The objective of this research is to determine hydrometeorologic thresholds for the initiation of shallow landslides that can be used as guidelines for forest operation shutdowns. Three principal sources of data were used for this research: The first is a dataset of landslide dates and locations, which was compiled by Ministry of Forest staff and tree farm licensees. The second source is climatological and hydrological data collected for antecedent rainfall, rainfall intensity and stream discharge from Environment Canada and the Ministry of Transportation. Finally, meteorological data were gathered for 51 rainstorms that were known to have triggered landslides.
