“…So our findings are in accordance with previous reports. Nautiyal and his coworkers reported that flowering in many plant species of the alpine zone occurred after snow fall [64]. In the investigated area flowering started in the month of March for the majority of the woody plant species so our findings in this regard are in accordance with this study.…”

A comprehensive floristic survey of Kotli District, Azad Jammu and Kashmir was conducted during 2014-2016 to analyse phytodiversity and ecological characteristics of plant resources. The flora comprised of 202 plant species distributed among 71 families and 176 genera. Of these, 6 species were pteridophytes, 1 species was a gymnosperm, 159 species were dicotyledons and 36 species were monocotyledons. Based on species numbers, Asteraceae (23 Spp), Poaceae (20 Spp), Fabaceae (15 Spp), Labiatae (11 Spp), and Euphorbiaceae (07 Spp) were the leading families. Based on biological spectrum, therophytes (73 Spp., 36.14 %) were dominant followed by hemicryptophytes (19.31%), nanophanerophytes (13.37%), geophytes (10.40%), lianas (7.92%), chamaephytes (7.43%) and megaphanerophytes (5.45%). Nanophylls (36.14%), leptophylls (26.73%) and microphylls (26.24%) were the major leaf size classes. Phenological study revealed four different flowering seasons, with April the peak flowering month during which 122 species blossomed. This current study will provide essential baseline information for ecologists, taxonomists and conservationists to carry out more detailed ecological investigations and conservation management planning for the plant resources of this area.

“…The less disturbed areas were mainly dominated by Danthonia cachymeriana and the other herbaceous species had low density and high species richness. Highly grazed areas have shown low above ground biomass (Nautiyal et al 2001), and high density of the species (Singh 1999).…”

“…Klimeš (2003) also reported a small number (5-10 species) of chamaephytes within the altitude range of 4150 -4500 m a.s.l. in the alpine zone of East Ladakh (NW Himalayas), although Nautiyal et al (2001) found 18 chamaephyte species in meadows with sheep grazing of Garhwal Himalaya at 3400 -4400. At the heavily grazed North Adriatic karst pastures, the lowest number of chamaephytes was also reported (Š kornik et al 2010).…”

Alpine plants of the eastern Qinghai-Tibetan plateau (Sichuan, China) are developed under long-lasting grazing by wild and domestic yaks. Among morphological features of plants, life forms may reflect their adaptation to grazing. We studied lifeform composition of four typical communities within the alpine belt (3930 -3960 m a.s.l.) subjected to grazing of various intensity: alpine fen (heavily grazed), alpine shrub meadow (heavily grazed), Spiraea alpina thicket (grazed), and Rhododendron thicket (practically not grazed). The following morphological traits were studied: (1) life form according to Raunkiaer, (2) life form according to Serebryakov, (3) canopy structure, and (4) rate of lateral spreading. We derived lifeform spectra based on (1) the number of species per life form and (2) the cumulative abundance of species which have the same life form. One-way ANOVA and nonparametric ANOVA were run to test for significance of differences between spectra. The studied communities differed significantly by the proportion of different life forms. The main life forms are caudex and short rhizome hemicryptophytes, nonclonal species, or species with a low rate of lateral spreading. Therophytes made up 10-11% of the communities except in Rhododendron thickets, where such were absent. These life forms can indicate grazing in the study area.
