ABSTRACT

PRIHATNO SINAGA. Bird Species Diversity Based on The Strata Utilization
of Vertical Vegetation in Mangrove Forest of Jaring Halus Village. Under
Supervised by Pindi Patana and Erni Jumilawaty.
One type of ecosystems that used by birds is the mangrove forest. The
existence of birds in an ecosystem can indicate whether an ecosystem is good or
not. This study aims to identify species of birds as well as calculate species
diversity, evenness type, and bird species dominance based on vertical strata of
vegetation in mangrove forest of Jaring Halus Village. This research was
conducted in mangrove forest of Jaring Halus Village. The method used is Point
count method or IPA (Indices Point of Abundance).
The results showed that in the mangrove forest of Jaring Halus Village
there are 8 species of birds that consist of 6 families with the number of
individuals are 57 with the number of individuals on each strata- that is in strata I
are 12 individuals, strata II are 20 individuals, and strata III are 25 individuals.
The index value of species diversity in each strata that is in the strata I is 1.356 in
the medium category, the strata II amounted to 1.364 in the medium category, and
the strata III is 1.769 in the medium category. The value of the evenness index of

each strata is in strata I of 0.978 in uneven category, in strata II of 0.984 in
uneven category, and in strata III of 0.85 in uneven category. The highest type of
dominance is found in Strata III with 36% by bird species Nectariniacalcostetha.
