| dc.description.abstract | MARINA OKTAVIANI BR KARO: Correlation Phenology Tree with Nest Amount
Sumatran Orangutan (Pongo abelii) In Primary Forest Resort Sei Betung Gunung
Leuser National Park, under the supervision of PINDI PATANA and KANSIH
SRI HARTINI.
Phenology is the period of the phases that occur naturally in plants, ranging from
phase to phase the young leaves of fruit. Food availability affect the orangutan
activities, including activities to make nests. This study was conducted to
determine how the correlation between the phenology of trees with the number of
nests made by orangutans in primary forest Resort Sei Betung, Gunung Leuser
National Park. Zweifel method used in this study to determine the estimated
productivity of trees and observations orangutan nests on a track that has been
created. This study was conducted over 6 months (March - August 2015).
The results showed phenological observations of trees in relatively low due
to the dry season is long enough and the weather is hot. There are 837 trees feed
on track with the kind of observation at most that Polyalthia sumatrana and non
feed 730 trees with most types of Aglaia edulis. Found 15 orangutan nests on the
track during the study performed. Tree phenology correlated very weak and
insignificant with nesting by orangutans. | en_US |
