Economic analysis and revenue optimization in management regimes of Pinus taeda

Abstract: Economic analysis and revenue optimization in management regimes of Pinus taeda 1The objective of this work was to select, using operational research techniques, management regimes of Pinus taeda L. that maximize the revenue generated by the wood, considering different attractiveness rates. The OpTimber-LP ® software, which performs the simulations using SisPinus ® software, was used for forest optimization. The regimes consisted of different combinations of forest sites, planting densities, thinning regimes a… Show more

“…However, age of application showed to be more important in high-density regimes. It is important to highlight that despite thinnings stimulate the tree diameter to grow in faster rates, oftentimes thinnings should not be applied when a forest is managed aiming to maximize total timber volume, disregarding log diameters, such as addressed by David et al (2017a) and Elesbão and Schneider (2011). In addition, we point out that timber production is associated with soil nutrients, light and water available in medium-and high-quality sites (ACERBI JUNIOR et al, 2002), therefore, we must take into account that the behavior of regimes changes among sites of different qualities (GOMES; MAESTRI; SANQUETTA, 1997;SANQUETTA et al, 1998;DAVID et al, 2017b).…”

“…In addition to the modelling issues, simulating variations of interest rates to assess economically forest investments also contributes, among others, to define thinning regimes, once there is a trend in increasing the number of thinnings, when high interest rates and long rotation forests are considered (DAVID et al, 2017a). As our analysis involves only simulations with three thinnings, we cannot examine the need for thinnings as a response to the variation of interest rates, but in respect of planting density, interest rates had low impact, presenting generally an amplitude of ~500 R$/ha (Table 4).…”

“…A produtividade de um plantio florestal está relacionada com as práticas de manejo aplicadas, com os objetivos de agregar valor, melhorar suas características e obter multiprodutos (KOHLER et al, 2015). Um dos desafios em empreendimentos florestais é o emprego adequado de técnicas de manejo, visando o aumento da produtividade sem que isso aumente demasiadamente os custos envolvidos (DAVID et al, 2017). Dentre essas técnicas destaca-se o desbaste, que leva em consideração quando (período em anos), como (critério de seleção das árvores) e quanto (número de árvores por hectare ou área basal que deve permanecer) (SILVA et al, 2005).…”
