1. \Data\American_chestnut_VT_core_data_EWW.csv: CSV file containing tree identification, core identification, and earlywood widths for 208 increment cores (107 sampled trees).

Variables include:

TreeID = Unique identifier for each of the 107 individual trees sampled. From left to right, the identifier corresponds to replicate (1 or 2), subplot (1, 2, 3, 4, 5, or 6), and individual tree number (01, 02, 03, 04, 05, 06, 07, 08, 09, 10, 11, 12, 13, 14, 15, or 16).

CoreID = Unique identifier for each of the 208 individual cores collected. From left to right, the identifier corresponds to replicate (1 or 2), subplot (1, 2, 3, 4, 5, or 6), individual tree number (01, 02, 03, 04, 05, 06, 07, 08, 09, 10, 11, 12, 13, 14, 15, or 16), individual core letter (A, B or C).

[YEAR] = Earlywood widths, in millimeters, for each [YEAR] beginning with the most recent ring 2018 (Column C) to the oldest possible ring 2010 (Column K).



2. \Data\American_chestnut_VT_core_data_LWW.csv: CSV file containing tree identification, core identification, and latewood widths for 208 increment cores (107 sampled trees).
