“…To better harness the potential of natural regeneration on old‐fields, it is crucial to understand the role of different sources of propagules contributing to an area's overall regenerative capacity (Lopes et al 2012; dos Santos et al 2016). For natural regeneration to occur, there must be a supply of viable plant propagules (do Nascimento Oliveira et al 2019) as well as suitable conditions for their germination and establishment (Shumi et al 2018; Ligate et al 2019). In addition to those that already occur in situ (e.g., in soils, surface leaf litter or the canopy of remnant vegetation; Heydari et al 2014; Sandor & Chazdon 2014), plant propagules can also arrive at a site via a range of dispersal vectors, including wind, hydrochory (Nilsson et al 1991), zoochory (Dylewski et al 2017; Catterall 2018), or anemochory (Sandor & Chazdon 2014).…”

Revegetating abandoned agricultural lands is vital to restoring critical ecological functions and services. Natural regeneration, whereby vegetation regrows via the seeds already present within the landscape, has shown to be an effective approach to restoring large agricultural areas, although more research is required to understand the regenerative capacity of the various seed sources. Here, we investigate the regenerative capacity of old‐fields of semi‐arid floodplains of eastern Australia in a year‐long seedling emergence experiment. We examined the germinable seed banks from three potential propagule sources (soil, leaf litter, and animal scats) collected across 24 field sites, comprising 12 old‐fields and 12 adjacent remnant vegetation patches, distributed across four regions. Soil seed banks stored the most germinable species of the three seed bank types, although these were dominated largely by annual herbaceous species. High abundances of seedlings emerged from scat samples, indicating that native animals, such as kangaroos and emus, play a role in transporting seeds in these landscapes. Finally, leaf litter stored the most germinable propagules of woody species, therefore, representing a vital mechanism for woody vegetation regeneration. There were few differences in emerging seedling assemblages in terms of species richness, abundance or composition between seed banks of old‐fields and adjacent remnant vegetation, suggesting that old‐field seed banks have a high level of resilience. Our findings suggest that these seed banks can make an important contribution to natural regeneration of these old‐fields, but mainly with respect to understory and midstory species, with overstory tree species mostly absent from these seed sources.

“…This vegetation presents degradation processes, such as deforestation, which alter floristics and natural regeneration. However, the elimination of vegetation cover causes serious environmental problems in the Northeastern Semi-arid, among which the reduction of biodiversity and soil degradation, mainly by mining, stand out [7][8][9].…”

This research aims to identify and analyze the level of regeneration of Caatinga vegetation in different stages, under the impact of granite-gneiss mining in a semi-arid region in Northeast Brazil. To carry out the floristic and phytosociological survey, four areas of vegetation cover were selected in different stages of regeneration: 20 years (closed bush shrubland); 15 years (open bush shrub); 10 years (sub-shrub Caatinga); 50 years (reference area with shrubby Caatinga). The species records of the four sampled areas were compared using the Jaccard and Sorensen similarity index. For the phytosociological analysis, the parameters of Basal Area, Absolute and Relative Density, Absolute and Relative Dominance and Coverage Value of the species were calculated. The floristic survey registered 5,494 individuals belonging to 14 families and 34 species. It was found that Euphorbiaceae and Fabaceae were the families that contributed with the largest number of species in the tree and shrub components. The species in the areas where there was exploitation 20 and 15 years ago showed a regeneration process close to that registered in the preservation area for 50 years. However, with respect to wealth, the 20-year area showed the greatest abundance. From the results it was possible to know the process of regeneration of the pioneer and secondary successional species in the Caatinga, contributing to the preservation of the species and the recovery of degraded areas in the semi-arid region of Paraíba. Contribution/Originality: The exploitation of granites and gneisses has a high economic impact in the state of Paraiba. There are extensive areas under environmental impact and biological loss due to the removal of vegetation. We characterize the rate of regeneration of Caatinga vegetation with a history of exploitation of these rocks.
