Abstract

Harapan rainforest situated in South Sumatera is a restoration area of PT REKI company that highly susceptible to land conversion. The problem faced in the effort of restoration is the restorated area that is too large and has not been tested any silvicultural techniques. The condition of land cover is the basic information that could be used as a reference in the preparation of restoration strategy. The study aimed to determine the level of damage, the condition of the ecosystem, appropriate silvicultural techniques, and plant species restoration priorities. The used methods were analysis of vegetation in 4 typologies (secondary forest, old shrub, young shurb, former akasia plantations), and the analysis of Normalized Difference Vegetation Index (NDVI). The results showed that the correlation between density value (y) and NDVI (x) was: y = -136.35+425.46x, R2 (0.89). The order of  area with the level of damage from the lowest to the highest were: the typology of secondary forest, old shurb, young shrub, and former akasia plantation, respectively. The typology of secondary forests had the highest value of diversity, richness, and evenness  (H’>3, Dmg>5, and E>0.6). Relationship between former akasia plantations typology and another tipologies was not germane (euclidean distance> 3.31), and the relationship between seedling and trees in all typologies (with the exception of former akasia plantations) was  very high  (r> 0.9). Silvicultural techniques that could be done include eradicating A. mangium in the former akasia plantation and planting in the all typologies with the exception of secondary forest. The plants that could be used for restoration are Macaranga sp., K.malaccensis,  Nephelium sp., P.gutta, H.mengarawan, S.leprosula.

Abstract

Failure in degraded forest rehabilitation was caused by using chosen species without pay attantion on site characterictics. Species selection by looking at site limiting factor, will increase success in degraded forest rehabilitation. This research aims to study the influence of physical and chemical soil properties on growth of Shorea leprosula Miq, Shorea palembanica Miq, dan Shorea mecisopteryx. Data was analyzed using multiple linear regression analysis with mean annual increment (MAI) of height and diameter as dependent variable and soil properties as independent variable. The results showed that growth increment of S.palembanica was the most species that influnced by soil perperties with R2 adjusted value for MAI-diameter and MAI-height repectively, 0.946 and 0.674 whereas others two Shorea have R2 adjusted value < 0.5. The research also showed that available P content was the limiting factor of the three species. There was a difference of each species in respond to the available P content. MAI-height on S. mecisopteryx and MAI-diameter and MAI-height on S. pelambanica will increase in line with decreasing available P content while S. leprosula required P available increasing in order to increase of MAI-diameter. This indicates that each species have specific response on certain soil properties content.

Abstract

Natural regeneration of Dipterocarpaceae depends on the availability of the mother trees, flowering cycle, and favorable site conditions. Potential seed of Shorea leprosula in Haurbentes Forest Research, Jasinga District, Bogor, should be supported with sufficient regeneration ability. This research aims to identify the condition of regeneration of Shorea leprosula, environmental conditions and soil conditions that support for the sustainability of the S. leprosula regeneration in Haurbentes Forest Research, Jasinga, Bogor district. The results of the vegetation analysis showed that condition of the forest regeneration S. leprosula in KHDTK Haurbentes quite sufficient for seedling which are found quite a lot and dominating on every block of observations. However, seedlings are experiencing obstacles in resuming its growth to the level of sapling and poles. This can be seen by the existence of another species that dominates at the level of the sapling and the least amount of poles found. The existence of competition with other species and lack of space grows to regeneration due to the dominance of mature trees suspected that caused the regeneration S. leprosula on blocks of thisplant disturbed. Environmental conditions and soil conditions sufficiently support growth of S. leprosula. However, the lack of light intensity that goes into the stands is suspected to be one of the barriers to regeneration of S. leprosula.

Abstract

Shorea leprosula Miq is a Dipterocarps forest plantation that has the prospect of being developed because it is a fast-growing species with high economic value. Given its commercial importance, this study was conducted to analyze the effect of slope class and slope direction on growth. Data were collected using the census method on S.leprosula stands with a spacing of 2m x 2m and 4m x 8m. The direction of the slope is determined based on the configuration of the slope according to the cardinal directions, while the slope of the land is determined based on the classification of the slope class of the land. The results showed that the slope class, slope direction, and the interaction between factors had a significant effect on the growth of S.leprosula. The interaction between the slope class and the direction of the slope produces the highest average annual increment of diameter in the flat slope class with the direction of the slope facing north, which is 1.79 m / year while the highest annual increment of the total average height is in the very steep slope class with to the slope facing to the north at 0.82 m / year.

Abstract

Shorea leprosula is one of the tree species within Dipterocarpaceae family which is a major source for timber production. The species has been planted massively in Gunung Dahu Research Forest (GDRF) in Leuwiliang- Bogor. Gunung Dahu Research Forest is a man-made dipterocarp forest which has varying slope class, topoghraphy and canopy cover. Furthermore, Natural regeneration is an important ecological factor in assessing the ability of forest regeneration, including in a plantation forest. Therefore, it is necessary to know the effect of slope and canopy cover on the regeneration of S. leprosula in order to characterize what factors support and constraint the naturally regenerating forest of Gunung Dahu Research Forest. Regeneration capacity of the species was observed in purposive plots which have been recorded for their flowering events. Seedlings were grouped into seedlings, and saplings. It was measured by census method in every slopes. Meanwhile, Variable observed included, number of available seedling at each slope category slope with its canopy cover, height and diameter of seedlings, and litter thickness. Regeneration capacity of the species was observed in purposive plots which had been recorded for their flowering events. Seedlings and saplings were taken using the census method. The results show that flat slope with shady canopy cover has the highest capacity of seedlings and the best growth. The uneven distribution of height and diameter indicates the need for silviculture action; such as, maintenance.

Abstract

Luasan hutan di Indonesia yang semakin berkurang akibat deforestasi memerlukan pengelolaan hutan lestari. Shorea stenoptera Burck merupakan salah satu jenis endemik tanaman kehutanan di Borneo. IUCN menyatakan bahwa jenis tersebut termasuk ke dalam status hampir terancam (Near Threatened). Tujuan penelitian ini adalah menganalisis komposisi jenis, struktur tegakan, dan regenerasi alami tegakan S. stenoptera, serta mengidentifikasi pengaruh aspek biofisik terhadap keragaan regenerasi alami S. stenoptera di KHDTK Haurbentes, Kabupaten Bogor, Jawa Barat. Metode yang digunakan adalah analisis vegetasi dengan membangun petak pengamatan sebanyak 5 petak. Hasil penelitian menunjukkan bahwa jenis S. stenoptera mendominasi pada setiap tingkat pertumbuhan pada petak pengamatan S. stenoptera. Struktur tegakan menunjukkan kurva J terbalik. Hal tersebut mengindikasikan tegakan S. stenoptera mengalami perubahan formasi ke hutan alam. Regenerasi S. stenoptera menunjukkan regenerasi normal dengan kerapatan individu semakin berkurang seiring bertambahnya kelas diameter. Aspek biofisik seperti kelerengan dan elevasi sangat memengaruhi pertumbuhan S. stenoptera.

Abstract

Zona tradisional Taman Nasional Gunung Halimun Salak (TNGHS) merupakan zona yang sangat dimanfaatkan oleh masyarakat setempat untuk memenuhi kebutuhan sehari-hari dengan memanfaatkan sumber daya hutan bukan kayu dan menerapkan sistem agroforestri dengan komoditas utama poh-pohan (Pilea melastomoides). Pemantauan hutan di zona tradisional TNGHS sangat penting dilakukan sebagai bagian dari pengelolaan hutan lestari dan realisasi dukungan program Forestry And Other Land Use (FOLU) Net Sink Indonesia 2030. Penelitian ini bertujuan menganalisis kerapatan vegetasi berdasarkan nilai NDVI; menganalisis tingkat keanekaragaman jenis tumbuhan dan struktur tegakan di zona tradisional TNGHS. Selanjutnya dilakukan pendataan keanekaragaman jenis tumbuhan di kawasan tersebut berdasarkan nilai NDVI kerapatan vegetasi. Nilai NDVI diperoleh menjadi tiga kelas yang memiliki kondisi lahan yang berbeda. Nilai kelas 1 berkisar antara 0,147 sampai 0,273 memiliki kerapatan vegetasi yang rendah. Kelas 2 dari 0,273 sampai 0,319 memiliki kerapatan vegetasi sedang. Sedangkan kelas 3 memiliki kerapatan vegetasi tinggi dengan nilai 0,319 hingga 0,433. Keanekaragaman jenis tumbuhan memiliki 60 jenis yang berbeda dari total tiga kelas. Kerapatan semai lebih rendah dari pancang, namun pada tingkat tiang dan pohon semakin menurun yang menandakan struktur tegakan seimbang. Tingkat semai yang rendah disebabkan oleh terhalangnya pertumbuhan semai akibat pembersihan yang dilakukan oleh masyarakat setempat untuk persiapan penanaman tumbuhan bawah karena masyarakat lebih memilih menanam tumbuhan bawah yang lebih cepat panen dibandingkan semai tumbuhan berkayu.
