Predicted Forest Biomass and Carbon for Bruce Peninsula - Eco-District 6E-14, Ontario
Welcome to the interactive viewer for Predicted Forest Biomass and Carbon on the Bruce Peninsula. To begin using the viewer, select one of three allometric formulas from the top menu then select the map product you wish to view. From within each view, you may view a JPG of the data, download a PDF map of the data, or download a zipped copy of the actual GRID for use within a GIS.
The forest biomass predictions were created using three separate allometric formulas and a combination of field-collected tree measurements and other spatial data layers such as digital elevation models and derivatives, climate trends, and forest cover among others.
The large volume of geo-referenced vegetation data was collected during the summers of 2005-2007 through partnerships with practitioners. Statistical models of biomass were developed which were then extrapolated and mapped across the entire study area. The above-ground forest biomass data layer was the result of these extrapolations and all other data layers were derived from it according to the relevant literature. Root portions were considered to be 25% of the above-ground value and sequestered carbon was considered to be 47.5% of the biomass value, as per relevant literature.
