Abstract	Soil and Vegetation Recovery on Abandoned Paved Roads in a Humid Tropical Rain Forest, Puerto Rico by Catherine M. Heyne Dr. Lawrence R. Walker, Examination Committee Chair Associate Professor o f Biological Sciences University of Nevada, Las Vegas I examined soil and vegetation characteristics on a 60 yr chronosequence o f abandoned paved roads in Puerto Rico. Rapid recovery obscured successional changes in soil regeneration. Littermass, bulk density, soil moisture, soil organic matter, and total Kjeldahl nitrogen reached forest levels within II yr of road abandonment despite residual pavement. Road soil pH showed a clear successional trend, and approached the more acidic forest soils within 60 yr. Pool sizes were similar to the forest by > 30 yr. Road revegetation displayed strong successional trends across the chronosequence. Vegetation on roads abandoned for > 30 yr reached a mature forest state for stem count, species richness, canopy height, and canopy cover characteristics. Basal area, understory iii Reproduced with permission of the copyright owner.

Adjacent forest conditions were die most significant in determining both soil and vegetation recovery trajectories.
