“…However, there are several climber species including Aganosma cymosa, Ampelocissus latifolia, Aristolochia tagala, Asparagus racemosus, Hemidesmus indicus , and the endemic species like Cayratia pedata that are locally threatened but have not been listed (IUCN), rather not evaluated. Similarly, species such as Asparagus racemosus, Ichnocarpus frutescens and Tylophora indica are among the most exploited species for their medicinal uses (Pandian and Ravichandran, 2019), which are not evaluated. Although the majority of the economically valuable climbers are available as cultivars, the continued and non-sustainable extraction may make them vulnerable over the long run.…”

We present the first-ever attempt to estimate the taxonomic diversity of climbing plants in India, following the recent APG IV classification. We used more than 100 published and unpublished sources spanning more than a century to compile the extensive list of climbers. Our study revealed that the climbing plants in India are phylogenetically diverse, representing 2624 species radiated across 585 genera and 104 spermatophyte plant families. About two-thirds of the total climbers enumerated from the present study are lianas. Scramblers, in particular, are exclusively woody, unlike twiners and tendril climbers. The diversity of climbing mechanisms varied significantly across the 104 climber families. We also present the revised list of global climbing plant families, adding significantly to the existing dataset. We found that the climber diversity data collected exclusively from the ecological inventories or the taxonomic records underestimated the actual climber diversity by a significant margin. We discuss some of the key constraints in developing a climber database and recommend a replicable model, integrating ecology and taxonomy-based enumerations for the most precise estimate of climber diversity within a defined geographical area. The baseline data generated through our research will find applications in many ecological, taxonomic, phylogenetic, and evolutionary studies on climbers.

“…Despite the lack of sufficient research, climbers and lianas (woody vines) are important forms of forest growth. However, the diversity and distribution of forest climbers and lianas around the world have been studied in several research projects, especially in Africa [1,2,6,15], in South America [7], Central America [6], and in Asia [16]. Even though climbers comprise a large percentage of the vegetation composition in the Himalayas, particularly in Pakistan, climbers have been practically disregarded in prior floristic research.…”

Climber–abiotic parameter interactions can have important ramifications for ecosystem’s functions and community dynamics, but the extent to which these abiotic factors influence the spatial distributions of climber communities in the western Himalayas is unknown. The purpose of this study was to examine the taxonomic diversity, richness, and distribution patterns of climbers in relation to abiotic variables in the Jhelum District. The data were collected from 120 random transects between 2019 and 2021, from 360 sites within triplet quadrats (1080 quadrats), and classification and ordination analyses were used to categorize the sample transects. A total of 38 climber species belonging to 25 genera and 11 families were recorded from the study area. The Convolvulaceae were the dominant family (26.32%), followed by the Apocynaceae (21.05%), and Leguminosae (15.79%). The majority of the climbers were herbaceous in nature (71.05%), followed by woody (23.68%). Based on the relative density, the most dominant species was Vicia sativa (12.74). The majority of the species flowered during the months of March–April (28.04%), followed by August–September (26.31%). Abiotic factors have a significant influence on the distribution pattern and structure of climbers in the study area. The results show that the climbers react to the biotic environment in different ways. The findings will serve as the foundation for future botanical inventories and will be crucial for understanding the biological, ecological, and economic value of climbers in forest ecosystems. This will help forest management, conservation, and ecological restoration in the Himalayas.
