The dynamics and plant composition of toxic weeds in alpine meadows are strongly influenced by management practices such as livestock grazing. Here, the effect grazing on vegetation soil characteristics within an meadow ecosystem was assessed over a 5-year period. experimental treatments comprised no (control), light (5 sheep/ha), moderate (10 heavy (15 sheep/ha). both edible grass weeds, along with soil’s physicochemical biological properties, were evaluated. Under grazing, biomass increased 15.0%, while species decreased 57.0% compared to control. findings indicated that after 5 years, changed significantly, Taraxacum mongolicum Tibetia himalaica decreasing disappearing under treatments. Conversely, like Stellera chamaejasme Euphorbia micractina emerged or Additionally, richness from 6.3 control 14.2 Regarding levels glucosidase, amylase, cellulose 39.0%, 53.0%, 40.0%, respectively. amount available potassium initially then results demonstrated quality cover properties directly depend land management. Overall, kept better chemical state palatable plants at desirable level, which also controlled abundance weeds. Enhancing nutrient conditions, adding nitrate fertilizers, can be effective restoring grasslands have been severely degraded

Abstract Understanding how vegetation traits and soil characteristics respond to grazing in grasslands is fundamental their restoration management. Here, we investigated changes species diversity, plant productivity, total nitrogen (STN), organic carbon (SOC) storage following grazer exclusion at three grassland sites along an elevation gradient the Kashmir Himalaya. Plant cover, aboveground belowground biomass (AGB BGB, respectively), SOC, STN increased six years of exclusion, though diversity indices declined over this period. Grazer all functional groups (sedges, grasses, legumes, forbs), with sedges, particularly Carex muricata , showing highest increase. effects on AGB varied elevation, most pronounced effect detected site. vertical distribution root biomass, were restricted topsoil (10 cm) low‐elevation but extended deeper layers high‐elevation sites.

Understanding the impact of grazing management strategies on alpine meadow is fundamental importance for grassland conservation. However, vegetation and soil properties in response to different implemented Kobresia pygmaea remains elusive. In this study, a medium-term field experiment with three (free grazing, FG; no NG; reduced RG) was conducted. The results revealed that total aboveground biomass (AGB), cover litter increased significantly under NG treatment, whereas belowground (BGB) decreased plot. Furthermore, responses plant functional groups were varied. AGB grass remarkably treatment compared FG plot, there obvious change sedge, legume, forb groups. concentrations available phosphorus (AP) ammonia nitrogen (NH4+-N) RG considerably at 0–5 cm layers. contrast, C:N ratios all layers similar among strategies. It worth noting AP concentration positively correlated AGB. More importantly, supported equilibrium hypothesis versus BGB, which based unique biological characteristics K. meadow. Our study provides valuable insights into can thus provide guidance designing degraded
