These ΒΌ hectare plots were set-up in 1985 and 1986 by the Ontario Ministry of Environment and have been assessed annually between 1986 and 2006, with the exception of 1992 and 1993. The core monitoring component of the OFBN is the Decline Index, an evaluation of the crown condition of all trees within each forest monitoring plot. The proportion of dead branches, chlorotic leaves and undersized leaves on a tree drives a weighted mathematical model to calculate a Decline Index score. This score is an estimation of the tree's health. Monitoring average plot Decline Index scores over time can provide an indication of how the hardwood ecosystem is responding to environmental stressors, such as long-range air pollution and climate change.The formula for calculating the Decline Index is:
DI = DB + ([100-DB]/400) * (UL + ST + SL/2)
Where:
DI = Decline Index
DB = % Dead branches
UL = % Undersized leaves
ST = % leaves with strong chlorosis
SL = % leaves with slight chlorosisThe data set was developed to monitor and assess the health of Ontario's sugar maple-dominated hardwood forests across southern and central Ontario as a function of regional air quality and more recently climate changeOntario Ministry of the Environment, 2009, Ontario Forest Biomonitoring Network 2009OFBN1OFBN1vector digital data\\gisdata1\gis_projects\GIS_CENTER\Data_Dissemination\OFBN\OFBN1.shpMean Decline Index Data Set [unpublished] ground conditionJuly 1990unknownSeptember 2006Annually-89.561052-74.42219148.29350342.683244-89.561052-74.42219142.68324448.293503nonenoneShapefileTerrestrial Assessment Unit, Environmental Monitoring and Reporting Branch, Ontario Ministry of the EnvironmentOntario Forest Biomonitoring Network co-ordinatorMicrosoft Windows XP Version 5.1 (Build 2600) Service Pack 2; ESRI ArcCatalog 9.1.0.780OFBN1-89.561052-74.42219148.29350342.6832441-89.561052-74.42219148.29350342.6832441enFGDC Content Standards for Digital Geospatial MetadataFGDC-STD-001-1998local timeChris Charron, Chris WatsonOntario Ministry of the Environment, Environmental Monitoring and Reporting Branch416-314-504720090304http://www.esri.com/metadata/esriprof80.htmlESRI Metadata ProfileISO 19115 Geographic Information - MetadataDIS_ESRI1.0datasetDownloadable Data0.0030.003Users must agree to the disclaimer expressed on the MOE Data Download page:

The forest monitoring plots are stored as points and are geographically referenced by GPS coordinates that have been generalized to approximate locations. Coordinates identified in the shapefile are randomly placed within 500 metres of ground truth. Original geographic data has been confirmed with a Garmin GPSmap 60CSx GPS unit to be correct to within 2m. ArcInfo/ArccmapMarch 2009All data was compiled and quality control checked by the Terrestrial Assessment Unit, Environmental Monitoring and Reporting Branch, Ontario Ministry of the Environment.
The Decline Index data was collected by forest service contractors to the Terrestrial Assessment Unit.

Dataset copied.O:\GIS_CENTER\Data_Dissemination\OFBN\OFBN-rand20090304The Decline Index component of the OFBN are assessed and scored by forestry professionals for each tree within a forest monitoring plot. The Decline Index scores are recorded on field data sheets and later transferred to an electronic format. Each score is quality control checked by Terrestrial Assessment Unit staff by comparing the electronic data to the original field sheets. The Decline Index for each tree is calculated using the equation referenced above under "How is the Decline Index calculated?". The average forest monitoring plot Decline Index is calculated by taking the mean of all tree decline index scores within the plot.Decline index data has been collected between 1986-1989 period however the data has not undergone sufficient quality control checking to be certified and published for general use.
All data has undergone precise quality control checking against the original field sheets by Terrestrial Assessment Unit staff.Data has not been included for forest monitoring plots for years where the Decline Index assessment was not conducted (e.g., 1992 and 1993).The geographic data was collected in the field using a Garmin GPSmap 60CSx Global Positioning System (GPS) unit. Location coordinates were averaged until an error of 2m or less was reached. Plot centre coordinates were randomized within a one hectare area to prevent disturbance of the forest monitoring plots.
