Assessment of Soil Properties and Tree Performance on Fountain Avenue and Pennsylvania Avenue Landfills in New York City
Revegetating closed landfills offer a unique opportunity to transfer underutilized lands into green spaces which are on high demand in large cities with dense urban population. Planting woody vegetation on landfills could also help improve wildlife habitats, store carbon dioxide, reduce stormwater runoff, and provide public amenity. Unfortunately, previous studies showed that ecological restoration of landfills is challenging due to many limiting factors such as soil compaction, acidification, and lack of nutrient. More detailed, long term studies are required to develop optimal ecological restoration protocols. This project assesses soil quality and tree performance of two large and capped landfills in New York City. The landfill soil generally has a poor condition with some pH lower than optimum for trees, low levels of P, K, N, nitrate-N, and high level of Fe. Quercus, Pinus, and Junipercus are the most prevalent genus. Naturally occurring species especially Salix sp. also has a high coverage. Statistical analysis of tree density shows a medium strong positive correlation with plant-available Fe and negative correlation with plant-available Mg. The results show that nutrient levels of landfill soil could be important for the success of vegetation.
