InNTT province, can be found plantation forest of Teak (Tectona grandis), Ampupu (Eucalyptus urophylla) and mahoni (Swietenia macrophylla) spread on many place, in which the carbon stock potentials have not been identified yet. This research was aimed to achieve carbon stock data for teak species in mineral land plantation forest with extremely dry climate region through allometric model for improving forestry green house gases sequestration factor of two regencies in the Province. The result shows that highest carbon stock of teak forest in Kupang Regency refer to Ketterings allometric is 148,48 ton/ha, and referring to Pérez, L.D. & Kanninen allometric is 145,32 ton/ha, which occured in class III age. The lowest carbon stock refers to Ketterings allometric is 106,59 ton/ha, to Pérez, L.D.& Kanninen allometric is 107,04 ton/ha, It's occurred in age classV. The highest carbon stock of teak forest in Belu Regency refers to Ketterings allometric is 205,41 ton/ha, and refers to Pérez, L.D.& Kanninen allometric is 203,43 ton/ha, which occured in age class VIII.

Both, Ketterings and Pérez, L.D. & Kanninen allometric gives the near same results. The trend of Carbon sink among age class of teak forest area in Kupang regency could be estimated and drawn by a very low slope line, and just the same in every class age wether refers to Ketterinsg or Pérez, L.D.&Kanninen allometric.

The management of cendana had been passing many time and period, which it has having good and bad experience depending on several factors. Some of these are regional regulation which did not support the efforts for developing cendana plantation. This research was aimed to know cendana crown stratum and competition index especially in private land. Achieving information and data on cendana habitat for supporting the implementation of Cendana Master Plan in NTT Province become the targets of the research. Metodology of the research is descriptive quantitative which based on directly field survey. Data collection was conducted by three ways, which were interviewed with the stakeholders, direct survey and desk studied of secondary data. The result shows that Santalum album trees tend to grow at stratum 1 and 2 of the overall plantation in one area. And the average of competition index of Santalum plantation in TTS regency is 0,18; in TTU regency is 0,07; and Belu regency is 0,1.

Productivity needs to be increased due to the demand. One method which could be done is by tree improvement. Tree improvement have to be conducted in efforts to increase cajuput oil productivity. This research was aimed to increase genetic quality using seed produced from the first progeny trial. The research was carried out in Banamlaat research station, Kefamenanu, District TTU, Province NTT. The longterm target is to establish F2 progeny trial seedling seed orchard of Melaleuca cajuputi subsp. cajuputi. Plot design used was Incomplete Block Design, with 6 replicates, 54 seedlots and 3 treeplot. The planting distance are 3 m x 1.5 m. The result showed that in the first year (end of nursery/6 month), the growth varied. The best ten family in height growth are family number 21, 51, 43, 42, 12, 52, 11, 50, 31, 1. The best ten family in diameter growth are, 11, 43, 21, 1, 32, 51, 42, 46, 45, 19. The best ten family in leaves growth are 1, 50, 32, 53, 11, 21, 30, 12, 24, 43. Four families consist to appear as the best ten in 3 variables (height, diameter, leaves growth).These are family 21, 43, 11, 1. These families are considered as the best families in the next step of test in the field.

People utilize it by cutting down the growing productive trees, causing the sustainability of gewang becomes threatened. Province of Nusa Tenggara Timur (NTT) is natural habitat for gewang distribution. On the other hand, stands have ability or function as carbon absorber and sinker also. Because of this, the existence and regeneration process should be guarded as this function is in line with the efforts to increase carbon stock of savanna forest in NTT. Information of carbon sink in trees became important, because of with this information could be understood the most feasible size/dimension of gewang to be harvested. Up to now there is no allometric equation which is specifically developed to estimate carbon stock potential on gewang's savanna . In order to provide data using of accuracy level 3 Tier 3 , carbon stock estimation was done by estimating biomass and carbon, modell for specific species and site.

Related to the provision of data in tier 3, the estimation of carbon stocks begins with the estimation of biomass using species and site specific model. This study aims to reduce uncertainty in estimating carbon sink in Eucalyptus alba savanna forest and to improve its accuracy. The study was conducted in TTURegency,NTT Province (West Timor). It estimated tree biomass by direct measurement using destructive sampling. Fifteen trees from five different diameter classes were cut as sample trees. Whole stem volume was measured. Wet weight of all parts of the branches, leaves and twig weighed. Then samples were taken from each component to be dried in the laboratory to determine the biomass dry weight. The allometric equations were then developed using the best equation of regression. The results showed the best allometric equation for stem biomass is y = 7.725e , leaf biomass is y = 0.010x , branch biomass is y = 0.005x , and for twig is y=0.015x .
