NARRATIVE
	
IN THIS CLASSIFICATION ALL MINERAL AND ORGANIC SOILS ARE GROUPED
INTO ONE OF SEVEN CLASSES BASED UPON THEIR INHERENT ABILITY TO GROW 
COMMERCIAL TIMBER.  THE BEST LANDS OF CANADA FOR COMMERCIAL TREE GROWTH 
WILL BE FOUND IN CLASS 1 AND THOSE IN CLASS 7 CANNOT BE EXPECTED TO 
YIELD TIMBER IN COMMERCIAL QUANTITIES;  THESE REPRESENT THE EXTREMES, 
BECAUSE OF UNSUITABLE CLIMATE NO CLASS 1 LANDS WILL BE FOUND IN SEVERAL 
REGIONS OF CANADA SNF IN CERTAIN REGIONS THE CLASS 2 AREAS WILL BE TOO 
SMALL TO SHOW AT THE CHOSEN SCALES OF MAPPING.

SOME OF THE IMPORTANT FACTORS ON WHICH THE CLASSIFICATION IS BASED ARE:

	ALL KNOWN OR INFERRED INFORMATION ABOUT THE AREA INCLUDING 
	SUBSOIL, SOIL PROFILE, DEPTH MOISTURE, FERTILITY, LANDFORM, 
	CLIMATE AND VEGETATION.

	ASSOCIATED WITH EACH CAPABILITY CLASS IS A PRODUCTIVITY RANGE 
	BASED ON THE MEAN ANNUAL INCREMENT OF THE BEST SPECIES OF GROUP 
	OF SPECIES ADAPTED TO THE SITE AT OR NEAR ROTATION AGE
	PRODUCTIVITY CLASSES ARE EXPRESSED IN GROSS MERCHANTABLE CUBIC 
	FOOT VOLUME TO A MINIMUM DIAMETER OF FOUR INCHES.  THINNINGS, 
	BARK AND BRANCH WOOD ARE NOT INCLUDED.  THE PRODUCTIVITY AS 
	EXPRESSED IS THAT OF "NORMAL", I.E. FULLY-STOCKED STANDS.  IT 
	MAY BE ASSUMED THAT ONLY GOOD MANAGEMENT WOULD HAVE PRODUCED 
	STANDS OF THIS NATURE.

	THE FOLLOWING ARE NOT CONSIDERED:  LOCATION, ACCESS, DISTANCE TO 
	MARKETS, SIZE OF UNITS, OWNERSHIP, PRESENT STATE OR SPECIAL CROPS 
	SUCH AS CHRISTMAS TREES.

THE CLASSES ARE BASED ON THE NATURAL STATE OF THE LAND WITHOUT
IMPROVEMENTS SUCH AS FERTILIZATION, DRAINAGE OR AMELIORATION PRACTICES, 
IT IS REALIZED THAT WITH IMPROVED FOREST MANAGEMENT THE PRODUCTIVITY MAY 
CHANGE;  TO THE EXTENT THAT THE LIMITATIONS SHOWN IN THE SUBSOIL MAY BE 
ALTERED, CLASS CHANGES MAY ALSO TAKE PLACE.  HOWEVER, SIGNIFICANT 
CHANGES WILL ONLY BE ACHIEVED THROUGH COSTLY AND CONTINUING PRACTICES.

CLASS DESCRIPTIONS

	CLASS 1 LANDS HAVING NO IMPORTANT LIMITATIONS TO THE GROWTH OF 
		COMMERCIAL FORESTS.  
		SOILS ARE DEEP, PERMEABLE, OF MEDIUM TEXTURE, MODERATELY 
		WELL-DRAINED TO IMPERFECTLY DRAINED, HAVE GOOD WATER-
		HOLDING CAPACITY AND ARE NATURALLY HIGH IN FERTILITY.  
		THEIR TOPOGRAPHIC POSITION IS SUCH THAT THEY FREQUENTLY 
		RECEIVE SEEPAGE AND NUTRIENTS FROM ADJACENT AREAS.  THEY 
		ARE NOT SUBJECT TO EXTREMES OF TEMPERATURE OR EVAPO-
		TRANSPIRATION.  PRODUCTIVITY WILL USUALLY BE GREATER THAN 
		111 CUBIC FEET PER ACRE PER YEAR. 
 		WHEN REQUIRE THIS CLASS MAY BE SUBDIVIDED ON THE BASIS 
		OF PRODUCTIVITY INTO CLASSES: '1 ', (111 CUBIC FEET TO
		130 CUBIC FEET); '1A', (131 CUBIC FEET TO 150 CUBIC
		FEET); '1B', (151 CUBIC FEET TO 170 CUBIC FEET); '1C',
		(171 CUBIC FEET TO 190 CUBIC FEET); '1D', (191 CUBIC FEET
		TO 210 CUBIC FEET); AND BY 20 CUBIC FOOT CLASSES 
		THEREAFTER, AS NECESSARY, BY CODING THE APPROPRIATE 
		ALPHABETIC CHARACTER IN THE MODIFIER POSITION.

	CLASS 2 LANDS HAVING SLIGHT LIMITATIONS TO THE GROWTH OF 
		COMMERCIAL FOREST.  
		SOILS ARE DEEP, WELL-DRAINED, TO MODERATELY WELL-DRAINED,
		OF MEDIUM TO FINE TEXTURE AND HAVE GOOD WATER-HOLDING 
		CAPACITY.  THE MOST COMMON LIMITATIONS (ALL OF A 
		RELATIVELY SLIGHT NATURE) ARE:  ADVERSE CLIMATE, SOIL 
		MOISTURE DEFICIENCY, RESTRICTED ROOTING DEPTH, SOMEWHAT 
		LOW FERTILITY, AND THE CUMULATIVE EFFECTS OF SEVERAL 
		MINOR ADVERSE SOIL CHARACTERISTICS.  PRODUCTIVITY WILL 
		USUALLY BE FROM 91 TO 110 CUBIC FEET/ACRE/YEAR.

	CLASS 3 LANDS HAVING MODERATE LIMITATIONS TO THE GROWTH OF 
		COMMERCIAL FORESTS.  
		SOILS MAY BE DEEP TO SOMEWHAT SHALLOW, WELL TO 
		IMPERFECTLY DRAINED, OF MEDIUM TO FINE TEXTURE WITH 
		MODERATE TO GOOD WATER-HOLDING CAPACITY.  THEY MAY BE 
		SLIGHTLY LOW IN FERTILITY OR SUFFER FROM PERIODIC 
		MOISTURE IMBALANCES.  THE MOST COMMON LIMITATIONS ARE:  
		ADVERSE CLIMATE, RESTRICTED ROOTING DEPTH, MODERATE 
		DEFICIENCY OR EXCESS OF SOIL MOISTURE, SOMEWHAT LOW 
		FERTILITY, IMPEDE SOIL DRAINAGE, EXPOSURE (IN MARITIME 
		AREAS) AND OCCASIONAL INUNDATION.  PRODUCTIVITY WILL 
		USUALLY BE FROM 71 TO 90 CUBIC FEET/ACRE/YEAR.

	CLASS 4	LANDS HAVING MODERATELY SEVERE LIMITATIONS TO THE GROWTH 
		OF COMMERCIAL FOREST.  
		SOILS MAY VARY FROM DEEP TO MODERATELY SHALLOW, FROM 
		EXCESSIVE THROUGH IMPERFECT TO POOR DRAINAGE, FROM COARSE 
		THROUGH FINE TEXTURE, FROM GOOD TO POOR MOISTURE HOLDING 
		CAPACITY, FROM GOOD TO POOR STRUCTURE AND FROM GOOD TO 
		LOW NATURAL FERTILITY.  THE MOST COMMON LIMITATIONS ARE:  
		MOISTURE DEFICIENCY OR EXCESS, ADVERSE CLIMATE, 
		RESTRICTED ROOTING DEPTH, POOR STRUCTURE, EXCESSIVE 
		CARBONATES, EXPOSURE, OR LOW FERTILITY.  PRODUCTIVITY 
		WILL USUALLY BE FROM 51 TO 70 CUBIC FEET/ACRE/
		YEAR.

	CLASS 5	LANDS HAVING SEVERE LIMITATIONS TO THE GROWTH OF 
		COMMERCIAL FORESTS.  
		SOILS ARE FREQUENTLY SHALLOW TO BEDROCK, STONEY, 
		EXCESSIVELY OR POORLY DRAINED, OF COARSE OR FINE TEXTURE, 
		MAY HAVE POOR MOISTURE HOLDING CAPACITY AND MAY BE LOW IN 
		NATURAL FERTILITY.  THE MOST COMMON LIMITATIONS (OFTEN IN 
		COMBINATION: ARE:  MOISTURE DEFICIENCY OR EXCESS, 
		SHALLOWNESS TO BEDROCK, ADVERSE REGIONAL OR LOCAL 
		CLIMATE, LOW NATURAL FERTILITY, EXPOSURE PARTICULARLY IN 
		MARITIME AREAS, EXCESSIVE STONINESS AND HIGH LEVELS OF 
		CARBONATES.  PRODUCTIVITY WILL USUALLY BE FROM 31 TO 50 
		CUBIC FEET PER ACRE PER YEAR.

	CLASS 6	LANDS HAVING SEVERE LIMITATIONS TO THE GROWTH OF 
		COMMERCIAL FORESTS.   
		THE MINERAL SOILS ARE FREQUENTLY SHALLOW, STONEY, 
		EXCESSIVELY DRAINED, OF COARSE TEXTURE AND LOW IN 
		FERTILITY.  A LARGE PERCENTAGE OF THE LAND IN THIS CLASS 
		IS COMPOSED OF POORLY DRAINED ORGANIC SOILS.  THE MOST 
		COMMON LIMITATIONS (FREQUENTLY IN COMBINATION) ARE:  
		SHALLOWNESS TO BEDROCK, DEFICIENCY OR EXCESS OF SOIL 
		MOISTURE, HIGH LEVELS OF SOLUBLE SALTS, LOW NATURAL 
		FERTILITY, EXPOSURE, INUNDATION AND STONINESS.  
		PRODUCTIVITY WILL USUALLY BE FROM 11 TO 30 CUBIC FEET/
		ACRE PER YEAR.

	CLASS 7	LANDS HAVING SEVERE LIMITATIONS WHICH PRECLUDE THE GROWTH 
		OF COMMERCIAL FORESTS.  
		MINERAL SOILS ARE USUALLY EXTREMELY SHALLOW TO BEDROCK, 
		SUBJECT TO REGULAR FLOODING, OR CONTAIN TOXIC LEVELS OF 
		SOLUBLE SALTS.  ACTIVELY ERODING OR EXTREMELY DRY SOILS 
		MAY ALSO BE PLACED IN THIS CLASS. A LARGE PERCENTAGE OF 
		THE LAND IS VERY POORLY DRAINED ORGANIC SOILS.  THE MOST 
		COMMON LIMITATIONS ARE:  SHALLOWNESS TO BEDROCK, EXCESSIVE 
		SOIL MOISTURE, FREQUENT INUNDATION, ACTIVE EROSION, TOXIC 
		LEVELS OF SOLUBLE SALTS, AND EXTREMES OF CLIMATE OR
		EXPOSURE. PRODUCTIVITY WILL USUALLY BE LESS THAN 10 
		CUBIC FEET PER ACRE PER YEAR.
