Briefly discuss the components of a sustainable forestry program and the meaning of FSC certification
What will be an ideal response?
Sustainable forestry implies not only the capacity of a harvesting system to provide timber on a continuing basis but also to conserve the biodiversity and ecosystem services of the harvested forest to the greatest extent possible. The principle of ecosystem-based management includes these goals. Specific strategies would be to remove trees in such a way that the understory suffers minimal damage, to leave enough mature trees to support the biodiversity that depends on them, and to minimize erosion. All aspects of the timber preparation or pulping process (for paper) would need to be energy-efficient and to employ nontoxic biodegradable chemicals at all stages. Effluents from sawmills and papermills should not contribute to eutrophication of receiving lakes or rivers. If all of the steps from tree to marketed product meet the Forest Stewardship Council's standards for sustainable forestry, the companies and products should earn FSC certification.
