Nineteenth-century land use shapes the current occurrence of some plant species, but weakly affects the richness and total composition of Central European grasslands.

Context: Historical land use is thought to have influenced plant community diversity, composition and function through the local persistence of taxa that reflect ecological conditions of the past.
Objectives: We tested for the effects of historical land use on contemporary plant species richness, composition, and ecological preferences in the grassland vegetation of Central Europe.
Methods: We analyzed 6975 vegetation plots sampled between 1946 and 2021 in dry, mesic, and wet grasslands in the borderland between Austria, the Czech Republic, and Slovakia.
Seven years of chronic fertilization affects how plant functional types respond to drought, but not plant production.

Nitrogen deposition continues to change grassland plant community composition particularly in more mesic systems; however, whether these altered plant communities will respond differently to other global change factors remains to be seen. Here, we explore how nutrient-altered tallgrass prairie responds to drought. Seven years of nutrient treatments (control, nitrogen (N), phosphorus (P), and N + P) resulted in significantly different plant communities.

Article Synopsis
- Drought events are becoming more common in grasslands and shrublands, affecting soil organic carbon (SOC), which includes different forms like particulate (POC) and mineral-associated organic carbon (MAOC).
- A global study over 19 sites revealed that in wetter areas (aridity index > 0.65), extreme drought led to a significant decrease in SOC (7.9%) and POC (15.9%), but MAOC levels remained unchanged.
- In drier regions (aridity index < 0.65), drought did not significantly affect any type of soil organic carbon, indicating that the impact of drought on SOC is influenced by environmental aridity and rainfall variability.
Effect of mowing versus abandonment of mesic grasslands in Central Europe on biomass use for biogas production: Implications for semi-natural ecosystem conservation.

Botanical Garden, Faculty of Biological Sciences, University of Wrocław, Poland.
The economic management of lignocellulosic biomass from semi-natural grasslands is now a challenge across Europe. The abandonment of mowing these grasslands leads to the gradual degradation of these ecosystems. This study investigates how chemical and biological factors affect the suitability of biomass from abandoned grasslands for biogas production.

Grazing practices affect the soil and vegetation of grasslands, which further influence the provision of ecosystem services and the productivity of grasslands. We determined the ecosystem resilience of a mesic grassland under three grazing management systems in the Pakkies area, (30°33'08''S, 29°25'22'' E), South Africa: cooperative (continuously grazed since 2017), commercial (rotationally grazed for >20 years), and communal (continuously grazed for >20 years) farms. This was carried out by measuring the penetration resistance and infiltration, soil nutrients, forage quality contents for livestock, veld condition, plant species composition and richness, and functional diversity.
