1. Nonrenewable Plants and Animals Due to Extinction

2. Passenger Pigeon early 1800s over-hunting 1900 1914
existed in huge flocks (billions) all over North America.
over-hunting
using increasingly effective methods to catch both mature and juvenile birds
led to rapid extinction
1900
last bird recorded in the wild
1914
the last Passenger Pigeon died in the Cincinnati Zoo

3. Carolina Parakeet Extinction due to:
challenges to its diet
large flocks of these birds fed on fruit and grain
farmers were protective of their crops
challenges to its habitat
destruction of the birds’ forest habitats
bright set of feathers
sought after as hat accessories
The last of them, a captive specimen in the Cincinnati Zoo, died in 1918.

4. Toolache Wallaby Common in Australia until 1910
population slowly dwindled
hunting
prized for its fur
game trophy
predation by foxes
habitat destruction
1924
few individuals lived in the wild
1982
numerous surveys failed to observe any remaining specimens
species declared as extinct

5. Thick-billed Ground Dove
was identified only from two specimens collected from the Solomon Islands in 1882 and in 1927
Its decline is thought to be due to:
new predators being introduced into its habitat
the destruction of forests in which it lived
after unsuccessful attempts to find the bird, it was designated extinct status in 2005

6. St. Helena Olive flowering plant endemic to the island of St. Helena
1977
only one tree was found in the wild
a single cutting was successfully cultivated
the tree died in 1994
the survival of the species depended on a handful of seedlings derived from the cultivated cutting that eventually perished
last of the species died in December 2003
factors responsible for its extinction:
Deforestation
over-grazing
the tree’s self-incompatibility

7. Arunchal Hopea Tree small tree
harvested extensively for the construction of house posts in India
declared extinct in 1998
