There are several reasons that contribute to the decline in numbers of the giant panda.
1. Habitat
encroachment and destruction is the main threat facing the pandas today.
2. Pandas
become ensnared in traps farmers set for other animals
3. Poaching,
illegal hunting. A panda skin can get sell for $100,000-$200,000 on the
black markets in the far east. The punishment for poaching a giant panda
in China: Life in Prison
4. Low reproductive
capacity of the giant panda make it difficult for them rebound quickly
from low numbers.
5. Mass die
out of bamboo with no alternative food source
The populations are becoming smaller and more isolated which have several affects on the panda. First, bamboo usually reproduces by vegetative growth (asexual means) but when the bamboo flowers (sexual means) in synchrony there is a mass die off of the bamboo. Usually, when this occurred the panda would simply move to another area and switch to another bamboo that was not flowering. With the reserves being isolated the giant panda is not free to move and gain access to an alternate bamboo patch. Secondly, the genetic diversity of the populations is declining. The small populations offer little diversity in genetic material leaving and going into a population leaving them vulnerable to genetic problems.
People
are trying to save the pandas, they:
1. Creation
of 14 new panda reserves for a total of 26 panda reserves.
2. Corridors,
forest links, between the isolated populations are being constructed to
help increase the range in which the panda lives. It is hoped that exchange
of genetic material between wild populations will increase.
3. Conservation
education and public awareness activities
4. International
breeding programs in zoos around the world.
5. Artificial
insemination of pandas to try and increase the numbers, this has had little
success.
