 "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",
