Required Input Tables

All OSM variants require two input tables that describe, respectively:

· Stand-level or plot-level inventory attributes

· Tree-level inventory attributes

Information in these two tables are linked by one column ‘SurveyID’.

OSM Stand List Table (OSM_StandList)

This documentation only describes additional columns defined by the Acadian Variant. See OSM documentation on input tables for all columns required or recognized.

Additional table columns defined by the Acadian variant

Column	Type	Constraint	Default	Description
Acadian Models
Zone	Text	NB, ME, PE, NS	NB	Political jurisdiction. NB = New Brunswick; ME = Maine; PE = PEI; NS = Nova Scotia
Management	Text	None, Clearcut, Plant, PCT, PartialCut	None	Management Code: · None (no recent management history; > 25 years) · PartialCut (partial harvest < 25 years ago; extensive management) · Clearcut (<25 years old, no regeneration management) · PCT (was pre-commercially thinned) · Plant (planted and intensively managed through rotation).
BGI	Float	>=0 or Null	3500	Biomass Growth Index (kg/ha/year) used to determine site productivity for default growth and height models. www.forusresearch.com\bgi.php
PoorSite	Boolean	-	FALSE	If PoorSite = TRUE, then growth, ingrowth, survival, and stocking may be reduced.
ClimateIndex	Float	b/w 1 & 40	13.5	Climate index used for some depreciated Acadian growth models that can still be turned on in the Variant for testing purposes. Unless you are testing different growth or height models in this version of the software, you do not need this column under default calibration. The ingrowth model still depends on Climate Index, but this variable as little effect on this model and the default value of 13.5 is the average for the Acadian forest region.
STAMAN Models (these models have been depreciated but can still be switched on for testing purposes; not required for default models)
NbClimate	Byte| Text	[1] Mountain [2] Uplands [3] Lowlands	2	STAMAN Climate Zone Used for most STAMAN tree models.
NbSite	Byte| Text	[1] Best [2] Good [3] Moderate [4] Poor	3	STAMAN Site Class Used for most STAMAN tree models.

OSM Tree List Table (OSM_TreeList)

See OSM documentation on input tables. No additional tree attributes defined by the Acadian Variant.
