Objective: To assess impacts to the local saw whet owl population caused by construction of the Mountains To Sea Trail and by increased levels of human activity as a result of trail use. Attempted to document population density, territory placement, and reproductive activity.

Results summary:
- Results suggest that barred owl activity and certain types of human activity may discourage saw whet owls from locating their breeding season territories where these disturbances are present.
Comments:
- Year 1 study of planned three year study. I do not know if the subsequent, post-trail construction study was implemented.
- Density - Estimates based on area along transect encompassing maximum detection distance (i.e., distance within which detection is thought to be 100%).
- Territory spacing in relation to disturbances- Disturbance categories included motor vehicles, daytime human pedestrian activity along trails and parking areas, night time human activity at camping and residential areas, and barred and great horned owl activity.
