Two landslide scars (slide tracks) were plot sampled one and two years after landsliding to determine plant species involved in ecesis. The study site is located in a blockfield cove on Massanutten Mountain, northern Virginia. Old growth forest, adjacent to the slide tracks, is composed primarily of hemlock (<em>Tsuga canadensis</em>) and sweet birch (<em>Betula lenta</em>). These species are the first and foremost colonizers on the slide tracks. Dendrochronological analysis shows that landsliding is frequent at the study site and this disturbance may impart non-equilibrium conditions on the forest. Seed bed characteristics, light availability, and mode of dispersal may be important factors in plant ecesis on slide tracks.
