Aspen Bibliography

Two rather common species of giant silkrnoths of the subfamily Satumiinae (Lepidoptera: Satumiidae) occur in southern British Columbia. Both species, the Polyphemus Moth (Antheraea polyphemus [Cramer]) and the Ceanothus Silkrnoth (Hyalophora euryalis [Bois-duvall) are large and spectacular, and evoke comment from anyone who sees them. Both range northwards to at least the central Cariboo region. Three other striking species of the subfamily occur in the Peace River district of Alberta, but these moths, the Cecropia Moth (Hyalophora cecropia [Linnaeus]), the Columbia Silkmoth (H. columbia [S.L Smith]), and Glover's Silkrnoth (H. gloveri [Strecker l) have never …

Forage Quality In Burned And Unburned Aspen Communities, N.V. Debyle, P.J. Urness, D.L. Blank

Aspen Bibliography

We assessed the effects of fire on the quality of herbaceous and browse forage for elk (Gervus e/aphus) and domestic sheep in the aspen (Populus tremu/oides) forest type. Selected forage species were sampled on burned and adjacent unburned areas during the summers of the first and second years after autumn prescribed burning of three sites in southeastern Idaho. These samples were analyzed for in vitro dry matter digestibility (IVDMD), crude protein, calcium, and phosphorus. This aspen type has a highly nutritious understory irrespective of burning. We found additional improvement in forage quality as a result of prescribed burning. In the …
