There are many issues currently facing the Bengal Tigers that are
pushing this species towards extinction. Here will be addressed a few of the
major ones:
Habitat Loss.
This biggest negative impact being faced by the Bengal Tiger is their
loss of habitat. Due
to human development and habitat fragmentation, these animals have become
confined to small, isolated patches of habitat that are not even completely
idea conditions for these animals (Global Tiger Recovery Program, 2010). As their overall habitat amounts decrease,
this will cause numbers to continually decline and can eventually lead to the
extinction of these Tigers.
Deforestation has caused a decrease in these Tigers' habitat
Poaching.
Poaching has become a huge problem for the Bengal Tiger. Although this
poaching is illegal, there has become a high demand for parts of these animals
and this demand continues to drive poachers to hunt and kill these animals. In fact, a dead tiger is worth a total of about $30,000 once all its parts have been sold (Dinerstein, 2012). In
addition, although there are laws against hunting Bengal Tigers, these laws are
not enforced well and poachers often go unpunished ("India's Tiger Poaching Crisis," 2012). Because of this lack of
government enforcement and punishment, poachers continue to go after these
Tigers and take away from the few amounts of these animals left.
Evidence of Bengal Tiger poaching
Human Impact.
The human population continues to increase and in order to meet these
increasing numbers, more and more of the Bengal Tiger habitat is being
developed to accommodate humans. Not to mention that humans are even extending
their reach into portions of land that have been set aside for the purpose of
conserving Tigers (Seidensticker, 2010). This presence of humans causes extra stress on this species
and can further decrease their roaming range, making it harder to find other
Tigers to mate with. There have been few records of Tigers killing humans, but
it can occur. Especially when the Tigers are having all their other prey
options removed. There is a serious need for balancing the needs of Tigers and
humans so these animals can be protected while limiting the risk to humans.
Human presence has a huge impact on these Tigers
Loss of Genetic Diversity.
Although there have been multiple areas of land designated for
maintaining Bengal Tiger habitat, these areas tend to be fairly small and
spread out. This creates independent, isolated Tiger populations where the
individuals cannot breed with other Tigers. This is creating metapopulations
and decreasing the genetic variability within these populations of Tigers. This
has the potential to lead to inbreeding depression or the bottleneck effect
within the individuals of these metapopulations. This decrease in genetic
diversity has the potential to decrease the overall fitness of these tigers and
make them more susceptible to having these small populations being individually
wiped out (Groom, 226).
Evidence of the sort of features that can come from genetic inbreeding
Great information! But again, I think you are confusing some facts of the Bengal tiger with the entire tiger family. For the habitat loss part, you stated that the bengal tiger was known to roam into russia. I don't know if thats true. If I recall correctly, the bengal has had its historical range only in the indian subcontinent (india, nepal, bhutan, bangladesh, and maybe china and indo china), but not russia. Russia is home to the Siberian tiger.

Good description on threats - and great photos to support the discussion.
ReplyDeleteGood job. I have a question... how many Bengal tigers were killed from habitat loss?
ReplyDeleteHey.... Google it. Nothing you can't find on Google:)

DeleteI am doing a bengal tiger blog too and this is sooo helpful I love this blog
ReplyDeleteHi. Are you writing a blog on Bengal Tigers too? May I please have the address? I am doing a research on Bengal Tigers and would appreciate your contribution.
DeleteThanks
Dear Blogger, Can you please provide your bibliography for this post?

ReplyDeleteBengal Tigers are only remaining a few in India. If the government will don't see in this matter then one day we will lost them. There are a few tiger safaris in India who trying to save these wild cats but it is totally not enough. we all should try something to save these from danger.
