Plants and People

Botanical Dimensions has been doing good work with plants and people for almost thirty years! Founded in 1985 by Kathleen Harrison and Terence McKenna, this non-profit organization is dedicated to ethnobotanical knowledge in its myriad forms.

PLEASE SUPPORT US DURING THE YEAR’S END CHALLENGE GRANT ~ Donate by 12/31/2015. Tax-deductible donations will help us match a $4800 donation! And become a member!


Our original mission was “to collect, protect, propagate and understand plants of ethno-medical significance and their lore.” We do all that and more. We work to preserve biodiversity, respecting natural ecosystems and traditions of ecological knowledge. We appreciate, study, and educate others about plants and mushrooms that are felt to be significant to cultural integrity and spiritual well-being. We share what we learn.

Projects – Our new Ethnobotany Library is open!

Our purpose and passion are rooted in the folk-knowledge and uses—both traditional and contemporary—of the flora and fungi of our little planet. Ethnobotany—the relationship between plants and people—is the primary lens we look through in choosing our projects. Ethnobotany is a vast, branching area of study, filled with marvels, challenges and solutions.

The themes of our projects illustrate some of the branches of ethnobotany and ethnomycology. In late 2015, we are thrilled to announce the opening of our Ethnobotany Library. Please lend your support to this unique, non-profit offering. See the blog post about it for details. We also engage in these kinds of activities:

  • Fieldwork in various cultures, particularly among indigenous peoples of the Americas
  • Document folk uses of plants and fungi, with photography, audio and video recordings, participatory observation, and ethnographic writing
  • Assist cultural revitalization projects involving plants, fungi and knowledge of nature
  • Support local experts in preserving botanical species and herbarium collections
  • Make the ethnobotanical perspective and its cultural techniques available to a wider appreciation, through teaching and sharing information and images
  • Sponsor field courses that foster global ethnobotanical awareness, with specific, hands-on, cultural experiences
  • Educate and empower students to recognize, observe and document plant uses
  • Protect or restore native species in disrupted natural habitats
  • Consider the ecological history of a given place, and how that affects the perception and stewardship of nature by humans
