 Mount Merapi National Park (MMNP) is a natural con-servation area with the main function of preserving the diversity of plants, animals and their ecosystems. In 2010, Mount Merapi suffered a large eruption which caused damage to the forest ecosystem inside. One of the locations that suffered severe damage was at Cangkrin-gan Resort. After the eruption, the affected vegetation began to grow again. The purpose of this study is to monitor and determine the di-versity of secondary forest plants in the MMNP area. The method used was a method of path and use a point-intercept transect as the sam-pling unit. The results showed that after the eruption, the Acacia de-curens dominated at each level starting from sapling, poles and trees. Based on the results of the study showed that the eruption of Mount Merapi that occurred in 2010 resulted in a change in vegetation struc-ture in the area with the Shannon-Weiner diversity index which is still low, amounting to 1.86 for seedling, 1.32 for the sapling and 0.22 for poles. At the tree level 100% is still dominated by Acacia decurens.

The existence of cendrawasih (Paradisaea minor jobiensis Rothschild 1897) has been endangered due to destruction its habitats and wild hunting, hence conservation of its habitats is urgently needed. The objective of this study was to determine the availability of vegetation materials for creating the nests as an effort for the conservation of P. minor jobiensis in Imboriawi Forest, Barawai, Yapen Islands, Papua. Data were collected using the method of line compartment. Vegetation at seedling, sapling, pole and tree levels were measured and analyzed to determine the availability of plant species as the materials for creating bird nest. The results of vegetation analysis revealed 60 species at seedling level, 43 species at sapling level, 68 species at pole level, and 74 species at tree level with high diversity index values (H’) of 3.68, 3,32, 3,87, and 3,87 for seedling, sapling, pole, and tree levels, respectively. The results also revealed that vegetation used as a materials of nest of P. minor jobiensis in Imbowiari Forest is Bidens spilosa, Macaranga mappa, Timonius timon and Ficus septica. The four species at seedling, sapling, poles, and tree levels have low diversity index values (H’= 1) but can be used as indicators of making a nest in a sustainable way.
