A list of the various 'regional' (zone/subzone/variant/phase) ecological units of the current biogeoclimatic ecosystem classification. At this 'regional' level, vegetation, soils and topography are used to infer the climate and to identify geographic areas that have relatively uniform climate. These geographic areas are termed biogeoclimatic units. The basic biogeoclimatic unit is the Subzone. These units are grouped into Zones and may be further subdivided into variants based on further refinements of climate (e.g., wetter, drier, snowier). The map units of the Biogeoclimatic map are mapped to the highest possible thematic resolution - subzone or variant. In some cases, where further sampling is required to define the unit climatically, polygons are labelled as an undifferentiated unit (e.g. CWH un)

Additional Information

Purpose

This attribute catalogue contains a description of the unique biogeoclimatic zones/subzones/variants/phases in the current provincial biogeoclimatic map. The Biogeoclimatic map is used for a wide variety of applications in British Columbia. A few examples include: Delineation of Natural Disturbance Types for Landscape Unit Planning. Delineation of Select Seed - Seed Planning Zones. As an input for Predictive Ecosystem Mapping. Reporting on the ecological representation of the Protected Areas Strategy. As a level in the classification hierarchy for Broad Ecosystem Units.

Lineage Statement

The Biogeoclimatic attribute catalogue (a.k.a BECdb) is loaded into Oracle where it is validated before it is replicated to the LRDW.

Object Description

Object Name: WHSE_FOREST_VEGETATION.BEC_BIOGEOCLIMATIC_CATALOGUE

Short Name: BEC_CATALG

Column Name Short Name Data Type Data Precision Comments
BIOGEOCLIMATIC_CATALOGUE_ID BGCLMTCCTL NUMBER 10 Assigned numeric identifier for a biogeoclimatic catalog entry unique within a biogeoclimatic unit.
ZONE ZONE VARCHAR2 12 A code uniquely identifying a Biogeoclimatic Zone of interest to MOF.
SUBZONE SUBZONE VARCHAR2 9 A code uniquely identifying a Biogeoclimatic SubZone of interest to MOF. A code used to designate a division of a specific biogeoclimatic Zone; a geographic area with a fairly uniform regional climate and a typical pattern of vegetation and soils. Subzones are not unique. They are only meaningful in conjunction with a Zone.
VARIANT VARIANT VARCHAR2 3 A one digit number used to denote a division of a specific biogeoclimatic subzone; A geographic area with a more specific regional climate. A variant has a specific pattern of vegetation and soils. Variants are only meaningful within a Zon
PHASE PHASE VARCHAR2 3 A one character code used to denote an atypical area, resulting from local relief, in the regional climate of the subzones and variants. Phases are not unique. They only have meaning in combination with a specific Zone, Subzone and Variant.
NATURAL_DISTURBANCE NTRLDSTRBN VARCHAR2 12 The Natural Disturbance of interest to MOF. A code used to designate a period process or event such as insect outbreaks, fire, disease, flooding, windstorms and avalanches that cause ecosystem change and renewal. The Code values range from 1-5 inclusive.
ZONE_NAME ZONE_NAME VARCHAR2 105 A descriptive name given to a large geographic area having similar patterns of energy flow, vegetation, and soils as a result of a broad, homogeneous macroclimate. Zone names describe the major vegetation contained within the zone.
SUBZONE_NAME SBZNNM VARCHAR2 105 A descriptive name given to a division of the biogeoclimatic zone. Subzone names define the normal regional climate for the division of a biogeoclimatic zone.
VARIANT_NAME VRNTNM VARCHAR2 60 A descriptive name given to a division of the biogeoclimatic subzone. Variant names usualy denote a location within the biogeoclimatic subzone e.g. Eastern or Okanagan areas within a subzone.
PHASE_NAME PHASE_NAME VARCHAR2 45 A descriptive name given to an atypical area, resulting from local relief, in the regional climate of the subzones and variants. Phases may denote a different type of vegetation(e.g grassland within a Douglas Fir subzone), a difference in c
NATURAL_DISTURBANCE_NAME NTRLDSTRB1 VARCHAR2 360 A full description of the Natural Disturbance.
NOTES NOTES VARCHAR2 216 A comment on the Zone, Subzone, Variant, Phase.
