Predicted Forest Above-ground Biomass for Bruce Peninsula (t/ha) - biomass estimates based on Lambert et al., 2005 Allometric Formulas (Mean Filtered)
| 
| Above-ground biomass estimates for the Bruce Peninsula area created using the Lambert et al., 2005 allometric formulas. For each pixel in the grid, biomass per hectare within a three pixel by three pixel moving window (focal mean) were derived. This window was selected as it reduces potential effects of image misregistration, substitutes for spatial dependence and smoothes. Difference between the original and this grid was performed, and it was found to be negligible when 3x3 window was applied. Estimates of biomass for this grid are presented in tonnes/hectare.
Mapped modelling results can be used to inform and support various aspects of landscape conservation, management and planning in the area. Specifically, the mappings can be used to support future natural heritage systems planning, biodiversity conservation, and species at risk habitat protection initiatives in this area. This data may also be useful for carbon sequestration models or in climate analysis work.
Through partnerships with practitioners, a large volume of geo-referenced vegetation data was collected during the summers 2005-2007. Thie field collected tree measurements along with other spatial layers (e.g., digital elevation model and derivatives, remote sensing imagery - Landsat and Quickbird, etc) were used to develop statistical models of biomass. The models were extrapolated and mapped across the entire study area.
