Abstract: | In the urban landscapes, scientific understanding of the roadside vegetation is a prerequisite for better planning and designing of sustainable cities. The Srinagar city, located in the Indian Himalayas, represents an urban biodiversity hotspot but the information about the floristic diversity especially along its roadsides is lacking. In order to fill this knowledge gap, the present study using field-based plant collection surveys was undertaken to investigate the floristic diversity growing along the roadsides of Srinagar. A total of 206 vascular plant species were recorded with the proportion of alien species relatively higher (52%) than the native species (48%). Of the 108 alien species, 24 were invasive, 44 naturalized, 12 casual and 23 were cultivated. Most of the species were herbs (165 spp.) and the majority of these were wild growing (155 spp.). Based on Raunkiaer’s lifeform characterization, therophytes (94 spp.) were the most dominant. Interestingly, the therophytes harboured the highest number of alien species (50 spp.), followed by phanerophytes (29 spp.). There was significant difference between the floristic spectrum obtained during the present study and the normal Raunkiaer’s spectrum. The present study provides policy-relevant baseline data which can guide the urban planners to develop sustainable planning in this Himalayan city. |
