“…Oliveira et al (2020) The unknown specimens were identified by common names and had vegetative material collected to determine the scientific names from a comparison made at the IAN Herbariums of Embrapa Amazônia Oriental and the Emílio Goeldi Museum. The botanical classification system used was "Angiosperm Phylogeny Group" (APG III, 2009), and the botanical nomenclature conferred with the electronic database made available by the Missouri Botanical Garden (MOBOT, 2016).…”

“…The sustainability of forest management is not compromised if the cutting intensity does not exceed the capacity to recover the remaining stock in a given planned time (REIS et al, 2018). According to Nascimento et al (2014), decision-making in forest management requires precise growth and production forecasts in different scenarios capable of providing various possibilities for logging.…”

Research is needed to subsidize foresters to manage the forest for better use of wood. To help in the research, analyzing the diameter distribution, the species can be grouped according to their characteristics concerning the diameter growth and projected their future growth, determining if they reached the expected diameter before the cutting cycle stipulated by law. The aim of the present research was to diametric distribution predict by a size class distribution method, by ecological groups. The study was carried out in Moju, PA. Nine clearings were selected, around which 4 sample plots of 10 x 50 m were installed, starting at the border of the clearing into the forest in the north, south, east and west directions. All individuals with DBH (diameter at breast height) ≥ 5 cm were measured. The species were grouped into tolerant, intermediate and intolerant regarding the demand for solar radiation. The methods tested were Transition Matrix and Moving Ratio, using data from 1998 and 2001 and making projections for 3 year periods (2007 and 2010). The efficiency of the projections was tested using the Kolgomorov-Smirnov adhesion test. The projections performed by the methods did not present a significant difference between the actual and projected values. Based on the results it is recommended to use the Transition Matrix for the prognosis of the diametrical distribution of individuals belonging to the group of tolerant and intermediate species and it is indicated to use both methods for intolerant species.

“…Penelitian tentang model pertumbuhan baik model pertumbuhan per pohon, model kelas tegakan dan model seluruh tegakan (Hevia, Cao, Álvarez-González, Ruiz-González, & von Gadow, 2015;Turland, 2007) telah banyak dilakukan dengan menggunakan model matriks (Adame, Brandeis, & Uriarte, 2014;Krisnawati et al, 2008;Leoni et al, 2011;Nascimento, do Amaral Machado, Figueiredo Filho, & Higuchi, 2014;Návar, 2014;Orellana, Figueiredo Filho, Netto, & Vanclay, 2016;Picard & Liang, 2014;Pukkala et al, 2009;Pütz, Groeneveld, Alves, Metzger, & Huth, 2011;Roitman & Vanclay, 2015;Venturoli et al, 2015;Wang et al, 2009).

ABSTRAKPengelolaan hutan berkelanjutan sangat membutuhkaninformasi pertumbuhan yang mengintegrasikan fungsifungsi ingrowth, upgrowth, dan mortality. Penelitian dilakukan pada areal Ijin Usaha Pemanfaatan Hasil hutan Kayu (IUPHHK) PT. Tunas Timber Lestari (TTL), PT. Wapoga Mutiara Timber (WMT) dan PT. Manokwari Mandiri Lestari (MML) di Papua. Tujuan dari penelitian ini adalah untuk menghasilkan model pertumbuhan tegakan untuk hutan alam bekas tebangan berdasarkan data petak ukur permanen di Papua. Model Hasil penelitian menunjukkan bahwa karakteristik tegakan (luas bidang dasar, jumlah pohon dan ukuran/diameter pohon) berpengaruh berbeda terhadap model ingrowth, upgrowth, dan mortalitytegakan pada masing-masing lokasi. Pada PT WMT karakterisitik tegakan berpengaruh nyata terhadap model ingrowth, upgrowth, dan mortality yang ditunjukan dengan nilai koefisien determinasi yang tinggi >80% dan Pval<0,05, walaupun pengaruh karakterisik tegakan tidak secara bersamaan berlaku pada setiap model. Pada PT MML yang berpengaruh nyata hanya model ingrowth dan upgrowth, sedangkan pada PT. TTL hanya model ingrowth. Kata kunci: model seluruh tegakan, model linier, hutan bekas tebangan, Papua

“…A modelagem do crescimento e da produção visa contribuir com as atividades do manejo, uma vez que tem o poder de prever o momento em que a floresta recupera seu estoque após a exploração florestal. Segundo Nascimento et al (2014), a tomada de decisão na gestão das florestas exige previsões precisas de crescimento e produção em diferentes cenários capazes de fornecer várias possibilidades para a exploração madeireira.…”

O trabalho teve como objetivo realizar a prognose da distribuição diamétrica da floresta utilizando o modelo Matriz de Transição para as espécies classificadas como tolerantes, intolerantes e intermediárias e definir o ciclo de corte por grupos ecológicos, a fim de verificar se o tempo definido na legislação ambiental brasileira é compatível com a recuperação e crescimento das espécies arbóreas. A área da pesquisa localiza-se em Moju, Pará-Brasil. Selecionou-se 9 clareiras, em torno das quais instalou-se 4 parcelas amostrais de 500 m². Foram medidos todos os indivíduos com DAP ≥ 5 cm. Para a prognose, utilizou-se os dados reais dos anos 2007 e 2010 e fez-se as projeções para períodos de 3 anos (2013 a 2028). Com os dados prognosticados fez-se a estimativa do volume até 31 anos após exploração florestal. Constatou-se que para as espécies tolerantes e intolerantes o ciclo de corte ideal é de 16 anos e para as intermediárias é de 22 anos.
