Abstract(s)
Esta dissertação consiste na elaboração de um plano estratégico para as matas da empresa Pinho & Eucalipto Madeiras, Lda. Inicialmente foi realizado o inventário florestal das propriedades o qual não existia em grande parte delas. Devido a elevada fragmentação das mesmas, sendo a área média de cada propriedade é de 1,26 hectares, algumas propriedades foram agrupadas em povoamentos de maior dimensão para assim ser possível planear as estratégias a longo prazo. Realizou-se uma análise financeira para cada povoamento com o intuito de saber o rendimento líquido de cada um, para se conseguir perceber quais os povoamentos que deveriam ser convertidos para outra espécie florestal, devido ao baixo rendimento com a espécie presente. Recorreu-se a programação linear do software Lingo, para organizar a mata, visto que, depois dos incêndios de 2019 esta ficou muito desorganizada. Depois de organizados os volumes a corte, ao longo dos 48 anos do horizonte de planeamento, foi calculado o rendimento líquido final e a produção total de madeira.
This dissertation consists of the elaboration of a strategic plan for the forests of the company Pinho & Eucalipto Madeiras, Lda. Initially, the forest inventory of the properties was carried out, which did not exist in most of them. Due to their high fragmentation, with the average area of each property being around 1,26 hectares, some properties have been grouped in larger stands in order to be able to plan long-term strategies. A financial analysis was carried out for each stand in order to know the net income of each one, in order to be able to understand which stands should be converted to another forest species, due to the low yield with the present species. Linear programming of the Lingo software was used to organize the forest, since, after the 2019 fires, it became very disorganized. After the cut volumes have been organized, over the 48 years of the planning horizon, was calculated the final net yield and the total production of wood.
