A trapline area is a polygon feature that identifies a ministry-regulated boundary used to administer traplines and fur management programs.

The dataset represents prominent linear (man-made or natural) features including: * cliffs * dykes * fences * walls * hedgerows * feature outlines * racetrack centre lines * racetrack edges We are no longer updating this data. It is best suited for historical research and analysis.

The Forest Resources Inventory (FRI) provides information about tree species, including: * composition * height * age * density Ontario’s forest resource inventories allow us to support resource management and land use decisions, and help sustain healthy, natural environments. Forest resource inventories for each forest management unit are legally required under the [Crown Forest Sustainability Act (1994)](https://www.ontario.ca/laws/statute/94c25). Every 10 years, the ministry creates a new forest management plan where inventory data is updated and must be compliant with the requirements detailed in the Act. Ontario’s FRI is also used to meet provincial, federal, and international reporting requirements. These draft FRI Packaged Product data sets are being provided for the purpose of consultation and product development. The number of attributes and the algorithms used to generate the attribute as well as the data formats will change over time and should not be considered the final version. A final version of the structure and content of the FRI will be made available after the required consultations are complete. Data sets will be made available for each Forest Management Unit as they are produced. For more information on the FRI please see: [https://www.ontario.ca/page/forest-resources-inventory](https://www.ontario.ca/page/forest-resources-inventory)

This dataset shows 1:250,000 scale faults/lineaments of the Precambrian Shield area of Saskatchewan. This dataset shows the 1:250,000 scale bedrock geology faults/lineaments of the Precambrian Shield area of Saskatchewan. The faults/lineaments layer has been merged from the 1:250,000 scale Compilation Bedrock Geology map series.  **Please Note – All published Saskatchewan Geological Survey datasets, including those available through the Saskatchewan Mining and Petroleum GeoAtlas, are sourced from the Enterprise GIS Data Warehouse. They are therefore identical and share the same refresh schedule.

Historical Oil Fields are subsurface accumulations or 'pools' of crude oil designated as such for the purposes of the Oil, Gas and Salt Resources Act. This product requires the use of geographic information system (GIS) software.

Southern Ontario Land Resource Information System (SOLRIS) is based on Ministry of Natural Resources' Ecological Land Classification (ELC) for southern Ontario (Lee et al, 1998). It is a land use inventory that supports a number of key Provincial initiatives including Source Water Protection, Natural Spaces, Biodiversity Conservation and State of Resources Reporting. The data covers the date ranges from 1999-2002 and 2009-2011.

Fish consumption advisories for Ontario's lakes and rivers are available in the Guide to Eating Ontario Fish. The zip file below includes a GIS shapefile of all lake/river locations and a text file of all consumption advisory data from the current edition of the Guide.

Fish Culture Operation MNR identifies the locations of the Ontario Ministry of Natural Resources (MNR) fish culture stations (or hatcheries) and sub- stations. The data set outlines their property boundaries. This product requires the use of GIS software.

The ministry monitors air pollution levels and issues smog advisories when there is strong likelihood that widespread, elevated, and persistent smog levels are expected. This dataset provides a comprehensive summary in excel file format. The dataset includes the forecasts for the regions where a smog advisory was issued and the duration of the advisory for each year. **The Smog Advisory Statistics page has been archived and is no longer updated.** See [Air Quality Alerts](https://data.ontario.ca/dataset/air-quality-alerts) for current updates

The Big Picture 2002 is a legacy geographic information system (GIS) based landscape analysis. It is a partnership between the Nature Conservancy of Canada and the Ministry of Natural Resources’ Natural Heritage Information Centre. Many digital layers covering the Mixedwood Plains ecozone plus a portion of the Ontario Shield ecozone were compiled for this analysis. These layers include: * evaluated wetlands * forest cover * old growth forest * rare species and communities * waterbodies and watercourses * parks and protected areas * Areas of Natural and Scientific Interest (ANSIs) The data layers are overlaid in a GIS system and points are assigned to the features in each layer according to their conservation value. Core natural areas were identified by a combination of minimum size and a minimum point score per pixel. Potential linkages between these cores were computed by assigning scores to the landscape surrounding the cores based on the probable resistance to wildlife movement. We do not currently use this methodology for similar analyses.
