Abstract
Riparian zones are ecologically significant
areas that support biodiversity, regulate hydrological processes, and provide
essential ecosystem services. This study investigates the floristic diversity
and vegetation dynamics along the Vartu River in Gujarat, focusing on seasonal
variations in species composition and edaphic factors. Data were collected from
three riparian zones—Fatana (RZ1), Ranparda (RZ2), and Zinavari (RZ3)—across
pre-monsoon and post-monsoon periods. A total of 43 plant species were
recorded, with a notable increase in species richness post-monsoon. The
post-monsoon period exhibited a rise in hydrophilic species such as Echinochloa
crus-galli and Alternanthera sessilis, while drought-resistant
species like Parthenium hysterophorus dominated pre-monsoon. Alpha
diversity indices showed a significant improvement in species richness (Taxa S
increased from 12–13 in pre-monsoon to 20–24 in post-monsoon) and Shannon index
values, indicating enhanced biodiversity post-monsoon. Beta diversity indices
reflected increased species turnover, with Cody’s index rising from 14.5 to 26.
Soil parameters, including moisture content (+61.29% in RZ1) and pH (-16.67% in
RZ3), also exhibited significant seasonal variations. These findings underscore
the role of monsoonal hydrology in shaping riparian vegetation dynamics, emphasizing
the need for conservation strategies that account for seasonal ecological
fluctuations.
