- Abstract
- Landfills are ideal locations for short-rotation forestry, tree-based bioremediation, and wildlife habitat reconstruction. However, tree survival is reduced by harsh growing conditions and poor soil quality. This study was designed to determine survival of various tree seedlings and effects of different mulch types and depths on edaphic properties, germination, and herb emergence on a closed landfill. In spring of 2002, five species of hardwood tree seedlings were planted in clustered plots, which received a mulch treatment. The status of each seedling and soil properties were recorded for two growing seasons. Survival and growth were species dependant. Fraxinus had the highest survival rate (70%) while Prunus performed the worst (7%). Leaf mulch (15 cm deep) increased organic matter and modified various edaphic properties after the second growing season. Mulch treatments did not significantly affect seed germination rates or aboveground herbaceous biomass when compared to non-mulched controls. Practical applications of these results are discussed.
