Abstract: The Haveri District is located in the central part of Karnataka, acting as a transitional zone between the Western Ghats and Maidan region. The riparian zones are the most diverse, dynamic, and complex habitats on land. The present study on the riparian vegetation along the four rivers of Haveri District identified a total of 307 species belonging to 233 genera of 73 families. Out of that 231 species are indigenous belonging to 160 genera and 68 families. The remaining 76 non-native species belong to 63 genera and 27 families. The highest number of species were recorded from the Tungabhadra River (232 species), followed by the rivers Kumadwathi (181), Dharma (156), and Varada (149). Herbs are the most common among the recorded plants, with 186 species representing approximately 61% of the total flora. With 36 species, Fabaceae is the most represented family accounting for 12% of the flora. The riparian vegetation in the study area faces several threats, including habitat loss due to encroachment for agriculture, overgrazing, dumping of plastic waste, sand mining, invasive species, and tourism activities. Effective conservation measures are needed to protect the riparian zones and their plant wealth.

 

Keywords: Angiosperms, aquatic plants, conservation, Dharma, diversity, Kumadwathi, nativity, rivers, Tungabhadra, Varada.

 

INTRODUCTION

 

The term riparian is derived from the Latin word ‘riparius’, referring to the banks of rivers, ponds or lakes, along with their surrounding landscapes. Riparian zones serve as the transitional areas between the aquatic and the terrestrial environment (Zaimes et al. 2010; Betz et al. 2018). They consist of the riverbed, banks, vegetation, adjacent land and floodplains, and are crucial for maintaining the water quality in aquatic ecosystems (Maraseni & Mitchel 2016; Singh et al. 2021). Riparian zones encompass the space between flowing water at low levels and the highest watermark where vegetation is influenced by floods, elevated water tables, and soil type (González et al. 2017). The riparian vegetation has been recognized as a ‘keystone ecosystem’, since it harbors unique habitats which are highly influenced by water (Sunil et al. 2016).

In Karnataka, Kotresha & Taranath (2010) recorded 275 angiosperm species in the Varahi River basin in Udupi District. Rao et al. (2014) studied the threatened tree species of swamps and riparian habitats along different streams of Uttara Kannada and Shimoga districts.  Previous reports reveal that there was no proper documentation of floristic resources in the riparian vegetation of Haveri district and hence it was attempted in the present study. We explored the riparian flora along four rivers, namely, Dharma, Kumadwathi, Tungabhadra, and Varada, and enumerated the angiosperm species.

 

 

MATERIAL AND METHODS

 

Study area

Situated in the central part of Karnataka, the Haveri District serves as a gateway to the northern districts of the state. It is located at 14.661 N, 75.434 E (Figure 1). It comprises of eight talukas, namely: Byadagi, Haveri, Hanagal, Hirekerur, Ranebennur, Rattihalli, Savanur, and Shiggaon.

Dharma River: The river Dharma is a tributary of river Varada which flows a distance of about 32 km in northern Canara and Shimoga districts and further down it enters Haveri District near Mantagi Village in Hanagal Taluka. It drains about 625 km2 of area and traverses for about 56 km before joining the Varada River Kudala near Naregal. The canals flow in the middle of Hanagal and serve as a major water source for the surrounding agricultural lands.

Varada River: The Varada River originates near Varadamoola in Sagara Taluka of Shimoga District in Karnataka. It is one of the tributaries of the Tungabhadra River. It enters the Haveri District near Honkana Village in Hanagal Taluka. This river flows in a north-easterly direction in Hanagal Taluk and becomes a border between Haveri and Savanur. The river confluences with the Tungabhadra River at Galaganath. In its total length of 185 km, the Varada River traverses a distance of 101 km with several tributaries and drains an area of about 3,120 km2 in the Haveri District.

Kumadwathi River: This river, also known as Joradi, originates in Agastyaparvata near Humcha of Shikaripur Taluk in Shimoga District. The river flows through northern Kumsi and Shikaripur and then enters Hirekerur Taluka. It serves as the lifeline for the Madaga tank in Masur (Madagada Kenchavvana Kere). The total length of the river is about 96 km. It flows through Ranibennur and Hirekerur taluks in Haveri District for about 32 km, before joining the Tungabhadra River at Mudenur.

Tungabhadra River: The rivers Tunga and Bhadra originate in the Western Ghats flowing north-east and merging near Kudli (16 km away from Shimoga) from there the river is called Tungabhadra. It serves as a lifeline for several districts in northern Karnataka and traverses a distance of about 403 km in the geographical limits of Karnataka State. It enters the district at 14.315 N, 75.633 E near Hallur Village of Hirekerur Taluka. Confluence of River Kumadwathi at  14.494 N, 75.697 E near Mudenur village in Ranebennur Taluka and the river Varada joins at 14.929 N, 75.682 E near Galaganath. Havanur, Galaganath, and Chaudayyadanapur are important pilgrim centers in the district located on the banks of Tungabhadra.

 

Data collection and analysis

The floristic diversity along riparian zones was documented along all four rivers of the Haveri District: the Dharma, Kumadwathi, Tungabhadra, and Varada Rivers. These rivers are the major sources of water in the district (Figure 1). Random and criss-cross surveys were conducted across each study site and plant specimens were collected during different seasons, from November 2020 to August 2023. Observations made during the field visits were noted in the field notebook. The collected plant specimens were pressed and prepared herbarium vouchers following the standard methods (Jain & Rao 1977). The collected specimens were treated with a diluted solution (0.1%) of mercuric chloride (HgCl2) to prevent fungal infections. The processed herbarium specimens were deposited in the Herbarium of the Botany Department, Karnatak Science College, Dharwad (HKSCD). All the collected specimens were taxonomically identified and confirmed using relevant literature and floras, including Cooke (1958), Saldanha & Nicolson (1976), Blatter & McCann (1984), Saldanha (1984, 1996), Singh (1988), Prasad & Singh (2002), Gamble (2008), and Bhat (2014). The identified specimens were labeled with their accepted names and families as per the APG IV classification (Chase et al. 2016).

 

 

RESULTS

 

The present study documented a total of 307 species belonging to 233 genera from 73 families. Out of that 231 species belonging to 160 genera and 68 families are native to the Indian subcontinent, and remaining 76 species belonging to 63 genera and 26 families from the riparian vegetation of four rivers in the Haveri District of Karnataka, India (Table 1; Images 1–5 ). Of these, 249 species are dicots (181 native and 68 non-native) belonging to 63 families and 58 are monocots (49 native and 9 non-native) belonging to 10 families. The highest number of species were recorded from the riparian vegetation of the Tungabhadra River with 232 species belonging to 182 genera and 61 families. It includes 167 native species belonging to 146 genera & 59 families and 65 non-native species belonging to 56 genera & 22 families. This is followed by the river Kumadwathi with 181 species, 148 genera, & 52 families comprising of 134 native species, 115 genera, & 43 families and 48 non-native species belonging to 43 genera & 20 families. River Dharma has a diversity of 156 species belonging to 130 genera & 48 families represented by 120 native species belonging to 109 genera & 33 families and 36 non-natives belonging to 33 genera & 17 familes. River Varada has a floral diversity of 149 species belonging to 125 genera & four families, which comprises of 116 native species belonging to 102 genera & 43 families and 33 non-native species belonging to 26 genera & 17 families (Figure 2).      

Life form study of the collected indigenous plants shows that herbaceous flora is dominant, with 186 species (141 native and 45 non-native) contributing to about 61% of the total flora, followed by 41 shrubs (13%; 30 native and 11 non-native), 52 trees (17%; 38 native and 14 non-native), and 28 climbers (10%; 21 native and 7 non-native). (Figure 3).

With 25 native species, Fabaceae is the most represented family, accounting for 11% of the flora of the study area. Poaceae is the second largest family with 24 species (10%), followed by Asteraceae 16 species (7%), Euphorbiaceae, Acanthaceae, & Cyperaceae with 11 species each (5%), Lamiaceae with nine species (4%), Convolvulaceae eight species, and Moraceae & Apocyancaeae families with seven species each (Figure 4). 

Limnocharis flava (L.) Buchenau (Alismataceae) collected at Makanur and Somalapura villages from the riparian vegetation of the Tungabhadra River, formed a new generic report to the flora of Karnataka state (Makanur & Kotresha 2022). As for the IUCN Red List status of the collected species, Aegle marmelos (L.) Correa is classified as ‘Near Threatened’. Four endemic species were recorded during the present study: Dicliptera cuneata Nees (endemic to the Western Ghats), Acilepis dendigulensis (DC.) H.Rob. (Peninsular India), Homonoia retusa (Graham ex Wight) Müll.Arg. (Western Ghats of Karnataka), and Phyllanthus lawii J.Graham (Andhra Pradesh, Jharkhand, Karnataka, Madhya Pradesh, Tamil Nadu, and West Bengal). Alternanthera philoxeroides (Mart.) Griseb,  Mikania micrantha Kunth, and Pontederia crassipes Mart. are invasive alien aquatic species recorded. Crinum viviparum (Lam.) R.Ansari & V.J.Nair, Cryptocoryne spiralis (Retz.) Fisch. ex Wydler, Homonoia retusa (Graham ex Wight) Müll. Arg., Homonoia riparia Lour., Hydrilla verticillata (L.f.) Royle, Hygrophila auriculata (Schumach.) Heine, Ottelia alismoides (L.) Pers., Pistia stratiotes L., Pontederia vaginalis Burm.f., Rotula aquatica Lour., Tamarix ericoides Rottler, and Vallisneria spiralis L., are the aquatic plants documented during the study.

 

 

CONCLUSION

 

The riparian zones are the most diverse, dynamic, and complex habitats on Earth. The present study documented a total of 231 indigenous species belonging to 160 genera & 69 families and 76 non-native species belonging to 27 families of flowering plants along the riparian vegetation of four rivers in Haveri District, Karnataka. The highest number of species were recorded from the Tungabhadra River, with 232 species belonging to 61 families, followed by the river Kumadwathi with 181 species. The rivers Dharma and Varada showed a diversity of 156 and 149 species, respectively. Herbaceous flora is dominant in the study area, with 186 species accounting for about 61% of the total flora. Fabaceae was the predominant family, with 36 species representing 11.8% of the total flora.

The riparian vegetation in the study area is facing numerous threats. Key factors contributing to habitat loss and vegetation degradation include agricultural encroachment, overgrazing, the construction of dams and check dams, sand mining, dumping of plastic and chemical waste, invasive species, and tourism activities. Therefore, it is crucial to implement effective conservation programs to protect these vital riparian ecosystems.
