Resumo: | This study aimed to characterize the composition and structure of mopane forest ecosystems, estimating growth rates and determining the diameter distribution. It was used data from permanent plots established in 2002 in Mabalane region, Gaza Province. It was analyzed the species composition . It was also determined the horizontal structure of the forest (abundance, dominance, frequency and importance value index) and the annual periodic increment in diameter. The results showed that 15 tree species belonging to eleven botanical families occur in this region. The forest is dominated by Colophospermum mopane (Benth.) J. Léonard (mopane), with an abundance of 258.80 trees per hectare, which represents 85.8% of all individuals. The periodic annual increment in diameter observed in the period from 2003 to 2010 was 1.19 mm year-1, withdiameter distribution as inverted J-curve. Mopane forest shows slow growth and low species diversity, so it is important to apply silvicultural interventions and to establish a management plan taking into consideration the species growth rate and horizontal and vertical structure of the forest. |

Foram usados dados de parcelas permanentes estabelecidas em 2002 na região de Mabalane, Província de Gaza. Foi analisada a composição das espécies, sendo determinada a estrutura horizontal da floresta (abundância, dominância, frequência e índice de valor de importância) e e o incremento periódico anual em diâmetro. Os resultados mostraram a ocorrência de 15 espécies arbóreas pertencentes a onze famílias botânicas. A floresta é dominada pela espécie Colophospermum mopane (Benth.) J. Léonard (mopane), com uma abundância de 258,80 árvores por hectare, que corresponde a 85,8% do total dos indivíduos. O incremento periódico anual em diâmetro observado no período de 2003 a 2010 foi de 1,19 mm ano-1, e verificou-se a distribuição diamétrica de J – Invertido. A floresta de mopane apresenta um crescimento lento e pouca diversidade de espécies, sendo importante a aplicação de intervenções silviculturais e estabelecer o plano de manejo de acordo com o ritmo de crescimento da espécie e estrutura horizontal e vertical dos remanescentes a serem manejados.Embrapa Florestas2012-12-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/30610.4336/2012.pfb.32.72.421Pesquisa Florestal Brasileira; v. 32 n. 72 (2012): out./dez.; 421Pesquisa Florestal Brasileira; Vol. 32 No. 72 (2012): out./dez.; 4211983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/306/pdf_17Bila, Jacob MiguelMabjaia, Nazaréinfo:eu-repo/semantics/openAccess2017-04-28T12:55:53Zoai:pfb.cnpf.embrapa.br/pfb:article/306Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2017-04-28T12:55:53Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
