Sustainable wood production management has become a significant concern worldwide, particularly in the tropics, where bioclimatic conditions reach high potential productivity. Planted forests play a central role in different elements cycles (for example, in carbon) and the water cycle, cooling the earth's surface temperature, regularizing earth energy, and biodiversity preservation (Ellison et al. 2017).
Brazil is a leader in wood-based products from planted forests worldwide. Planted forests for industrial purposes reached 7.84 million hectares of the national area in 2016 (Martins et al. 2020), compared to 485 million hectares of natural forest (Oliveira et al. 2020). In 2019, the total area of planted forests was 9.0 million hectares, a 2.4% increase over 2018 (8.79 million hectares) (Oliveira et al. 2020). The majority of the planted forests (77%) represented by introduced species in Brazilian ecosystems : eucalyptus plantation, with 6.97 million hectares and 18% pine forests, with 1.64 million hectares. Besides these planted forests, there are an additional 0.39 million hectares planted with other species, including rubber, acacia, teak, and paricá (IBA 2020). Thus, the planted forest is a good option for the increasing demand for wood in Brazil (Martins et al. 2020) and can reach 90% of the wood produced by the Brazilian industrie (Oliveira et al., 2020).
On the other hand, several studies present alarming data on climate change on dynamic and forest structure, like biodiversity loss, impact on providing ecosystem services increasing fire risk, drought, and non-native plant invasion (Foster 2001; Rodrigues et al. 2015; Scarano and Ceotto 2015; Martins et al. 2020; Cui et al. 2021). However, climate change presents a significant challenge for the current economic model with a high population growth rate and intense natural resources pressing (Medeiros et al., 2020).This challenge becomes more involved in economic activities dependent on climate conditions like planted forests, and the role that planted forests can play in the future the mitigate the effect of climate change (Choi et al. 2021).
Species distribution modeling (SDM) is a useful technique that can overcome the difficulties related to complexity of studying the interaction between plant species behavior and climate changes. Furthermore, this modeling allows predicting species geographical distribution from the occurrences data and bioclimatic variables (Lobo et al. 2010). It can help the governments plan policies for mitigation of the climate change impact thought a plantation of forest species adapted to a specific region.
SDM is a predictive species distribution based on applying mathematical and geostatistical methods to environmental variables to fit predictive habitat distribution modeling and map the species distribution in the space and in the time. SDM has achieved different ecology and conservation sciences applications related to the planted forest (Cayuela et al. 2009). These applications include predicting potential planting areas (Martins et al. 2020), identifying the extent and direction of range shift of forest species (Shabani and Kumar 2017), assessing the impact of climate change, and supporting conservation planning and reserve selection.
Throughout its large extension, Atlantic Forest has marked by high rate of degradation, which has increased the demand for adapted forest species mainly that can generate income-associating conservation with economic return, to adopt the rural properties that are located there legally.
Apuleia leiocarpa (Vogel) J. F. Macbr. is a native monoic species of the Brazilian Atlantic Forest domain (Lauterjung et al. 2019), and it is widely recognized due to the high quality of the wood, beekeeping, medicinal, landscape, and forestry potential of this species. The A. leiocarpa has a significant environmental and industrial role because it is used in wood products and the reforestation of degraded areas. Its distribution extends to different South American countries: Brazil, Argentina, Uruguay, Bolivia, and Paraguay (Zimmerman et al. 2013). Currently, the occurrence of A. leiocarpa in Brazilian territory is discontinuous because of the high rate of deforestation and the lack of replanting and being classified, as to the risk of extinction, as a vulnerable species (Salemi et al. 2013). In this sense, correlations between attributes of soils and A. leiocarpa matrices can be useful tools in checking restrictions on their natural distribution, as well as in the management of species in commercial plantations or seed orchards.
In view of the growing importance of the supply of wood from native forests, the identification of potential habitats for planting trees can provide great opportunities for the conservation and management of natural forests. This justifies the creation of specific governmental policies to encourage legal production of native forest species in order to mitigate the impacts of natural forest exploitation (Martins et al. 2020).
In this context, this study aims to estimate the potential distribution and the impact of climate change on the future distribution of A. leiocarpa in Rio de Janeiro and Minas Gerais, Brazil. Here, we addressed the following questions: (a) how is the A. leiocarpa distribution pattern in Rio de Janeiro and Minas Gerais states ? (b) Do climate conditions and soil variables congruent predict the patterns of species distribution? Finally, we discuss conservation issues based on the obtained results.
