We describe natural revegetation dynamics on landslides that occurred in 1948 and 1959 in Franconia Notch, New Hampshire, U.S.A. Analysis of aerial photographs from 1958, 1978, and 1996 indicate that the rate of revegetation of the landslide surface decreased over time, probably because of early saturation of easily colonized sites. In the 1948 landslide, we found that width and slope steepness within the landslide influenced the revegetation rate, while elevation did not. On the 1959 landslide, none of the tested factors were significantly correlated with vegetation recovery. Recolonization of narrow erosional zones tended to occur from the landslide edges inward; recolonization of wider erosional zones also occurred outward from islands of vegetation within the landslide. Floristic inventories were conducted in 1956 and 1996 using the point-centered quarter method and fixed plots of 1 m2 and were processed using cluster analysis, resulting in a grouping of the 1956 and 1996 plots into four and five clusters, respectively. The 1956 clusters consisted of exclusively herbaceous vegetation (zones with greater erosion) or prevalently shrub-arboreal vegetation, with Betula cordifolia Regel. dominant at high elevation and Betula papyrifera Marsh. and Betula alleghaniensis Britton dominant at low to middle elevation. The 1996 vegetation was characterized by prevalence of arboreal canopy made up of differing proportions of birch species, which varied with elevation.Key words: disturbance, floristic composition, regeneration, recolonization, succession, White Mountain National Forest.
