The Fraser Valley of British Columbia boasts a rich diversity of plants and trees that have been used by the Stó:lō people for food, medicinal purposes and for various other utilitarian or ritual purposes. Berries, roots and shoots encompass the bulk of the botanical materials that have been used in the day-to-day lives of the peoples of the Southern region of the Northwest Coast. People of all ages have been involved in all manner of plant collection, from berry picking to bark stripping.
The use of plants also includes the management of these resources, from the replanting of bulbs to the deliberate pruning of plants to maximize the following season's harvest. Perennial plants, which would return the following harvest season, were well cared for in hopes that these activities would result in a greater harvest volume the next season. Land management was an important part of Stó:lō life.
