KERAGAMAN JENIS BURUNG AIR DI KAWASAN HUTAN MANGROVE PRIMER DAN HUTAN MANGROVE HASIL REBOISASI DI KABUPATEN MEMPAWAH
ABSTRACT: Waterbird is a key
species (keytone species) that can be used as one of the decisive criteria for
the condition of a wetland. This study aims to determine differences in the
types and degree of diversity of waterbird in the area of primary mangrove
forests and reforestation mangrove. This study uses the encounter rate method
(meeting level). Waterbird that found are documented and identified directly in
the field. Observations at both locations was found 17 species of waterbird are
included in 5 families (Alcedinidae, Ardeidae, Rallidae, Scolopacidae and
Sternidae). Waterbird from Sternidae family are the most found waterbird.
Diversity index of waterbird species in primary mangrove forest Desa Peniti
Kecil H'= 2.1388 is higher than reforestation mangrove Desa Sungai Bakau Kecil
H' = 1.8692, both of them included in the medium category. Based on the results
of the calculation of the t-test (2.9713> 1.97) both sites have a
significantly different level of diversity. Dominance index and evenness index
were obtained in primary mangrove forest Desa Peniti Kecil is D = 0.1360, E =
0.8338 and reforestation mangrove is D = 0.2160, E = 0.7522 indicates both
locations observations no waterbird which extremely dominates and the number of
individuals in observation locations almost spread evenly.
