  • Funding the salaries and benefits of the two UW Botanic Gardens horticulturists who care for the Pacific Connections Garden in the Arboretum.
  • Funding temporary gardeners assigned to special projects, such as the restoration of the Lake Washington Boulevard Corridor.
  • Coordinating the Garden Stewards program, which recruits and trains volunteers to assist horticulture staff with weeding, mulching, and other tasks.
  • Coordinating the Corporate and Group Service Program, which recruits volunteers from local businesses and community groups to participate in weeding and mulching work parties.
