South America is the region with the highest rate of conversion of forest land to other uses. It has lost an average of 7 million hectares in recent years.
Reforestation decreases global warming . When the carbon dioxide in the atmosphere increases, the temperature of the Earth increases. Trees trap carbon dioxide.
Trees are thermal insulation, reduce the effects of wind and pollution particles in the air that can cause harm to people´s health. Also they absorb CO2 and produce oxygen.
Reforestation preserves biodiversity and the natural habitat. It provides shelter for wildlife and home to abundant native flora, many of which are in serious danger of conservation.
Trees prevent soil erosion and being dragged to other locations. The roots hold the soil; branches, leaves and trunk damp the wind and raindrops.
Human activity generates six gigatonnes of carbon dioxide a year; however, the Earth can only recycle three. The rest of it is accumulated each year in the atmosphere, intensifying the greenhouse effect.
Know the planting process step by step: since the method is planned according to the conditions of each site to the monitoring that allows us to evaluate the growth of each area already planted.
Together with CONAF, we collect information of the areas and we select the plantation sites as well as the species to be planted. The planting method is planned according to the site conditions, soil requirements and climate. Reforestation takes place twice a year: in the periods between April-May and from August to October.
Plants grow in a ship of acclimatization where the necessary nutrients for their development are applied. When they have reached optimal conditions for field survival (one year approx.), they are packed for transportation. Each plant has a special gel that keeps moisture of the root since the plants leave the nursery until they are established in the field.
The plants leave the nursery towards the reforestation areas in trucks that have the capacity to carry up to 30,000 plants. When the areas are inaccessible, the plants are carried in vans, horses and oxen.
The leader of the planting team delivers the daily number of trees to be planted. The reforestation area set in advance is labeled with the proposed planting design.
The plantations are carried out as a restoration process. This system is different from planting in rows as it pretends to assimilate as much as possible the natural development of the forest. The plants are distributed in areas of 100 m², reaching about 2,000 plants per hectare.
The plants should be protected from herbivores, primarily hare, rodents and guanacos. The main kind of protections used are the perimeter fences (woven hexagonal mesh) and individual plant protectors.
Once a year the ignition and the current status of the plants are evaluated so as to know how much they have grown and what percentage of them have been attacked by hares and other herbivores. Finally, the plants that did not survive are replaced, and the fences are repaired as well as individual protections are changed
