Geospatial forest inventory dataset updated for depletions, such as harvesting, and projected annually for growth. Sample attributes in this dataset include: age, species, volume, height. The Vegetation Resources Inventory (VRI) spatial datasets describe both where a vegetation resource (ie timber volume, tree species) is located and how much of a given resource is within an inventory unit.

####Leading Group for the Cariboo Region (pinegroup or firgroup). #### 1. IDF - Fir Group: includes all forest polygons in NDT 4 (IDF and BG biogeoclimatic zones) that meet any of the following criteria: *a) Douglas-fir ( Fd or Fdi) leading or ponderosa pine leading; *b) Lodgepole pine leading, and Douglas-fir ( Fd or Fdi) or ponderosa pine greater than 15% in any inventory layer; *c) Trembling aspen leading, and Douglas-fir ( Fd or Fdi) or Ponderosa pine greater than 15% in any inventory layer, and spruce, red-cedar, cottonwood and birch less than 6% in any inventory layer; *d) No species information in inventory data (usually NSR stands), and inventory type group for pre-harvest stand or the current stand = 1, 2, 3, 4, 5, 6, 7, 8, 29, or 32 These inventory type groups correspond to the following species compositions F, FC, FCy, FH, FS, FPl, Fpy, FL, FDEcid, PlF and Py. If inventory type group=0 and pre-harvest inventory type is not available, classify the polygon as Pine Group. 2. IDF-Pl Group: includes all forest polygons in NDT 4 (IDF and BG biogeoclimatic zones) that do not meet the above definition for IDF-Fir Group.

The spatial representation for an Inventory Region or Compartment. Established by the Resource Inventory Branch, Inventory Regions are large drainages encompassing groups of small drainages also known as compartments. These were once used for planning purposes, similar to the current Planning Cells. They are now maintained in the files as reference for many administration boundaries

The spatial representation for a Public Sustained Yield Unit, which is an area of Crown land, usually a natural topographic unit determined by drainage areas, managed for sustained yield by the Crown through the Ministry of Forests. It includes all Crown lands within the currently established boundaries of the unit and excludes federal lands, provincial parks, experimental forest reserves, gazetted watersheds and tree farm licences. Crown land designated as a public sustained yield unit under Section 6 of the Forest Act. A portion of a TSA

__The link: *Access the data directory* is available in the section*Dataset Description Sheets; Additional Information*__.The layer of **ecological planning units (UPE) ** constitutes the territorial base at the base of the ecoforest inventory process in southern Quebec (IEQM). It was created and then integrated as part of the current inventory (fifth IEQM). It integrates concepts that are both administrative (forest region) and ecological (ecological region). More precisely, the division is done on an ecological basis within each of the forest regions. It is on this basis that the activities of the IEQM are planned.Each of the layers included in the IEQM monitoring datasets reports on what has been achieved as part of the current inventory. We are talking here about aerial photography, mapping, terrestrial sampling of temporary sample plots, and compilation activities. Each year, new territories are added to each layer to reflect the progress of the work.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

Sensitive Ecosystems Inventory (SEI) Project Boundaries (STE_SEI_PROJECT_BOUNDARIES_SVW) contain boundaries (study areas) and attributes describing each SEI project (project level metadata), and includes links to the locations of other data associated with the project (e.g. reports, polygon datasets, plot files). This layer is derived from the [STE_TEI_PROJECT_BOUNDARIES_SP](https://catalogue.data.gov.bc.ca/dataset/1313fac7-2ea1-4c6b-995b-bd421b7ec3c6) layer by filtering on the PROJECT_TYPE attribute. Project types include: SEI, TEMSEI, TEMSET, SEIWHR and NEMSEI. SEI project boundaries should be used in conjunction with SEI detailed inventory polygons which identify and map rare and fragile terrestrial ecosystems in a given area for the purpose of encouraging land-use decisions that will ensure the continued integrity of these ecosystems. SEI inventory polygons with full Resources Information Standards Committee (RISC) attributes can be accessed through the [Terrestrial Ecosystem Information (TEI) Data Distribution Packages](https://catalogue.data.gov.bc.ca/dataset/8fd15e4e-e7b1-4566-81d1-1ff8947bfd46). SEI inventory polygons with simplified and amalgamated (concatenated) RISC attributes can be accessed through the [Sensitive Ecosystems Inventory (SEI) Detailed Polygons with Short Attribute Table Spatial View](https://catalogue.data.gov.bc.ca/dataset/b00fd09f-ebe1-4b52-9717-6ef9c243d52e). **Current version**: v12 (2026-06-22)

Predicted bulk density (g/cm3) at defined depth ranges (0–5 cm, 5–15 cm, 15–30 cm, 30–60 cm, 60–100 cm). The mass of dry soil per unit bulk volume.

An administrative unit of forest land designated by the Minister, as authorized under Section 14(1) of the Forests Act.

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.
