What is a Professional Interest Group? (Formerly Called Working Groups)

The objectives of most ASHS Professional Interest Groups include the following:

  • To promote interaction between and among the research, extension, teaching, and industry components of horticultural science;
  • To provide a forum for the development, discussion, exchange, sharing, or dissemination of ideas, information, or materials via approved Workshops, Symposia, contributed paper sessions, discussion groups, business meetings, field trips, regional and national meetings;
  • To promote, encourage, facilitate, or coordinate basic and applied research and education by identifying critical needs, developing methods and procedures, or preparing proposals;
  • To promote liaison or good working relationships with other organizations with similar interests;
  • To educate the public
  • To encourage recruitment of young scientists; and
  • To recognize outstanding contributions.
