The age that a forest reaches depends on many reasons, and one of them is the degree of its renewal. There is natural, combined and artificial forest restoration. Foresters help the "green sea" not disappear and bring great benefits to all people on the planet.
Instructions
Step 1
Natural regeneration of the forest takes place without human intervention. Artificial occurs when foresters plant trees and other plants in areas of clearings and fires. The combined one combines natural processes and caring human intervention (forest protection, care).
Step 2
Reforestation is carried out using seeds or vegetatively. Birches, oaks, maples, beeches reproduce by overgrowth from stumps and seeds. Aspen, poplar, alder, euonymus, hawthorn are spread by root shoots and seeds. Conifers reproduce only by seeds.
Step 3
Foresters attach great importance to the effective use of the power of nature in reforestation. Special systems for cutting and preserving undergrowth are used, which ensure the resumption of plantings. Valuable tree species: cedar, oak, spruce, pine and many others are planted with young growth.
Step 4
Logging in Russia is simply huge, and accordingly, thousands of tons of seeds of spruce, pine, larch, oak, birch, elm and cedar are needed to restore them. Only the best trees are suitable for harvesting and subsequent planting, with a good trunk shape, crown and wood quality. Not all seeds germinate and grow into large, full-grown trees.
Step 5
Saplings are also grown in greenhouses, where they germinate twice as fast. Seedlings grow very well and quickly in a greenhouse, but it is economically profitable to grow only annual seedlings there. Plants propagate there vegetatively, in small twigs.
Step 6
There are also whole forest nurseries where planting material is grown for reforestation. They are laid on flat areas not far from the future landing.
Step 7
Foresters daily take care of plantings, mature trees and natural thickets of bird cherry, viburnum, wild rose and mountain ash. Care consists in lightening, cleaning, removing diseased and damaged plants. The best conditions for growth and development are created.
Step 8
Schoolchildren, students, and ordinary citizens can help reforestation by sowing and planting trees and shrubs in uncultivated and empty areas. Public organizations carry out work on the improvement of thickets and lay new forests, groves and oak groves.
