In China, there was once one species that was rarer and more endangered than the giant panda, and that was the crested ibis. In 1981, researchers discovered the world's only 7 remaining wild crested ibises in the depths of the Qinling Mountains in Yangxian County, Shaanxi Province, thus opening the prelude to crested ibis conservation. In the past 40 years, from "discovery" to "protection", "reproduction" and "rejuvenation", the wild crested ibises in Yangxian County have grown to more than 3,000.
The Crested Ibis Breeding and Breeding Center is one of the important institutions of the Hanzhong Crested Ibis National Nature Reserve in Shaanxi Province, and can be called a national treasure "conservation institute". 40 years ago, after the world's only 7 remaining wild crested ibises were discovered, researchers conquered and explored a set of mature breeding and breeding technology systems, and successfully bred thousands of crested ibises.
The crested ibises that grow up in the breeding and breeding center will be sent to the flying greenhouse to be tested by the simulated environment. In order to solve the problem of the unity of crested ibises, Since 2004, Shaanxi has successively carried out rewilding and release activities in the northern and southern regions of the Qinling Mountains. Ren Wenming, a staff member of the Crested Ibis Breeding and Breeding Center of the Shaanxi Hanzhong Crested Ibis National Nature Reserve Management Bureau, said in an interview with a knews reporter who read the news: "The crested ibis is very sensitive to the wild environment, such as a tall tree, after the tree nests, there are people grazing herding and cutting firewood at the bottom, if the environment is destroyed, it will not go."
In order to provide the crested ibises with an undisturbed wild environment, Shaanxi has also taken pains for 40 years. In addition to the implementation of the "four no's" of no hunting, no felling of trees, no use of pesticides, and no cannons in the crested ibis's activity area, it is even more necessary to shut down and transfer polluting enterprises in the protected area, and even major projects such as the Xicheng high-speed railway (Xi'an-Chengdu) have also adopted "giving way" protection measures during the construction process. It is this kind of caution that allows the crested ibises to thrive in nature.
The crested ibis is an autumn social animal, meaning that in the autumn they choose to rest together. The sight of a bird's overnight stay like this can only be seen in this season, but the crested ibises have extremely high requirements for the standard of overnight accommodation, and need to meet three key words, that is, good mountains and good water and quiet, in order to create a suitable overnight place for them, the locals have made a lot of efforts and efforts for decades. Along the foothill road, from time to time, you can see warning signs reminding pedestrians to pay attention to protection, and the villagers who live in the surrounding area are also information officers, recording the every move of the crested ibises who stay overnight.
In addition, generations of conservation workers have carried out "manual monitoring" of crested ibises in the wild through naked-eye observation and other means, and have not slackened off for 40 years.
