Initial growth crown cover of cerrado species from different sucessional groups

Abstract

This study had the objective to evaluate the initial growth and crown cover of native cerrado species of different successional groups in planting forest restoration in Chapadão do Sul, MS, with an experiment installed in February of 2013 to test restoration models. Twelve species were selected, being four pioneers: Anadenanthera falcata, Cybistax antisyphilitica, Platypodium elegan and Samanea tubulosa; four early secondary species: Dipteryx alata, Sterculia striata, Alibertia edulis and Enterolobium contortisiliquum; and four late secondary species: Cedrela fissilis, Copaifera langsdorfii, Handroanthus roseo-albus and Hymenaea stilbocarpa. Diameter at soil height (DSH), total height and crown diameter were measured at 8, 14, 20 and 26 months after planting. the periodic increase in height and DSH were calculated by species, group and age, and the crown area at 26 months. The highest increases in height and DSH were from the pioneers group and from the early secondary until 26 months, and the lowest increases were from the late secondary species. The species within each group vary their initial investment in height and DSH. The pioneers group presented the largest crown areas, while the late secondary group presented the smallest.

Fertility responses of a native grass: technology supporting native plant production for restoration in Brazil

“…Although planting seedlings is the most extensively adopted technique used in the restoration of ecosystems worldwide (Wortley et al 2013;Palma & Laurance 2015), and the most studied in the Cerrado region (Guerra et al 2020), the low availability of native herbaceous pot-grown plants in commercial nurseries limits the use of this technique to restore Cerrado's grasslands and savannas (Vidal et al 2020). Consequently, most of the Cerrado restoration by planting seedlings has been focused solely on trees (Felfili et al 2005;Silva & Corrêa 2008;Forlin et al 2020). However, dense planting of tree seedlings can threaten the biodiversity and ecosystem services provided by the Cerrado's grasslands and savannas (Honda & Durigan 2016;Abreu et al 2017;Veldman et al 2015;Haddad et al 2020).…”
