The objective of this report is to describe the current increase in Douglas-fir tussock moth (Orgyia pseudotsugata McDunnough) activity in northern Idaho and Montana. The report also relates current conditions to historical and future trends and larger scale increasing tussock moth activity in surrounding western states.
This Environmental Assessment (EA) will address the Klamath Falls Resource Area proposal to
upgrade the existing concrete stream ford on the CCC road (no. 41-14E-11) where it crosses Barnes
Valley Creek at T39S, R14 ½ E, Sec. 22 (see attached map, figure 1).
The proposed construction project would be done...
Young trees (those with a trunk diameter of less than 6 inches) can benefit greatly from regular applications of fertilizer. Research has shown that when these trees receive nitrogen fertilizer, they grow faster, develop a denser canopy, and stay green longer into the fall.
Many garden and landscape plants
are susceptible to one or more plant
diseases. Diseases can reduce the yield
of fruit and vegetable crops and disfigure
ornamental trees, shrubs, and
flowers.
The cereal leaf beetle (CLB), a serious pest of cereals and grasses, was found in Oregon in 1999. As a result, California has imposed a quarantine on certain agricultural products from Oregon. CLB can cause considerable damage to small-grain crops. Yield losses of up to 23 percent in winter wheat...
Las malas hierbas compiten con las plantas cultivadas para el agua, la luz, y los nutrientes. Algunas también abrigan insectos y enfermedades que pueden dañar las plantas. Si usted controla las malas hierbas, sus plantas tendrán más oportunidad de crecer bien y producir a su
potencial. Hay varios métodos de...
Las plantas que reciben la cantidad correcta de agua a lo mejor serán sanas y productivas. En Oregon, hay que regar las plantas durante el verano porque hay poca lluvia durante esa época. Al planear su huerto o jardín, considere cómo se suplirá el agua que sus plantas necesiten.

The influence of anthropogenic aerosols, in the form of ship exhaust effluent, on the microphysics and radiative properties of marine stratocumulus is studied using data gathered from the U.K. Met. Office C-130 and the University of Washington C-131A aircraft during the Monterey Area Ship Track (MAST) experiment in 1994. During...
