About this dataset

Miscellaneous events are often the result of the cumulative impact of a combination of abiotic, insect and disease agents or events.  For example, Aspen decline where repeated infestations of Forest Tent Caterpillar, are combined with several seasons of prolonged drought. 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 must be taken into account when comparing information from this data class to other NRVIS layers that have a higher spatial accuracy (e.g.:Forest Cover). Otherwise, misleading results will be derived whenever this information is subjected to analysis. This NRVIS data class accommodates history for events spanning several years which includes overlaps. Users should request and/or sort out individual events through the 'Year of Event' ,'Event Name' and 'Forest Damage Ranking' attributes in order to prevent clutter.

Research Point

A research point is a feature representing single coordinate or point based locations, where some form of research observation, test, trial, measure, or monitoring activity has, or will take place.  The mapped features are generally small in extent (for example, soil water table monitor, tree cavity nest), and can be used to represent the locations of sampling techniques (for example, basal area prism sweep). This data class is one of three primitive data classes: Research Point (RESPOINT) Research Line (RESLINE) Research Polygon (RESPOLY)   Status:  On going: data is continually being updated Maintenance and Update Frequency: As required  Contact Calvin Julie, Natural Resources Information Unitcalvin.julie@ontario.ca  Note Additional features licensed under the Ontario Geospatial Data Exchange (OGDE) Agreement are available to members of the OGDE for professional, non-commercial use only.

Site Region

Site Regions and Site Districts of Ontario represent an early ELC system originally developed by Angus Hills (1959 and later revisions). This dataset was revised by the ELC Working Group in 2000 to better reflect new information and new technology, while maintaining Hills's original concepts. For further information on the rationale for the revisions, refer to Ecoregions of Ontario Modifications to Angus Hills Site Regions and Districts, Revisions and Rationale (Crins and Uhlig 2000), or the Ecological Land Classification Primer (Crins 2007).

Site District

Site Regions and Site Districts of Ontario represent an early Ecological Land Classification (ELC) system originally developed by Angus Hills. This dataset was revised by the ELC Working Group in 2000 to better reflect new information and new technology. The Site Regions of Ontario was used for descriptive, planning, and resource management purposes. This upper level in its hierarchy was most useful for provincial and regional roll-ups of data and for strategic planning. Site Districts of Ontario is a more detailed lower (finer-scale) level of the hierarchy, and was more useful for detailed resource management prescriptions and other local and site planning applications. This layer is designed to be used as a spatial selection tool and as a background layer suitable for overlay and or intersection with numerous scales or current hydrologic data.

Historical Fire Management Zones

This dataset shows the boundaries of the province's six fire management zones that existed prior to 2014 in which most forest fires received the same type of response. These management zones were based on: Common forest and forest fire management objectives land use density of values at risk fire load forest ecology The 2014 Wildland Fire Management Strategy moved from a zone-based approach to one where each wildland fire is assessed and receives an appropriate response according to the circumstances and condition of the fire.  Additional DocumentationFire Management Zone - Data Description (PDF)  Fire Management Zone - Documentation (Word)   StatusCompleted: Production of the data has been completed  Maintenance and Update FrequencyAs needed: Data is updated as deemed necessary  ContactAviation, Forest Fire and Emergency ServicesAFFES.GIS@ontario.ca

Forest Inventory and Analysis

Status and trends on U.S. forest location, health, growth, mortality, and production, from the U.S. Forest Service's Forest Inventory and Analysis (FIA) program. The Forest Inventory and Analysis (FIA) dataset is a nationwide survey of the forest assets of the United States. The FIA research program has been in existence since 1928. FIA's primary objective is to determine the extent, condition, volume, growth, and use of trees on the nation's forest land. Domain: continental U.S., 1928-2018 Resolution: plot-level (irregular polygon) This dataset was curated and brought to Azure by CarbonPlan.
