A list of the site series ecological units of the current biogeoclimatic ecosystem classification. Site series are subdivisions of the biogeoclimatic subzone/variant, and describe sites capable of producing the same mature or climax vegetation unit (plant association or sometimes, subassociation). Site series are described in the Regional Field Guides to Site Identification. Site and soil conditions, and the vegetation community, are used to identify site series

Object Description

Object Name: WHSE_FOREST_VEGETATION.BEC_SITE_SERIES_CATALOGUE

Short Name: BEC_SER_CT

Column Name Short Name Data Type Data Precision Comments
SITE_SERIES_CATALOGUE_ID STSRSCTLGD NUMBER 5 Assigned numeric identifier for a site series unique within a biogeoclimatic unit.
REGION_CODE RGNCD VARCHAR2 9 A code uniquely identifying a BEC Region.
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.
SITE_SERIES STSRS VARCHAR2 12 A number from 01 to 99 representing the soil moisture regime and soil nutrient regime of a site series, relative to other site series within a subzone or variant.
SITE_SERIES_PHASE STSRSPHS VARCHAR2 9 A subdivision of a site series used when site or soil properties differ sufficiently to affect management prescriptions.
SITE_SERIES_VARIATION STSRSVRTN NUMBER 1 Site variation describes divergent vegetative trends or floristic features and is usually related to short-term successional factors and recent stand history.
SERAL SERAL VARCHAR2 12 Seral code; may be seral association (4 lower case alphabetic) or seral developmental or structural stage (2 upper case alphabetic)
REGION_NAME RGNNM VARCHAR2 360 A full description of the BEC Region Code.
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.
SITE_SERIES_DESCRIPTION STSRSDSCRP VARCHAR2 240 A connotative label, made up of the names of the potentially dominant plant species for a site series.
