“…The higher number of species, density, and basal area in UF (Table 1) are due to direct consequence of protection that lead to presence of higher number of species and population due to favourable site conditions and lesser mortality and stressed condition as compare to the DF (Mota et al, 2017). This reflects good regenerative potential of the species and stable growing environment and pattern in UF than the DF (Crovo et al, 2021). Further, the greater ecological amplitude and good capacity of regeneration of species in the UF lead to overall plant health in terms of their quantitative phytosociological characteristic as compared to the DF.…”

The tropical deforestation due to biotic interference, land use change, and population explosion in Asian countries has attracted the global concern with respect to conservation and protection of forest resources. Indian soils are limited in terms of nutrient reserves and organic matters. Our present study deals the influence of disturbance on phytosociology, vegetation carbon (C), and nitrogen (N) along with soil properties of tropical deciduous forest in Chhattisgarh. The stratified random sampling technique was used for quantifying the vegetation. Results revealed that 43.75% species are rare in occurrence in undisturbed forest (UF), and in disturbed forest (DF) about 50% species showed rarity over the area as per the Raunkiaer frequency class of species rarity and commonness. Total density and basal cover were 1090 trees ha À1 and 28.16 m 2 ha À1 , respectively. in UF and was 190 trees ha À1 and 10.99 m 2 ha À1 in DF. The disturbance resulted into 31.63% loss in total biomass in DF compared to UF. The increasing disturbances are altering the forests attributes in terms of poor standing stock, basal area, and diversity in DF. The concentration of dominance and beta diversity value was higher in DF. It may be increased due to influx of generalist species in DF. Stand biomass was found to be 3-times higher in UF than the DF. Higher value of C and N stock and soil nutrient were found in UF. Thus, proper conservation, protection, and restoration of these forests should be the priority to improve the C pool and ecological services.

“…However, inconsistencies of soil nutrients in these soil types might be caused by uncontrolled or heavy grazing practiced in these farms. Large quantities of mineralization increased nutrient uptake by stressed plants ( Crovo et al., 2021 ; Abdalla et al, 2018 ), and this can play part in lowering the available macro nutrients in the soil. Moreover, Ragimov et al (2020) also alluded that high grazing intensity does decline in the net productivity of the rangeland, resulting in the defeat of palatable species and soil chemical properties.…”

Communal Property Associations (CPAs) rangeland users need more knowledge on the state of their respective grazing lands and also the interaction of soil properties with grazing management implemented. This study aimed to investigate the effect grazing has on the physical and chemical properties of four different soil types found in selected CPAs of the Bela-Bela municipality, they are as follows: Mawela (Hutton-clay loam: HCL), Bela-Bela (Hutton-clay: HC), Moretele (Hutton-loamy sand: HLS) and Ramorula (Ecca sand-clay loam: ESCL).The macro and micro minerals, pH, nitrate-nitrogen, ammonium-nitrogen, organic carbon, soil particle size distribution, acidity and resistance were all measured. All data were subjected to two-way factorial analysis of variance (SAS, 2010). The topsoil was sampled at a depth of 300 mm at an interval of 100 m (100 and 200 m) from the same transect used for woody species data collection resulting in a total of 18 samples per CPA. In each CPA, three camps were selected. In each camp, three transects 200 m apart at the length of 200 m were set. In each transect, soils were drawn at 0, 100 and 200 m making a total of nine soil samples per each camp. The highest (P < 0.05) pH (7.14) recorded on the sub-soil was in HLS. Nitrate nitrogen (2.4 mg/kg) concentration on the topsoil was high (P < 0.05) in HC soil type. Soil organic carbon for both topsoil (0.66%) and subsoil (0.41%) was significantly lower (P < 0.05) in HLS soil type and ESCL soil type respectively. Phosphorus concentration was significantly high (P < 0.05) in ESCL soil type for both topsoil (12.86 mg/kg) and sub-soil (1.59 mg/kg). Iron concentration was high in both topsoil (11.8 mg/kg) and sub-soil (7.3 mg/kg) in ESCL soil type. Sub-soil manganese concentration was found to be higher (P < 0.05) in ESCL soil type (7.58 mg/kg). Soil resistance (2880 Ω ) measured in topsoil was high (P < 0.05) in HCL soil type compared to other soil types. Moreover, for the sub-soil the highest (P < 0.05) resistance (least salts) (3640 Ω) was recorded in ESCL soil type. For most of the soil types, the mineral concentration was higher in topsoil than in sub-soil, this trend explains that the uptake of these minerals by plants took place due to the inconsistencies of grazing management employed in these selected CPA farms. It is of colossal significance to properly manage rangelands, to allow a fair-to-good herbaceous layer in the presence of minerals in the soils and farmer should prioritize having enclosures and keeping N-fixing tree species in the rangelands to achieve the above mentioned conditions.

“…Despite the higher litter quality (higher N content) in the degraded forest, it tended to accumulate more N than in the secondary forest. This N enrichment could result from external inputs from grazing livestock in the degraded forest area (69).…”

“…C:P and N:P values indicated a period of initial immobilization and high mineralization towards the end of this study. This initial accumulation may be due to external sources, for example, the precipitation and fall of new litter from the canopy (70) and also livestock grazing (69). The content of P decreased drastically starting in spring, which suggests more substantial mineralization of this element and reabsorption after the rainy season.…”

IntroductionAnthropic disturbances are driving unprecedented changes in forest ecosystem functions and biogeochemical processes, hindering the forests’ benefits to society. Litter decomposition is one of the most critical processes that regulate forests’ carbon and nutrient cycling. However, how forest degradation affects litter decomposition and elemental dynamics requires further examination. The main objective of this study was to evaluate the effect of forest degradation on the production and decomposition of litter and C,N, and P dynamics in a temperate forest in south-central Chile.MethodsLitter traps and litter bags were installed in three Long Term Research Forest Plots (LTER) representing different conservation states: mature, secondary, and degraded Nothofagus forests.Results and DiscussionThe total litter input varied between 3.5 to 1.1 Mg ha–1 year–1 in the mature and degraded forests, respectively. We found the highest lignin and nutrient levels in the degraded forest and the lowest in the mature forest. In the mature forest, 44% of the initial litter was decomposed, while in the degraded forest it only reached 7%. Decomposing litter showed the lowest C:N and C:P ratios in the mature forest most of the year. The balance between inputs and outputs yielded a more substantial litter accumulation in the mature forests.ConclusionOur results strongly suggest that anthropogenic degradation altered litter quality and nutrient dynamics while decreasing litter production and decomposition.
