Paige Sprague Diversity of Life NRM 2307 Benefit of the Doubt (Article at bottom of page) The Panda’s Decline This article gives some new meaningful insight on the wild Pandas. Serious destruction to their habitats is a great cause of concern. Estimates of the number of wild pandas found recently appear alarmingly low. The depletion worries those concerned about these great bears. Isolation, gender ratios, deforestation, and hunters plague the panda’s attempts to survive in their natural habitat. This information relates to biodiversity and the current class, giving me some further insight. Areas have been set aside in areas of China but these reserves lack proper sustainability for the panda bears. One reason these reserves fall short of providing proper habitat is their isolation. Pandas tend to roar a large area and the reserve prevent pandas from migrating to new territories. They are isolated to groups often smaller than twenty. Small populations cause inbreeding which reduces reproductive fitness within that population. Also, people are allowed to live on these reserves and farm and set traps. Often pandas become unintended victims of these traps. If the only female or male in a population is killed, the population fails to reproduce and will not survive. Another problem is although bamboo may be abundant; deforestation prevents the pandas from settling in an area. Trees on reserves that are not protected from timber men are often harvested. Pandas prefer tree coverage and will migrate away from bamboo that isn’t densely surrounded by trees. Captive breeding programs using artificial insemination have also been implemented to try to further restore panda numbers. It has been successful to a point although pandas are very sensitive to captive breeding and many young die before they even reach two months of age. The young are incredibly vulnerable and sometimes weigh “less than five ounces.” The female is

Paige Sprague Diversity of Life NRM 2307 Benefit of the Doubt (Article at bottom of page) only in season for a very short period of time each year. These are why panda’s numbers have been dwindling despite many efforts. This article applies to many things we have been learning. It shows why biodiversity is so important. Without a larger number of pandas, they will become inbreed and eventually die off. They need a greater amount of genetic diversity and a larger habitat. Their young also need a lot of care from their mothers. If the mothers are becoming stressed in these unsustainable habitats, it will decrease the baby’s chance of survival greatly. I thought this was a very interesting article and useful towards the knowledge I have gained during my time in diversity of life. INTENSE SCIENTIFIC EFFORTS FAIL TO REVERSE THE
