Abstract

 

In wetland, the disturbances that influence the distributional pattern of plant community along the land-water interface are thought to be driven by spatial variations in water regime. Tropical wetlands are among the most productive ecosystems, containing unique aquatic and terrestrial communities. In the lacustrine wetlands a distinct zonation from aquatic to terrestrial vegetation exists. This study was aimed to investigate the effect of water regime in plant species composition and richness in wetlands of Tal-Kandala, north-eastern Uttar Pradesh, India. The analysis of data shows that highly disturbed communities were poor in species richness while communities with moderate disturbances were comparatively richer. The deep-water community showed low species richness due to various disturbance regimes and homogeneity of the aquatic habitats where most of the species are highly specific to habitat conditions. The richness of species in periodically flooded lowland community was considerably greater due to invasion by weeds from the surrounding agricultural field. Our results indicate that shallow water community showed negative relationship between species frequency and abundance while the rest five communities were positively correlated. This study is a step towards a better understanding of plant communities within the landscape; and provides basic information to manage the conservation of wetland vegetation.

 

Key words: Tal-Kandala, water regime, phytosociology, plant community.
