Abstract:

Twenty—seven flammulated owl (Otus flammeolus) surveys were conducted on the Nez Perce National Forest from 11 May to 10 July, 1992. One hundred ten singing male flammulated owl observations were recorded on the Red River and Salmon River Ranger Districts from 15 May to 10 July, 1992 (59 on the Salmon River District and 51 on the Red River Ranger District). No flammulated owls were recorded on the Clearwater Ranger District. Owl density estimates ranged from .28 singing male flammulated owls per 40 ha for the Mackay Bar survey route on 17 May and 18 June, to 1.13 singing male flammulated owls per 40 ha for the Indian Creek survey route on 22 June. Habitat data indicated stand composition is dominated by ponderosa pine (Pinus ponderosa) of all age and size classes creating multi—layered stands with moderately open canopies (52% canopy cover, SD=30). Ponderosa pine dominated 84% of the habitat plots. Ninety—two percent of habitat plots had three canopy layers.
