Historic land use development in Phoenix has impacted the city's ecologically valuable open spaces. This dissertation studies the possible effect of landscape change between 1968 and 1998 on the South Mountain Preserve (SMP) and Phoenix Mountains Preserve (PMP). Recommendations for a future development pattern are provided. Three principal analyses are employed: (1) matrix utility analysis; (2) isolation analysis; and (3) connectivity analysis. Black and white aerial photographs of the study area were used for the investigation in Geographic Information Systems (GIS). The results indicate: (1) a decline in matrix utility value of 21.65% for SMP, and 36.50% for PMP, (2) an increase in isolation value of 1.28% for SMP, and 285% for PMP, and (3) a decline in the overall matrix connectivity value of 67.8%. The conclusions of the research are that the ecological values of the mountain preserves may change due to the historic land use pattern: (1) the areas surrounding the mountain preserves were occupied by environmentally less sensitive land use types, (2) existing open space patches became smaller and more isolated due to increasing fragmentation, (3) connectivity between the open space patches was paralyzed as the detrimental effect of urban sprawl, and (4) PMP experienced more decline in the ecological values than SMP. Recommendations primarily include: (1) encouraging more environmentally compatible land uses around the preserves, (2) creating buffer zones, (3) considering both content and the context of the preserve in management actions, (4) developing effective land acquisition and zoning plans, (5) unifying preservation efforts of different local and government agencies, (6) improving connectivity with other open-space systems, and (7) maintaining near-natural levels of biodiversity in the urban matrix.
