This data summarizes forest management activities that occur in Ontario’s Crown forests each year. Forest management activities in each management unit are planned and approved through forest management plans. Each year, forest managers report on the activities conducted in a management unit. The data from management unit annual reports is consolidated into provincewide data and statistics.

Note: This data has been replaced by the Ontario Watershed Boundaries (OWB). We are no longer updating this data. It is best suited for historical research and analysis. A watershed, also known as a catchment basin, includes all land that is drained by a watercourse and its tributaries.

The Ontario Stewardship Program has established Stewardship Councils across Ontario. Ministry of Natural Resources and Forestry staff no longer directly administer and support Ontario Stewardship Councils. Community-based partners and stakeholders now independently administer Stewardship Councils. We are no longer updating this data.

Geographic information for Ontario Health Regions (OH Regions) and Local Health Integration Networks (LHINs). OH Regions and the LHINs found within them are funded by the Ministry of Health to plan, coordinate and fund local health care services for improving patient experience and access to care. The LHIN boundary file is maintained by Statistics Canada. A link is provided to the Statistics Canada website where you can download the LHIN boundary file in a variety of formats.

This database includes information on OPP Host and Satellite Detachments that comprise each cluster within the province, broken down by OPP Regional Structure. It lists all General Headquarters Bureaus and the Commands they are associated with. *[OPP]: Ontario Provincial Police

This spatial data identifies breeding zones used by forest managers and forest genetic associations to manage provincial forest genetic assets. The data: * shows the boundaries of breeding zones * identifies the primary or target species within each zone Species are associated with certain breeding programs, seed orchards and progeny (descendant) testing installations.

Fish stocking data for recreational fishing purposes. Contains: * stocking data for the past 10 years for species where the purpose of the stocking event was to promote recreational fishing. This is a subset of data from the fish stocking information system. This data can also be obtained through the Fish ON-Line application.

Hazardous forest types for wildland fire means forest types assessed as being associated with the risk of high to extreme wildland fire. This data is intended to help inform where further assessment is required and is to be used in conjunction with guidance from the Ministry of Natural Resources and Forestry .

Ontario's Crown forest is divided into geographic planning areas, known as forest management units. Most of these units are managed by individual forest companies under a Sustainable Forest License. A forest management unit is identified by an assigned official name (e.g., Black Spruce Forest) and a unique numeric code. Before any forestry activities can take place in a management unit, there must be an approved forest management plan in place for each management unit.

The Ontario Forest Biomonitoring Network (OFBN) monitors the health of mixed hardwood forests across southern and central Ontario. The data set includes: * Individual Tree Data: Decline Index and other measurements of visual stress symptoms of each tree within 111 plots * Decline Index: The Decline Index is a weighted average of tree stress symptoms (percent dead branches, percent slight or strong chlorosis (pale green-yellow leaves) and percent undersized leaves). Averaged for hardwood trees found within each of the 111 plots in each year. * Invasive Plant Species Presence Data * Salamander Data: numbers of individuals of salamander and other animal species in 14 plots * Tree Regeneration Data: monitors numbers of tree seedlings/saplings in 102 plots * Woody Debris Data: amount of woody debris on ground in 102 plots
