Disturbed Environment

The present study focuses on the forest structure of highly disturbed sites in Western Himalayan regions in Pakistan. In this study, the regeneration potential of conifer species is a key point for the assessment of future conifer status in disturbed environment by employing multivariate techniques. The forests are composed of four conifer species Pinus wallichiana A. B. Jacks, Pinus roxburghii Sarg., Cedrus deodara (Roxb.) G. Don, and Abies pindrow (Royle ex D. Don) Royle., associated with broadleaved species Quercus baloot Griffith, Quercus dilatata Raf., and Aesculus indica (Wall. ex Cambess.) Hook. Cluster analysis shows five groups when Pinus wallichiana (PW) forms the largest group, incorporates with other conifers and broadleaved species and in some cases it overlaps with its subgroups forming a pure larger group. Similarly in DCA (ordination) overlapping exists in all the axes while elevation is the only variable that shows a highly significant (P < 0.001) correlation with conifers. Cedrus deodara (CD) with Quercus baloot (QB) and Aesculus indica (AI) shares a significant (P < 0.05) correlation in the same habitat while there is no correlation between the remaining conifers. It is anticipated that overlapping in cluster analysis and ordination and non-significant correlations in cluster analysis and ordination are due to the highly disturbed nature of the sites. It is also suggested that seedling recruitment and development are highly affected due to the anthropogenic disturbance. Therefore, proper maintenance of the forest, proper management and conservational practice should be imposed.

A general investigation of sub-tropical forests, from Pir Chinasi National Park, Tolipir National Park, Dhirkot Nature Reserve and Banjosa Game Reserve was carried out during different months from February 2008 to May 2010. The relative abundance of species was calculated using line transects of 50m. A total of five different species (Abies pindrow. Cedrus deodara, Pinus wallichiana, Pinus roxburgii and Picea smithiana) from the Pinaceae family were recorded. The main reported use of Cedrus deodara and Pinus wallichiana by the local people was for furniture and construction purposes. Pinus wallichiana was observed as the dominant species from all the selected sites.

Two community forests, Amaldapani and Juphal from Dolpa district, were selected for a study of quantitative analysis of tree flora. A total of 419 individual trees representing 16 species, 16 genera and 11 families were recorded. Total stand density and basal area were, respectively, 2100 trees ha-1 and 90 m2ha-1 in Amaldapani and 2090 tree ha-1 and 152 m2ha-1 in Juphal. Of the families, the Pinaceae was the most diverse, with 28 individuals representing five species and five genera, followed by the Rosaceae with three individuals representing two species and two genera. Pinus wallichiana, Abies spectabilis, Quercus semecarpifolia and Cedrus deodara had the highest importance value index and could therefore be considered the dominant species. Since the study area was diverse in tree population of conifers and deciduous forest tree species, it is essential to carry out further studies in order to establish conservation measures that will enhance local biodiversity.

First Time

Fungi associated with roots of Pinus wallichiana A.B. Jackson were evaluated for the first time in the recently published study by Tyub et al. (2018, Can. J. For. Res. 48(8): 923–929, doi: 10.1139/cjfr-2018-0084 ). A culture-free approach using RFLP profiling and the sequencing analysis of DNA extracted from fine root tips was used to identify ectomycorrhizal and other species present in the roots; however, numerous inconsistences in the interpretation of presented results indicated that the names assigned to particular sequences were incorrect. Therefore, sequences belonging to ascomycete microfungi (predominantly members of Helotiales) obtained in the study were reanalyzed to confirm their identification. A simple phylogenetic analysis also utilizing closely related sequences from GenBank showed that the sequences from this study were mostly misidentified (i.e., placed in different clades than sequences having the same name but originating from taxonomic studies). Erroneous conclusions resulting from misidentified species and limited knowledge of relevant literature were corrected. Despite numerous inconsistences, the study of Tyub et al. (2018) brought valuable data about fungal diversity and potential taxonomic novelties among helotialean fungi associated with coniferous roots.

Fungal Associations

An important factor in the performance of out-planted conifers is the association of plant roots with ectomycorrhizal (EcM) fungi. However, limited information is available about the diversity of root-associated EcM fungi of Pinus wallichiana A.B. Jackson, a coniferous species endemic to Himalayan forests that has hampered the reforestation programs in the area. The study was carried at three major forest areas of the Kashmir Himalaya believed to be pure stands of P. wallichiana. Fine root tips harbouring EcM fungi were collected and processed for extraction of fungal DNA, which was subsequently subjected to ITS rDNA targeted PCR–RFLP profiling. DNA sequencing analysis of the overlapping ITS amplifications followed by global nucleotide BLAST analyses of the assembled nuclear ribosomal DNA (rDNA) revealed a total of 33 fungal taxa associated with P. wallichiana of which 23 species were EcM fungi. Of the 10 non-EcM fungi, we found a peculiar saprophytic wood decaying fungus, Chalara microchona, associated with P. wallichiana for the first time. The study not only reveals the species richness of fungi associated with this conifer but also documents new fungal associations with it, which have not been reported so far. The results in the study set a baseline for the broad association of ectomycorrhizal fungi with P. wallichiana, which may serve as guiding cue to design reforestation programs in the Kashmir Himalaya.

This article encompasses the impacts of disturbance, regeneration potential of conifers and the dynamics of tree species seedlings along the spatial scale in Murree forest. The seedling status preferably of conifers along with associated broadleaved dominant tree species is determined by a quantitative evaluation of diversity functions. An empirical approach is applied to predicting the future of seedlings under stress as well as the current hypothetical appearance of seedlings in the forest. The need of analysing diversity of this forest is due to highly disturbed conditions there, and this paper is designed to know the recent trends of species diversity in the area. Species diversity and species abundance at a seedling level are estimated by using standard formulas of diversity measurements. Thirty stands are used for the evaluation of seedling abundance in highly disturbed conditions with the examination of diversity in the area. Seedling density is too low in the forest whereas diversity is also in poor condition. Seedlings from four conifers with three broadleaved species in different stands indicated the low density of future trees. The mean density·ha<sup>–1</sup> of pine seedlings is consecutively low in Pinus wallichiana (16 ± 2), Pinus roxburghii (11 ± 3), Cedrus deodara (9 ± 3), Abies pindrow (8 ± 3). The correlation coefficient is as low as 0.76, 0.66 and 0.61 in Pinus roxburghii, Cedrus deodara and Abies pindrow, respectively, while Pinus wallichiana showed a significant correlation, i.e. P &gt; 0.5. Hence, this study claims that the survival of the forest is threatened as seedling density and diversity are too low. This forest needs serious attention towards preventing and conserving pines and other associated species seedlings for the existence of this forest in future.
