Throughout history the divergence, degradation and destruction of wetland ecosystems have threatened crane habitat around the world, including the Platte River in Nebraska, and the Guadalupe and San Antonio Rivers in Texas, USA, vital migration and wintering habitats for sandhill cranes and the world's endangered Whooping Cranes. Wetlands are often considered wastelands, areas to be modified for human consumption, development, and agriculture, despite the wetland ecosystem's important role in maintaining water quality and environmental health.
The Ussuri, Lena, and Amur Rivers of North East Asia, are fed by the boreal wetland ecosystems of the Xang'an Mountains, which remain one of the last remote wildernesses of the area. But wetlands are being lost in China faster than any other land type, especially lands desired for agriculture. The greatest increase in agricultural lands, through the conversion of wetlands to agricultural usage, between 1990 to 2000, occurred in the Xing'an Mountains, a primary breeding habitat for the Hooded Crane.
Dr Guo Yumin, of the Beijing Forestry University, and his team of Chinese and Russian scientists, are studying the breeding biology of the hooded crane and teaching area communities about the value of this species. Below, you see one of the hundreds of annual calendars distributed in local communities to educate and raise awareness about Hooded cranes and their habitat.

The chief threats to the Hooded Crane and its habitat include: Russia and Mongolia--loss of habitat due to the construction of gold mines and reservoirs; China--illegal hunting, poisoning and reclamation of forest wetlands; Japan--over crowding of the species on wintering grounds threatening disease.
The good news is, Dr Yumin and his team, in partnership with the Whitley Fund for Nature and Grus Monacha International Aid, have been influencing change in the hooded crane's habitat through research and the education of local governments, communities, and businesses.
Successful strategies for influencing gold mining in China are now helping scientists influence relevant parties in Russia, reducing the impact of mining on the Hooded Crane's habitat. The State Forestry Bureau of China has established two Nature Reserves in Hooded Crane breeding habitat with the goal of management for the long-term as a result of Dr Yumin's team's conservation efforts. And in Japan, scientists are studying methods of decentralization for the hooded crane population on its wintering grounds and determining ways to improve habitat management.
Though much has been accomplished over the past several years, Dr Yumin affirms that hard work is yet to come. "The hooded crane still faces many threats, our protection work [has] a long way to go."
Next: Keeping and Informed Eye on America's Hooded Crane. Dr Yumin shows us how to distinguish individual Hooded cranes.
This is the second post in a three-part series on the endangered Hooded Crane and its appearance in North America. To see all the posts in this series visit: America's Hooded Crane. The first post will appear last.

Here in our county in SW IN there are many little snatches of wetlands that are being helped back to their natural state. It is encouraging to see. I always wondered what the Farmers were thinking when they tried to drain these areas and plant them with crops becasue most were along rivers. Just crazy. I am sure all wildlife appreciate the work.
ReplyDeleteAnother marvelous lesson learned about these wonderful birds Vickie. Thank you for this!
ReplyDeleteA very nice post.Habitats are being threatened around the world.I'm glad to see some positive actions happening.
