Forest Tenure Harvesting Authority Polygons
This is a spatial layer that reflects operational activities for harvesting authorities. The harvesting authority is a legal area cleared by the Ministry of Forests and Range (that is, no other claims for the land exist) for harvesting purposes. This corresponds to the outlined areas on the Exhibit A maps. The Forest Tenures Section (FTS) is responsible for the creation and maintenance of digital Forest Atlas files for the province of British Columbia encompassing Forest and Range Act Tenures. It also supports the forest resources programs delivered by the MoFR. Each feature contains a Ministry of Forests and Range (MoFR) FEATURE_CLASS_SKEY (number) column that further defines the type of that feature. The layer contains harvesting authority boundaries for the following feature classes: Christmas Tree Permit (489), Forest Licence Cutting Permit (556), Licence to Cut (615), Timber Licence Cutting Permit (811), Timber Sale Licence Major Cutting Permit (818), Timber Sale Licence Minor (819), Tree Farm Licence Cutting Permit (834), WoodLot Licence Cutting Permit (864), Timber Sale Licence Minor Cutting Permit (917), and Community Forest Cutting Permit (2401). Each harvesting authority has a life cycle status code that is either PENDING - the harvesting authority has been submitted as a new harvesting authority or an amendment, but is not yet approved or rejected, ACTIVE - the harvesting authority is approved and activities may be taking place on the harvesting authority, or RETIRED - all activities have been completed for the harvesting authority

Timber harvest plans - 50k
The purpose of this feature class is to identify those areas that are in the process of Timber Harvest Planning, process being a continuum from proposed plan through to approval and eventually plan expiration. Subsection 20(3) of the Forest Resources Act establishes that an approved Timber Harvest Plan is required prior to the authorization of timber harvesting under a Harvesting Licence or authorization of a Forest Resources Permit for non-commercial timber harvesting in an amount greater than 25m3 per year. A Timber Harvest Plan:• Must be developed in accordance with Sections 5 through 7 of the Forest Resources Regulation. • Identifies forest resources in the area and areas suitable for timber harvesting and establishes objectives for timber harvesting.• Must be consistent with any Forest Resources Management Plan that applies to the same area.Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .

FADM - Designated Areas
Defines areas protected from harvesting activities by Order-in-Council as per part 13 of the Forest Act.
Forest Resources Management Plans - 250k
The purpose of this feature class is to identify the individual annual allowable cut and annual limit areas as referred to in the Forest Resources Act subsection 20(2) and 31(10 of the Forest Resources Regulation). Where there is no approved Forest Resources Management Plan (FRMP) for an area, forest resources harvesting can only be authorized in an amount less than that prescribed by regulation for that area. The Forest Resources Regulation subsection 31(1) establishes the annual limits for harvesting timber resources for areas without an FRMP. These areas are referred to as the Annual Limit Regions in Schedule 1 of the Regulation titled Timber Harvesting Areas. These annual limits are set as the annual allowable cut for each of the areas, until such time as a Forest Resources Management Plan is approved for that area.Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .

Canada's surface water frequency
Data represents surface water occurrence frequency (percentage), which describes the frequency for each grid appeared as water in the 30 years time period of 1991 to 2020. The data covers Canada’s entire landmass including all transboundary watersheds, and is at 30-meter spatial resolution. The surface water occurrence frequency is derived using the surface water model of Wang et al. (2023) from all-available monthly water data observed by the Landsat satellites (Pekel et al., 2016). Here, permanent waters are represented by 100%, and permanent land surfaces by 0%, of water occurrence for a 30-meter by 30-meter grid.References:Pekel, J.-F., A. Cottam, N. Gorelick, A.S.

Dynamic Surface Water Maps of Canada from 1984-2023 Landsat Satellite Imagery
Knowledge of the location of Earth’s surface water in time and space is critical to inform policy decisions on environment, wildlife, and human security. Dynamic surface water maps generally represent water occurrence, also referred to as inundation frequency, depicting the percentage of valid observations when water is detected at the surface. The location and duration of surface water varies from areas of permanent water with 100% inundation frequency where water is always observed, to areas of permanent land with 0% inundation where water never occurs. Between these two extremes are areas of ephemeral water that experience periodic flooding with inundation frequencies between 0-100%. National-scale dynamic surface water information was generated for years 1984-2023 at 30m spatial resolution from the historical Landsat archive over Canada. The complete dataset consists of annual water maps and derived products including inundation frequency and inter-annual wetting and drying trends calculated using per-pixel logistic regression. The complete dataset enables an assessment of the timing, duration, and trends towards wetting or drying at regional to national scales.Associated publication:https://www.sciencedirect.com/science/article/pii/S0034425722002358
Forest Inventory Ground Plots - Public Access
The Forest Analysis and Inventory Branch (FAIB) is responsible for coordinating and managing data collection and analyses from a range of different ground sampling programs that collect data on ground plots. This layer shows ground plots from the PSP and VRI programs. **Vegetation Resource Inventory (VRI):** ground samples primarily used to audit and verify key inventory attributes estimated during photo interpretation. These samples are not protected because they will not be revisited. **Permanent Sample Plots (PSP):** subjectively located fixed-area permanent plots, valued for their long-term re-measurement data to support development of growth-and-yield models in unmanaged stands across a range of stand and ecosystem types. Actual GPS coordinates are provided as protection is necessary. - Active PSPs = plot and buffer are protected from harvesting - Inactive PSPs = not protected from harvesting
A Soft-Shelled Clam (Mya arenaria) Habitat Suitability Model For The DFO Maritimes Region
The data in this layer represents habitat suitability of soft-shelled clams (Mya arenaria) in the DFO Maritimes region, and was developed using an interdepartmental approach. Substrate classification data as well as bathymetric data for the Region were used to identify potential habitat for soft-shelled clams. Substrates identified as suitable included: sand, mud, sand and mud (Greenlaw, 2022). Contours (0m and 70m) from GEBCO bathymetric data were used to isolate depths between which soft-shelled clams are present. At this stage, a polygon reflecting soft substrates from 0-70m was created as "Suitable". A "Not Suitable" layer was similarly created using the substrates: boulders, continuous bedrock, discontinuous bedrock, gravel, mixed sediment, sand and gravel.To digitally validate the model, the Regional shoreline was divided into subsectors (developed by Environment and Climate Change Canada for the Canadian Shellfish Sanitation Program). Data from DFO (clam harvesting intensity) as well as Conservation and Protection (clam harvesting infraction locations) were used to established species presence within each sub-sector. If there had been any harvesting activity, legal or illegal, in an individual subsector, it was considered "Suitable and Validated". Merged into one final product, the model includes areas that are "Not Suitable", "Suitable", as well as "Suitable and Validated" for soft-shelled clam habitat.Cite this data as: Harvey, C., Vincent, M., Greyson, P., Hamer, A.

Cultivation Intensity Index 2001
The data represents the relative cultivation intensity in the agricultural area of Alberta. Cultivation intensity refers to the frequency of cultivation associated with the following management systems: no till, conventional tillage and summerfallow. It is an estimate of the degree to which cultivation contributes to wind and water erosion. The classes shown on the map are ranked between 0 (lowest) and 1 (highest).This map was created in 2002 using ArcGIS.
