“…The soil component as limiting factor may frustrate attempts at restoration (Bulot et al, 2017;Jim, 2001). The most widely used technique and which is considered as the best for rehabilitating the reference ecosystem is soil transfer (Bulot et al, 2017;Fowler et al, 2015). Our results show that in the long term, the replacement of the topsoil by transfer presents characteristics that are virtually similar to those of the steppe topsoil.…”

Quarrying represents one of the oldest and most important human activities; the impacts of which have largely influenced vegetation and landscape. Despite its character as a vital and non-renewable resource, the soil has been poorly studied with regard to either the impact resulting from the exploitation of quarries or its restoration after exploitation. In the plain of La Crau (south-eastern France), numerous dry alluvial quarries were exploited in the 1970s. Their exploitation lasted about ten years and they were then rapidly abandoned. At that time, there was no legal obligation to restore sites after their abandonment. In this context, following various modes of exploitation (e.g. exploitation depth), various rehabilitation options were implemented: no rehabilitation, topsoil transfer, deposits of anthropogenic materials. The absence of legislation consequently resulted in heterogeneous areas after their abandonment. Today, we have the benefit of 35 years of hindsight on the dynamics of these ecosystems resulting from these exploitation modes and rehabilitation options and thus various questions arise: (1) Did the diversity of the modes of exploitation result in heterogeneous soils 30 years after abandonment? (2) At what stage of pedogenesis are the soils created in the abandoned quarries? (3) Did the various rehabilitation options have an impact on the traces of biological activity in the soils of the quarries? (4) Is it possible to identify methods of rehabilitation of quarries that would favour the rehabilitation of the soils and the recolonisation of the plant cover in order to improve the techniques in use or to propose alternative methods? The study of soil profiles (with a special focus on biological activity of animals and plants) and soil physico-chemical analyses (pH, CaCO 3 , C, N, C:N ratio, CEC, exchangeable K + , plant available P and fine soil particle contents) made it possible to study these questions. Our results confirm that all the soils resulting from the former exploitation modes and rehabilitation options of the quarries present their own specific characteristics (upper soil layer fertility, soil profile vertical organization) which remain very different, even after 30 years, from the characteristics of the destroyed reference soil ecosystem. Pedogenetic processes are very slow or even blocked by the recurrent action of certain environmental parameters. In terms of ecological rehabilitation, only topsoil transfers undertaken under good conditions (same soil thickness as the reference steppe and no contact with the phreatic zone) have allowed to restore most of the physical and chemical properties recorded close to the reference ecosystem soil.

“…Soil transposition may increase the diversity of regional native species, genetic variability, and the chances of recruiting species adapted to adverse conditions (Reis et al, 2003;He et al, 2016). In this sense, many authors have emphasized the use of the seed bank as an efficient strategy for covering degraded or disturbed areas by including species of different forms of plant life (Tozer et al, 2012;Ferreira et al, 2015;Fowler et al, 2015).…”

Floristic Composition Analysis of Soil Transposition in a Seasonal Forest in Rio Grande do Sul, Brazil

This study aimed to identify the floristic composition and density of a seed bank transposed from a Seasonal Forest fragment in Rio Grande do Sul. The seed bank of the (BSI) fragment center and edge (BSII) of another forest fragment was also evaluated, both at medium to advanced successional stages. The seed bank was deposited in Brown-Gray Argisol and Red Argisol using exposed soil plots as control. ANOVA followed by Tukey test (p<0.05) were used to compare treatments for density and species richness. The density of individuals did not differ between treatments. Species richness was higher for BSI and BSII treatments in relation to control. The floristic composition presented different life forms, but was mainly composed of herbaceous species. It was concluded that the seed bank from the two donor areas contributed to the expansion of species richness in two soil types.

“…A utilização do banco de sementes como estratégia de restauração ecológica é citada por diversos autores (Hall et al, 2010;Miranda Neto et al, 2010;Tozer et al, 2012;Ferreira et al, 2015;Fowler et al, 2015), que observaram o recobrimento das áreas, aumento de espécies e inclusão de diferentes formas de vida. Contudo, destaca-se a carência de informações científicas quanto a utilização da transposição do banco de sementes devido às especificidades ecológicas dos ecossistemas na região sul do Brasil, influenciados fortemente pelo clima subtropical, e a necessidade de validar metodologias de restauração para essa região, que sejam ecologicamente eficientes e, ao mesmo tempo, com menores custos (Rovedder et al, 2014).…”

RESUMOO objetivo deste estudo foi avaliar o potencial da transposição do banco de sementes para restauração ecológica da Floresta Estacional em Santa Maria, Rio Grande do Sul. Avaliaram-se o banco de sementes do centro (BSI) e da borda (BSII) de um fragmento florestal. O solo foi depositado em parcelas de 1 m 2 , em delineamento inteiramente casualizado com três tratamentos (BSI, BSII e Testemunha) e seis repetições, em dois tipos de solo, Argissolo Bruno-Acinzentado (PBAC) e Argissolo Vermelho (PV). Avaliaram-se composição florística, emergência de plântulas, densidade e mortalidade em cada tratamento e tipo de solo durante doze meses. Foi realizado ANOVA com medidas repetidas para comparar os tratamentos em relação à emergência, densidade, mortalidade e riqueza de espécies ao longo de doze meses. Houve diferença significativa entre os tratamentos para riqueza e densidade. O número de espécies foi crescente no decorrer dos doze meses. A densidade foi influenciada pelo período de inverno, onde apresentou decréscimo, e pelo grau de hidromorfia do solo. A transposição do banco de sementes permitiu a inclusão da forma de vida arbórea e mostrou-se eficiente apresentando aumento da diversidade nos locais de deposição.

We evaluated the seed bank of the center (BSI) and the seed bank of the edge (BSII) of a forest fragment. The soil was deposited in 1 m 2 plots in a completely randomized design with three treatments (BSI, BSII and control) and six replications, in two soil types, Argisol Bruno-Greying (PBAC) and Ultisol (PV). We evaluated floristic composition, seedling emergence, density and mortality in each treatment and soil for twelve months. We carried out ANOVA with repeated measures from twelve months to compare treatments in relation to emergency, density, mortality and species richness. There was a significant difference between treatments for richness and density. The number of species has been increasing over the twelve months. The density was influenced by the winter period and degree of soil hydromorphy. Transposition of the seed bank enabled the inclusion of the tree lifeform and demonstrate to be efficient presenting increase diversity in the deposition sites.
