1 BEN LOCKWOOD DAVID C. LEBLANC DEPT. OF BIOLOGY, BALL STATE UNIVERSITY Growth-Climate Associations for White Ash (Fraxinus americana L.) in Monroe County, Indiana

2 Introduction Justification  Limited information regarding white ash  Limited time to acquire it  Climate is changing Objective  Identify growth-climate association for white ash in well drained soil  Compare white ash & white oak growth- climate associations

3 Study Site Hoosier National Forest

4 Methods Sampling  D/C-D  > 50 yrs.  Undamaged  15 trees  2 cores per tree Measuring  Earlywood (EW)  Latewood (LW)  Total (RW)

5 Methods Mean chronology  1932 – 2012  Cross-dating & standardization  Standard dendrochronological methods Climate Data  NOAA & Historical Climate Network  Monthly climate variables  Seasonal climate variables Pearson’s correlation coefficient

6 Mean Monthly Maximum Temperature

7 Total Monthly Precipitation

8 Palmer Drought Severity Index

9 White Ash & White Oak Comparison (Total RW)

10 Results White ash EW  Prior to growing season White ash LW  Water stress during current growing season (June) White ash & white oak (total RW)  Similar growth-climate associations Summary

11 Discussion Minimal influence of climate on EW during growing season Most climate sensitivity found in LW during growing season Carbon allocation model Foster and LeBlanc (1993)
