Abstract: Yellowstone and Grand Teton National Parks have been zoned to allow certain natural fires to burn until they self-extinguuish. The effect of these natural fires on avifauna in the two parks is reported in this paper. Breeding bird populations in burned lodgepole pine or spruce-fir-lodgepole pine forests of the following post-fire ages are analyzed: MODERATE BURN 1 2, 3 years; SEVERE BURN 1, 2, 3, 5, 7, 11, 13, 17, 25, 29, 43, 44, 45, 57, 61, 111, 115, 300, 304 years; UNBURNED SPUCE-FIR WITH SOME LODGEPOLE PINE, and UNBURNED SPRUCE-FIR. Highest populations and greatest biomass occurred from 5-29 years post-fire. Bird density, species composition, and diversity on moderately burned spruce-fir-lodgepole were more like those on unburned spruce-fir than on other seral stages. Greatest biomass of air-soaring, foliage-seed, timber-drilling, ground-insect, and ground-seed feeding categories occurred where the forest canopy had not closed. Biomass of foliage-insect and timber-searching was greatest where the forest canopy had closed. Canopy closure affected avifauna more than fire did.

| ABSTRACT | Yellowstone and Grand Teton National Parks have been zoned to allow certain natural fires to burn until they self-extinguuish. The effect of these natural fires on avifauna in the two parks is reported in this paper.
Breeding bird populations in burned lodgepole pine or spruce-fir-lodgepole pine forests of the following post-fire ages are analyzed:
MODERATE BURN 1 2, 3 years;
SEVERE BURN 1, 2, 3, 5, 7, 11, 13, 17, 25, 29, 43, 44, 45, 57, 61, 111, 115, 300, 304 years;
UNBURNED SPUCE-FIR WITH SOME LODGEPOLE PINE, and UNBURNED SPRUCE-FIR.
Highest populations and greatest biomass occurred from 5-29 years post-fire. Bird density, species composition, and diversity on moderately burned spruce-fir-lodgepole were more like those on unburned spruce-fir than on other seral stages. Greatest biomass of air-soaring, foliage-seed, timber-drilling, ground-insect, and ground-seed feeding categories occurred where the forest canopy had not closed. Biomass of foliage-insect and timber-searching was greatest where the forest canopy had closed. Canopy closure affected avifauna more than fire did. |
