Resumo: The objective of this study was to evaluate the thinning into strips and the enrichment with exotic grasses in a Caatinga area in order to maintain and increase the biodiversity of native vegetable species and forage production. Two studies were carried out—one in an area of Caatinga thinned into strips and one in an unmanipulated Caatinga area—during the rainy and rainy-dry season transition periods in 2016. The production of herbaceous biomass was evaluated, and the diversity and equability of the two areas were assessed through Shannon-Weaver (H’) and Pielou (J’) indexes. The establishment of massai and buffel grasses at the center and edges of the area thinned into strips was also evaluated. During the rainy season, the production of herbaceous biomass in the area thinned into strips and the unmanipulated area was 1,228 kg ha-1 and 833.33 kg ha-1, while during the rainy-dry transition period, it was 1,973 kg ha-1 and 836.00 kg ha-1, respectively. The indexes remained similar: H’ (1.86) and J’ (0.74) for the area thinned into strips, and H’ (1.77) and J’ (0.85) for the unmanipulated area. The massai grass presented better establishment and development than that by the buffel grass in the center and edges of the area thinned into strips. Thus, thinning into strips increases the biodiversity of an area, and this combined with enrichment through grasses increases the biomass of herbaceous forage.

Dois estudos foram conduzidos em uma área de Caatinga raleada em faixas e em outra área de Caatinga não manipulada no período chuvoso e transição águas-seca no ano de 2016. Avaliou-se a produção de biomassa herbácea e, a diversidade e equabilidade pelos índices de Shannon-Weaver (H’) e Pielou (J’) das áreas raleada em faixas e não manipulada. Foi ainda avaliado o estabelecimento dos capins massai e búffel ao centro e na lateral da área raleada em faixa. Na época das águas a produção de biomassa herbácea na área raleada em faixas e não manipulada foi de 1.228 kg ha-1 e 833,33 kg ha-1, enquanto o período de transição águas-seca 1.973 kg ha-1 contra 836,00 kg ha-1, respectivamente. Os índices permaneceram próximos H’ (1,86) e J’ (0,74), para a área raleada e H’ (1,77) e J’ (0,85) para a não manipulada. O capim-massai apresentou melhor estabelecimento e desenvolvimento que o capim-búffel no centro e na lateral da área raleada em faixas. O raleamento em faixas aumenta a biodiversidade da área contribuindo juntamente com o enriquecimento no incremento de biomassa de forragem herbácea.Universidade Federal Rural do Semi-Árido2019-08-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/799710.1590/1983-21252019v32n326rcREVISTA CAATINGA; Vol. 32 No. 3 (2019); 814-825Revista Caatinga; v. 32 n. 3 (2019); 814-8251983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/7997/10067Copyright (c) 2019 Revista Caatingainfo:eu-repo/semantics/openAccessConrado, Jefte Arnon de AlmeidaCavalcante, Ana Clara RodriguesTonucci, Rafael GonçalvesCarneiro, Maria Socorro de SouzaCândido, Magno José Duarte2023-07-20T17:41:06Zoai:ojs.periodicos.ufersa.edu.br:article/7997Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:46:37.815329Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true
