Resumo: The better understanding of floristic composition and structure of natural regeneration in differents types of disturbances is essential to identify the degree of recovery of the area and silvicultural interventions to be eventually adopted in order to accelerate the process of forest sucession. The present study aimed to characterize the natural regeneration of 0.4 ha in the natural recovery process in the Experimental Farm of the Federal University of Amazonas aiming to identify the potential of natural regeneration tendency for recovering the area. Tree saplings with height bigger than 10 cm were sampled in five plots of 15 m x 9 m. We registered 148 seedlings and saplings from eight botanical families, nine genera and thirteen tree species. After 14 months without interference, the area was dominated by species of the genus Vismia, which had the highest values of the most structural parameters (density, dominance, frequency, importance and coverage values). The studied site presents natural regeneration with low floristic diversity, dominated by individuals of pioneer species, which may be associated with the previews use as agriculture land, the short period since the last interference and the strong competition with grasses species.

O presente estudo objetivou caracterizar a regeneração natural de 0,4 ha em processo de recuperação natural na Fazenda Experimental da Universidade Federal do Amazonas na expectativa de identificar o potencial da condução da regeneração para a recuperação da área. Foram estabelecidas cinco parcelas de 15 m x 9 m e amostradas as plântulas e os indivíduos arbóreos jovens com altura superior a 10 cm. Foram registrados 148 indivíduos pertencentes a oito famílias botânicas, nove gêneros e 13 espécies arbóreas. Após 14 meses sem interferências, a área foi dominada por espécies do gênero Vismia, as quais se destacaram em grande parte nos parâmetros estruturais (densidade, dominância, frequência, valores de importância e cobertura). O sítio estudado possui regeneração natural com baixa diversidade florística, dominada por indivíduos de espécies predominantemente pioneiras, que pode estar associado ao uso anterior com cultivo agrícola, ao pequeno intervalo de tempo sem interfência e à forte competição com espécies de plantas daninhas.Embrapa Florestas2018-10-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/126510.4336/2018.pfb.38e201601265Pesquisa Florestal Brasileira; v. 38 (2018)Pesquisa Florestal Brasileira; Vol. 38 (2018)1983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1265/677https://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessNogueira, Wanda Lemos PaixãoFerreira, Marciel JoséMartins, Narrúbia Oliveira de Almeida2019-05-10T19:43:45Zoai:pfb.cnpf.embrapa.br/pfb:article/1265Revistahttps://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:2019-05-10T19:43:45Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
