A study on alien flora of Gadag District, Karnataka, India

Vascular plant diversity with special reference to invasion of alien species on the Doon University Campus, Dehradun, India

“…Additional information such as updated nomenclature of native and exotic plant species was generated through related websites like international plant name index (IPNI, 2015), the plant list (2015), encyclopedia of life (EOL, 2015), tropicos (2016) and the global biodiversity information facility (GBIF, 2015). The nativity of the invasive plants has been recorded from published literatures (Champion and Seth, 1968;Negi and Hajra, 2007;Khuroo et al, 2007;Raizada et al, 2008;Reddy, 2008;Sharma and Raghubanshi, 2008;Weber et al, 2008;Khuroo et al, 2010;Singh et al, 2010;Tewari et al, 2010;Kambhar and Kotresha, 2011;Sekar et al, 2012;Sekar, 2012;Khuroo et al, 2012;Jaryan et al, 2013;Das and Duarah, 2013;Hiremath and Sundaram, 2013;Kaur et al, 2014;Srivastava et al, 2014;Wagh and Jain, 2015;Mishra et al, 2015;Singh and Mohammed, 2015) and further categorized according to their vernacular name, English name, altitudinal range, life forms (herb, shrub, trees, grass, climber and ferns), flowering fruiting periods, plant parts (leave, root, stems, rhizomes, bark, flowers, fruits, seeds and pods). Plants were further categorized according to their economic uses such as medicinal, ornamental, edible, timber, fuel, fodder, condiments and religious.…”

“…The Tropical America contributed to the maximum percentage of species 61 (31.94%) followed by Asia (excluding Indian sub-continent) 20 (10.47%), Tropical Africa 12 (6.28%), Europe 10 (5.24%), Australia 7 (3.66%), Madagascar 5 (2.62), Eurasia 4 (2.09%), Mediteranean 2 (1.05%), Mascarene Islands 1 (0.52%), New Caledonia 1 (0.52%) and the West Indies 1 (0.52%). American continents have also contributed to majority of invasive species in other parts of India like Doon Valley and Uttarakhand (Negi and Hajra, 2007;Sekar et al, 2012), Indian Himalayan region (Sekar, 2012), Uttar Pradesh (Singh et al, 2010;Srivastava et al, 2014), Himachal Pradesh (Jaryan et al, 2013), Karnataka (Kambhar and Kotresha, 2011), Madhya Pradesh (Wagh and Jain, 2015), South Western Ghats , Darjiling Himalaya (Moktan and Das, 2013), Tamil Nadu (Narasimhan and Arisdason, 2009). The findings from literature and discussions with local inhabitants indicate that several invasive species are also used for various other purposes.…”

“…Invasion of exotic plant species might have significant adverse changes on the biodiversity and ecosystems functioning (Sharma and Raghubanshi, 2011) which further affect the environment as well as human health (Sekar, 2012). Over the years, invasion of various alien species of diverse origin has been increased in India and reported mainly from regions like Doon valley (Negi and Hajra, 2007), Kashmir Himalaya (Khuroo et al, 2007;Khuroo et al, 2010), Uttarakhand (Tewari et al, 2010), Uttar-Pradesh (Singh et al, 2010), Himachal-Pradesh (Jaryan et al, 2013), Assam (Das and Duarah, 2013), Jammu (Kaur et al, 2014), North-Eastern Uttar Pradesh (Srivastava et al, 2014), Karnataka (Kambhar and Kotresha, 2011), Madya-Pradesh (Wagh and Jain, 2015), Delhi (Mishra et al, 2015) and Haryana (Singh and Mohammed, 2015).…”

Legumes (Angiosperms: Fabaceae) of Bagalkot District, Karnataka, India

“…A preliminary list of the species belonging to Fabaceae from Bagalkot District was prepared from all the available floras, revisions and checklists (Gamble 1935;Cooke 1958;Britto 1983;Singh 1988;Sharma & Balakrishnan 1993;Prasad & Singh 2002;Prajapati 2010;Kambhar & Katrahalli 2016;Dalavi et al 2019). Herbarium studies were carried out by visiting some important herbaria namely BSI, CAL, MH, NGCPR and SUK, which was followed by extensive and intensive field tours throughout the district covering various habitats from June 2014 to January 2020.…”

“…are the dominant herbaceous legumes of the region. Kambhar & Katrahalli (2016) reported 126 species of legumes which is the dominant family from Gadag District (adjoining district of Bagalkot), while Seetharam et al (2000) in flora of Gulbarga District (region of northeastern Karnataka) also reported Fabaceae as the most dominant family. Rain shadow area and arid climatic conditions are favourable for farming several leguminous crops.…”
