Scientists have developed a new approach to modeling potentially drought-prone soils in Pacific Northwest forests, which could aid natural resource managers to prepare forested landscapes for a changing climate.
Most “sick tree” problems can be traced back to underlying stresses that have reduced the tree's vigor, making it more vulnerable to diseases or insect pests.
At times we see many of our cool-season perennial and annual forages looking stressed and growing very slow as they struggle with heat and no rain. The hot, dry conditions we sometimes experience in western Oregon have many pasture and hayground managers thinking about forages that can be productive under these circumstances. Fortunately, there are some strategies to consider ...
Browning or dieback is usually caused by weather-related stress, sometimes in combination with pests and diseases.
Drought, an environmental stress with periods of limited or no water during the growing season, reduces forage production for grazing and haymaking. Prolonged drought forces livestock and hay producers to better manage their fields to maximize recovery after the drought ends. Forage produced during a drought may be stressed enough that livestock risk death by simply eating it. The...
Trees all over Oregon are displaying signs of poor health. People are quick to blame insects, but insects are rarely the underlying cause of the problem. Drought and other stressors can make trees vulnerable to pests and disease.
Poisonous plants are a major cause of economic loss to the livestock industry. Two poisonous plants common to Oregon are poison hemlock and Western water hemlock. Ingestion of either by humans or livestock typically results in death.
Poison hemlock is one of the most poisonous of plants. Silage making has been used to reduce the concentrations of toxins in a variety of crops. Poison hemlock alkaloids are found in different concentrations depending on several factors that make it virtually impossible to predict how dangerous the plant is at any given time.
