Significant impacts of activities, products, and services on biodiversity

Management of Environmental Aspects and Impacts (GAIA) defines the model for identifying and assessing environmental aspects and impacts of Suzano’s products, activities, and services in Forestry Units.
The environmental aspects and impacts of the forest productive areas are identified and recorded in a Matrix for Identification and Evaluation of Environmental Aspects and Impacts (AIA Matrix), for each forestry unit. The methodology is corporately validated and, based on this, the impacts that have been classified as significant define control measures to avoid, reduce, and mitigate the effects.
The direct and indirect environmental impacts identified and classified as significant on biodiversity may involve changes to the physical quality of the soil, the possibility of contamination and changes to the quality of the soil, changes to wildlife, scarcity of water resources, and silting of watercourses, contamination, and changes to air quality. In all these cases, control measures are implemented to avoid or mitigate the effects, so that they do not occur and do not harm the environmental quality. Besides these, there is a significant positive impact related to the reduction of the greenhouse effect, due to the carbon sequestration performed by the planted and native forests.
Although not classified as a significant impact, the invasion of alien species located in the company’s conservation areas was mapped and has an impact on local biodiversity, since it can delay or prevent the development of natural regeneration in some areas. Examples of identified invasive alien species are: Pinus sp.; Acacia (mainly Acacia mangium and A. auriculiformis); sabiá (Mimosa caesalpiniifolia), oil palm (Elaeis guineensis), river tamarind (Leucaena leucocephala) and other species, to a lesser extent.
Under the Environmental Impacts Assessment methodology, the teams responsible have defined control measures to avoid or mitigate all environmental impacts classified as significant in forestry processes.
In addition, Suzano conducts periodic monitoring to evaluate the perpetuity of the biodiversity in all of the company’s units, where sampling points are strategically established to make these studies. Biodiversity (wildlife and flora) has been monitored since 2008 in Bahia and Mato Grosso do Sul, 2009 in São Paulo, 2012 using a new methodology in Espírito Santo and Minas Gerais, and since 2013 in Maranhão.
