Stereo photo series for quantifying forest residues in coastal Oregon forests: second-growth Douglas-fir--western hemlock type, western hemlock--Sitka spruce type, and red alder type

Creator:

Ottmar, Roger D. and Hardy, Colin C.

Abstract:

A series of stereo photographs displays a range of residue loadings for cleancut units in three general forest types common to coastal Oregon forest lands: Douglas-fir--western hemlock (second-growth), western hemlock--Sitka spruce, and red alder. Postburn residue levels are also represented for the Douglas-fir--western hemlock, and red alder types. Information with...

Historical and current forest landscapes in Eastern Oregon and Washington. Part 2. Linking vegetation characteristics to potential fire behavior and related smoke production

Creator:

Huff, Mark H., Ottmar, Roger D., Alvarado, Ernesto, Vinnanek, Robert E., Lehmkuhl, John F., Hessburg, Paul F., and Everett, Richard L.

Abstract:

We compared the potential fire behavior and smoke production of historical and current time periods based on vegetative conditions in forty-nine 5100- to 13 500-hectare watersheds in six river basins in eastern Oregon and Washington. Vegetation composition, structure, and patterns were attributed and mapped from aerial photographs taken from 1932...
