“…All three relative values were summed up to determine Importance Value Index (IVI) [44,45]. Diversity Index like the Simpson Diversity Index (D) was calculated by following the formula by Simpson [5,46], and the Shannon-Wiener Index (H') was computed according to Shannon and Wiener [47,48]. Species Richness (R) was documented by following Margalef [49,50] and Species Evenness (E) was calculated by following Pielou [51,52].…”

This study aimed to assess the long term effects of anthropogenic, climatic, edaphic, and seasonal variations on present floristic and ecological status of two distinct sites i.e., protected (Biodiversity Park) and unprotected (nearby areas) in the Derawar region of Lesser Cholistan Desert. The study was conducted for four years over a seasonal period of spring 2019 (February-March) to fall 2022 (September to October). For the exploration of maximum diversity at both sites, quadrats of 10 × 10 m were placed randomly. Ten soil, twelve anthropogenic, seven environmental and eight seasonal variables were used to assess their relationship with vegetation of both sites during four years of study. For statistical analysis, data was processed in the SPSS for LSD test and R Studio for Canonical Correspondence Analysis (CCA) and heat map preparation. A total of 84 plant species, belonging to 62 genera and 26 families, were identified in the Derawar region. Herbaceous plants comprised the majority, with 42 species, followed by grasses (22 species), shrubs (12 species), trees (7 species), and one sedge species. The protected site exhibited higher species diversity, with 76 species from 23 families, compared to the unprotected site, which had 49 species from 15 families. Species richness, Simpson index, and Shannon index showed significant declines in diversity from the protected to the unprotected site.

“…The IVI value indicates the ecological significance of a species in a particular area, accordingly, species having a higher IVI value have higher relative dominance than other species in the study area (Zafriakma et al, 2020). In the present study, five species with top IVI values were selected from each of the altitudinal classes (Supplementary table 1) and evaluated their potential contribution toward total biomass (Fig.…”

It has been reported that the large cardamom-based traditional agroforestry systems in the Darjeeling Himalaya of West Bengal, India represents a sustainable land use system with a high potential to store and sequester biomass carbon. Therefore, the present study was undertaken to evaluate the changes in tree biomass stock and carbon accumulation of this indigenous system with altitude. The study area was classified into three altitude-classes as low (700–1200 m asl), mid (1200–1700 m asl) and high (> 1700 m asl). The tree biomass and carbon storage for low-, mid- and high-altitude classes was estimated at 630.17 and 296.18 Mg ha− 1, 397.05 and 186.61 Mg ha− 1 and 315.78 and 148.42 Mg ha− 1, respectively. Schima wallichi, Cryptomeria japonica and Cupressus cashmeriana were the most ecologically important tree species based on IVI (important value index) in the low-, mid-, and high-altitude classes, respectively. The IVI and total biomass of the five most ecologically important tree species in low-, mid- and high-altitude ranged from 17.34–26.04, 18.15–37.56, 27.13–42.43 and 9.05-133.75 Mg ha− 1, 1.38–37.43 Mg ha− 1 and 19.0-72.1 Mg ha− 1, respectively. Schima wallichi occurred in all the altitude-classes among the five most ecologically important tree species. In the study area, the average ecosystem carbon storage was estimated at 295.02 Mg ha− 1. The contribution of soil organic carbon to the ecosystem carbon stock increased with the increasing altitude. In contrast, the contribution of biomass carbon to the ecosystem carbon stock decreased with the increase in altitude. The ecosystem carbon stock estimated for the low-altitude class was 36.43% and 45.30% higher than the mid- and high-altitude agroforestry systems. The large cardamom-based agroforestry systems in the Darjeeling Himalayas are thus a prospective carbon sink, both in vegetation and soil due to higher tree densities and natural resource conservation-based traditional farming practices.
