Challenges and opportunities for grassland restoration: A global perspective of best practices in the era of climate change

Global Ecology and Conservation, Год журнала: 2023, Номер 46, С. e02612 - e02612

Grasslands are ubiquitous globally, and their conservation restoration critical to combat both the biodiversity climate crises. There is increasing interest in implementing effective multifunctional grassland restore concomitant with above- belowground carbon sequestration, delivery of credits and/or integration land dedicated solar panels. Other common considerations include improved forage value, erosion control, water management, pollinator services, wildlife habitat provisioning. In addition, many grasslands global hotspots. Nonetheless, relative impact, as compared forests, importance preservation, conservation, has been widely overlooked due subtle physiognomy underappreciated contributions human planetary well-being. Ultimately, success sequestration will depend on more complete ecosystem restoration. this review, supported by examples from across Western world, we call for strenuous unified development best practices three areas concern: initial site conditions preparation; implementation measures management; social context sustainability. For each area, identify primary challenges highlight case studies proven results derive successful generalizable solutions.

Water and wind erosion response to ecological restoration measures in China's drylands

Geoderma, Год журнала: 2023, Номер 435, С. 116514 - 116514

Опубликована: Май 12, 2023

Soil erosion is the most severe form of land degradation threatening terrestrial ecosystems globally. Drylands with fragile are particularly sensitive to soil erosion. China's drylands face threat by wind and water. Currently, more studies need be focused on water response ecological restoration measures at monthly resolution in these areas. This key understanding measures' effectiveness under changing environments. Here, we assessed from 2001 2020 using G2 model revised equation (RWEQ). The Sequential linear regression slopes (SeRGS) explored intensities. We also discuss mitigation benefits two measures, afforestation grassland restoration. results showed that mild (47.35%) slight (58.76%). Water increased between 2020, while decreased.

Forb diversity globally is harmed by nutrient enrichment but can be rescued by large mammalian herbivory

Communications Biology, Год журнала: 2025, Номер 8(1)

Опубликована: Март 15, 2025

Abstract Forbs (“wildflowers”) are important contributors to grassland biodiversity but vulnerable environmental changes. In a factorial experiment at 94 sites on 6 continents, we test the global generality of several broad predictions: (1) Forb cover and richness decline under nutrient enrichment, particularly nitrogen enrichment. (2) increase herbivory by large mammals. (3) less affected enrichment in more arid climates, because water limitation reduces impacts competition with grasses. (4) families will respond differently mammalian due differences requirements. We find strong evidence for first, partial support second, no third, fourth prediction. Our results underscore that anthropogenic addition is major threat forbs, grazing high herbivore intensity can offset these effects.

Urgent need for updating the slogan of global climate actions from “tree planting” to “restore native vegetation”

Restoration Ecology, Год журнала: 2021, Номер 30(3)

Опубликована: Окт. 28, 2021

The prevailing nature‐based solution to tackle climate change is tree planting. However, there growing evidence that it has serious contraindications in many regions. main shortcoming of global planting its awareness disparity alternative ecosystem types, mainly grasslands. Grasslands, where they constitute the natural vegetation, may support higher biodiversity and a safer, soil‐locked carbon stock than plantations other forests. We suggest replacing “tree planting” by “restore native vegetation.” This improved action terminology reduces risks inappropriate afforestation and, diversifying target does not reduce but increases potential land area for mitigation.

Ecological Grassland Restoration—A South African Perspective

The principal drivers of Grassland Biome conversion and degradation in South Africa include agricultural intensification, plantation forestry, urban expansion mining, together with invasive non-native plants insidious rural sprawl. This biome is poorly conserved dire need restoration, an ecologically centred practice gaining increasing traction given its wide application to people biodiversity this emerging culture renewal. pioneering proponent restoration the mining industry, primarily restore surface stability using vegetation cover. We noticed a historical progression from production-focussed pastures more diverse suites native species habitats landscape. paradigm shift towards proactive “biodiversity approach” necessitates assisted natural regeneration, mainly through revegetation grasses, plugs, sods and/or seeds, long-lived perennial forbs. discuss key management interventions such as ongoing control plants, merits fire grazing, deleterious impacts fertilisers. also highlight areas research requiring further investigation. has limitations best suited restoring ecological processes rather than attempting match original pristine state. advocate conserving intact grassland ecosystems strategy for protecting biodiversity, including small patches disproportionately high conservation value.

Assessing the impacts of historical and future land-use/cover change on habitat quality in the urbanizing Lhasa River Basin on the Tibetan Plateau

Ecological Indicators, Год журнала: 2023, Номер 148, С. 110147 - 110147

Опубликована: Март 20, 2023

The Tibetan Plateau (TP) is a hotspot for biodiversity conservation in the world. Understanding impacts of land-use/cover change (LUCC) on natural habitat quality (NHQ) terms both historical and future urbanization ecological restoration important, but existing studies have only focused total LUCC NHQ TP. This study aims to assess by taking Lhasa River Basin (LRB) as an example. We quantified from 2000 2020 based remote sensing data, simulated during 2020–2030 under scenarios business-as-usual (BAU) cropland conservation. Finally, we used model NHQ. found that improved due exceeded deteriorated urban expansion, resulting showing increasing trend LRB 2000–2020. Under BAU scenario, was projected remain stable. However, protection deteriorate large-scale occupation habitats which will be prominent Chengguan District (NHQ decrease 22.52%). To protect habitats, limiting sprawl implementing are needed.

Abstract Theory predicts a decline in grassland diversity under nutrient enrichment and loss of herbivory, one possible cause is hampered seedling recruitment. Two potential drivers for reduced at the level are diminished light availability caused by surrounding vegetation accumulation dead biomass. To test importance these two mechanisms on early recruitment, we added seeds 15 herbaceous plant species monitored sown natural emergence during growing season full factorial field experiment with addition litter removal fertilization exclusion mammalian herbivores an experimental Central Germany. We used modern LED lamps, mimicking spectrum sun light, to provide small‐statured understorey plants. This novel set‐up allowed us specifically disentangle roles limitation independently combination. In general, herbivore exclusion, but not increased amount Litter number richness 83% 33%, respectively, while had no significant main effect nor did it interact any other factors, affect recruitment even when was removed. addition, negative negligible impact effects were independent removal. Furthermore, unrelated intensity quality, depth, soil moisture, temperature C:N ratio.
