Abstract

Biodiversity is a common means of ecosystem resiliency; as a diversified community can withstand in
a small to medium scale disturbance or can build back better by using its own resources (species). Two
adjacent Eco park eg. Durga Sagor Eco Park and Planet Park of Barisal in the district of Barisal, Bangladesh
have managed terrestrial ecosystem with a lot of plant diversity. This study focuses on to formulate a
diversity index and assessing ecosystem resiliency by using the index of two different ecosystems. For
conducting this research visual screening is conducted by the authors, secondary data sources like annual
report of Park authority, books, journals etc. have been used respectively. The major findings of this study
are that Durga sagor ecosystem has greater biodiversity than Planet Park ecosystem. The Shannon Index
and Shimpson Index of Durga sagor and Planet Park is 2.71, 2.62 and 0.14, 0.13 respectively. Evenness of
two adjacent ecosystems is 0.80 and 0.77. Finally the results indicate that Durga sagor ecosystem is more
resilient than planet park ecosystem as its biodiversity is greater than Planet Park. In case of any natural
disturbance (natural disaster) Durga sagor ecosystem will withstand more time than Planet Park ecosystem.
