  1. Conservation Efforts and Economic Feasibility of Preserving Clematis socialis Courtney Holt May 1, 2005

  2. Species Background • Alabama leather flower • Distribution • Reproduction

  3. Status • Endangered • Threats • Management efforts • Species recovery plan (USFWS) • Increasing population sizes • Boyd and Hilton (1994)

  4. Conservation Efforts

  5. Tissue Culturing • Collection of plant tissue • Grown on media • Hormones • Nutrients • Sugars • Undefined constituents • Acclimation

  6. Shoot Growth • 103 shoot and flower bud samples collected on March 16, 2000 • Growth media • 0.5 mg/l BAP, 0.5 mg/l NAA • Antibiotics • Removal of NAA and increase in BAP to 1.0 mg/l increased shoot production

  7. Root Growth • Cultures with successful shoots transferred to medium with 0.5mg/l IBA • Some transferred to hormone-free media • 50% rooting • Some left on 0.5IBA media • 62% rooting

  8. Acclimation • 80 mm terra cotta pots • 1:1 sand soil mixture • Covered with clear plastic cups • Plants remained small ex vitro • Potential reintroduction

  9. Further Efforts at Root Growth • Decrease in rooting success with .5IBA WP • Plants taken from all 17 lines and placed on either • .5IBA WP (38 plants) • .5IBA 1/2WP (37 plants) • Shoot height recorded

  10. Root Density

  11. Shoot Growth

  12. Economic Feasibility

  13. Methods of Valuation • Use values • Passive-use values • Option value • Existence value • Combinations of these values typically motivate preservation

  14. Contingent Valuation • Directly places value on resource, species, etc. • People are asked their willingness to pay contingent on a hypothetical scenario

  15. Surveys • 4 survey types • Black and white picture • Color picture • In-state • Only in Alabama • Open-ended question

  16. Survey Results

  17. Total Payment Projections • Willingness to pay extrapolated using US population (18 years and older) • $6,485 spent by CREW per year on C. socialis

  18. Conclusions • Conservation efforts appear to have support for C. socialis • Support for larger variety of species? • More extensive surveys necessary

  19. Questions?
