Slope vegetation of cut and fill slopes on expressway, which have been seeded, make secondly succession. Phytosociological survey of the succession is important for the management of slope vegetation. Unfortunately, almost all of the techniques we are familiar with are time-consuming, involving plot studies. In view of the immediate need for information on the large roadside areas still unstudied in the expressways, the author thought it desirableto develop an analysis technique based on quick reconnaissance methods. A rapid technique makes it possible to visit a greater number of stands, thereby sampling a greater range of variability in a larger geographic area in less time. And the many data accumulated in a rapid survey necessitates the assistance of computers in data analysis.<BR>The author made a case study on Meishin expressway (189, 8km), Tomei expressway (346.4km), and Chuo expressway (123.7km).<BR>Selection of locations or stands for sampling was done regularly in each kilometric post K.P.. Size of sampling area is about 50-100m2, where is a enough area for the sampling plot of grassland and scrub communities. Collection of data, i.e. deciding which data to record, is the important thing, for this is a quick reconnaissance method. For the quick survey, exact location of plot boundaries or measurement of vegetation or site factors was not practiced. Most of the data recorded were based on ocular estimation.<BR>The number of data was 577 plots. The first job in analyzing the data was to punch cards for computer analysis. The dominant species of each ways were calculated, and the relation between the vegetation types of each successional stages and the site factors was analysed.<BR>Then the author discussed the applications and limitations of the reconnaissance method.<BR>This reconnaissance method, however, requires the establishment and sampling of more detailed analytic plots.
