Definitions

  • This invention relates to a eucalyptus forest management platform, particularly directed to Eucalyptus globulus, that provides technical indications for the sustainable management of eucalyptus stands in Portugal mainland supported by geographic information systems.
  • the world forest-based sector has come to increase significantly last years as a result of world population rising, people quality life improvements and market access of a growing share of world population. More specifically, pulp and paper market which is tailored with increases in products demand like sanitary and kitchen absorbent papers, uncoated wood free printing and writing papers, has been pushing the demand for eucalypt wood production whose supply has been done by both pulp companies itself and by market wood independent producers. In Portugal, although the efforts that have been done to improve forest productivity, there is a wood supply gap of roughly 2.5 million m 3 that has been filled by wood importation from Spain, South America and Africa. Recently, the Portuguese government has published a law with some constraints rules including one that limit the expansion of eucalypt plantations.
  • This innovative platform is intended to be user-friendly, considering, among other contents, technical indications of forestry practices that cover the different stages of stands development, such as planting, maintenance and coppicing.
