This layer is now the authoritative source for locating Active Growth and Yield plots also known as Permanent Sample Plots (PSPs). Any possible conflict with PSPs or harvest developments in the area of an active PSP need to be discussed with a FAIB Inventory Forester. Please contact Anya Reid (Anya.Reid@gov.bc.ca) with the Sample ID numbers for the plots in question. NOTE: Accuracy of the coordinates are variable. More recently (since 2000) measured plots generally have post processed GPS coordinates, which are quite accurate (3m). However, plots measured in the 1990's have a wide range of coordinate accuracy. In all cases, it is necessary to ground truth plot location before block layout. This layer replaces the [Growth and Yield Samples – Active Status](https://catalogue.data.gov.bc.ca/dataset/0ca49478-5d0f-44e8-b6af-3fd6e387803c) layer with more accurate and current information from the Inventory Sample Management Consolidation (ISMC) database.

TOPEX (acronym which means “topographical exposure”) is an index of topographic exposure. It reflects the influence of local topography on the degree of exposure to wind and on its behavior (Ruel et al. 2002). TOPEX data are presented in the form of a matrix file (raster) whose spatial resolution is 50 m with a projection in Nad 1983 Quebec Lambert. This raster covers the entire territory of Quebec located approximately south of 52°40' and west of 61°10' and extends beyond the borders of Quebec by 75 to 125 m (in order to have values on the entire Quebec territory covered). TOPEX values were calculated using the Digital Terrain Model (DTM) from the NASA Shuttle Radar Topography Mission (SRTM). This MNT is provided in a WGS 84 projection (EPSG: 4326) with a resolution of one arcsecond (+/- 30 m). A mosaic of the SRTM tiles was created to then project the MNT into Lambert and resample it at 50 m. TOPEX can be used as an input in a windfall vulnerability assessment system. However, it should be borne in mind that this index does not take into account the wind channeling effect that may occur in some places and that can influence windfall. In addition, other factors must be taken into consideration in order to carry out a complete analysis of the risk of windfall. RUEL, J.-C., S. J. MITCHELL and M. DORNIER, 2002.

Web map of Manitoba's forest inventory in 2021. This web map is used within Manitoba's Five Year Report on the Status of Forestry, 2016 - 2021 story map. Web map of Manitoba's forest inventory in 2021. This web map is used within Manitoba's Five Year Report on the Status of Forestry, 2016 - 2021 story map. The web map includes all of the Forest Resource Inventory (FRI) and Forest Land Inventory (FLI) interpreted data that forms Manitoba's 'green zone'.  For Manitoba's northern portion where FRI/FLI data does not exist (white zone), North American Land Change Monitoring System (NALCMS) data from 2015 was updated and used.

This dataset represents Manitoba's digital forest inventory for the 1960s. Please note that because of data capture techniques used for this inventory, its base features (e.g., water, roads) may not align with other datasets (e.g., Google Maps, Esri Basemaps) This dataset represents Manitoba's digital forest inventory for the 1960s. It was created from forest inventories captured by photo-interpretation during different time periods in the 1960s. It consists of original inventory polygons without any subsequent modifications, such as disturbance or silvicultural activities. Please note that, because of data capture techniques used for this inventory, its base features (e.g., water, roads) may not align with other datasets (e.g., Google Maps, Esri Basemaps).This dataset covers a large portion of the middle of Manitoba, and is almost exclusively within the Boreal Plains and Boreal Shield ecozones. Forest inventories created in the 1960s used the Forest Resource Inventory (FRI) standards to capture details about the land base relevant to forestry, along with non-forest base features. Data collected in the FRI standard included, among other things, tree species composition, site class (site growing conditions), cutting class (stand maturity, and a proxy for age), crown closure and productivity. This dataset also includes estimated age and year of photography attributes.This feature class is also available for download from DataMB .Metadata: Manitoba Forest Inventory –1960s

Metadata: Manitoba Forest Inventory —1970s | This dataset represents Manitoba's digital forest inventory for the 1970s. It was created from forest inventories captured by photo-interpretation at various periods in the 1970s. These are the original inventory polygons, without any subsequent changes, such as disturbances or silvicultural activities. Please note that due to the data entry techniques used for this inventory, the basic characteristics (e.g., water, roads) may not match other data sets (e.g., Google Maps, Esri Basemaps) .This dataset covers a large portion of central Manitoba and is located almost exclusively in the Boreal Plains and Boreal Shield ecozones. Forest inventories created in the 1970s used Forest Resources Inventory (IRF) standards to capture land base details relevant to forestry, as well as characteristics of the non-forest land base. Data collected under the IRF standard included, among other things, tree species composition, site class (site growth conditions), stand operational class (stand maturity and age approximation), canopy closure, and productivity, among others. This data set also includes attributes such as the estimated age and year of the photo.This feature class can also be downloaded from MB Data.Metadata: Manitoba Forest Inventory — 1970s **This third party metadata element was translated using an automated translation tool (Amazon Translate).**
