Attributes in entity 3: Individual tree mortality

     Details
1. DBCODE
Definition: FSDB Database code
Domain: enum
2. ENTITY
Definition: Entity number
Units: number
Domain: range (minimum = 3.  maximum = 3.)
3. TREEID
Definition: Tree identification code represented as STANDID+PLOTID+00000, where 00000 represents a unique tree number for that stand and plot
Domain: freetext
4. PSP_STUDYID
Definition: Permanent Study Plots (PSP) study identification code - a mutually exclusive grouping of study forest stands
Domain: place
5. STANDID
Definition: Study forest stand or watershed identification code
Domain: place
6. PLOTNUMBER
Definition: Plot number within STANDID
Units: number
Domain: range (minimum = 0.  maximum = 1005.)
7. SPECIES
Definition: Tree species code (Taxonomic reference: Garrison and Skovlin 1976)
Domain: taxa
8. TAG
Definition: Current tree tag number
Units: number
Domain: range (minimum = 0.  maximum = 9999.)
9. YEAR
Definition: Year of establishment, remeasurement, or mortality
Units: number
Domain: range (minimum = 1915.  maximum = 2018.)
10. DBH_LAST
Definition: Last measured tree diameter at breast height (1.37m) - typically from last remeasurement as dbh is usually not measured for dead trees
Units: centimeters
Domain: range (minimum = 0.3  maximum = 252.3)
11. MAIN_STEM
Definition: Main stem condition code (use of this code begins in 2010)
Domain: enum
12. ROOTING
Definition: Tree rooting condition code (use of this code begins in 2010)
Domain: enum
13. POSITION
Definition: Tree position (used prior to 2010); describes the physical position of the tree; POSITION is replaced with two separate measurements of MAIN_STEM and ROOTING beginning 2010
Domain: enum
14. CROWN_PCT
Definition: Percent of a tree's live crown volume that is still intact along the stem (does not apply to uprooted trees); record for living trees begins in 2010 (Entity 2) - only recorded when mortality is noted before 2010 (Entity 3).
Units: percent
Domain: range (minimum = 0.  maximum = 100.)
15. TREE_PCT
Definition: Percent of the entire main stem length that is intact (does not apply to uprooted trees); record for living trees begins in 2010 (Entity 2) - only recorded when mortality is noted before 2010 (Entity 3).
Units: percent
Domain: range (minimum = 0.  maximum = 100.)
16. LEAN_ANGLE
Definition: Angle of tree lean in degrees from vertical, where vertical is 0 degrees (not recorded for uprooted trees); record for living trees begins in 2010 (Entity 2) - only recorded when mortality is noted before 2010 (Entity 3).
Units: degrees angle
Domain: range (minimum = 0.  maximum = 170.)
17. GROUND_PCT
Definition: Percent of the down portion of the tree bole that is in direct contact with the ground (does not include branch contact). Only applies to MAIN_STEM code= 1,2 or POSITION code=2,4
Units: percent
Domain: range (minimum = 0.  maximum = 100.)
18. SUPPORT_PCT
Definition: Percent of the down portion of the tree bole that is suppored above the ground (by its own branches, other trees or downed logs, or other objects such as rocks). Only applies to MAIN_STEM code= 1,2 or POSITION code=2,4
Units: percent
Domain: range (minimum = 0.  maximum = 100.)
19. MORT_CAUSE1
Definition: Proximate mortality cause: the immediate cause that precipitates tree death (defined as primary mortality cause before 2010)
Domain: enum
20. MORT_CAUSE2
Definition: Predisposing mortality cause: any condition that produces a susceptibility or disposition to tree death without actually causing it (defined as secondary or contributing mortality cause before 2010)
Domain: enum
21. CONDITION1

Domain: enum
22. CONDITION2
Definition: Condition code 2 - general tree health indicator is one of potentially six noted conditions in arbitrary order
Domain: enum
23. CONDITION3
Definition: Condition code 3 - general tree health indicator is one of potentially six noted conditions in arbitrary order
Domain: enum
24. CONDITION4
Definition: Condition code 4 - general tree health indicator is one of potentially six noted conditions in arbitrary order
Domain: enum
25. CONDITION5
