A incorporação de corredores de conectividade em problemas de otimização para o planejamento de florestas industriais

Regulation of even-aged forest with adjacency constraints

“…Applications such as fauna management (Arthaud and Rose, 1996;Haight and Travis, 1997;Bettinger et al, 1997;Kurttila et al, 2002), creation of forest corridors (Moreira, 2008), effects on aquatic systems (Bettinger et al, 1998) and forest transportation systems (Nelson and Brodie, 1990;Weintraub et al, 1995) are examples of problems solved by heuristics. The aim of this paper was not to assess the computational performance of the implemented GA, but rather to evaluate its ability of solving the formulated problem.…”

“…The construction of mathematical models, algorithms and heuristics for the elaboration of management plans of this kind has been a challenge for forest planning in the recent decades (Moreira, 2008).…”

“…These constraints intend to minimize the environmental impacts caused by distortion of the natural habitat, avoiding the cutting of large contiguous areas, and promoting shelter and food to populations living in managed forests. Through this, it is sought to combine conservation and production in forest areas, as well as mitigate the visual impacts caused by harvest activity (Castro, 2007;Moreira, 2008). The incorporation of these constraints can occur in two distinct ways: unit-restriction model (URM) and area-restriction model, (ARM) (Murray, 1999;Murray and Snyder, 2000;Baskent and Jordan, 1995;.…”

Regulation of even-aged forests with inclusion of environmental constraints

“…Adjacency constraints seek to minimize environmental impacts brought about by the destruction of natural habitats, thereby preventing harvest in adjacent or extensive contiguous areas while providing shelter and food to animal populations living in the managed forest and also mitigating the visual impacts caused by harvestrelated activities (CASTRO, 2007;MOREIRA, 2008). Such constraints assume that the management unit will regenerate in less than one year.…”

“…Imposition of green-up constraints occurs whenever the management unit is incapable of regenerating in less than one year BETTINGER, 2000). And the need for the fauna to shift between different fragments of native forest is met by connectivity constraints (MOREIRA, 2008). …”
