Maps are of unknown provinancecommentsany notes for the tree, year of notation not always included

Each measured tree has a metal tag with a unique tag number (trees have been re-tagged multiple times, latest re-tag in 2018; 2018 tags are currently in use)year_addedthe first year a tree was tagged and measured
10
Tag numbers prior to 2012 are included in the 'Tags & Plots' worksheet, but have not been quality controlledyear_of_mortalitythe year that a tree was discovered dead
11
Each measured tree has a stripe of orange marking paint at dbh levelcurrent_statusthe current mortality status of an individual tree
