest Elephant
    - Why are they
    important?
    • Forest elephants are found in
    dense forests and are essential
    for the germination of many rain
    forest trees.
    • The seeds of these trees only
    germinate after passing through
    the elephant’s digestive tract.

  4. African Forest Elephant
    - Threats
    Habitat Loss and Habitat Fragmentation
    • Due to conversion of forests for agriculture, livestock
    farming, and human infrastructure.
    • African elephants have less room to roam than ever
    before as expanding human populations convert land
    for agriculture, settlements and developments.
    • Poverty, armed conflict and the displacement of
    people by civil conflict also add to habitat loss and
    fragmentation.
    • The above reasons push elephants into smaller
    islands of protected areas and hinder elephants’
    freedom to roam.
    • The elephants’ range shrank from three million
    square miles in 1979 to just over one million square
    miles in 2007.

  5. African Forest Elephant
    - Threats
    Poaching for Ivory
    • Forest elephants are primarily threatened by
    poaching for bushmeat and ivory.
    • Tens of thousands of elephants are killed each
    year to meet the illegal international demand
    for ivory.
    • Commercial logging, plantations for biofuels and
    extractive industries like logging and mining not
    only destroy habitat but also open access to
    remote elephant forests for poachers.
    • In January 2012, over 200 elephants were
    slaughtered in a raid by invading Sudanese
    poachers in a single national park in Cameroon.
    • Many governments do not have adequate
    financial or human resources to protect their
    elephants, conduct regular population estimates
    or enforce regulations.

  6. African Forest Elephant
    - Threats
    Increased Human-elephant conflict
    • As habitats contract and human
    populations expand, people and
    elephants are increasingly coming into
    contact with each other.
    • Where farms border elephant habitat or
    cross elephant migration corridors,
    damage to crops and villages can
    become commonplace.
    • This often leads to conflicts that
    elephants invariably lose.
    • But loss of life can occur on both sides,
    as people may be trampled while trying
    to protect their livelihoods, and game
    guards often shoot "problem" elephants.

  7. African Forest Elephant
    - Measures taken for conservation
    Stopping poaching
    • WWF strives to eliminate illegal hunting in protected areas
    • They advocate for sustainable hunting of less vulnerable species in buffer
    zones
    • This also provides affordable meat to a poor and growing human
    population
    • They brought together neighboring countries in the Congo Basin to join
    forces to protect wildlife from poaching
    Tackling illegal trade
    • WWF and TRAFFIC(world’s largest wildlife trade monitoring network),
    support a Central African Forest Commission commitment to put a
    groundbreaking regional network called PAPECALF into place that will
    strengthen law enforcement and better combat poaching of species at
    risk from illegal wildlife trade
    • Cases will also be monitored for corruption, and action taken against
    anyone attempting to impede justice

  8. Bornean Orangutan
    Status - CR
    • Places: Borneo and Sumatra
    • Habitat: Forest Habitat (Lowland rainforests and tropical, swamp and mountain forests)
    • Populations have declined by more than 50% over the past 60 years
    • The species' habitat has been reduced by at least 55% over the past 20 years.
    • Northwest Bornean orangutans are the most threatened subspecies, a mere 1,500 individuals or so
    remain.

    View Slide

  9. Bornean Orangutan
    - Why are they
    important?
    • Orangutans play a critical role in
    seed dispersal, keeping forests
    healthy.
    • Over 500 plant species have been
    recorded in their diet.

    View Slide

  10. Bornean Orangutan
    - Threats
    • Human threats
    • Hunting
    • Unsustainable and often illegal logging and mining
    • Conversion of forests to agriculture.
    • Catastrophic events
    • The 1997-98 forest fires in Kalimantan, which killed up to 8,000
    individual orangutans.
    • Young orangutans are in demand for a flourishing pet trade, with each animal
    fetching several hundred dollars in city markets on nearby islands.
    • Studies have indicated that 200-500 orangutans from Indonesian Borneo
    alone enter the pet trade each year.
    • This represents a real threat to wild orangutan populations as orangutans
    have an extremely low reproductive rate.
    • There is also trade in orangutan parts in Kalimantan, with orangutan skulls
    fetching up to $70 in towns.

    View Slide

  11. Bornean Orangutan
    - Measures taken for
    conservation
    Addressing the illegal killing and trade of orangutans
    • WWF works closely with TRAFFIC, the wildlife trade
    monitoring network, to help governments enforce the
    laws that prohibit orangutan capture and trade. This
    work includes strengthening the capacity of rangers,
    prosecutors and customs officers to identify, investigate
    and prosecute wildlife crimes
    Reducing human-orangutan conflicts
    • They work with the governments, local
    communities, plantation owners and indigenous Dayak
    people to help develop plantation management
    methods that do not affect orangutans.
    • They also assist with regional land use planning to
    ensure that agricultural areas are developed as far away
    from orangutan habitat as possible.

  12. Hawksbill Turtle
    Status - CR
    • Places: Mesoamerican Reef, Coastal East Africa, Coral Triangle
    • Habitat: Oceans

    View Slide

  13. Hawksbill Turtle
    - Why are they
    important?
    • Hawksbills help maintain the health of coral
    reefs. 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 residents
    in the Coral Triangle, the flow of visitors
    who come to admire turtles is a vital source
    of income.
    • They are a fundamental link in marine
    ecosystems and help maintain the health of
    coral reefs and sea grass beds.

    View Slide

  14. Hawksbill Turtle
    - Threats
    Like other sea turtles, hawksbills are threatened by the
    loss of nesting and feeding habitats, excessive egg
    collection, fishery-related mortality, pollution, and
    coastal development. However, they are most
    threatened by wildlife trade
    Wildlife trade
    • Despite their current protection under the
    Convention on International Trade in Endangered
    Species of Wild Fauna and Flora (CITES) and many
    national laws, there is still a disturbingly large
    amount of illegal trade in hawksbill shells and
    products.
    • They are much sought after throughout the tropics
    for their beautiful brown and yellow carapace plates
    that are manufactured into tortoiseshell items for
    jewelry and ornaments.

    View Slide

  15. Hawksbill Turtle
    - Threats
    Fisheries Bycatch
    • Hawksbills are particularly susceptible
    to entanglement in gillnets and
    accidental capture on fishing hooks.
    • Sea turtles need to reach the surface
    to breathe, and therefore many drown
    once caught.
    • Known as bycatch, this is a serious
    threat to hawksbill turtles. As fishing
    activity expands, this threat is more of
    a problem.

    View Slide

  16. Hawksbill Turtle
    - Measures taken for conservation
    Eliminating Bycatch
    • WWF aims to reduce turtle bycatch by working with
    fisheries to switch to more turtle-friendly fishing hooks
    ("circle" hooks) and advocates for the use of special turtle
    excluder devices in nets
    • They track turtle movements using satellite to help prevent
    future interactions between fisheries and turtles
    Protecting sea turtle habitat
    • WWF works around the world to establish marine
    protected areas (MPA) to ensure sea turtles have a safe
    place to nest, feed and migrate freely

    View Slide

  17. Hawksbill Turtle
    - Measures taken for conservation
    • Addressing Wildlife Trade
    • WWF works with communities to reduce turtle harvesting and local trade in
    the Coral Triangle
    • They work to develop alternative livelihoods so that local people are no
    longer dependent on turtle products for income
    • WWF also works to stop the illegal trade of hawksbill products around the
    world through TRAFFIC

  18. Amur Leopard
    Status - CR
    • Place: Amur-Heilong
    • Habitats: Temperate, Broadleaf,
    and Mixed Forests

    View Slide

  19. Amur Leopard
    - Why are they important?
    • The Amur leopard is important
    ecologically, economically and
    culturally. Conservation of its
    habitat benefits other species,
    including Amur tigers and prey
    species like deer

    View Slide

  20. Amur Leopard
    - Threats
    Illegal Wildlife Trade
    • The Amur leopard is poached largely for its
    beautiful, spotted fur.
    • In 1999, an undercover investigation team
    recovered a female and a male Amur leopard
    skin, which were being sold for $500 and
    $1,000 respectively in the village of Barabash.
    • Agriculture and villages surround the forests
    where the leopards live. As a result, the forests
    are relatively accessible, making poaching a
    problem.
    Prey Scarcity
    • In China, the prey base is insufficient to sustain
    large populations of leopards and tigers.

    View Slide

  21. Amur Leopard
    - Measures taken
    for conservation
    Stopping poaching and trade
    • WWF supports antipoaching work in all Amur leopard
    habitat in the Russian Far East and in known leopard
    localities in northeast China.
    • They implement programs to stop the illegal trade in
    Amur leopard parts. Together with TRAFFIC, WWF help
    governments enforce domestic and international trade
    restrictions on Amur leopard products.
    Monitoring populations
    • WWF monitors Amur leopard populations and its habitat.
    • They also work to increase the population of leopard
    prey like roe deer, sika deer and wild boar including
    releasing such deer into new reserves in China to provide
    founder animals to rebuild prey populations.

  22. Amur Leopard
    - Measures taken for conservation
    • A Safe Haven
    • Amur leopards received a safe haven in 2012 when the government of Russia
    declared a new protected area. Called Land of the Leopard National Park, this
    marked a major effort to save the world’s rarest cat.
    • Extending nearly 650,000 acres it includes all the Amur leopard’s breeding
    areas and about 60 percent of the critically endangered cat’s remaining
    habitat.

  23. Waved Albatross
    Status - CR
    • Place: Galapagos Islands
    • Habitat:

    View Slide

  24. Waved Albatross
    -Threats
    • Fishing
    • Long-line fishing boats lay out hundreds of
    miles of baited hooks which attract birds
    and once they try to eat the bait they get
    hooked and drown after being dragged
    under.
    • Plastic pollution
    • They are also likely to be at threat from
    marine plastic pollution.
    • Other threats
    • Other threats include water pollution, oil
    slicks and chemicals.

    View Slide

  25. Waved Albatross
    -Measures Taken
    for conservation
    • The population of waved
    albatrosses on the Galápagos is
    protected by national park
    personnel, and the island is also
    categorized as a World Heritage
    Site

  26. Hula bream(Acanthobrama
    hulensis)
    Status - EX
    • Places: Lake Hula in northern Israel
    • Habitat: Freshwater lakes and Swamps
    • They were a species of ray-finned fish in the family Cyprinidae

    View Slide

  27. Hula bream(Acanthobrama hulensis)
    - Why are they extinct?
    • The deliberate draining of Lake Hula in the 1950s led to the extinction
    of this species.

  28. Dodo
    Status - EX
    • Place: Mauritius
    • Larger than turkeys, dodos
    weighed about 23 kg (about 50
    pounds) and had blue-gray
    plumage and a large head.

    View Slide

  29. Dodo
    -Why are they extinct?
    • The birds were unfazed by the Portuguese sailors that discovered
    them around 1507.
    • These and subsequent sailors quickly decimated the dodo population
    as an easy source of fresh meat for their voyages.
    • The last dodo was killed in 1681

  30. Steller’s Sea Cow
    Status - EX
    • Place: Komandor Islands in the
    Bering Sea
    • Habitat: Coastal waters
    • Steller’s sea cows reached a
    length of 9–10 meters and
    weighed around 10 metric tons

    View Slide

  31. Steller’s Sea Cow
    -Why are they extinct?
    • They had only very little ability submerge.
    • This made them easy targets for the harpoons of Russian seal hunters, who
    prized them as a source of meat on long sea journeys.

    View Slide

  32. Wooly Mammoth
    Status - EX
    • The woolly mammoth is the best-
    known of all mammoth species.

    View Slide

  33. Wooly Mammoth
    - Why are they extinct?
    • While climate change definitely played a significant role in their
    extinction, recent studies suggest that humans may have also been a
    driving force in their demise.
    • Extensive hunting and the stresses of a warming climate are a lethal
    combination, and it seems even the mighty mammoth could not
    withstand the human appetite in a changing world.

  34. Passenger Pigeon
    Status - EX
    • Places: North America

    View Slide

  35. Passenger Pigeon
    - Why are they extinct?
    • As American settlers pressed westward, passenger pigeons were
    slaughtered by the million yearly for their meat and shipped by
    railway carloads for sale in city markets.
    • Hunters often raided their nesting grounds and annihilated entire
    colonies in a single breeding season.
