Get mapping data related to the Northwest Greater Toronto Area Transmission Corridor Identification Study. In June 2019, the Ministry of Energy, Northern Development and Mines along with Ontario’s electricity system planner, the Independent Electricity System Operator, launched the Northwest GTA Transmission Corridor Identification Study to identify an appropriate corridor of land for use by future power lines if and when the need arises.

Non-government agency Nature Reserves are polygon features describing lands held by nature trusts and other non-government agencies for the purpose of nature conservation. We are no longer updating this data. It is best suited for historical research and analysis. This product requires the use of geographic information system (GIS) software.

Get data on the results of a community led planning process to sustain the natural environment for the Kawartha Lakes region. This dataset represents the results of a community led planning process to sustain the natural environment across the landscape. A collaborative team of individuals representing governments, stewardship councils, conservation organizations, local industry, private landowners and First Nation communities worked together to identify and map natural heritage features and the connections between them. The data package includes: * spatial data * project reports * presentation materials The data has been made available to inform and support: * land use planning * resource management * stewardship and restoration projects * priorities for conservation land acquisitions * priorities for inventory programs and research Please visit [http://www.kawarthasnaturally.ca/](http://www.kawarthasnaturally.ca/) for more information about this project.

This spatial dataset represents the locations of aquatic resource area (ARA) line segments derived from corresponding line features in the Ontario Hydro Network. ARA line segments may represent a portion of a water body or an entire water body (such as a lake, river or stream). Attributes for each location may include: * physical characteristics such as water temperature and depth * fish species The ARA data classes are the authoritative source for generic spatial data related to fish species in Ontario. The data can be used for: * forest and fisheries management planning * municipal planning * natural heritage and land use planning * issuing work permits under the [Public Lands Act](https://www.ontario.ca/laws/statute/90p43), 1990 * issuing licenses under the [Fish and Wildlife Conservation Act](https://www.ontario.ca/laws/statute/97f41), 1997 * fulfilling public information requests There are additional sensitive data related to provincially tracked species and species at risk that are not available as part of this open data package. Distribution of sensitive species data is approved on a need-to-know basis. Requests should be sent to [geospatial@ontario.ca](mailto:geospatial@ontario.ca).

Natural cover includes areas that have been mapped as woodlands (including plantations and hedgerows), wetlands and other rare vegetative cover communities. Data here represent areas outlined in the Lake Simcoe Protection Plan Policy 6.48 (June 2011). This product requires the use of geographic information system (GIS) software.

Data show where pathogens - fungal, bacillial or viral - have caused damage by reducing growth rates, tree vigor or have killed trees. Examples of forest diseases include White Pine Blister Rust, Armillaria Root Rot etc. The Government of Ontario tracks forest damage events to help proactively manage the detrimental effects to our forests. We monitor the threat and spread of invasive forest pest insect species in Ontario. The data is also important to the Forest Management Planning process in calculating timber volume loss within affected areas. This product requires the use of geographic information system (GIS) software.

This dataset is used to: * assess biodiversity levels * define seed zones * map ecosystem types * set targets for the identification of natural heritage systems

This data covers the entire Far North from 2005-2011. The data is provided in both grid and vector formats. It is broken into layers that cover UTM zones 15, 16 and 17. Layers representing each level of the classification hierarchy described in the data specs have been provided: * class * group * section Can be used to create a consistent map to meet regional - to landscape level analysis (1:100,000).

## Get data on boundaries of local climatic areas used for forest fire weather forecasting. This dataset shows the boundaries of administrative areas used for forest fire weather forecasting. North of the French River, boundaries correspond closely with Environment Canada’s areas for public weather forecasting. South of the French River, 25 Environment Canada areas are combined into six larger areas for provincial forecasting.

A synthesis of available background data on the types and extent of anthropogenic disturbances on this shoreline as a well as to understand the types and amount of remaining natural shoreline features.
