This study was undertaken in three different forest cover types which were dominated by Quercus incana, Persea duthiei and Abies pindrow, respectively. The aim of the present study was to investigate the regeneration pattern of dominant tree species along the altitudinal gradient in Darhal watershed, situated in the Pir Panjal mountain region of Jammu and Kashmir State. A total of 14 tree species were recorded. The tree density varied between 492 to 1325 individuals/ ha, whereas the total basal area ranged between 25.88 to 188.90 m 2 ha -1 . In general the density of seedlings, saplings and trees increased with increase in elevation. All the three forest types have poor regeneration. The recruitment of Q. incana seedlings and the rate of conversion of A. pindrow seedlings to saplings and then saplings to young tr...

The present study investigated the effect of different land uses i.e. forests viz. mixed forest cover (MFC), Prosopis juliflora (Sw.) DC dominated forest cover (PFC), and cultivated viz. agriculture field (AF), vegetable filed (VF), respectively, on soil parameter, microbial activity, and enzymes involved in soil nutrient cycle in a semi-arid ecosystem.Results The results showed a significant reduction (P

We measured the SR and soil environmental factors over 1 year in four land uses with varying levels of disturbance and different vegetation types viz., mixed forest cover (MFC), Prosopis juliflora (Sw.) forest cover (PFC), agricultural field (AF), and vegetable field (VF), in a semi-arid area of Delhi, India. Our primary aim was to assess the effects of soil moisture (SM), soil temperature (ST), and soil microbial activity (SMA) on the SR. Methods The SR was measured monthly using an LI-6400 with an infrared gas analyser and a soil chamber. The SM was measured using the gravimetric method. The ST (10 cm) was measured with a probe attached to the LI-6400. The SMA was determined by fluorescein diacetate hydrolysis. Results The SR showed seasonal variations, with the mean annual SR ranging from 3.22 to 5.78 μmol m...

The present study investigated the effect of different land use, i.e., forests viz. mixed forest cover (MFC), Prosopis juliflora (Sw.) DC-dominated forest cover (PFC), and cultivated sites viz. agriculture field (AF), vegetable field (VF), respectively, on soil parameter, microbial activity, and enzymes involved in soil nutrient cycle in a semiarid region of India. Results The results showed a significant reduction (P < 0.05) in soil carbon (SC), soil nitrogen (SN) content (~ 30–80%) and consequently the soil microbial biomass carbon (SMBC) (~ 70–80%), soil basal respiration (SBR), soil substrate-induced respiration (SSIR), and soil enzyme activities (β-glucosidase, acid phosphatase, and dehydrogenase) under cultivated sites in comparison with forest sites. Pearson’s correlation showed that a positive correlation of SC with SMBC, SBR, SSIR (P < 0.01)...
