This study is a synthesis of the available ethnographic and relevant archaeological data pertaining to the Native American groups who formerly occupied the upper Rogue River drainage of southwestern Oregon. The information presented in this synthesis concerns the material, social and religious aspects of aboriginal life as practiced by the...
Determining the mechanisms responsible for the success of invasive species is critical for
developing effective management strategies. Artificially draining managed wetlands to maintain natural
ephemeral conditions is a common practice in the Pacific Northwest and is assumed to kill invasive American
bullfrog (Lithobates catesbeianus) larvae, which typically overwinter in permanent...

Equations for predicting total height as a function of diameter at breast height are presented for 17 tree species from southwest Oregon. Because basal area and site index often influence tree height, additional equations are presented which may include either or both of these as independent variables. Equation coefficients were...
Following high-severity fire, forest succession may take alternate pathways depending on the pattern of the fire and any secondary disturbances during early stand development, with lasting consequences for ecosystem function. The objectives of this research were to quantify: (1) early postfire regeneration as influenced by the spatial pattern of a...
Experiments were conducted under field and greenhouse conditions
to investigate the effects of chlorpropham (isopropyl mchlorocarbanilate)
on vegetative and reproductive development in
Chewings fescue (Festuca rubra L. subsp. commutata Gaud.) and to
determine the time of induction and initiation under natural conditions.
Chewings fescue was found to be very susceptible...
Fire is a fundamental disturbance that drives terrestrial and atmospheric carbon dynamics. Previous studies have quantified fire effects on carbon cycling from local to global scales but have focused nearly exclusively on high-severity, stand-replacement fire. Since 2002, variable-severity wildfires have burned more than 65 000 ha across the east slope...
A ground-breaking study of the relations between the fur traders of Fort Nez Perce's and the Indians of the region, primarily Cayuse, Wallawalla, Umatilla, and Nez Perce. Existing literature on this region has focused on the white explorers, the fur traders, and the settlers; Chiefs and Chief Traders offers a...
