Abstract

ABSTRACT The aim of this study was to perform the edaphic-climatic zoning of six eucalyptus species (E. camaldulensis, C. citriodora, E. cloeziana , E. grandis, E. saligna, and E. urophylla) in the state of Rio de Janeiro (RJ). The edaphic-climatic zoning was determined by overlayer of thermal and water (water deficit [DEF] and rainfall), type of soils (pedology), and relief (altitude) suitability maps. Suitability maps were obtained using Geographic Resources Analysis Support System (GRASS-GIS). The species studied showed potential for cultivation in the entire RJ due to different tolerances and requirements to the environmental conditions. The exception was the E. saligna, which proved to be unsuitable for the entire state, while C. citriodora showed the greatest suitability. Among edaphic-climatic factors analyzed, air temperature and DEF were the most important limiting factor for the suitability of species.

Highlights

In Brazil, the forest sector is responsible for approximately 5.5% of the Gross Domestic Product – GDP
In the state of Rio de Janeiro (RJ), for example, the reforested area is only 18,427 ha, which corresponds to 0.42% of the total area of the state and less than 0.1% of the area covered with planted forests in the country (Paula et al, 2012)

Summary

Introduction

In Brazil, the forest sector is responsible for approximately 5.5% of the Gross Domestic Product – GDP. In the state of Rio de Janeiro (RJ), for example, the reforested area is only 18,427 ha, which corresponds to 0.42% of the total area of the state and less than 0.1% of the area covered with planted forests in the country (Paula et al, 2012). Timber production in this area does not meet the domestic demand of RJ, which makes it a large importer of wood for different purposes of the economic sector (Amorim et al, 2012)
