The Forest Inventory Zone(s) (FIZ) were developed to provide a broadly based ecological classification of the forest land in British Columbia. FIZ closely follow the early biogeoclimatic zones developed by Dr. Krajina. The province of British Columbia is split into 12 FIZ zones.

Data and Resources

Dataset Extent

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

Additional Information

Purpose

Used to indicate the area of the polygon located within a FIZ. Used in conjunction with Public Sustained Yield Until to assign stand volume. However, this is no longer used within forest inventory volumes. These days FIZ is only used for Timber Evaluation of Timber Operations and Pricing.

Lineage Statement

FIZ code is assigned using a table lookup based on Inventory_Region, Compartment. FIZ code was used as index to coefficients for calculating all volumes, diameters, MAI's and basal areas. This has been replaced based on BEC (biogeoclimatic).

Object Description

Object Name: WHSE_ADMIN_BOUNDARIES.FADM_FOREST_INVENTORY_ZONES_SP

Short Name: FADM_FIZ
Comments: The Forest Inventory Zones (FIZ) were developed to provide a broadly based ecological classification of the forest land in BC. The province is split into 12 FIZ zones with FIZ boundaries closely following the early Biogeoclimatic Zones developed by Dr. Krajina. A FIZ code is assigned using a lookup table based on Forest Inventory Region and Compartment. Previously, FIZ codes were used as an index to coefficients for calculating all volumes, diameters, Mean Annual Increments (MAI) and Basal Areas.

Column Name Short Name Data Type Data Precision Comments
FOREST_INVENTORY_ZONE_ID FRST_NV_ID NUMBER 10 FOREST INVENTORY ZONE ID is a system generated unique identification number.
FOREST_INVENTORY_ZONE FIZ_NAME VARCHAR2 1 FOREST INVENTORY ZONE is one of twelve forest inventory zones which represent a broadly based ecological classification of the forest land in the province, e.g., A, B, C.
FEATURE_AREA_SQM FEAT_AREA 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 FEATURE LENGTH M is the system calculated length or perimeter of a geometry in meters.
SHAPE SHAPE SDO_GEOMETRY 1 SHAPE 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 ANNO_CAD 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.
