Top best answers to the question «Why is the baiji dolphin endangered»

  • Rapid economic development of the Yangtze River Basin caused extensive habitat degradation. The baiji faced a range of threats from human activities, especially bycatch and habitat destruction. A lethal combination of threats killed far more baijis each year than were being born, and caused an extraordinarily fast decline in baiji numbers.

The baiji is one of only a few dolphin species that is known to have adapted from the ocean to a freshwater environment. The likely cause of the baiji's decline is from the use of fishing nets with hooks that snag and drown the dolphins as bycatch. Other causes may include habitat degradation.

  • Most pointedly, and primarily dolphin threats are a result of human activities and their related impacts. In recent history the Baiji, also known as the Yangtze river dolphin, was declared critically endangered, its river habitat ruined by the construction of dams and the invasion of boat traffic.
  • Threats to river dolphin populations include pollution, subsistence hunting, industrial development, dam construction, riverbank deforestation, over fishing, and incidental capture in commercial fisheries. Why is the baiji endangered? Varying water levels in the Yangtze River due to industrial development have limited available habitat.
  • Baiji Dolphin Conservation Status and Threats. There has been quite a decline in the number of these dolphins due to the industry booming in China and that is a huge concern. The river they live in has been used for a variety of transporting needs, for commercial fishing, and even the introduction of hydroelectricity.
