Resumo: | In Southern Brazil, the National Forests (NF) are protected areas of sustainable use; however, most of them present a significant cover with old plantations of Pinus spp. established to foster commercial forestry. Nowadays, the NF management plans propose the conversion of Pinus stands into native forests. Pinus spp. are worrisome invasive plants whose spontaneous recruitment is a challenge to forest restoration. This paper aims to analyze seed rain and woody community composition in a stand where Pinus trees were eliminated to drive spontaneous regeneration (REG) in an NF in the Southern Atlantic Forest. The seed rain was measured in the restoring area and inside an adjacent Pinus stand (PIN). The tree community structure was analyzed comparatively in REG, PIN, and in a Native Araucaria Forest (NAT). One year after Pinus cutting, the seed rain of woody species was 1,802 and 1,502 seeds m-2.year-1 in REG and PIN, respectively. REG’s seed rain had higher diversity than PIN and absence of Pinus seeds. REG and NAT presented higher diversity of tree species than PIN, although REG had the lowest basal area and tree density. Nevertheless, 188 Pinus seedlings.ha-1 were observed in REG, which indicates that complementary restoration actions are needed. |

Forest regeneration and seed rain in the conversion of a stand of Pinus sp. into native forestRegeneração florestal e chuva de sementes na conversão de um talhão de Pinus sp. em floresta nativaIn Southern Brazil, the National Forests (NF) are protected areas of sustainable use; however, most of them present a significant cover with old plantations of Pinus spp. established to foster commercial forestry.

Porém, a grande maioria apresenta cobertura significativa de plantações de Pinus spp., estabelecidas para promover a silvicultura comercial. Atualmente, seus planos de manejo propõem a conversão de povoamentos de Pinus em florestas nativas. Pinus spp. são invasoras preocupantes, cujo recrutamento espontâneo é um desafio para a restauração florestal. Este trabalho objetivou analisar a chuva de sementes e a composição da comunidade lenhosa em um estande em que os indivíduos de Pinus foram eliminados para conduzir a regeneração natural (REG), em uma NF na Mata Atlântica Meridional. A chuva de sementes foi quantificada na área em restauração (REG) e dentro de um estande adjacente de Pinus (PIN). A estrutura da comunidade arbórea foi analisada em REG, PIN e em uma Floresta de Araucária Nativa (NAT). Um ano após o corte do Pinus, a chuva de sementes de espécies lenhosas foi de 1.802 e 1.502 sementes m-2.ano-1 em REG e PIN, respectivamente. REG apresentou maior diversidade que PIN e não apresentou Pinus na chuva de sementes. REG e NAT apresentaram maior diversidade de espécies arbóreas que a PIN, embora a REG tenha apresentado as menores densidade e área basal. No entanto, 188 plantas jovens de Pinus sp.ha-1 foram observadas na REG, indicando a necessidade de ações complementares de restauração.Universidade Federal de Santa Catarina2021-06-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/7681410.5007/2175-7925.2021.e76814Biotemas; v. 34 n. 2 (2021); 1-182175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCenghttps://periodicos.ufsc.br/index.php/biotemas/article/view/76814/46545Copyright (c) 2021 Geraldo Ceni Coelho, Rachel Palhares Alcantara, Maurício Zinn Klemann, Leandro Klemannhttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCoelho, Geraldo CeniAlcantara, Rachel PalharesKlemann, Maurício ZinnKlemann, Leandro2021-06-01T15:26:36Zoai:periodicos.ufsc.br:article/76814Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2021-06-01T15:26:36Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false |

In Southern Brazil, the National Forests (NF) are protected areas of sustainable use; however, most of them present a significant cover with old plantations of Pinus spp. established to foster commercial forestry. Nowadays, the NF management plans propose the conversion of Pinus stands into native forests. Pinus spp. are worrisome invasive plants whose spontaneous recruitment is a challenge to forest restoration. This paper aims to analyze seed rain and woody community composition in a stand where Pinus trees were eliminated to drive spontaneous regeneration (REG) in an NF in the Southern Atlantic Forest. The seed rain was measured in the restoring area and inside an adjacent Pinus stand (PIN). The tree community structure was analyzed comparatively in REG, PIN, and in a Native Araucaria Forest (NAT). One year after Pinus cutting, the seed rain of woody species was 1,802 and 1,502 seeds m-2.year-1 in REG and PIN, respectively. REG’s seed rain had higher diversity than PIN and absence of Pinus seeds. REG and NAT presented higher diversity of tree species than PIN, although REG had the lowest basal area and tree density. Nevertheless, 188 Pinus seedlings.ha-1 were observed in REG, which indicates that complementary restoration actions are needed. |
