Each plant species in a community will have its own distribution pattern. This pattern can have similarities with other species but may not be entirely the same. Dramaga Research Forest according to government administration is included in the area of ​​Situ Gede Village and Bubulak Village, West Bogor District, Bogor Municipality. From 1956 to 1998 in the Dramaga Research Forest, 130 species of plants were introduced. These plants have no known spatial distribution pattern. Therefore, the purpose of this research is to be a preliminary study to determine the spatial distribution pattern of several plants in the Dramaga Research Forest. The method used is to use a sample unit of observation. There are four categories of vegetation grouping and measuring plot area, namely trees, pencang, and seedlings. From the sample unit data, it will then be analyzed using the variance ratio method and the index method. From the three methods above, the distribution pattern of several tree species in the Dramaga Research Forest was obtained based on calculations using the variance ratio method, dispersion index, clumping index generally spread in groups. The distribution pattern is clustered due to the tendency of the species to occupy a preferred habitat. Calculation using the morisita index, there are several species that spread uniformly. The difference is due to the method of variance ratio, dispersion index, clumping index using the average value and variance value, while the morisita index uses individuals from each type. The uniform distribution pattern occurs because of competition between species
