“…The dead wood matter (woody debris) on the forest floor supplies enough nutrients to sustain forest diversity. These TBC values are higher than earlier reported values of 41.25 m 2 ha ¡1 by Gairola et al (2011) and 35.66 m 2 ha ¡1 by Singhal et al (1986), but similar to the recorded TBC values of 54-124 m 2 ha ¡1 (Baduni 1996), 67.84-115.18 m 2 ha ¡1 , and 84.03 m 2 ha ¡1 ) from various regions of Garhwal Himalaya.…”

The present study aimed to analyze the regeneration dynamics, population structure, and forest composition in some ridge forests of the Western Himalaya to elucidate the impact of climate change. The highest species richness (trees, 17; saplings, 16; seedlings, 16) was recorded in mixed Rhododendron arboreum forest. The maximum tree density (737 § 25.93 trees ha ¡1 ; mixed Quercus floribunda); sapling density (5342 § 587.54 saplings ha ¡1 ; mixed Quercus semecarpifolia), and seedling density (71,429 § 26,632.29 seedlings ha ¡1 ; mixed Cedrus deodara) were recorded in forests of higher altitudes. The mean basal cover values in these forests oscillated between 39.21 § 1.53 m 2 ha ¡1 (mixed Quercus leucotrichophora) to 87.65 § 15.45 m 2 ha ¡1 (mixed Abies pindrow). The highest Shannon index value (0.51 § 0.05) and species evenness (0.36 § 0.02) for trees were recorded in mixed Rhododendron arboreum forest. Some species like Betula utilis, Myrica esculenta, Ficus rumphii, Ilex dipyrena, Quercus floribunda, Litsea elongata, Symplocos paniculata, and Abies spectabilis were noticed as new recruiters (recent invaders) in new habitats, which may change the future forest composition. This study revealed that ridge forests of the Bhagirathi catchment area were in transition phase at middle altitudes. Mixed Quercus floribunda forest was observed to be the youngest regenerating forest; however, mixed Abies pindrow forest was the most mature old-growth forest.

“…Gairola et al (2011) also referred A. acuminatum as the dominant species in A. pindrow forest (2500-2600 m a.s.l.). However, in this study, A. acuminatum was not recorded as the top dominant species due to lower importance value and limited population size which was found growing well with A. pindrow.…”

“…The recorded diversity index values were lesser to the earlier reported values i.e., 2.66 for Q. leucotrichophora; 2.53 for Q. floribunda and 1.41 for Q. semecarpifolia forests (Singh and Rawat 2012), 1.2 to 2.7 for Q. floribunda forest (Kumar and Ram 2005), 0.76 to 1.50 for Q. floribunda forest (Lodhiyal et al 2013). However, Gairola et al (2011) have reported the diversity index values as; 0.46 for Q. semecarpifolia forest and 0.49 for Q. floribunda forest, which were closer to our values. The herb diversity was more than trees and shrubs in all the Oak forests ( Table 1).…”

“…Our values are best fitted with the previously reported values for biomass production i.e., 387. Q. semecarpifolia forest at 2,650-2,850 m asl were also reported by Gairola et al (2011) for Oak mixed forests. However, the biomass production of 272.…”

The present study was conducted on ridge tops of moist temperate Oak forests in Garhwal Himalaya to assess the plant diversity, regeneration, biomass production and carbon assimilation in different Oak forests. For this purpose, ). The total biomass density (TBD) across three Oak forests ranged between 497.32±83.70 (FT1) and 663.16±93.85 t ha -1 (FT3), while the total carbon density (TCD) values ranged between 228.75±22.27 (FT1) and 304.31±18.12 t ha -1 (FT3). Most of the tree species were found with good regeneration (GR) status (average 45%) in all the forest types whereas, few species were found not regenerating (NR) (average 17%) however, few new recruitments were also recorded. ANOVA (Post-Hoc Tukey's test at 5% significance level) indicated significant forest-wise differences in TBC, TBD and TCD (in tree layer); family and evenness (in shrub layer only) values, while insignificant differences were noticed in density values of tree, seedling and herb layer.

“…Sumeet et al [16] noted that findings from studies that address patterns of plant distribution and dynamics of biological resources can provide a rational basis for planning and making decisions about the environment. Otherwise, restoration of resources in their natural habitat would be very difficult [17].…”

Abstract:The objective of this study is to analyse the phytodiversity, distribution, herb biomass and physico-chemical conditions of the vegetation system in the context of communal continuous open grazing and enclosed grazing management practices in the Harishin rangelands of Eastern Ethiopia. A total of 58 herbaceous species and 11 woody species were recorded in the study area. Analysis of Importance Value Index for two management practices was represented by different combinations of species with varied dominance. The herbs' diversity-dominance curve revealed a lognormal distribution in both managements practices. The overview of distribution patterns for most of the species layer showed contiguous growth and a clumped distribution pattern. Species diversity, richness, herb biomass, basal cover and soil physico-chemical attributes showed a distinct separation in relation to grazing management practices. Based on the findings, one can conclude that the establishment of enclosures has a positive impact in restoring rangeland vegetation diversity, distribution, in increasing herb productivity and in boosting soil fertility.
