Vision: The Women in Arboriculture committee (WIA) seeks to empower women and foster gender equality throughout all levels of the tree care industry.

Mission: WIA works toward making our vision a reality in three ways:

1. WIA brings the tree care industry together to identify the challenges women face and discuss solutions that increase recruitment, hiring, and advancement of women in the industry.

2. WIA hosts, coordinates, and obtains funding for women-centric arboricultural events that focus on teaching skills that can be used to enhance careers while facilitating professional networking.

3. WIA increases the representation of women in the tree care industry by producing informational materials that feature them in a variety of tree care roles.
