On April 15th, the Davidia involucrata (also known as the dove tree or handkerchief tree), a wild plant under first-class national protection, quietly bloomed in the Lvluo Botanical Garden in the central urban area of Yichang. Its pure white bracts fluttered gently in the wind like white doves perched on branches, creating a precious ecological spectacle within the city.
The Davidia involucrata is a typical alpine rare plant. As an ancient relict species from the Tertiary period, it is hailed as a “living fossil of plants” and the “giant panda of the plant kingdom.” It has stringent requirements for its growing environment, naturally distributed in deep mountain forests at altitudes of 1,500 to 2,200 meters. It is exceptionally rare for this alpine flower to successfully bloom in the urban area of Yichang.
It is reported that this flowering Davidia involucrata was introduced by the Yichang Landscape and Plant Research Institute in 2019 from Changyang. After years of systematic cultivation by researchers, who employed scientific introduction and adaptive domestication techniques, the challenge of adapting it to a low-altitude environment was successfully overcome, allowing the tree to grow stably and bloom successfully in the urban setting.
This achievement marks a significant breakthrough for the institute in the fields of ex-situ conservation and the introduction and domestication of rare plants. It also highlights the continuous optimization of Yichang’s urban ecological environment and the notable effectiveness of its biodiversity conservation efforts. The head of the plant research institute stated that they will continue to introduce excellent plant varieties to enrich the urban landscape, allowing residents to enjoy more “green benefits” right at their doorstep.
Davidia involucrata
“Davidia involucrata,” commonly known as the dove tree or handkerchief tree, is a rare and ornamental tree species native to central and southwestern China. It was first described for Western science in 1869 by French missionary and botanist Père David, after whom it is named, and later introduced to Europe by plant collector Ernest Wilson in the early 20th century. It is celebrated for its distinctive large, white bracts that resemble fluttering doves or handkerchiefs when in bloom during spring.
Lvluo Botanical Garden
Lvluo Botanical Garden is a modern botanical garden located in Shenzhen, China, established in 2007. It is designed to showcase plant conservation and biodiversity, featuring themed sections like the Primeval Forest Ravine and the Cactus & Succulent Garden. The garden serves as a key center for scientific research, public education, and ecological recreation in southern China.
Yichang
Yichang is a major city in China’s Hubei Province, historically significant as the gateway to the scenic Three Gorges on the Yangtze River. Its modern identity is profoundly shaped by the nearby Three Gorges Dam, the world’s largest hydroelectric power station, completed in the early 21st century after decades of planning and construction. The city has long been a strategic transportation hub and is also known as the hometown of the ancient poet Qu Yuan.
Tertiary period
The Tertiary period is not a specific place or cultural site, but a former geological time unit in Earth’s history, spanning from about 66 million to 2.6 million years ago. It followed the extinction of the dinosaurs and witnessed the rise of mammals, birds, and modern plants. The term “Tertiary” is now considered informal in geology, having been largely replaced by the Paleogene and Neogene periods in the official timescale.
Changyang
Changyang refers to Changyang Tujia Autonomous County in Hubei Province, China, an area historically inhabited by the Tujia ethnic minority. It is renowned for its rich cultural heritage and significant paleoanthropological discoveries, including the “Changyang Man” fossils dating back approximately 195,000 years. Today, it preserves traditional Tujia customs and serves as an important site for understanding early human activity in southern China.
Yichang Landscape and Plant Research Institute
The Yichang Landscape and Plant Research Institute is a botanical garden and research center located in Yichang, Hubei Province, China, near the Three Gorges Dam. It was established to study, conserve, and display the diverse plant life native to the region, particularly species from the Three Gorges area. Its work plays a key role in ecological preservation and public education following the massive environmental changes brought by the dam’s construction.
ex-situ conservation
“Ex-situ conservation” refers to the practice of protecting endangered species, varieties, or cultural artifacts by removing them from their natural or original habitat and preserving them in a controlled, off-site setting. Common examples include zoos, botanical gardens, seed banks, and museums, which safeguard biological diversity or cultural heritage that is under threat in its native environment. This method has become a crucial complement to in-situ (on-site) conservation, especially for species or artifacts facing immediate extinction or destruction.
biodiversity conservation
Biodiversity conservation is the global effort to protect the variety of life on Earth, including species, ecosystems, and genetic diversity. Its history is rooted in the 20th-century recognition of accelerating extinction rates, leading to international agreements like the 1992 Convention on Biological Diversity. Today, it involves strategies from establishing protected areas to promoting sustainable practices that balance human needs with ecological health.
