【 摘 要 】

Food availability affect the orangutan activities, including activities to make nests. This study was conducted to determine 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. Multi linear regression was used in this study to determine the relation and correlation between phenology and the presence of orangutan nests on a track that has been created. It took over 6 months (March - August 2015). There were 15 orangutan nests found on the track during the study. The equation model was : = 27,649 -0,011X1-0,104X2-0,056X3, and there was no significant differences (sig >0,05). The value of R2was 70,3%. It means that all predictors simultaneously explain 70,3% of the presence of orangutan's nest, and there is an expected predictors that may be the most affect on nest presence. The season or the intensity of rain may consider as an expected predictor.
