Tebughna Ethnobotany: Plants as Living Relatives

Traditional Ecological Knowledge of Western Cook Inlet Flora

Ethnobotany is the study of how human cultures interact with and utilize native plants for food, medicine, shelter, tools, and spiritual ceremonies.

For thousands of years, Tebughna people thrived in the Tyonek region because of an intimate understanding of the life cycles and medicinal potencies of every forest plant.

  • 🌿
    Living Pharmacy: Native plants provided remedies for colds, infections, cuts, and joint pain.
  • 🥗
    Nutritional Bounty: Wild greens and roots provided vital vitamins and starches alongside fish and game.

Essential Inquiries & Learning Targets

Core Essential Questions:

  • How have the Tebughna Dena’ina utilized sub-arctic flora for food, medicine, tools, and spiritual wellness for centuries?
  • What core traditional harvesting ethics guide respectful plant gathering on ancestral lands?
  • How do modern botanical and pharmaceutical sciences validate traditional medicinal uses of plants like wormwood, spruce pitch, and Labrador tea?

Student Learning Objectives:

  • Identify 8 key traditional plants utilized by the Tebughna Dena’ina and their seasonal harvesting calendars.
  • Practice honorable harvesting ethics: never take the first or last plant, take only what is needed, and leave root systems intact.
  • Connect traditional preparations (teas, salves, smudges, baskets) to active botanical compounds.

Cultural

🏔️ Local Alaskan & Tebughna Context

  • Tebughna territory encompasses diverse ecosystems: coastal mudflats, muskeg bogs, boreal forests, and sub-alpine tundra.
  • Elders pass down oral plant knowledge: wild wormwood (ts'elveni) for colds and aches, spruce pitch for cuts and sealants, and fireweed for tea and spring greens.
  • Always emphasize respect and reciprocity with the natural world.

📦 Required Materials & Classroom Setup

✓ Field plant press or heavy phone books lined with cardboard✓ Clean cotton gathering bags or woven baskets✓ Magnifying loupe✓ Plant identification cards with Dena’ina and English names

🔬 Step-by-Step Hands-on Activity Guide

  1. Step 1: Review Harvesting Ethics with Elders

    Before touching any plants, discuss the 3 sacred rules: 1) Ask permission and show gratitude, 2) Never take the first or last plant, 3) Take no more than 1/3 of the patch.

    💡 Instructor Tip: Always harvest leaves gently without yanking underground root crowns.

  2. Step 2: Botanical Identification in Field

    Locate specimen plants (Fireweed, Labrador Tea, Wormwood). Examine leaf veins, fragrance, flower structure, and habitat.

    💡 Instructor Tip: Crush a tiny leaf corner to smell characteristic herbal aromas.

  3. Step 3: Preserve Botanical Specimens

    Place gathered samples between blotter paper in the plant press. Tighten straps to flatten and dehydrate specimens for a permanent herbarium reference.

    💡 Instructor Tip: Change blotter paper every 2 days to prevent sub-arctic mold.

💬 Wrap-Up Discussion & Evidence of Learning

Discussion Questions:

  • Why is Traditional Ecological Knowledge (TEK) considered an empirical science built on centuries of observation?
  • How does passing traditional plant knowledge to Tebughna youth strengthen cultural identity and food sovereignty?

Evidence of Learning Rubric:

  • Student recites the three rules of honorable harvesting.
  • Student correctly identifies 5 local plants by their ecological niche and cultural use.
