Forest restoration methods, seasonality, and penetration resistance does not influence aboveground biomass stock on mining tailings in Mariana, Brazil

Abstract: The restoration methods applied on the areas affected by the Fundão tailings dam collapse have a high priority in Mariana region. We evaluated the effect of different restoration methods and site preparation techniques, depth and seasonality on penetration resistance of tailings, and how these predictors affect tree aboveground biomass in areas affected by the Fundão dam collapse in Mariana, Brazil. No significant differences in penetration resistance and aboveground biomass between treatments were observed, b… Show more

“…The deposition of tailings on secondary Atlantic forest along these rivers and their tributaries was restricted to a 113 km area from the Fundão dam to the Risoleta Neves hydroelectric plant, called Environmental Area 1 (Martins et al 2020a). The ecological restoration activities on these affected areas combining different methods and techniques of active and passive restoration are being applied to recovery plant diversity and ecosystem services, such as aboveground biomass (AGB) stock (Campanharo et al 2020, 2021; Martins et al 2020a, 2020b). These methods are typically used in contrasting context‐dependent conditions, for example, passive restoration is usually successful where the vegetation spontaneously recovers by natural regeneration (Holl & Aide 2011; Holl 2017), meanwhile active restoration is recommended in degraded areas where natural regeneration is hindered or limited (Holl 2012; Martins 2018; Campanharo et al 2020).…”

“…Thus, monitoring ecological indicators (i.e. plant community diversity, composition, structure, and functions) of rapid assessment and direct positive effects on Atlantic forest ecosystem functioning contributes to a better understanding of restoration practices and guides further activities and projects (Campanharo et al 2020, 2021; Martins et al 2020a, 2020b).…”

“…Entretanto, existem áreas em que outras técnicas podem ser indicadas como exclusivas ou até como complementares para aumentar a biodiversidade dos próprios reflorestamentos tradicionais (Martins et al 2020a(Martins et al , 2020b. Nesse contexto, a semeadura direta de espécies arbóreas nativas, tem sido utilizada em projetos de restauração (ex, Campanharo et al 2020Campanharo et al , 2021Martins et al 2020b).…”

“…Com o rompimento da barragem de Fundão, em Mariana, Minas Gerais, Brasil, muitos investimentos têm sido realizados pela Fundação Renova e seus parceiros buscando a restauração das áreas afetadas direta e indiretamente pelo rejeito (MARTINS et al, 2020;VILLA et al, 2021). Diversos métodos e técnicas de restauração ativa e passiva estão sendo utilizadas e recomendadas para as diferentes situações encontradas em campo, entre elas: o reflorestamento com plantio em área total com mudas de espécies nativas, técnicas de nucleação, condução da regeneração natural e restauração passiva (MARTINS et al, 2020;CAMPANHARO et al, 2021;SILVA et al, 2021). A definição da técnica a ser utilizada em determinada área a ser restaurada está diretamente ligada com as características específicas do local, não existindo uma metodologia padrão a ser aplicada , OLIVEIRA & ENGEL, 2017TRENTIN et al, 2018).…”
