  • Quetico Park Inventory

    Quetico Park has been largely protected since the early 1900s and represents a forest that has been allowed to function with relatively low influence from man. The Dog River-Matawin Forest has been managed for nearly the same length of time for timber production. Since the mid 1980s the forest has been managed under forest management agreements of one form or another. Between these two land units the level of silviculture following disturbance ranges from null (Quetico) to very intensive, which is one of the main reason this area has been chosen for the Legacy Forest. To use this full range similar datasets are required for the entire area (e.g. forest cover). Quetico Park has not been managed for timber at all since the 1970s so it has been unecessary to update the forest inventory put it into digital format. One of the main components of the Legacy Forest project is to utilize modern imagery and analysis techniques to create an up-to-date digital forest cover layer for Quetico that is comparable to the Dog River-Matawin Forest.

    Remotely sensed data sets spanning both the Dog River-Matawin Forest and Quetico Provincial Park will be segmented with appropriate software tools using knowledge-based software classification algorithms, textural/spatial incorporation tools and heads-up digitizing. The intended application of the resulting data sets is to supply a common base of vegetation classification for the entire Legacy Forest.

    Landsat 7 ETM satellite imagery for the entire Legacy Forest has been acquired from the summer of 2002. This will be used at the most general level as a consistent base dataset for assessment of the entire project area. Colour-infrared photography at 1:30000 was flown in late August for all of Quetico Park (example below). Colour-infrared offers better distinction of tree species (particularly hardwoods) over tradition black-and-white photography. These photos will be scanned and ortho-rectified for use with digitial photogrammetry tools that enable efficient and consistent transfer of interpreted data to a spatial database. To help drive the interpretation of these photos approximately 200 Large-Scale Photo (LSP) plots were flown using a helicopter boom system by Wisk-Air Helicopters. The boom allows for a pair of photos to be acquired in stereo at a scale that provides very detailed stand-level information (see example below).
