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.

Abstract Background Cerrado grasses are closely linked to fire, but the mechanisms underlying their responses poorly understood. Fire affects populations by altering vital rates, and different regenerative strategies likely influence as resprouting ability trades off with seeding investment. Specialist mostly occupy old‐growth habitats rely almost entirely on vegetative regeneration, suggesting potentially higher fire tolerance than habitat generalists that can colonize anthropized degraded due high Thus, we explored effect of one specialist ( Trachypogon spicatus ) two generalist Aristida riparia Schizachyrium microstachyum tussock grasses. Location Frequently burned grassland in Central Brazil. Methods We monitored rates 150 individuals/species (prescribed late‐dry‐season fire) unburned plots. Survival, resprouting, reproduction were assessed monthly for six months post‐fire then again 16 after fire. Tussocks measured size (area base) height changes structure. collected seed mass, fill, germination from literature. Results negatively affected grasses, increasing mortality (+12%), decreasing (50%), inhibiting flowering inflorescence production. The benefited burns, showing survival (97%), recovery pre‐fire structure, stimulated reproduction. Generalist species had a investment seeds (seed fill > 60%; 50%), while produced empty (88%) low (3%). Size was not related probability significantly increased reproductive output. Conclusions suggest could persist under very frequent fires (e.g., annual), given its robust recovery. Where this is restoration priority, it would benefit techniques promote regeneration rather direct seeding. Contrarily, less resilient require longer intervals allow population persistence.

Abstract Selecting the best seed sources is a key step in ecological restoration planning especially under climate change. Seed‐provenancing strategies include composite, aiming to reproduce natural gene flow; predictive, focusing on future adaptation; and climate‐adjusted, combination of composite predictive.

To fill this methodological gap, we developed C limate‐ O riented S eed‐ ourcing T ool (COSST), tool built R capable suggesting priority areas for sourcing according or climate‐adjusted strategies, as well site focal species.

Grassland restoration efforts typically aim to recover lost biodiversity, guided by biologically diverse old‐growth grasslands as a benchmark. In most grasslands, forbs greatly outnumber grasses in terms of richness and therefore contribute diversity, but globally, practitioners continue disproportionately focus on increasing perennial grass cover. While such grass‐centric approaches might be appropriate for meeting some goals, an number studies reveal negative effects cover forb total plant diversity restored grasslands—with cascading consequences other trophic levels grassland functionality. To that end, we urge recognize the biodiversity costs embrace forb‐centric meet goal restorations.

Societal Impact Statement Large quantities of diverse native seeds are required to scale up global restoration efforts. However, it remains unclear for many ecosystems how the diversity available seed in commercial stocks reflects composition where vegetation is being remade.

Excluding invasive grasses is a significant challenge for neotropical savanna restoration. Invasive alter fire regimes with feedbacks on soil nutrient pools, favoring their own dominance over native species. Here we combine remote sensing an opportunistic experiment to monitor under restoration before and after large natural fire. We measured vegetation fertility in 4‐year‐old area Central Brazil, which was subsequently hit by lightning The originally utilized as pasture, dominated grasses. Over the period, fast‐growing replaced Within first year fire, found that had reduced aboveground biomass, species diversity, abundance of acquisitive resource‐use strategies. Soil phosphorus pH increased favored re‐invasion exotic grass Our findings suggest occurrence early process may trigger driven enrichment. To diminish risk from savannas undergoing restoration, managers should beware or manage events. Successful also benefit incorporating high post‐fire recovery capacity.
