Ecosection boundaries with percent protected, number of overlapping protected areas and other attributes added as a result of geoprocessing in the Protected Area System Overview (PASO) application. Protected area and park representation by ecosection provides a landscape context for natural resource planning processes such as; management plans, land use zoning, environmental risk assessment, landscape analysis, habitat supply, and management of high priority species. Ecosections are distinguished from each other by enduring characteristics such as minor physiographic and macroclimatic or oceanographic variations. For more information on ecosections and the Ecoregion Classification System see: http://www.env.gov.bc.ca/ecology/ecoregions/index.html. For important warnings about using this data for spatial analysis see the Data Quality section of the metadata

Additional Information


Protected area representation analysis assists resource managers to assess the relative importance of maintaining the ecosystem at a specific site based on how much similar ecosystem in other locations is already protected from substantial alteration by humans.

Object Description


Comments: PASO PCT ECOSECT PRTCTD SVW represents areas with minor physiographic and macroclimatic or oceanographic variations. The spatial geometry is combined with provincial totals that provides a high level summary of ecosection representation found within and outside the protected areas system. Ecosections are used for resource emphasis and area planning. This is a multipart feature class.

Column Name Short Name Data Type Data Precision Comments
ECOSECTION_CODE CSCTNCD VARCHAR2 3 ECOSECTION CODE is three letter Ecosection primary unique code (e.g. TEB, PEP) .
FEATURE_CODE FTRCD VARCHAR2 10 FEATURE CODE is a standard alphanumeric code to identify the type of feature represented by the spatial data. A feature code is most importantly a means of linking a feature to its name and definition. For example, the code GB15300120 on a digital geographic feature links it to the name "Lake - Dry" with the definition "A lake bed from which all water has drained or evaporated." The feature code does NOT mark when it was digitized, what dataset it belongs to, how accurate it is, what it should look like when plotted, or who is responsible for updating it. It only says what it represents in the real world. It also doesn't even matter how the lake is represented. If it is a very small lake, it may be stored as a point feature. If it is large enough to have a shape at the scale of data capture, it may be stored as an outline, or a closed polygon. The same feature code still links it to the same definition.
ECOSECTION_NAME CSCTNNM VARCHAR2 50 ECOSECTION NAME is theEcosection full name (e.g. "Whitehorse Upland", "Tatshenshini Basin").
PARENT_ECOREGION_CODE PRNTCRGNCD VARCHAR2 3 PARENT ECOREGION CODE is the code for the Ecoregion that completely contains this Ecosection. Foreign key to ERC_ECOREGIONS_SP.
EFFECTIVE_DATE FFCTVDT DATE 7 EFFECTIVE DATE is the date the feature was first included in the dataset.
EXPIRY_DATE XPRDT DATE 7 EXPIRY DATE is the date the feature was removed from the dataset, or replaced with a new feature.
ESECT_NM ESECT_NM VARCHAR2 40 ESECT NM is the ecosection number. The Ecoregion Classification System divides the province into 10 large units called 'ecoprovinces', each having distinct climate and landforms. Ecoprovinces are divided into 48 smaller units called 'ecoregions' and further divided into'ecosections' by more detailed differences in climate and landforms. There are 133 ecosections in the province.
ESAREAPR ESAREAPR NUMBER 38 ESAREAPR describes how many hectares of a particular Ecosection there is in the entire provincial land base.
PRPA_ES PRPA_ES NUMBER 38 PRPA ES describes how many hectares of a particular Ecosection are protected in the province.
NUMPA_ES NUMPA_ES NUMBER 38 NUMPA ES describes how many protected areas exist in this Ecosection. This number will be the same for all protected areas within this Ecosection.
PCTESPR PCTESPR NUMBER 38 PCTESPR describes what percent of a particular Ecosection is protected in the province by all protected areas combined.
PCTPPAES PCTPPAES NUMBER 38 PCTPPAES describes what percent of the entire protected areas system is made up of a particular Ecosection, i.e. this gives you provincial representation of the Ecosection for all protected areas.
FEATURE_AREA_SQM AREA_SQM NUMBER 19 FEATURE_AREA_SQM is the system calculated area of a two-dimensional polygon in square meters.
FEATURE_LENGTH_M FEAT_LEN NUMBER 19 EATURE_LENGTH_M is the system calculated length or perimeter of a geometry in meters.
GEOMETRY GEOMETRY SDO_GEOMETRY 64 GEOMETRY is an ArcSDE spatial column: coordinates defining the features.
OBJECTID OBJECTID NUMBER 38 OBJECTID is a required attribute of feature classes and object classes in a GeoDatabase.
SE_ANNO_CAD_DATA BLOB 4000 SE_ANNO_CAD_DATA is a binary column used by spatial tools to store annotation, curve features and CAD data when using the SDO_GEOMETRY storage data type.
