“…The lower albedo of forests can lead to warming, which can offset some of the positive effects of carbon sequestration from afforestation (Rohatyn et al 2022). Conversely, grasslands have higher albedo and are a key soil carbon sink, storing about one-third of the world's terrestrial carbon (White et al 2000). The full potential for grasslands as carbon sinks requires more attention and remains unrealized at present.…”

In times of unprecedented climate change, ecological restoration efforts have a strong focus on forests for the purpose of carbon sequestration. Grasslands, in contrast, remain relatively neglected in global restoration policies. Concurrently, we are in the midst of a biodiversity crisis-it is estimated that 1 million species are globally threatened with extinction. Here, we present analyses from central Europe and southern Brazil that show that the majority of our endangered plant species are in fact found in open ecosystems. Using Germany as an example, we show that we could reduce plant extinction risk by up to 82% if we restore open, grassy ecosystems. This also holds true for southern Brazil, where grassland species constitute the single largest share of endangered species, but where grassy ecosystems continue to be systematically neglected by restoration policies. We further expand on our biodiversity argument to include the role that grassland restoration can play in mitigating climate change. We posit that ramping up grassland restoration efforts may not only be our best bet to bend the curve of biodiversity loss, but it will also make a critical contribution to the resilience of ecosystems in the dynamic decades to come. It is time for grassland restoration to receive higher priority in global restoration efforts and policy.

“…nonwoody species) represent c . 40% of the terrestrial land surface on Earth (White et al ., 2000), facilitate large quantities of carbon sequestration (reviewed by Bai & Cotrufo, 2022), and provide much of the food production for humans (O'Mara, 2012). Many of these ecosystems are currently in danger of being lost due to global change drivers, shrub encroachment, and calls for afforestation (Bond et al ., 2019).…”

“…Grasslands are one of the most numerous and widely distributed biomes on the Earth's surface. Factors defining grassland biomes are climatic conditions, grazing and fire (White et al, 2000; Zhou et al, 2017). They develop in arid and semi‐arid areas, with seasonal cold and dry periods, and high rates of evapotranspiration (Barnett & Facey, 2016; Knapp et al, 2002; Lenhart et al, 2015).…”

Grassland biomes provide valuable ecosystem services, including nutrient cycling. Organic phosphorus (Po) represents more than half of the total P in soils. Soil microorganisms release organic P through enzymatic processes, with alkaline phosphatases, acid phosphatases and phytases being the key P enzymes involved in the cycling of organic P. This study analysed 74 soil metagenomes from 17 different grassland biomes worldwide to evaluate the distribution and abundance of eight key P enzymes (PhoD, PhoX, PhoA, Nsap‐A, Nsap‐B, Nsap‐C, BPP and CPhy) and their relationship with environmental factors. Our analyses showed that alkaline phosphatase phoD was the dataset's most abundant P‐enzyme encoding genes, with a wide phylogenetic distribution. Followed by the acid phosphatases Nsap‐A and Nsap‐C showed similar abundance but a different distribution in their respective phylogenetic trees. Multivariate analyses revealed that pH, Tmax, SOC and soil moisture were associated with the abundance and diversity of all genes studied. PhoD and phoX genes strongly correlated with SOC and clay, and the phoX gene was more common in soils with low to medium SOC and neutral pH. In particular, P‐enzyme genes tended to respond in a positively correlated manner among them, suggesting a complex relationship of abundance and diversity among them.
