text: Rowland (1978) postulates that perhaps it would be more accurate to consider the Joshua tree as a component of other grassland and shrub communities regardless of density, because [it] is common in some areas and uncommon in others and trees other than the Joshua are often present. Sawyer and Wolf (1995) also refer to (Phillips et al 1980) who explain that there are stands of Joshua trees in Joshua Tree National Park that are considered to be a Joshua tree woodland series but they contain an abundance of other trees such as California juniper or in some cases Desert Scrub Oak or Pinyon pine.
