Investigation of Species Diversity of Birds in Bisheh Dalan Boroujerd Wetland

Abstract

Introduction: Protecting wetlands and the life in them requires recognizing the
biodiversity of these ecosystems. waterfowl and shorebirds that are ecologically
dependent on wetlands are used as environmental in dicators. Bishe Dalan wetland with
an area of 913.5 hectares is one of the largest wetlands in Lorestan province, which is
located in the south of Boroujerd city and on the edge of Silakhor plain.
Materials & Methods: In this study, species diversity indices (Shannon-Wiener and
Simpson photos), species uniformity (Smith-Wilson indices and Simpson dominance)
were used to study the species diversity of Bisheh Dalan (2017-2020).
Results: In Bisheh Dalan wetland, 9 Orders out of 22 Orders, 13 Families out of 78
Families and 48 Species out of 545 Species Identified in Iran, Census and registration,
which are 40.09 percent of the order, 16.66 percent of the family and about 8 percent of
Iranian bird species have lived in Bishe Dalan wetland. the results of bird species
diversity study in Bishe Dalan wetland showed that 67.90 percent of the bird abundance
of three species of green duck (Anas platyrhynchos), Common fox (Fulica atra) and
Gypsy rooster (Vanellus vanellus) and about 41.66 percent of birds in the situation is
protected and endangered.
Conclusion: In terms of species diversity and species uniformity, 2019 had the highest
rate of indicators. in general, the trend of heterogeneity and uniformity indices in the
forest wetland is a sinusoidal corridor.
