The reduction of the world's forests threatens a global ecological catastrophe. The contribution of forests and phytoplankton of the seas and oceans in the processes of photosynthesis, responsible for maintaining oxygen in the Earth's atmosphere, is divided equally at a ratio of forest and water surface areas of 9:71. The protection and restoration of lost forests, in Russia coniferous forests, is a paramount task. The problem of forest restoration is being solved at the government level. Decree of the Government of the Russian Federation dated 21.09.2020 No. 1509 «On the peculiarities of the use, protection, protection, reproduction of forests ...». The effect of plasma-activated water (PAW) on the stimulation of seed germination, the development of conifers in the early stages of their growth was studied. PAW was obtained using UHF plasmotron generating plasma in the atmosphere. PAW contains solutions of hydrogen peroxide and nitrogen oxides, which are necessary for plant life. VAP solutions were tested by the concentration of hydrogen peroxide. The initial concentration of hydrogen peroxide was 8·10-3 M. The seeds of fir and larch were germinated on filters moistened with water in the control, in the experiment with VAP solutions. The most effective VAP solution was a solution with a hydrogen peroxide concentration of 2·10-6 M, which provided an increase in the germination of larch and fir seeds by 25 and 30%, respectively, compared with the control. The germinated seeds were placed in transparent culture vessels on sand, which was moistened once with water in the control, in the experiment with VAP solutions. The vessels were closed. Seedlings were grown in stressful isolation conditions. We tested the development remotely. By the 30th day, 5% of the seedlings survived in the control and 40-45% of the seedlings survived in the experiment.
