  1. Locations listed by latitude, from North to South
  2. Table and additional data from Wood et al. (1998): precipitation data for the United States was obtained from NOAA (1986). For Mexico, from Garcia de Miranda et al. (1980). Mean annual temperature and minimum temperatures were obtained from the USDA Plant Hardiness Zone Map
  3. aRainfall is based in the period from 1 March to 31 August, when foliage would be susceptible across the geographic range
