In the Tyumen area this year, the reforestation area will amount to almost 7,000 hectares
The second consecutive spring in the Tyumen region is particularly hot in the true sense of the word. This year, since the beginning of the fire season, more than 140 forest fires have already broken out, thousands of hectares of forests have been covered by fires. It was even harder last year. That is why special attention is paid to the issue of the restoration of the “green lungs” of the area. “FederalPress” found out who and how in the Tyumen area deals with the restoration of forests.
Consequences of forest fires
As a result of last year’s fires in the Tyumen region, 369.8 thousand cubic meters of forest were completely burned. In addition, 1,809 hectares of forest crops and young vegetation were lost. This is how the losses in the department of the forest department were assessed.
Since the beginning of the 2022 fire season, 143 forest fires have been recorded in the area. The area covered by the fire is 9,209 hectares. For comparison: in the same period last year, 289 forest fires were recorded and the area covered by fires reached almost 173 thousand acres, ie 18 (!) Times larger than the current scale.
How much the forest has suffered this year remains to be seen. Remember that the area of fire, as well as the area covered by fire, does not mean the death of trees. It is possible to speak objectively about the condition of the plantations only after forest pathological examinations and they take place no earlier than 1-2 months after the fire is extinguished. These are the standards.
This is done by the Federal State Foundation “Roslesozashchita – the center for forest protection of the Tyumen region”. Director Svetlana Timchenko explains that the condition of the trees in the area where the fire has passed is thoroughly assessed. Experts try to prevent unnecessary logging. If the tree has less than three-quarters of its tissue damaged, then there is still a chance for self-healing.
After research, health and leisure activities are carried out – selective and clean logging. Sanitary logging, explains Leonid Ostrumov, director of the forest department, is a necessary measure: dead and damaged trees quickly become a breeding ground for pests that infect a healthy forest and, in addition, such areas are at high risk of future fires.
“If most of the forest cluster died after the fire, then clean cuts are defined. The forest block is then completely removed to ensure the reforestation process in this area. Then artificial reforestation takes place in the prepared soils.says the leader.
This year there will be reforestation and reforestation in 6.94 thousand acres in the area. As for the area, this is the same as Ishim and Zavodoukovsk together. Specifically, artificial plantations will be created on 3.2 thousand hectares. Planting will take place in all 22 forest offices of the area until the beginning of November.
All activities for the reproduction of forests are carried out in the framework of the regional project “Conservation of forests” of the national project “Ecology”.
For planting, coniferous seedlings are used – pine and Siberian fir. They are grown in local forest nurseries. Last year, 20.66 million standard seedlings were prepared for forest planting in 2022. Landing will take about 70% of them. The rest, experts explained to us, will be used in the agricultural care of already established forest plantations with their completion.
Where is the future forest grown?
In total, there are 29 forest nurseries in our area: in 19 of the 22 forestry offices. Every year 1.5 tons of seeds are sown there in an area of 20 acres. Future trees are grown in open fields and greenhouses.
“Such a volume allows the timely supply of high quality planting material and the execution of work related to reforestation”– says Leonid Ostrumov.
The employees of Tyumen air base explain: it takes 2-3 years for the seedlings to grow in standard parameters. During this period, the seedlings are repeatedly uprooted, treated for diseases, cut roots and watered in greenhouses. Most of the time, nurseries use crop rotations of 3 and 4 fields: two fields are sown with seedlings aged one and two years and one or two fields are set-aside, ie the land is rested, but during the season it is cultivated by weeds.
After the seedlings are transferred to permanent places of growth. But it takes decades for a complete forest to grow at the point of fire, of course. Thus, according to the rules of forest management, the pine forest reaches maturity at the age of 80 years, deciduous forests – at the age of 40 years. But already after 10-20 years, the young forest looks mature enough for non-professionals, says the doctor of biological sciences, arborist Stanislav Arefiev.
The scientist says that the pine forests in the subtaiga of the Tyumen region usually recover well on their own:“The least valuable, deciduous species can participate in the composition of a regenerating forest. A forest at the point of fire can grow mixed or even deciduous When you plant a pine forest, you can get a clean pine forest, but it grows in rows, and this is of reduced aesthetic value..
We add that the restoration of forests is not only done by government agencies, but also by tenants of forest plots at their own expense. That says rent. Nearly 262 million rubles have been allocated from the budget for health and leisure activities and reforestation this year, 52.6 million of which are funds from the regional fund.
