Soil Seed Banks in a Forest Under Restoration and in a Reference Ecosystem in Southeastern Brazil

Abstract: The current study aims to characterize the soil seed banks in a forest under restoration and in a seasonal semideciduous forest remnant, as well as to quantitatively and qualitatively compare them in order to evaluate the seed bank potential to influence the restoration process. In total, 60 samples of soil seed banks were collected in two adjacent forests (30 in a 2.18-ha forest undergoing restoration process based on the planting of seedlings belonging to different tree species, after the forest was subjecte… Show more

“…The highest proportion of pioneer species and individuals, in both areas under restoration (F1 and F2), confirms data from other studies on soil seed banks in Minas Gerais [33,35,37,43] and in other forest formations in Brazil [44] . Thus, the predominance of native pioneer species in the seed bank is due to the ability to form a persistent bank in the soil due to long seed viability, high seed production, efficient dispersion mechanisms and because they normally show fast growth at full sun, being an excellent indicator of resilience to natural or man-made disturbances [32] .…”

“…These variations in the density of soil seeds in different areas can be related to several factors such as the type of disturbance, history of the area, the presence and quantity of dispersers and geographical barriers [34] . As observed, most of the species and individuals sampled in the seed bank are herbaceous (F1 and F2), which is common in this type of study, as noted by Balestrin et al [20] , Costalonga [35] , Martins [36] and Silva et al [37] as a characteristic of disturbed environments. In addition, the predominance of this life form can be explained by the life cycle of these species, high seed production and history of agricultural use in the area (pasture and coffee plantation), among other factors.…”

“…Seed banks can contain high diversity of species (Ferreira et al 2015, Braga et al 2016, Silva et al 2019, providing resilience and regeneration of native species (e.g. Guimarães et al 2012, using topsoil) and presenting high density of viable seeds (Martins 2007, Pilon et al 2018).…”
