Description: The 1:50 000 Land Capability for Forestry in Nova Scotia data was digitized from hardcopy maps produced for the Canada Land Inventory program. It classifies all mineral and organic soils in Nova Scotia into one of seven classes based on their inherent ability to grow commercial timber. 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 symbol may be altered, class changes may also take place. However, significant changes will only be achieved through costly and continuing practices.Field Definitions:ACLASS, BCLASS, CCLASSNo important limitations to the growth of commercial forests - 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 capability 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 temperatures or evapotranspiration. Productivity will usually be greater than 111 cubic feet per acre per year. When requires, this clss may be subdivied on the basis of productivity into class 1 (111 to 130), 1a (131 to 150), 1b (151 to 170), 1c (171 to 190), 1d (191 to 210) and by 20 cubic foot classes thereafter, as necessary. Does not have subclasses. Slight limitations to the growth of commercial forests - Lands having slight limitations to the growth of commercial forests. 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 relatively slight nature) are adverse climate, soil moisture defiency, restricted rooting depth, somewhat low fertility and the cumulative effects of several minor adverse soil characteristics. Productivity will usually be from 90 to 110 cubic feet per acre per yearModerate limitations to the growth of commercial forests - 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, impeded soil drainage, exposure (in maritime areas) and occasional innundation. Productivity will usually be from 71 to 90 cubic feet per acre per yearModerately severe limitations to the growth of commercial forests - Lands having moderately severe limitations to the growth of commercial forests. 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 pr acre per year.Severe limitations to the growth of commercial forest (Productivity 31 to 50 ft2/yr) - Lands having severe limitations to the growth of commercial forest. Soils are frequently shallow to bedrock, stoney, excessively or poorly drained of coarse or fine texture, may have poor moisture holding capacity and 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 year.Severe limitations to the growth of commercial forest (Productivity 11 to 30 ft2/yr) - Lands having severe limitations to the growth of commercial forest. The mineral soils are frequently shallow, stoney, excessively drained, of coarse texture and low in fertility. A large percentage of the land in the 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 per acre per year.Severe limitations which preclude the growth of commercial forest - Lands having severe limitations which preclude the growth of commercial forest. 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.

Description: Land Systems mapped at 1:50,000 from the Nova Scotia Biophysical Land Classification were used to define the physical attributes of the smallest mapped unit of the ELC - the Ecosection (1:50,000). Infrared aerial photography (1:63,560) flown in 1976 and used to determine the Land Systems was also used to re-check Ecosection boundaries. In addition the following were used to assist in the delineation of Ecosections, Ecodistricts and Ecoregions: Provincial soils maps - 1:50,000; 1:63,000; 1:126,000 Surficial geology maps - 1:500,000; 1:100,000 National topographic series - 1:50,000 Forestry mapping - 1:10,000 Geology - 1:640,000 Radarsat 3D imagery The Climate for Agriculture in Canada (1985) The Natural History of Nova Scotia (1996) Geological Background and Physiography of Nova Scotia (1982) A National Ecological Framework for Canada (1995) Ecoregions and Ecodistricts of Nova Scotia (1999) Natural Landscapes of Nova Scotia (1997)To download the digital data, please visit: http://www.gov.ns.ca/natr/forestry/gis/licence.asp?url=../gis/elcdata.aspField Definition:NDR;Open seral - Ecosystems where site conditions restrict or limit tree growth. Some of these site limitations are a result of repeated disturbances such as fire. Other limitations are a result of natural processes such as extreme exposure to wind and seasonal flooding. Also in this class are wetlands where excessive moisture, thick peat layers and heavy ericaceous vegetation restrict tree growth.Frequent - Disturbances which result in the rapid mortality of an existing stand and the establishment of a new stand of relatively even age. The interval between stand initiating events is normally shorter than the average longevity of the dominant species.Gap - Stands of this disturbance regime are seldom exposed to stand initiating disturbances. They are characterized by gap and small patch mortality, followed by understory recruitment, resulting in stands with multiple age classes.Infrequent - Stand initiating events are characteristics in the development of these stands, but the interval between events is normally understory recruitment to evolve and become evident.UnclassifiedTOPOGRAPHY;Smooth - is land showing no particular pattern with a smooth topography.Hummocky - is a series of small rounded hills having their height less than 1.5 times their base with a relief amplitude up to 15 mHills - include knobs (small rounded hills having their height greater than 1.5 times their base with a relief amplitude up to 45 m) and knolls (hills having their height less than 1.5 times their base with a relief amplitude from 15 to 60 m.)Drumlins and flutes - are caused by glacial ice movement and are recognized in patterns of elongated smooth streamlined hills (drumlins) and shallow straight parallel troughs (flutes).Dissections - are narrow canyons flowing from hilly or mountainous topography or steep slopeRidged - is a pattern of linear or curvilinear ridges associated with the underlying geomorphology (bedrock).Water - Additional topography codes added for areas that were not part of the ecosection codingSalty marsh - Additional topography codes added for areas that were not part of the ecosection codingUrban - Additional topography codes added for areas that were not part of the ecosection codingCoastal beach - Additional topography codes added for areas that were not part of the ecosection coding
