Exploitation of forests in a sustainable way

Expanding forest areas by promoting regeneration of trees, allowing their growth as higher use of methods that reduce crop losses and the establishment of conservation areas within the forests for the production can increase long-term average quantity of carbon stored. These management options can also have positive effects on biodiversity and other key ecosystems, such as maintenance of hydrological flows.

Allowing trees to grow more before being cut contribute to the structural diversity of forests and provide a habitat for a wider range of species. Healthy forests that retain the complexity and diversity of natural age structure and habitat, are usually more stability and strength to cope with disorders associated with climate change.

Trees grow quickly when young, but growth slows as they reach maturity. To increase storage capacity of carbon over time, cuts should be made after the annual growth rate falls below the average rate of growth. But as companies producing wood have strong economic interests to make cuts when prices are most favorable, many forests are cut long before the optimal age. Increasing the time interval between cuts or maintain older trees over a period of several successive cycles of cutting could lead to a significant increase in carbon stocks. Band damage trees and soil during the period of travel trunks cut may also lead to a reduction in CO2 emissions.
How do you think that the afforestation proces should be improved?
