  1. By: John Ortiz Tae-Han Yeo CV Creek Restoration

  2. Purpose • Increase biodiversity of campus • To give information to future campus restoration groups involved in blackberry removal so projects progress from a good starting point

  3. What are Invasive Species? • Invasive species • Non-native plant, animal, microorganisms that take over the habitat of native species • Introduced either accidentally or intentionally • Invasive always considered pests or harmful to ecosystem • Tend to be • Highly competitive • Highly adaptive • High successful at breeding • Lack of natural predators causes them to thrive • Result in biodiversity loss (HIPPO) • ‘I’ stands for invasive species

  4. Recommendations • Use weed whacker • Cut 6-12 inches above ground and remove stalks • Next day, remove root crowns with shovels • Drier days are easier to remove root crowns

  5. Steps on Removing Blackberries • Cut back the surrounding vines to access base of the stalks using weed whacker, leaving 6-8 inches of the base. • Use spades to shovel around base of the revealed stalk. • Reveal roots by using the shovel as a lever and lifting. • Pull root crowns out of the dirt using gardening gloves, careful not to shake small parts of the roots back into the soil. • Put the roots crowns into garbage bags to be put in municipal yard waste. • We disposed of stalks in the compost pile. • Observe disposed stalks for possible growth.

  6. Problems • Oregon Weather • Communication • Need to plant local replacement plants, achieves: • Increase biodiversity • Decrease soil erosion • Time consuming to remove large area • Funding

  7. Natural Step – Step 1 1. Take • Can the earth replace what I consume? Are the materials renewable? • This would be met if we replaced with native plants • Part of future plans • Soil still retains its fertility

  8. Natural Step – Step 2 2.Make • Am I poisoning the earth, water or air? • Didn’t use herbicide or other poisons • No synthetics or toxics • Used all natural removal methods

  9. Natural Step – Step 3 3. Respect • Do I honor the biodiversity of life? • Removed invasive species • Future plans involve replacing with local plants

  10. Natural Step – Step 4 4. Choose • Are the decisions I make fair and equitable (human rights)? • We worked ourselves and with class volunteers • We only beat Luke when absolutely necessary

  11. 2nd Semester Goals Achieved • Revised interactive CV campus map • Surveyed land and identified/targeted invasive • Cleared a 100 sq. foot patch of blackberries • Identified natural ground cover plants

  12. Native Replacement Plants • Fool’s huckleberry • Salmonberry • Red huckleberry

  13. Clearing Blackberries

  14. Conclusion • Blackberries time-consuming to remove • Leaving stalks in school compost does not grow more blackberries • Root crowns must be disposed elsewhere • domestic yard waste • Important to replace with native plants

  15. Future Plans • Share information with future classes • Meet with administrators • Determine what ground cover plants to use • Work more on the field • Create organization or club that maintains campus • Target other invasives
