Boundaries for reporting cases of COVID-19 in Saskatchewan. Areas, zones and subzones show the different geographies available; these boundaries are based on statistics Canada source geometry when possible. On August 4th 2020, the province announced it would change the method of reporting COVID-19 cases, moving from six regions based on former Regional Health Authorities to thirteen zones based on Saskatchewan Health Authority geographies. The COVID-19 Zones are made by aggregating the COVID-19 Subzones, which are based on the SHA Health Networks or aggregations thereof. The COVID-19 Areas are an aggregation of the COVID-19 Zones.  Areas, zones and subzones show the different geographies available; these boundaries are based on statistics Canada source geometry when possible.

Land cover imagery for the mixed grassland ecoregion of Saskatchewan with a resolution of 10m. Classification was based on machine learning analysis and remote sensing data of Sentinel-1 and Sentinel-2 imagery. The goal of this land cover was to distinguish native from tame grasslands, and is classified into several classes: cropland, native grassland, mixed grassland, tame grassland, water, shrubs and trees. Please also refer to the Prairie Landscape Inventory (PLI) - Mixed Grassland Accuracy raster file, which depicts the estimated level of accuracy for this this classification.

Remote Sens. 2021, 13, 4972. https://doi.org/10.3390/rs13244972The Prairie Landscape Inventory (PLI) working team of Habitat Unit in the Fish, Wildlife and Lands Branch, Ministry of Environment aims to develop improved methods of assessing land cover and land use for conservation. Native grassland, in particular, has been one of the most hard to map at risk ecosystems because of difficulty for imagery classification methods to distinguish native from tame grasslands. Improved classification methods will provide valuable information for habitat suitability, identifying high biodiversity potential and invasion risk potential. The classification map has seven (7) classes: 1. Cropland This class represents all cultivated areas with crop commodities such as corn, Pulses, Soybeans, canola, grains, and summer-fallow. 2. Native This class represents the native grassland areas of the Mixed Grasslands, which are composed primarily of native grass species such as the needle grasses (needle and thread, porcupine grass and green needle grass), wheat grasses (slender wheatgrass, western wheatgrass and awned wheatgrass) along with June grass and blue grama grass. Also includes a variety of additional grass and sedge species, forbs such as pasture sage and some non-vascular species such as selaginella or lichens. 3. Mixed This class represents one or more of the followings cases; o A higher heterogenic grassland terrain with a mix of less than 75% native or/and less than 75% tame; o Native or/and tame grassland affected by high abiotic stresses such as soil salinity and drought; o Native or/and tame grassland affected by soil erosion such as water and wind erosions; o A high disturbed area by livestock and human activities; and o A bare terrain with low vegetation cover < 50% coverage in 100 m2 area. 4. TameThis class represents the tame grassland areas that have in most cases been intentionally modified and seeded or planted with an introduced grass species such as crested wheatgrass and smooth brome. Russian wild rye is encountered typically planted in more saline areas. However, in more recent years’ horticultural varieties of various wheatgrass species have also been introduced. Alfalfa and sweet clover are the most commonly encountered introduced forb species. 5. Water This class represents one of the following hydrological forms: o Lakes; o Rivers; o Water ponds; o Streamflow; o Dugouts; and o Lower elevations in irrigated areas. 6. Shrubs (Modified from ISO 19131 Annual Crop Inventory – Data Product Specifications, Agriculture and Agri-food Canada, 2013.)This class represents the predominantly woody vegetation of relatively low height (generally ±2 m). This class may include grass or wetlands with woody vegetation, and regenerating forest. 7. Trees (Modified from ISO 19131 Annual Crop Inventory – Data Product Specifications, Agriculture and Agri-food Canada, 2013.)This class represents predominantly forest areas such as: o Coniferous trees; o Deciduous trees; o Mixedwood area; and o Other trees > 2 m height.

Predictive ecosite map of Saskatchewan's provincial forests and adjacent parks within the boreal plain, boreal shield and taiga shield ecozones: version 01. Download: Here The Predictive Ecosite Map of Saskatchewan is based on the classifications of McLaughlan et al. (2010). This version (v01) is an interim proof-of-concept product and is not considered highly accurate or finalized. Ecosite prediction accuracy is anticipated to between 40% and 65%, depending on geographic location. For the boreal plain ecozone, ecosites were derived using a random forest imputation with the yaImpute package in R and mapped by L. Gelhorn (2014-07-24). Pixel values presented here are prefixed with a 2. Non-forest / non-water pixels are often assigned a BP28 ecosite code (228). For the boreal shield and taiga shield ecozones, ecosites were derived using a random forest imputation with the yaImpute package in R and mapped by S. Oldford (2019-11-20). Pixel values presented here are prefixed with a 3 and a 4, respectively. In the case of the taiga shield ecozone, there were limited sample plot data. To increase the sample size for modelling, the majority of taiga shield ecosites data are combined and modeled with boreal sheild ecosites using the ecozonal synonyms of McLaughlan et al. (2010). Ecosites TS01 (401), TS04 (404) and TS17 (417) were modeled as such because no ecozonal synonyms exist. This map is clipped to the Saskatchewan provincial forest and adjacent park boundaries. Water bodies are masked according to the 2015 Landcover Map of Canada of White et al. (2017) and have a pixel value of zero (0). References: McLaughlan, M.S., Wright, R.A. and Jiricka, R.D. (2010).

Upland Forest (FOR): Land that is currently growing, or capable of supporting, a treed upland forest community. Moisture regimes are dry through very moist. Shrubby Upland (SUL): Uplands containing a persistent cover of non-merchantable hardwood tree species and shrubs. This class does not include upland forest types expected to succeed to a treed community following disturbance. This class is distinguished from shrubby wetland on the basis of moisture regime: moisture regimes are dry through very moist. Treed Wetland (TWL): Wetlands containing ≥ 10% tree crown cover, typically greater than two metres tall in absence of recent disturbance. This class includes treed bogs, treed fens, and treed swamps. Moisture regimes are moderately wet to very wet. Shrubby Wetland (SUL): Wetlands and riparian areas containing a persistent cover of non-merchantable hardwood trees and shrubs. This class includes shrub swamps, shrubby bogs and fens. It does not include upland forest types expected to succeed to a treed community following disturbance. Open Wetland (OWL): Wetlands dominated by mosses, grasses, sedges, and small herbaceous plants, often associated with small areas of open water. This class includes marshes and open or graminoid bogs and fens. Moisture regimes are moderately wet to very wet. Treed Rock (TRK): Areas of exposed bedrock interspersed with trees, where tree crown cover ≥ 10% and < 30%. Areas of partially exposed bedrock where crown cover ≥ 30% are classified as upland forest. Areas of exposed bedrock where crown cover <10% are classified as rock or sand. Rock or Sand (RKS): Naturally occurring, barren or exposed, rock, sand, or gravel deposits with <10% of the area occupied by trees. Grass (GRS): Uplands containing a persistent cover of grass and herbs. This class is differentiated from open wetland on the basis of moisture regime. It does not include upland forest types expected to succeed to a treed community following disturbance. Agricultural Land (ALA): A land classification for lands which are cultivated for growing crops, including pasture, orchards and abandoned fields. Lands designated as provincial forests cannot be assigned this classification, however this class of land may be found within or adjacent to the mapped boundaries of provincial forests. Anthropogenic Unclassified (AUC): Areas which are non-forested due to vegetation clearing and/or building. This includes built-up areas, camps, roads, railways, mines, utility corridors, gravel pits, and similar human-caused disturbances. With the exception of permanent roads used to access timber, timber harvests are not included as anthropogenic unclassified.
