Plant species composition, calculated leaf masses and estimated biogenic emissions of urban landscape types from a field survey in Phoenix, Arizona

Vegetation in the Phoenix, Arizona, metropolitan area was surveyed using a modified stratified random sampling design to identify plant species and to measure foliar volumes for species-specific calculation of leaf mass. [The authors] identified the genus and species and measured the crown dimensions of plants located in a park and parking lot, and in three types of urban landscapes: flood-irrigated, mesic and xeric.... Plant species and leaf mass data were used to estimate relative contributions from each landscape type of the biogenic volatile organic compounds isoprene and monoterpenes. Results from this study have implications for future plant surveys taken for biogenic emissions inventory development, and for plant species selection for urban landscapes, especially large-scale tree planting programs.
