Mason's research is well summarized in an online entry from University of California: In Memoriam, 1994: "Although a self-professed taxonomist, Mason was always more interested in the causes underlying plant evolution and distribution, both past and present, than he was in details of classification. His efforts shifted more and more to what he termed 'plant geography' to distinguish it from the then mainstream plant ecology, which was for many years dominated by the ideas and overblown terminology of F. E. Clements. Mason stressed the direct relationship of environmental factors to the varied tolerance capacities of the plants comprising a given community, and rejected the almost organismal interpretation of 'associations,' 'climaxes,' and other phytosociological abstractions." Mason was an especially respected teacher, and served as president of several Western U. S. and national scientific societies.
