The central urban area of Shenzhen reproduces wild water fern!The reporter exclusively interviewed the scientific research team to restore the entire process of wild water fern

At 9 o'clock one day in May this year, Bushishan Park, Futian District ushered in a day of festive time. "Hurry up, wild water fern appeared again, come to our Bijia Mountain Park!" Lin Shishi, head of the Biological Diversity Investigation Team of Guangdong Environmental Protection Engineering Vocational College of Environmental Protection Engineering, conducted a biodiversity survey as usual, and was suddenly attracted by several plants. Stopped. He followed the stream, carefully picked up the wetland herbaceous plants on the upper layer, pulled away the stones, and several wild water fern exposed in the stream stones.

This is a scene where the wild water fern group appeared again in Shenzhen. Recently, the Municipal Ecological and Environment Bureau found in the city's biological diversity survey that 8 wild water fern appeared in Bijiashan Park. Rare, with important biological protection, scientific research and popular science value, reflects the effectiveness of the biodiversity of urban biological diversity symbiotic and harmoniously symbiotic in Shenzhen.

"After a lapse of 5 years, we found wild water fern in the Bijiashan Park again, which is reasonable and reasonable." Lin Shishi was an expert who found the wild water fern. As early as 2017, he and the Biological Diversity Investigation Team of the Guangdong Environmental Protection Engineering Vocational College of Environmental Protection Engineering found two wild water fern for the first time in Bijiashan Park.

Recently, Shenzhen once again found that the specific time of wild water fern was one morning at the end of May this year. On the same day, he and two investigators saw it around Shuangyao Lake in Bijia Mountain Park that wild water fern was distributed along the small stream and grew on the water. Some are hidden in the gap in stream stones, and the other grows in wetlands.

"1, 2, 3, 4 ... We just counted at the beginning, there were 4 plants, so beautiful!" Lin Shishi said. He specially brought underwater photography equipment and took pictures of wild water fern. The water fern is soaked in the water, half extends in the air, accompanied by a faint green grass flavor, which is very happy.

Out of the consideration of protection and further investigation, the news has not been announced before. After more than two months of investigation, Lin Shishi finally found 8 wild water fern in the grass of nearly 50 square meters. The family of water fern is a native wild population.

This is 5 years later, Bijiashan Park is recorded again to wild water fern. "Wild water fern lost in Bijia Mountain Park, and we felt very happy." Lin Shishi said that in the past two months, they went to seven or eight times before and after. Just the day before yesterday, they were also ready to go, went straight to the "scene of the crime", and observed the growth of water fern again. Lin Shishi told the deep evening reporter that the water fern population grows healthy population in the Bijia Mountain Park, showing that it has an excellent ecological environment in the urban area of ​​Futian.

Bijiashan Park has strengthened local protection measures

On the afternoon of July 26, the reporter saw at the Bijiashan Park at the scene that the wild water fern grew "stubbornly" in a lawn that exuded from the stream. It snuggled the stones around him, quietly leaned out, stretching his torso towards the sky, and his vitality. The whole plant of the water fern is emerald green, which is obviously shallow than other green plants. The leaves are rounded and rounded, and it extends to the ground in the shape of Portuguese. The maximum length is about 32 cm.

As the trickle water flows down, not far away, the breeze blows, the tree shadow is mottled, as if entering a hidden natural world. Late evening reporters saw 8 wild water fern along the stream. They were accompanied by the ferns around them. The clear supply of clear spring water continued to provide a suitable living environment for water fern.

The reporter saw at the scene at the scene that the Bijiashan Park Management Office had strengthened local protection measures to surround the water -fern area along the park stream, set up safety protection signs, notice signs, prevent and control foreign invasion, and strengthened on -site patrols on the spot. Protect.

The appearance of wild water fern reflects the ecological environment of Shenzhen's good development to a certain extent. On July 26, the reporter learned from the Shenzhen Ecological and Environment Bureau that in fact, in November last year, Shenzhen Maozhou River opened a new round of "production, life, ecological integration" Bi Dao pilot construction, and was surprised to discover the Maozhou River. A wild water fern grows next to Bi Dao Bi Dao. This discovery was that after the foundation of wild water fern in the Guangming section of the Maozhou River in the past two years, the foundation of wild water fern groups in the central urban area of ​​Shenzhen, which fully reflects the effectiveness of the biological diversity of cities that are symbiotic in harmony between Shenzhen people and nature.

At present, the Municipal Ecological and Environment Bureau, together with the Municipal Planning and Natural Resources Bureau, the Municipal Urban Management and Comprehensive Law Enforcement Bureau, and the relevant departments of the Futian District Government, organize experts to investigate and evaluate on site, and find that the future growth environment of the water fern population faces multiple tests. Relevant departments are actively discussing protection measures to create safe and reliable habitats for them. They also hope that citizens can take good care of them.

Lin Shishi also revealed to a late night reporter that the relevant scientific research team is planning to further promote the ecological repair project. Combined with rich species resources such as fireflies, dragonflies, butterflies, and frogs in the areaThe landscape, and expects through this "umbrella", with the construction of the urban ecological corridor, gradually allows the characteristic native animals and plants such as water fern to naturally expand from Bijia Mountain to Futian River, Shenzhen Central Park, and Shenzhen River.Ecological parks form a "ring of water fern" to better protect Shenzhen's various native animals and plants.Know Duo D

In the "National Key Protection Wild Plants List" re -revised in 1999 and 2021, they were all listed as national second -level key protection plants and were included in the "Red List of Endangered Species of the World Nature Protection Alliance" (Vu) Species.Water fern is very sensitive to the living environment and is considered a "indicator" of the ecological environment.
