“…In the post‐monsoon period, decline in temperature and moisture brought about ending in new growth and a gradual decline in live shoot biomass (Joshi et al, 2012). In conformity to previous studies (Ensslin et al, 2015; Jhariya & Singh, 2021) few important species contributed to bulk of biomass. The total herb biomass across the sites was higher than the value reported by Bazzaz & Bliss (1971) and Gosain et al (2015) in certain forest and shrub communities.…”

In Kumaun Himalaya, the shrublands dominated by Coriaria nepalensis are present in patches and due to their facilitative nature enhance the restoration of degraded hills.This study deals with the dry matter dynamics of C. nepalensis shrublands. The equation for C. nepalensis was developed to measure the biomass and to understand the dry matter dynamics through compartmental models. Total biomass of tree, shrub and herb varied from 71.66 to 217.40 t ha À1 , 43.65 to 77.55 t ha À1 and 11.11 to 64.55 t ha À1 , respectively. The biomass of herbs was higher during monsoon and lowest during the summer season. Litter fall varied from 1.02-1.70 t ha À1 yr À1 and the highest value of litter fall was recorded during winter (52%) followed by rainy (29%) and summer season (19%). Order of contribution of different components to total litter fall was: foliage (45.32%-50.33%) > twigs (36.80%-42.22%) > miscellaneous litter (4.62%-6.97%) > Bark (3.56%-5.47%) > reproductive parts (2.13%-3.57%). Shrub floor biomass was recorded maximum during the rainy season (11.32-37.55 t ha À1 ) followed by the winter season (13.03-25.36 t ha À1 ) and minimum in the summer season (6.83-12.80 t ha À1 ). Net primary productivity in trees, shrubs and sapling was ranged from 0.94 to 11.01, 1.83 to 4.88 and 0.55 to 0.87, respectively. Due to less canopy cover, the litter fall was less than from the majority of the forest types of the region. Thus, proper conservation and management measures must be designed to improve the structural components and functional traits of the shrubland ecosystem to enhance the ecological services on sustained basis.

“…The tropical forest degradation due to anthropogenic disturbances, fragmentation of forest stand, and habitat and alteration in land‐use causes the deleterious impact on the structure, composition, biodiversity, biomass and C accumulation and dynamics, soil N, and nutrient stocks to a great extent (Jhariya & Singh, 2021a, 2021b; Khan et al, 2020a, 2020b). This leads to disturbances in the soil–plant system that affects the natural recovery mechanism, ecosystem structure, and associated ecological services (Bartels et al, 2016).…”

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.

The impact of NPK fertilizer on growth and nutrient accumulation in juniper (Juniperus procera) trees grown on fire-damaged and intact soils

Wildfires significantly alter soil properties and result in vegetation shifts; therefore, rapid reforestation activities are needed in the forests affected by wildfires. The decreased nutrient in the soil is the obvious effect of wildfires; however, little is known about the reforestation of Juniper (Juniperus procera) forests with application of NPK fertilizers. Juniper forests are common in Asir and Taif regions of Saudi Arabia and vulnerable to wildfires; thus, reforestation is needed after the onset of fires. This study assessed the impact of different doses of organic NPK fertilizer (0, 5 and 10 g/L) on growth and nutrient accumulation of Juniper trees grown on fire-damaged and intact soils. Data relating to tree height, number of leaves per plant, fresh and dry biomass accumulation in shoot and root, chlorophyll contents and uptake of N, P, K, and Na were recorded. Individual and interactive effects of soil types and fertilizer doses significantly altered all measured traits with minor exceptions. Overall, higher values of the measured traits were recorded for intact soil and 10 g/L fertilize dose. The increasing fertilizer doses improved the growth and nutrient acquisition and application of 10 g/L fertilizer on intact soil recorded the highest values of growth traits. Juniper trees grown on fire-damaged soil accumulated higher amount of nitrogen than intact soil. Similarly, the trees grown on intact soil accumulated lower amount of Na and maintained comparable K/Na ratio to intact soil. It is concluded that supplying 10 g/L fertilizer could improve the establishment of Juniper trees on fire-damaged soil. Therefore, organic fertilizer can be used to improve the reforestation of wildfire-affected Juniper forests in the Asir province.
