## TREE DATA

- National Manual Version 1.55

## Subplot Number

- Coded separately from tree number

## Tree Record Number

- Three digit code
- SK2:  Georgia use same old tree numbers, start with next available for new trees
- SK 1, 3:  Start at 001
- SK 9: Arkansas start at 001

## Condition Class Number

- Put the trees in the condition they belong to:

## Azimuth &Horizontal Distance

- No change

## Present Tree Status

- Formerly called “Tree History”
- The following
- New codes are one digit:
- 0	No Status
- Live Tree
- Dead
- 3	Removal
- 4	Missing

- SK2 remeasured trees
- Code **“0”** for _**No Status**_ – Tree is not presently in the sample (remeasured plots only).  The tree was incorrectly tallied at the previous survey or currently is not tallied due to definition or procedural change.
- Code **“4”** for _**Missing**_ – A tree was tallied in previous inventory but now is missing due to natural causes such as landslide, fire, etc. (remeasured plots only).

## New Tree Reconcile

- For remeasured locations only
- Record a NEW TREE RECONCILE for any new tally tree that was not tallied in the previous inventory; this code is used to identify the reason a new tree appeared in the inventory.

**Codes:**
_**Ingrowth**_ – New tally tree not qualifying as through growth (includes reversions and, on sample kind = 2 plots, the new off-set micorplot tally).
_**THROUGH Growth**_ – New tally tree 5.0 inches DBH and larger within the microplot (including co-located microplot).
_**Missed Live Tree**_ – A live tree missed at previous inventory and that is live, dead or removed now
_**Missed Dead**_ – A dead tree missed at previous inventory and that is dead or removed now.

## Lean Angle

- Record the code that describes the angle of lean from vertical of the tree from the base to top of actual length.
- Trees supported by other trees or by their own branches are considered standing.
**	****0**	_**Standing**_ (less than 45 degrees of lean)
**	****1  **  _**Down**_ (more than 45 degrees of lean)

## Species

- There are several Species codes that have changed!!
- Use code 299 for unknown dead conifers and 999 for unknown dead hardwoods when the generic or species codes cannot be used.
- The generic code (e.g. 400, 540) should only be used when you are sure the species is on the species list, but you cannot differentiate among acceptable species.

## Current Diameter at Breast Height (DBH)

- The following has changed:

## Slide 13

## Questions about DBH

- What do you do when you measure a diameter above 4.5’ and it is a 10.9” Hardwood?  Do you give this tree a Tree Grade?
- What do you do when the tree is 4.9” above an abnormality @ 4.5’

## DBH for Remeasured Trees

- Remeasuring the diameter of a tree tallied at a previous survey, take the measurement at the location monumented by the previous crew unless it is not physically possible
- Except the previous location is more than **12 inches** beyond where the diameter should be measured according to current protocols
- Assign a DIAMETER CHECK code of 2 whenever the point of remeasurement is moved.

## Length To Diameter Measurement Point

- For those trees measured directly at 4.5 ft above the ground, leave this item blank.
- If the diameter is measured above 4.5 ft, record the actual length from the ground, to the nearest 0.1 in

## Percent Rotten/Missing Cull

- Formerly called “Cubic Foot Cull”
- No changes except instead of 5% increments we are now coding Rotten/Missing Cull to the nearest 1%

## Percent Board Foot Cull

- No changes except instead of 5% increments, we are now coding Rotten/Missing Cull to the nearest 1%
- Make changes on page App 3-16

## Total Length &Actual Length

- TOTAL LENGTH is to the nearest 1.0 ft from ground level to the tip of the apical meristem.  If the tree has a broken or missing top, estimate what the total length would be if there were no missing or broken top.
- ACTUAL LENGTH – for trees with broken or missing tops, record the length of the remaining portion of the tree.

## Length Method

- Record the code that indicates the method used to determine tree lengths.
- 1 Total and actual lengths are field 		     measured with a measurement 	    		     instrument (e.g., clinometer, relascope, tape)
- 2 Total length is visually estimated, actual length is measured with an instrument.
- 3 Total and actual lengths are visually  		     estimated.

## Compacted Crown Ratio

- No real change except that the coding is the actual percent
- No range codes

## Fusiform/Comandra Rust/Hardwood Dieback

- Record the incidence of fusiform, comandra rust and dieback.
**0****         **_**None**_
**1****         **_**Fusiform**_, _**Comandra Rust**_:  		  Only on slash and loblolly
**2****        **_** **__**Dieback**_:  HARDWOODS ONLY

## Dieback Severity

- Record the severity of hardwood dieback
- 1 = 10 to 19%
- 2 = 20 to 29%
- Etc....

## Cause of Death

- Record the cause of death for all trees that have died, been cut or moved into a landcleared or remeasured condition since the previous survey.  If cause of death cannot be reliably estimated, record unknown/not sure.

- 10	 Insect
- 20	 Disease
- 30	 Fire
- 40	 Animal
- 50	 Weather
- 60	 Vegetation (suppression, competition, vines/kudzu)
- 70	 Unknown/not sure/other

- 80	 Human (other than below)
-    81	 Logging (cut or killed, utilized or not        	 utilized)
-    82	 Timber Stand Improvement
-    83	 Landclearing (cut or killed, utilized  	 or not utilized)
- Physical (hit by falling tree)

## 5200 Mortality Year

- Record the estimated year that remeasured trees died or were cut
- Examples:  1998, 1999, 2000, etc.

## Slide 27

## 5220 Utilization Class

- Record the code to identify cut trees that have been removed from the site.
**00 **_**Not utilized**_
**11 **_**Commercial utilization**_ – some portion of the tree removed for commercial purposes.
**12  **_**Non-commercial utilization**_ – some portion of the tree removed for non-commercial purposes.

## Tree Notes

- Record notes pertaining to an individual tree as called for to explain or describe another variable
