Topsoil volume optimization in the restoration of post‐mined areas

Restoration Ecology, Journal Year: 2024, Volume and Issue: 32(7)

Published: July 7, 2024

Transferring topsoil to severely degraded areas, such as mined is an effective restoration technique. However, from pristine areas a limited resource, making it important seek techniques that optimize its use. Thus, this study assessed the effects of adding small volume (10 L/m 2 or 1 cm layer), seed mix 14 species, and litter (30 ) alone in different combinations rupestrian grassland area by bauxite mining. The substrate was turned prior applying treatments. Vegetation cover, density individuals, species richness were measured 30 months after experiment set up. isolated use each material simultaneous addition not effective. topsoil, litter, provided best result, presenting highest vegetation coverage (60%), (67 ind/m ), (26 12 m ). Although, lesser extent, combination also presented satisfactory results. three materials promoted revegetation had been without for around 50 years, individuals comparable those obtained with thick layers (15–30 cm). Furthermore, used optimized.

Abstract Upscaling trait‐based restoration to regional levels is necessary as we enter the UN Decade on Ecosystem Restoration. For this, need select species that achieve functional targets considering pool. Here, present a framework multiple using pool containing available market, unavailable, and occur in reference ecosystems.

Beyond tree planting: Mobilizing a global production network for savanna restoration in Brazil

Environmental Development, Journal Year: 2024, Volume and Issue: 51, P. 101017 - 101017

Published: June 7, 2024

Emerging global production networks innovate the supply of restoration products and services to reverse degraded ecosystems globally. Yet, savanna interventions often neglect diverse plant life forms planting techniques in implementing large-scale pledges. Drawing on network analysis, we examine how configuration practices Brazil influences decision-making processes outcomes. Our assessment a case study Central reveals myriad forces affecting interconnections between institutional drivers, markets, systems for actions across multiple scales. Prevailing policies regulations disregard expertise, economic strategies, socio-cultural perspectives when setting priorities incentives. While identify different buyers influencing market demands meet mandatory or voluntary environmental compliance, wide range suppliers remakes according regional contexts.

Low‐cost technology supports propagation of endemic species from a global biodiversity hotspot

Restoration Ecology, Journal Year: 2025, Volume and Issue: unknown

A widespread myth in tropical grassy biome restoration is that most native plants are not amenable to propagation. This untested assumption has hampered the development of productive chains campo rupestre , a megadiverse edaphic grassy‐shrubby ecosystem where species often produce large proportion embryoless or nonviable, minute seeds. Likely, arises due limited and testing techniques for seed cleaning plant propagation, coupled with lack synthesis current successful techniques. Here, we conducted series experiments on germination propagation endemics, providing evidence dispel this persisting foster grassland restoration. First, adapted flotation method—a reliable, low‐cost, fast, low‐technology technique—that successfully separates high‐quality seeds from low‐quality ones. Germination floating was significantly lower than precipitated all species, indicating effectiveness method. We also ran showing under nursery conditions equal outperformed chambers, suggesting laboratory studies might underestimate potential species. Our experiment indicates high seedling production relatively survival rates growth common settings.

What to expect from restored Cerrado grasslands? Indicators and reference values from pristine ecosystems

Restoration Ecology, Journal Year: 2025, Volume and Issue: unknown

Open ecosystems are disappearing worldwide, requiring urgent restoration efforts. However, limited knowledge of their structure and composition hinders the assessment success. We aimed to establish reference values for plant community attributes in undisturbed native grasslands guide restoration. In an unprecedented data collection, we sampled 14 remnants under different climate, soil, fire regimes, representing a broad portion Brazilian savanna (except least converted northern). assessed composition, richness at scales, ground cover by functional groups, aboveground biomass. From 794 species recorded, half were unique occurrences, few present over 70% areas. Richness ranged from 9 22 species/m 2 53 130 30 m . Grasses (22–80%) non‐grasses (9–45%) did not entirely, leaving 4–56% exposed. Biomass 57 715 g/m Because is variable, finding “reference set” whole Cerrado possible. Regional subsets key guilds recommended instead. The number good proxy diversity, species/30 total richness. unreliable indicator due natural range independent integrity. maximum biomass, however, should never be surpassed. Structural targets include grasses, non‐grasses, bare soil within range, but achieving pristine may unrealistic most cases. Strong efforts focus on conservation rather than restoration, once recovering all reference's difficult.
