In the sky, amidst the waves, in the cold desert, in the deep valleys of the jungle, there are countless beautiful creatures. Many people silently watch and carefully care for them, allowing them to live freely and interpreting the magnificence of life with a unique posture. As one of the earliest countries to sign and ratify the Convention on Biological Diversity, China attaches great importance to biodiversity conservation and integrates it into the entire process of ecological civilization construction. Protecting biodiversity is also closely related to the lives of each and every one of us. Let's learn about the latest progress in biological conservation work through the stories of four endangered species cultivation and protection. The Years of Flying with Crested Ibis Teller: Zhang Yueming, Senior Engineer of the Hanzhong Crested Ibis National Nature Reserve Management Bureau in Shaanxi Province. In Yang County, Hanzhong City, Shaanxi Province, the graceful dance of Crested Ibis can be seen everywhere. I have been joining the Crested Ibis Conservation Team for over 30 years. Over the years, due to the companionship of crested ibises, they have also become unique. Previously, due to the reduction of wetlands and the extensive use of pesticides and fertilizers, the living environment of Crested Ibis rapidly deteriorated. After years of arduous search, in 1981, the only seven wild crested ibises remaining in the world were finally rediscovered in Yang County, Hanzhong, Shaanxi. In order to protect this endangered species, the country has established a professional protection agency in Yang County. In 1989, I was honored to join this team. At that time, the number of Crested Ibis hovered around 10 and could become extinct at any time. Work begins with mountain patrols. On the second day after reporting, I arrived at the Sancha River station on the high mountain, 30 miles away from the county town, and began a survey on the number of Crested Ibis. The observation point of the Sanchahe Crested Ibis is very remote, surrounded by dense mountains and forests, and well arranged paddy fields. I think the Crested Ibis stays here because this pure land is like a paradise. For most of the month, I saw four or five crested ibises. At that time, there were very few people who could see so many Crested Ibis, and I was very excited. In November of that year, workers at Baohe Railway Station in Hanzhong also discovered a crested ibis in the local area. The unit immediately sent us to track and monitor it, which lasted for six months. I ride my bike every day, leaving early and returning late to monitor that crested ibis. In May 1990, I was transferred again to support the Yaojiagou observation point. During the day, I sat in the observation shed, carefully observing the every move of the Crested Ibis, analyzing its ecological habits. At night, I arranged for villagers to be on duty under the Crested Ibis nest tree to prevent natural enemies from climbing trees and endangering the breeding of Crested Ibis. The first time I saw a baby crested ibis, it was furry and very cute. As it grows and flies, my excitement is indescribable. Around 2000, the population of Crested Ibis developed to 200, including 100 wild Crested Ibis and 100 artificially captive. We finally pulled Crested Ibis back from the brink of extinction. With the increase in the number of crested ibises, it has become difficult to protect them in a human like manner for the past 24 hours. So, we invited community members to join us in protecting. Everyone is very positive. During the breeding season, crested ibis make nests on the nest trees, and the owners of the trees that are used as nests assume the responsibility of guarding them; During the wandering period, we will invite responsible community residents to monitor or take care of the main activity areas and overnight stays of Crested Ibis, and report Crested Ibis information weekly. this
