Table Fields - ECOLOGICAL REGIONS

Domain ID Number associated with domain (X000)
Domain A subcontinental area of broadly similar climate. The three Canadian domains are distinguished by air-mass frequency, mean July temperature, degree days (accumulated number of degrees each day's temperature is above 5.6° C) in the growing season (number of days with an average temperature over 5.6° C), mean annual precipitation, season of maximum precipitation, and mean annual evaporation from small lakes.
Division ID Number associated with division (XX00)
Division

A subdivision of a domain, defined by regional climate, soil order, extent of permafrost, and dominant vegetation

Province ID Number associated with province (XXX0)
Province A subdivision of a division, defined by soil groups, flora, and fauna. The mammals and birds listed are mainly those important for human subsistence. Fish are described by importance to native users (most important staple, staple, unimportant), by productivity in kg/km 2 (kilograms per square kilometre), and by occurrence in fresh water or in the sea (marine).
Section ID Number associated with section (XXXX)
Section Description A subdivision of a province, defined by landforms, relief, elevation range and average, glacial and water deposits, percentage of fresh water and wetlands, and flora
