Resumo: In Brazil, there are forest fragments inserted in the urban area under threat of degradation. The Desamparo Forest (Araguari-MG) is an important forest protecting springs at an urban park. This study aimed the phytosociological survey of trees from a forest gradient and perform soil analysis. Twenty-five plots of 20 x 20 m were plotted and sampled all trees with the 1.30 m ≥ 15 cm of circumference and also collected soil samples at 0-20 cm depth for chemical analysis as well as soil moisture and the sloping ground. To determine whether the chemical properties, soil moisture and the slope influenced the distribution of plant species in the forest fragment, it was performed canonical correspondence analysis (CCA). The community had a very high number of species (94) and trees (1760), with occurrence of edge species and common open areas even in the forest hinterland, which indicates that there are human impacts on the community. CCA showed the environmental heterogeneity with the formation of three groups, one formed by the plots near to the river bed with higher soil moisture and lower slope, other plots formed with large slope with predominance of generalist species of dry forest, and other strongly correlated aluminum. Therefore, this forest fragment can be considered an important urban relict with high species richness but however past impacts influence the structure of the tree community, which is in an intermediate stage of succession.

A Mata do Desamparo (Araguari - MG) é uma importante formação florestal que protege nascentes existentes em um parque urbano. O objetivo desse estudo foi realizar o levantamento fitossociológico da vegetação arbórea do gradiente florestal e realizar análises de solo. Foram plotadas 25 parcelas de 20 x 20 m, dispostas em quatro blocos e amostrados todos os indivíduos arbóreos com circunferência a 1,30 m ≥ 15 cm e também coletadas amostras de solo a 0-20 cm de profundidade para análises químicas, umidade do solo e o desnível do terreno. Para averiguar se as propriedades químicas, umidade do solo e o desnível influenciaram na distribuição das espécies vegetais do fragmento florestal foi realizada a análise de correspondência canônica (CCA). A comunidade apresentou elevada riqueza (94 espécies) e número de indivíduos (1760) muito elevado em relação a outras florestas da região e adensamentos de espécies de borda e comuns de áreas abertas mesmo na região mais interiorana da floresta, o que indica que existem impactos antrópicos sobre a comunidade arbórea. A CCA demonstrou a heterogeneidade ambiental com a formação de três grupos, um formado pelas parcelas próximas ao leito do rio com maior umidade do solo e menor desnível, outro formado por parcelas com grande desnível, com predominância de espécies generalistas consideradas uma floresta estacional semidecidual e outro fortemente correlacionado com alumínio. Assim, este fragmento florestal pode ser considerado um importante relicto urbano com grande riqueza de espécies, no entanto, impactos passados influenciaram a estrutura da comunidade arbórea, que está em um estágio intermediário de sucessão.Universidade Federal de Santa Maria2017-12-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/3032210.5902/1980509830322Ciência Florestal; Vol. 27 No. 4 (2017); 1415-1428Ciência Florestal; v. 27 n. 4 (2017); 1415-14281980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/30322/16800Copyright (c) 2017 Ciência Florestalinfo:eu-repo/semantics/openAccessVale, Vagner SantiagoAraújo, Glein MonteiroOliveira, Alexandre Silva dePrado Júnior, Jamir AfonsoSantos, Lilian Cristina da Silva2017-12-12T00:31:35Zoai:ojs.pkp.sfu.ca:article/30322Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-12-12T00:31:35Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
