Four studies were conducted on late-summer diet quality and quantity of cattle (Bos taurus), mule deer (Odocoileus hemionus hemionus), and elk (Cervus elaphus) in response to prior grazing by cattle and elk on mixed-conifer rangelands and on related research techniques. In our first study we assessed a photographic technique to...
An experiment was conducted to evaluate the influence of forest fuels reduction on the diet quality, botanical composition, relative preference, and foraging efficiency of beef cattle grazing at different stocking rates. A split plot factorial design was used, with the whole plots (3 ha) being fuel reduced or no treatment...

The Warm Springs Reservation is located in central Oregon. Livestock production consists of beef (commercial with an Angus, Horned Hereford base) and roping (Corriente and Longhorn) cattle and horses that forage most of the year on the open range within reservation boundaries. Forage consists of annual and perennial grasses and...
CTSPAC is a mathematical model for coupled transport of water, solutes, and thermal
energy in the soil-plant-atmosphere continuum. The mathematical structure consists
of coupling a model for transport through soil (soil submodel) to one for xylem and phloem
transport (plant submodel). The modeling approach is based on discrete space conceptualization...

A comprehensive approach to nutrient management will help you ensure availability of optimum levels of nutrients for tree growth. Components of a comprehensive nutrient management strategy include:
• Soil analysis before planting (useful in predicting the need for potassium, magnesium, or lime applications)
• Observations of annual shoot growth, leaf...

Several types of caneberries are produced commercially in Oregon, including summer-bearing and primo cane fruiting red raspberries, black raspberries (blackcaps), and blackberries. This publication addresses nutrient assessment
and application for caneberries produced in western Oregon.
In this area, caneberries typically are planted on Aloha, Jory, Newburg, Willamette, Woodburn, or Saum...
