Management of natural pasture increases native and exotic herbaceous biomass and biodiversity in the Caatinga of Brazil

Abstract: The objective of this study was to evaluate the ability of savanna thinning and enrichment with grasses to maintain local biodiversity and intensify biomass production in an area of Caatinga. The study was carried out in a Caatinga area thinned into savanna and an unmanipulated area during the rainy and rainy-dry transition seasons of 2016. The herbaceous biomass production, diversity, and equability of the thinned and unmanipulated areas were evaluated by calculating values of the Shannon-Weaver (H′) and Piel… Show more

“…This species requires at least 450 mm of rainfall and has a robust and deep root system. The biomass accumulated by this plant, both in the aerial and root parts, can contribute to the nutrient cycling dynamics in the agroecosystem ( Monção et al 2011 ;Martins et al 2013 ;Conrado et al 2019 ;Freitas et al 2022 ). Additionally, pigeon pea ( Cajanus cajan [L.] Millsp.)…”

“…Esta técnica consiste no controle seletivo de espécies lenhosas, por meio da qual se elimina da vegetação alguns indivíduos arbustivo-arbóreos, reduzindo a densidade de plantas e a cobertura do solo pelo estrato lenhoso(PIMENTEL, 20106). No tocante à remoção seletiva de árvores e arbustos por meio do raleamento, esse manejo é pensado com o intuito de melhorar o processo de colonização, reduzindo a competição por água, luz e nutrientes, abrindo mais espaço para o crescimento de espécies herbáceas de pequeno porte(GUO, 1998;SAVADOGO et al, 2008;CONRADO et al, 2019). Portanto, o aumento da disponibilidade de plantas herbáceas em florestas secas têm sido obtido através de modificações na estrutura e arquitetura da vegetação arbóreo-arbustiva (ARAÚJO FILHO et al, 2013).…”
