1. Developing Edition 3.0 of CIPSANON
David W. Hann
February 24, 2016

2. Differences Between Editions
Edition 1.0 – Used ORGANON software and annual equations from both SWO and SMC Type I
Edition 2.0 – Used software that had been modified/improved specifically for CIPS and annual equations from both SWO and SMC Type I
Edition 3.0 – Uses Edition 2.0 software and SWO equations, but the SMC equations have been replaced by the PNW annual equations developed by Doug Mainwaring

3. All Editions of CIPSANON are composed of two DLLs: CIPSEDIT and CIPSRUN
Each DLL contains equations and parameters for two versions of CIPSANON: SWO and either SMC or PNW.

4. The SWO version incorporates equations and parameters for 18 species with the option of using either site index or WHC20 and PPTDD41.
The SMC or PNW version incorporates equations and parameters for 11 species using just site index.

5. CIPSEDIT.DLL utilizes 7 static and 3 dynamic species-specific equations.

6. Static equations in CIPSEDIT.DLL include predictors of:
Maximum crown width of open grown trees - NWO
DIB from DBH – SWO
DBH from DIB - SWO
Height-diameter for all living trees - SMC
Height-to-crown-base for all living trees
Dominant height
Diameter at 11.8” above ground

7. Dynamic equations in CIPSEDIT.DLL include predictors of:
Diameter increment of trees on untreated plots
Probability of mortality of trees on untreated plots
Change in weed cover

8. CIPSRUN.DLL utilizes 10 static and 17 dynamic species-specific equations.

9. Static equations in CIPSRUN.DLL include predictors of:
Maximum crown width of open grown trees - NWO
Largest crown width of stand growth trees - NWO
Height to the largest crown width - NWO
Crown width at any point in the crown - NWO
Height-diameter for undamaged trees - SMC
Height-to-crown-base for undamaged trees
Maximum height-to-crown-base from CCFL - SMC
Maximum height/DBH ratio from DBH - SMC
Maximum size-density trajectory - SMC
Bruce (1981) Dominant height
Diameter at 11.8” above the ground
DBH assignment when height exceeds 4.5-feet

10. Height Increment Diameter Increment Mortality Rate
Dynamic equations in CIPSRUN.DLL include predictors of:
Height Increment
Diameter Increment
Mortality Rate
Change in Weed Cover

11. Height Increment Equations
Bruce (1981) dominant height increment
Height increment of trees on untreated plots
Average of the largest 1/3 of the height increment residuals
Average of the smallest 1/3 of the height increment residuals
Thinning impact upon height increment - SMC
Fertilization impact upon height increment - SMC
Genetic improvement impact upon height increment
Swiss needle cast infection impact upon height increment
Weed cover impact upon height increment
Can be applied to trees below breast height

12. Diameter Increment Equations
Diameter increment of trees on untreated plots
Average of the largest 1/3 of the diameter increment residuals
Average of the smallest 1/3 of the diameter increment residuals
Thinning impact upon diameter increment - SMC
Fertilization impact upon diameter increment - SMC
Genetic improvement impact upon diameter increment
Swiss needle cast infection impact upon diameter increment
Weed cover impact upon diameter increment

13. Mortality Rate Equations
Probability of mortality on untreated plots
Fertilization impact upon probability of mortality
Can be applied to trees below breast height

14. Comparison of Predictions
The following are a comparison of predictions from:
SMC-ORGANON Edition 9.1
SMC-CIPSANON Edition 2.0
PNW-CIPSANON Edition 3.0

15. Comparison of Predictions
Tree lists from three SMC Type I installations were used to make the projections
Installation
Plot
Age from Seed
Bruce’s Site Index
733 4 20
77.3
732 11 18
126.6
711 5 9
172.8

16. Comparison of Predictions
Each plot was projected up to 80 years from seed and the following plot-level attributes were graphed for each plot:
Total stem cubic foot volume per acre (TSCFV)
Basal area per acre (BA)
Number of trees per acre (TPA)
Top height (H40)
Stand density index (SDI)
