From 2016 to 2020, Hanoi planted more than 1.6 million trees, many of which appeared on the streets of the capital for the first time.
On March 5, Hanoi city announced the replacement of maple trees on Nguyen Chi Thanh – Tran Duy Hung street due to underdeveloped and dry dead trees. This is the type of tree planted at the beginning of 2018 and is part of the city’s one million green trees planting program in the 2016-2020 period (the program).
Dr. Dang Van Ha, Director of Landscape Architecture and Urban Greenery (Forestry University), said that since the first maple trees were planted on the street, he considered this tree not suitable for the land. , the northern climate. However, according to Dr. Ha, 262 maple trees to be replaced this time are only a small number in the overall program of planting one million new trees in Hanoi.
“Looking back now, I think this is a breakthrough initiative for urban greenery development not only in the capital but also in the whole country,” said Mr. Ha.
Citing that many streets of Hanoi today have “brought a green color” different from before, such as Lang, Hoang Dieu, Vo Chi Cong, Van Cao, Hoang Quoc Viet …, Dr. Ha said that the success of The program is an objective fact that any citizen or visitor to the capital “feels the beauty of the trees and its value to the environment”.
The uniqueness of the green tree development program in the capital is in the organization of summer renovation, median strips to create strips of flowers, multi-layered, canopy (plants, flowers in four seasons). For example, Vo Nguyen Giap street connecting Noi Bai airport with the central area has a wide median strip, covered with five floors of trees.
According to Dr. Ha, in the context that the Prime Minister has just approved the project of planting one billion trees to build green trees (690 million trees in urban areas, in rural areas, 310 million trees in forests), then looking back at the program of planting one million new trees of The capital is “very meaningful, can be learned useful lessons”.
The program to plant one million new trees in Hanoi was started at the end of 2015. To realize the goals, the city has asked the Green Tree Company to send delegations to visit to learn about planting, tending and maintaining trees in China and Singapore. At that time, many new plants were planted on the streets of the capital such as purple phoenix, small leaf eagle, date, maple …
Many provinces and cities in the country, some international organizations and enterprises also donated trees to the capital such as Dien Bien, Son La to give white flowers; Vietnam-Japan Friendship Association presents cherry blossoms …
By the end of 2018, Hanoi announced the completion of planting one million new trees, and set a target to plant an additional 600,000 trees by 2020. Generally, in the period 2016 – 2020, Hanoi reported “planted more than 1, 6 million trees, including urban trees, shade trees, trees of all kinds “. In particular, the city planted more than one million trees, the districts planted over 539,000 trees and more than 73,000 trees under the socialization.
“The new planting increases 40-50 times in the previous period and creates green strips, green spaces, green corridors to help regulate the air, increase humidity, limit noise, and limit air pollution. “, the city report stated.
Hanoi also affirmed that “the quality of plants is guaranteed, regularly cared for and pruned according to the correct process”.
However, the city recognizes that the program has some limitations such as: Variety of trees is not abundant; Some crops have not been thoroughly tested, so they are not suitable for climatic and soil conditions.
Dr. Dang Van Ha also said that, in addition to success, the program “reveals a number of problems in the selection of tree species, tree standards and maintenance management”.
According to him, before carrying out the program, the city should make a plan and choose trees suitable for different types of urban green spaces. “Because there is no prior planning, the pressure in a short time to plant a million new trees makes it difficult for the city to find trees and supplies,” he said.
“Perhaps to overcome that situation, the city has massively planted many new species of trees in many streets such as phoenix, small leaf eagle, date …”, Dr. Ha added. Some types of city trees are known as “experimental planting, but in other countries no one has brought them out for street trials”. According to Mr. Ha, the testing of tree species must be conducted in nurseries with similar climatic and soil conditions and, if appropriate, put on the street.
Mr. Ha also said that, in the program, some large-diameter trees have been planted, this approach is no longer suitable in developed countries because of high cost and low safety. Hanoi should have specific regulations on the size of trees and trees in urban areas must have branches and canopy in order to create an immediate landscape.
“For big cities like Hanoi or Ho Chi Minh City, there should be an independent specialized agency on construction supervision, maintenance of trees, not just a department or department in the construction industry as today” , Dr. Ha proposed.
Before implementing the program to plant one million new trees, in August 2013, Hanoi issued a plan to invest in the development of a system of green trees, parks, flower gardens and lakes for the period up to 2015. According to the plan. This 6,700 trees will be cut down and replaced. The project was implemented in a number of streets of Hue, Hang Bai, Kim Ma, Giang Vo … with socialized capital. However, when 381 trees on Nguyen Chi Thanh street were cut down in March 2015, public opinion reacted strongly.
The inspection results later showed that the implementation of the plan had many shortcomings, causing some collectives and individuals to be disciplined with different forms.
