DescriptionAs the population of New Jersey continues to grow and more areas are classified as developed or urban areas, more people will be affected by the consequences of living in an urban environment. These consequences include but are not limited to increased heat stress, greater water regimes, and air pollution. The inclusion of green spaces, particularly those which include trees, have been shown to help mitigate these negative consequences. These are called ecosystem services. Three common growing sites, lawns, strips, and pits have been identified within the urban context. My research focuses on street trees and the roles they play in managing ecosystem services over time based on the growing site. In Chapter 1, I established the maximum service age of 9 species based on site type and established the growth rate of the diameter at breast height (DBH). In this chapter I found that maximum service life did vary between site types of the same species. Using the Chapman-Richards growth model I established the growth rate of both basal area and DBH based on species and site type. Chapter 2 analyses the allometric relationship between crown volume and DBH of 10 species based on site type. By using photography and scaling software I estimated crown volumes. By implementing model selection, I chose a quadratic model to assess the relationship between the two variables. I found crown volume to vary between the site types and estimated the parameters for the proposed model. In chapter 3 I assessed the relationship between DBH with leaf area index (LAI) and total leaf area. In this chapter I measured DBH, estimated LAI with a LAI2200C, and calculated total leaf area based on ground area and LAI. Following model selection I estimated the parameters of the ln-ln model. LAI was found to differ between the site types. In chapter 4 I converted the previous models from chapters 2 and 3 to calculate crown volume, LAI, and total leaf area based on age rather than DBH, by substituting for the Chapman-Richards growth model and the estimated parameters. These conversions were then used to estimate ecosystem services at a given age rather than morphological size and models to project ecosystem service over time were generated.
