Abstract:

15 spontaneous stands of pedunculate oak were sampled in the Landes region close to Bordeaux. In each stand, all the oaks were cored with an increment borer. The 661 cores were measured to get series of annual growth. The ring-width data were cross dated and standardized with RCS method. The dataset is composed of two files: (1) description of 661 trees, (2) growth data of 21461 tree rings.

Text:

8 variables in columns and 661 lines for cored pedunculate oaks 1. Patch : a letter is the name of each of the 15 forest stands 2. Tree : tree name. Example : K_001_A means K = stand, 001 = tree number in this stand, A = name of the cored stem when a tree was multi-stemmed 3. TreeAge : tree age from seed; this age was inferred from dendrochronology information 4. FirstYear : year of the oldest tree-ring on the core (pith) 5. LastYear : year of the last tree-ring on the core (under bark) 6. DBHStem : diameter at breast height of the cored stem (cm) 7. DBHTree : diameter at breast height of the tree calculated from measurement of the circumference with a forest tape (in cm). DBHTree = DBHStem when the tree had only one stem, if not DBHTree > DBHStem 8. Corrector = BATree/BaStem. This ratio allows to correct the growth for multi-stemmed trees. We cored only stem per tree but the wood was produced in all the stems. Therefore, corrected BAI = BAI * corrector. Corrected BA and BAI are labelled BAc and BAIc in the file TreeRingData.txt. In the case of trees with only one stem, corrector = 1, then BA = BAc and BAI = BAIc

14 variables in columns and 21 461 tree rings of Quercus robur 1. Patch : a letter is the name of each of the 15 forest stands 2. Tree : tree name. Example : K_001_A means K = stand, 001 = tree number in this stand, A = name of the cored stem when a tree was multi-stemmed 3. Year : tree-ring year 4. RW : ring width (mm) 5. DC : Distance between the pith and the first tree-ring on the core (mm); DC = 0 when the cored reached the pith 6. SupTR : Supplementary Tree Ring = number of missed tree-rings when the core did not reach the pith. SupTR = 0 when the core crossed the pith (bravo) 7. RingAge : tree-ring cambial age, i.e. tree-ring number from the pith, taking into annount SupTR. The series begins at 1 when the core reached the pith 8. CumRay : Cumulated radius of the tree from the pith to the current year (cm); it takes into account DC 9. BA : Basal Area (cm2) ; stem area under bark at the current year at the height of coring 10. BAI : Basal Area Increment (cm2) ; wood area of the tree-ring 11. Corrector = BATree/BaStem. This ratio allows to correct the growth for multi-stemmed trees. We cored only one stem per tree but the wood was produced in all the stems 12. BAc = BA * corrector (cm2) 13. BAIc = BAI * corrector (cm2). This the best estimator of the annual growth of the tree. 14. GI : Growth Index (%). This is the standardized BAIc taking into account the effect of cambial age (Regional Curve Standardization method)
