Logic and Effectiveness of Urban Tree Preservation: A Comparative Case Study of Charlotte and San Antonio

While most U.S. cities have a tree protection policy, the subsequent impact on the reduction of canopy loss is unclear. To rectify this, I utilize a theoretically grounded framework of influence comprised of clear identification of the problem/public support, adequate resources, and sound policy logic. This is then tested in a comparative case study of Charlotte, North Carolina, and San Antonio, Texas. While Charlotte benefits from public recognition of the problem and adequate resources, its regulations are weak, lacking a logical connection to aspirational outcomes. San Antonio's regulations are stronger, but combined with weaker problem identification and resources. Through quantitative and qualitative assessments, I find that San Antonio's strict regulations may have stabilized loss rates, while Charlotte's weaker rules have not. Results highlight the importance of policy logic over other commonly suggested determinants of natural resource protection.
