The B.C. Conservation Data Centre’s spatial view of publicly available, known locations of species and ecological communities at risk. This spatial view is split into the "Publicly Available Occurrences" layer and "(Extirpated and Historical) Publicly Available Occurrences" layer. The Extirpated and Historical layer includes element occurrences that have a last observation date greater than 40 years ago and element occurrences that are extirpated due to general habitat loss or degradation of the environment in the area. Use the field ‘Rank Description’ to differentiate between Historical and Extirpated element occurrences in this layer.

All element occurrences are polygons: the size of the polygon usually reflects the locational uncertainty associated with the source data, represented with varying sized circles. Some polygons may be larger to reflect the actual area covered by the element occurrence. The field "Representational Accuracy" is used to communicate how accurately the polygon reflects the actual area covered by the element.

If you do not find an element occurrence in your area of interest, this means there are none currently mapped in the CDC database. The best way to verify whether an area contains a species or ecosystem at risk is to have do a detailed assessment of the property during the appropriate season.

Additional Information

Purpose

Prevent accidental destruction of a location of a species or ecological community at risk and for research and analysis.
Lineage Statement

The Conservation Data Centre follows NatureServe Element Occurrence Data Standards (2003). Records mapped prior to 2003 were mapped to an older standard.

Object Description

Object Name: WHSE_TERRESTRIAL_ECOLOGY.BIOT_OCCR_NON_SENS_AREA_SVW

Short Name: BIO_NS_SVW
Comments: This view exposes the BIOTIC occurrence area with the attributes for a non sensitive BIOTIC occurrence. An Occurrence is a specific geographic location that represents a habitat capable of sustaining or contributing to the survival of specified species. This view does not includes Endangered Species, nor Record Trees.

Column Name Short Name Data Type Data Precision Comments
OCCR_AREA_SP_ID OCCR_R__ID NUMBER 10 Primary unique numeric identifier for a Polygon.
FEATURE_CODE FEATURE_CD VARCHAR2 10 A standard numeric 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.
SHAPE_ID SHAPE_ID NUMBER 10 Shape ID is the unique identifier for each polygon. Used to label occurrences on map products.
