  1. Longleaf Pine Study Chipola College Marianna, Florida Dr. David Hilton Dr. Santine Cuccio Kari Kind-Adams Carole Chandler Lori Holland Debbie Yglesias

  2. Information Regarding Longleaf Pines Latin name: Pinuspalustris • Can live 500 years • Have a deep taproot (2-3 meters) • Require sandy soil • Found in Southeastern US • Uses: turpentine, timber, resin • 97% of native longleaf pine forests have disappeared • Home to red-cockaded woodpecker

  3. Stage 1: Grass Stage • 5-12 years • Resistant to fire • May take years to reach ankle height

  4. Stage 2: Rocket Stage • Can grow 1.5 meters in one season • Early part of this stage pines are vulnerable to fire • Later in stage (2.5 meters) they are resistant

  5. Stage 3: Adult Stage • 150 years until maturity is reached • Can grow to 30-35 meters tall • Can measure 0.7 meters in diameter • Highly resistant to fire

  6. Our Question Is there a correlation between longleaf pine height and diameter? Can tree height be accurately predicted by measuring stem diameter? Hypothesis There is a strong correlation between longleaf pine height and diameter, at least for a period of time.

  7. Materials

  8. Procedures Random sample of 20% Only living trees were counted Failure rate: 58%

  9. Procedures: Height Measured height to the top of the needles

  10. Procedures: Diameter Measured diameter 5 centimeters from the base of plant

  11. Procedures

  12. Data

  13. Scatter Plot Height (m) Diameter (cm)

  14. Bar Graph Number of Trees Height (m)

  15. GPS Map

  16. Conclusions There appears to be a strong positive correlation between longleaf pine diameter and height at four years old. How long this trend continues will be assessed again in 2 years as part of the longitudinal study.
