Knowledge on seed ecology is foundational for effective seed‐based restoration including seedling production, direct sowing, topsoil transplant, and natural regeneration. Consequently, quantifying available knowledge biases in research allows practitioners to better plan implement programs identify priorities. Using a systematic review comprising 45 papers, 401 species, 2,415 case studies, we provide an overview of the Pantanal, world's largest tropical wetland. We identified geographic, taxonomic, ecological biases, as well gaps functions dispersal, dormancy, germination, predation, stress tolerance. Studies concentrated near large cities resulting extensive unexplored sites central Paraguay, Bolivia. Unexpectedly, most studied species were conducted with dry‐fruited, terrestrial forbs, or shrubs autochoric zoochoric dispersal syndromes. Seed banks, tolerance, topics, whereas studies dormancy establishment remain rare. also found disproportionate interest across angiosperm tree life many examples underrepresented overrepresented families. Altogether, persistent Pantanal hinder upscaling consequently likelihood achieving targets UN Decade Ecosystem Restoration. propose integrated agenda consisting series orchestrated actions overcome such barriers, close biodiversity shortfalls, promote successful large‐scale Pantanal.

To facilitate the restoration of disturbed vegetation, seeds wild species are collected and held in dry storage, but often there is a shortage for this purpose. Thus, much research effort expended to maximize use available ensure that they nondormant when sown. Sowing (versus dormant) field should increase success restoration. Of various treatments break seed dormancy, afterripening, is, dormancy during most cost-effective. Seeds can undergo afterripening have nondeep physiological includes members common families such as Asteraceae Poaceae. In review, we consider differences between terms moisture content, temperature time required discuss conditions which rapid could lead aging death if storage too long. Attention given induction secondary become via biochemical molecular changes occurring storage. Some recommendations made managing so at sowing. The important recommendation probably germination responses need be monitored germinability/viability period.

Grasslands and savannahs are suffering heavy losses from degradation conversion. The UN Decade on Ecosystem Restoration offers important opportunities to address these through a range of restoration techniques. However, if poorly planned, the could undermine some remaining natural semi‐natural grassland savannah ecosystems by encouraging afforestation areas, thus acting as perverse incentive. This article outlines main issues steps needed ensure that creates positive outcomes for highly biodiverse ecosystems: (1) better understanding status trends in degraded converted grasslands savannahs; (2) making case at both national international levels; (3) ensuring post‐2020 biodiversity conservation targets all ecosystems; (4) improving selection tools avoid displacing valuable (5) identifying successful approaches ecological, cultural, social needs.

Despite growing recognition of the conservation value grassy biomes, our understanding how to restore biodiverse tropical and subtropical biomes (grasslands savannas; TGB) remains limited. Several tools have recently been identified for TGB restoration, including prescribed fires, appropriate management livestock wild herbivores, tree cutting shrub removal, invasive species control, reintroduction native grasses forbs via seeding or transplants. However, additional research improved restoration is needed. This article aims identify ecological priorities restoration. The following points are crucial scale up meet challenges UN Restoration Decade. Research should focus on: disentangling reasons why often undervalued misunderstood; mapping opportunities; identifying regions where other naturally exist as alternative stable states; recognizing areas with natural regeneration potential avoid unnecessary intervention; restoring soil conditions; factors driving low seed quality, determining germination requirements developing vegetative propagation techniques species; limiting key processes underlying seedling establishment community assembly; improving validating long‐term mimic disturbance regimes; setting minimum attributes desirable in terms structure, composition, functioning, resilience; monitoring outcomes. Such has advance theory, policy, practice ultimately resulting benefits people nature some more neglected ecosystems planet.

Such misconceptions have detrimental consequences biodiversity, ecosystem services, human livelihoods woodlands, savannas, grasslands worldwide. Here, we demystify TGB myths to promote a positive agenda increase likelihood success ambitious landscape‐scale goals nonforest ecosystems. 10 are: (1) originate from degraded forests, (2) tree cover is reliable indicator habitat quality, (3) planting trees always good biodiversity (4) are biodiversity‐poor provide few (5) enhancing plant nutrition needed restoration, (6) disturbance detrimental, (7) techniques used restore also work TGB, (8) represent early stages succession, (9) grassland only about grasses, (10) fast.

Soil salinization poses an important threat to terrestrial ecosystems and is expected increase as a consequence of climate change anthropogenic pressures. Conventional methods such salt-leaching or application soil amendments, nature-based solutions (NBSs) phytoremediation, have been widely adopted with contrasting results. The use cyanobacteria for improving conditions has emerged novel biotechnological tool ecosystem restoration due the unique features these organisms, e.g., ability fix carbon nitrogen promote stabilisation. Cyanobacteria distribute over wide range salt concentrations several species can adapt fluctuating salinity conditions. Their in agricultural saline remediation demonstrated, mostly laboratory studies, but there lack research regarding their natural restoration. In this article, we provide overview current knowledge on context Examples alleviating salt-stress plants soils are presented.

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.

Context Kangaroo grass (Themeda triandra Forssk.) is a native perennial C4 species significant to Dja Wurrung people who seek restore its presence across Country (Djandak) through broadacre seed crop production. To achieve this, agronomic challenges establishment must be overcome. Aims understand the effects of harvest time on viability and sowing establishment. Methods In Experiment 1, was assessed in remnant Djandak stand three seasons colour cumulative shed measured two these seasons. 2, from ecotypes sown at sites eight dates over plant emergence, culm number canopy cover were recorded. Key results mid-December late-January varied intra- inter-seasonally. Viability early low (0–24%) but increased with peak 68–69% first 28–37% final season. Most had when reached. Dark-coloured seeds caryopsis exhibited both high dormancy. September–October resulted optimal combination highest mean establishment, lowest variability no failures. Conclusions maximise should harvested 30–50% has shed. Implications These guidelines inform T. supportive development as crop.
