The B.C. Conservation Data Centre spatial layer that displays a generalised area that masks the precise locations of secured occurrences of species and ecosystems at risk. These are masked for public viewing and download. The occurrences may be secured due to the species or ecosystems being susceptible to persecution or harm, or for proprietary reasons. For information or to obtain details about Masked Occurrence Records, please contact the CDC at cdcdata@gov.bc.ca and provide projects details including precise location information and activities expected to occur on site or other reasons for requiring the information. Release of details of secured occurrences is subject to the signing of a Confidentiality and Non-reproduction Agreement and a demonstrated "need-to-know".

Data and Resources

Dataset Extent

Latitude: 48.0° to 60.0°
Longitude: -139.5° to -113.5°

Additional Information


Alert users to approximate secured locations of species and ecosystems at risk. Users concerned about disturbing one of these locations should contact the CDC for more information.

Lineage Statement

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

Object Description


Short Name: BIOT_MS_SP
Comments: Non Sensitive occurrence area is a specific geographic location that represents a habitat capable of sustaining or contributing to the survival of specified species that are not defined as "Endangered Species".

Column Name Short Name Data Type Data Precision Comments
OCCR_MASKED_SENS_AREA_SP_ID OMS_ASP_ID NUMBER 10 OCCR MASKED SENS AREA ID is primary unique numeric identifier for the multipolygon.
ADVISORY ADVISORY VARCHAR2 255 ADVISORY is a comment that provides advice, caveats, etc. on the use or interpretation of this record, e.g., Warning: There are one or more secured occurrences in this/these area(s): Please contact cdcdata@gov.bc.ca and provide your project details.
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 LENGTH_M NUMBER 19 FEATURE_LENGTH_M is the system calculated length or perimeter of a geometry in meters.
GEOMETRY GEOMETRY SDO_GEOMETRY 1 GEOMETRY is the column used to reference the spatial coordinates defining the feature.
OBJECTID OBJECTID NUMBER 38 OBJECTID is a column required by spatial layers that interact with ESRI ArcSDE. It is populated with unique values automatically by SDE.
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.
