From February 17 to March 23, 2004, the Nimpkish Owl Survey was conducted on TFL 37 on northern Vancouver Island by WRM Consulting, Ltd. for CanFor. The 2004 owl inventory was part of CanFor's ongoing commitment to monitoring the effectiveness of ecosystem-based management. Surveys were split into two phases for 2004 due to funding sources. Both phases targeted all 5 owl species known to occur in the Nimpkish Valley. Both phases utilise a series of 10 road transects. Surveyors listened for voluntary owl calls for two minutes, then played a series of three northern pygmy owl recordings on a portable tape deck, with 30 seconds of silence in between, followed by a further three minutes of listening. 36 owls in total were detected at the 190 points surveyed during Phase I including two northern pygmy-owls, nine northern saw-whet owls, 19 western screech-owls, five barred owls and one great horned owl. 4 of the 36 owl detections were voluntary and 32 were responses to tape playback. During phase II, there were 19 owls detections at 110 survey points. Four saw-whet owls, 12 western screech-owls, and 3 barred owls were detected.
