The objective of this study to evaluate the implementation of the success rate of reclamation and revegetation implemented Kitadin Embalut site. The type of research is descriptive, observation data collection and primer documents.Tool of research including: brunton compass, measuring tape, Suunto clinometer, Gauges, plastic rope. Vegetation analysis performed using a circular swath diameter of 17.8 m. The number of plots generated for each year of planting is 1 (one) with a distance of between 50-100 meters plot, the plot would be carried out observations of plant growth on the whole plant is located on the plot example, height, diameter, and canopy closure , For parameters where local species and wildlife presence also performed on this plot.The results of this study illustrate the level of success of revegetation in PT.

Canopy closure rates are in 2010.2011 and 2012 crop year was 71.2%, 60.6%, 53.4%, percentage of growth in 2010.2011 and 2012 at 88%, 77.7%, 83.6%.Based on the indicators of the success rate of growth in both diameter and height it can be concluded that the reclamation and revegetation in PT. Kitadin Embalut site considered good. In addition it should also be increased monitoring of overall plant growth so the company has a data base of all levels petumbuhan existing plants in the area PT. Kitadin Embalut site.
