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.
Today, turfgrass is the single largest irrigated crop in the United States and covers three times the land area of any other cultivated crop. An estimated 40.5 million acres of grasses are planted in residential, commercial and...
Fire severity is a measure of the effects of fire on the environment—both in damage to vegetation and impacts on the soil. Fire severity is driven by weather conditions, the topography of the landscape, and the fuels that are present. Of these, weather is the overriding factor.
This publication outlines the role of forest organic debris in inland Northwest forests. Recommends how to maintain forest soil productivity and improve wildlife habitat while reducing wildfire and insect-pest hazards. Tells how to ...
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.
Plant growth and geographic distribution are greatly affected by the environment. Either directly or indirectly, most plant problems are caused by environmental stress. Environmental factors that affect plant growth include light, temperature, water, humidity, and nutrition.
A guide for how to collect and where to get a sample analyzed for plant diseases.
Blueberries grow well in the Pacific Northwest. To get the most out of your bushes, it helps to understand the form and function of each part of the plant.
Plant hormones and growth regulators are chemicals that affect flowering, aging, root growth, distortion and killing of organs, prevention or promotion of stem elongation, color enhancement of fruit, prevention of leafing and/or leaf fall, and many other conditions.
