Introduction to Global Forest Watch Canada Began mapping IFL in Canadain ~ 2000, based on earlier work by Global Forest Watch Russia To support the stewardship and conservation of Canada's remaining forests, by providing decision makers and civil society with timely, accurate information on their location, state, and change. In particular, this mission includes monitoring development activities using sophisticated GIS and remote sensing technologies. |

National datasets we create: Cumulative Access [AnthropogenicDisturbance to ~2006] Change Analysis [~1990 – 2000] National Hydropower Reservoirs [2007] Intact Forest Landscapes [up to ~2006] Other datasets: Industrial Tenures (for example: forest tenures/mills) First Nations Lands |

GFWC Intact Forest Landscape Mapping MethodologyHow do we map Intact Forest Landscapes? Based on GFW Russia Methodology, binary classification as intact/disturbed. We first assume that all forests are intact. Existing datasets Eliminate existing anthropogenic disturbances based on readily available datasets (for example: roads, reservoirs) Landsat data Eliminate all visible anthropogenic disturbances seen medium resolution satellite imagery (for example: clearcuts, oil well sites) Fire was not included as anthropogenic change Disturbances were buffered by 500m – 1000m |

Process of choosing conservation valuesDetermining priority areas within IFLs How do we choose values EXPERT PANEL [DELPHI TECHNIQUE] How good is the product? Depends on: What datasets are available The scale/coarseness of the data Who chooses the conservation values Geographical boundaries Political opportunities How the conservation values are ranked [show a comparison of the effects of changing conservation values ranking] |

Potential Conservation ValuesList of datasets that we have available in Canada: Intact Forest Lanscapes Caribou/ caribou habitat Carbon storage: Terrestrial (Soil Organic Carbon) Assessment of Representation (AoR) Aquatic density Rainforests (Boreal) Free-flowing major rivers Proximity/adjacency to existing Protected Areas Old growth forests (Forest age) Wetlands Carbon sinks (Net Biome Productivity) Tree height Focal species: Grizzly Focal species: Wolverine Species Diversity |

Conservation Values and Protected Areas in CanadaIs the allocation of lands and freshwaters to protected areas achieving naturalness, presumably a key conservation objective of protected areas? Definition of naturalness |

Conservation Values and Protected Areas in CanadaAnthropogenic access within Canada’s Protected Areas is approximately 31% of that within all of Canada (5.3% versus 17.6%), meaning that Canada’s protected areas are much more “natural” than Canada as a whole. Only 5.3% of Canada’s protected areas are anthropogenically accessed, compared to that of surrounding buffer areas at 48.6%: buffer areas surrounding protected areas are almost 10 times more accessed than the protected areas they surround. |

Lessons for GFWCIntact Forest Landscapes have been, in Canada, a powerful but insufficient , conservation advocacy tool. There has been urgent need to: Map smaller IFLs than 50,000 ha Identify high priority sites for conservation within IFLs Identify both industrial near-future threats to IFLs and political opportunities to conserve IFLs. |
