Resumo: | We performed a forest growth dynamics study in Acre State, Brazilian southwestern Amazon, where a 20 ha area was logged in 1992. The study was based permanent sample plots (1 ha) established in the logged area and in an unlogged forest immediately after logging operations finished. Forest dynamics parameters were assessed in terms of aboveground dried biomass (AGB). During the study period, three extreme climate events triggered a high impact on both logged and unlogged areas, producing AGB losses greater than those estimated for logging. Twenty years after logging, ingrowth and mortality rates were similar to those expected in an undisturbed forest, and AGB recovery was significantly faster in the logged areas. Forest management, when properly applied, can promote faster forest AGB recovery. We suggest that forest management could be considered as an alternative to adapt to extreme climate events, by promoting controlled disturbances, which should minimize tree mortality and biomass loss. |

O estudo foi baseado em parcelas permanentes (1 ha) estabelecidas dentro da área explorada e na floresta não manejada, imediatamente após o fim das operações florestais. Os parâmetros da dinâmica florestal foram analisados em termos da biomassa seca acima do solo (BAS). Durante o período do estudo três eventos climáticos extremos causaram um elevado impacto tanto nas áreas exploradas como nas não perturbadas por exploração, produzindo perdas de biomassa superiores às estimadas para a exploração. Vinte anos após a exploração, as taxas de ingresso e mortalidade foram semelhantes às esperadas em uma área de floresta não perturbada por exploração e a recuperação da BAS foi significativamente mais alta nas áreas cortadas. Quando praticado de forma adequada, o manejo de floresta pode promover uma recuperação da BAS mais rápida. Nós sugerimos que o manejo florestal pode ser considerado como uma alternativa para adaptação a eventos extremos de clima por meio da promoção de perturbações controladas que minimizem a mortalidade de árvores e a perda de biomassa.Embrapa Florestas2017-12-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/139810.4336/2017.pfb.37.92.1398Pesquisa Florestal Brasileira; v. 37 n. 92 (2017): out./dez.; 493-502Pesquisa Florestal Brasileira; Vol. 37 No. 92 (2017): out./dez.; 493-5021983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1398/608d'Oliveira, Marcus Vinicio NevesOliveira, Luis ClaudioAcuña, Mario Humberto AravenaBraz, Evaldo Muñozinfo:eu-repo/semantics/openAccess2019-01-02T18:39:23Zoai:pfb.cnpf.embrapa.br/pfb:article/1398Revistahttps://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:2019-01-02T18:39:23Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
