An in-depth understanding of what constitutes success is needed in order to assess current management practices and improve to ensure a more stable urban canopy trajectory in the future. This dissertation is comprised of three studies that investigate three discrete time pieces in the urban forest in order to determine and measure their success. The early transplant survival study found after two years post-transplant, urban trees had a 91.4% survival, whereas the survival declines 8-9 years post-transplant to 75.8%. Trees had the lowest survival in downtown areas and increasing survival as a residential gradient was reached. The parking lot study examined trees approximately 20 years post-transplant in order to determine a size reduction based on amount of apparent available soil. Tree Diameter Breast Height (DBH) was fond to be a useful predictor of tree canopy area. There was a reduction in canopy area seen across all five species measured as apparent available soil decreased. The maximum size study linked terminal size (stem diameter) to site type based on apparent available soil when trees were grouped into categories based on their published height expectations (small, medium, large). Maximum height was different in all three plating site types, irrespective of size class. Overall a reduced planting space resulted in a reduced maximum size, which serves as service endpoint for managers.
