The listing of many Pacific Northwest anadromous fish stocks as threatened or endangered has heightened the need to protect or enhance the health of entire river systems. Salmon, steelhead, and other anadromous fish swim from the ocean to the headwaters of their home river, where they spawn. Their young hatch...
During clearcut logging, complete removal of the forest canopy and the shade it provides
to small streams can cause large increases in water temperature. Such increases in temperature can be prevented if buffer strips of vegetation are left along the stream to provide shade. The purposes of this paper are...
Whether you have 1 or 500 acres, it's important to have natural vegetation growing along the streams on your property. It's good for wildlife, stream health and property values.
Recent concerns about surface water quality near agricultural production areas have stimulated interest in “best management practices” to reduce the risk of off-site sediment, pesticide, and nutrient movement. Vegetative filter
strips can be one component of an integrated management system to reduce these risks.
The Dwight L. Phipps State Forest Nursery at Elkton annually supplies 22 million 2-0
Douglas-fir seedlings to Oregon land managers. Some managers report excellent success in
planting, but others report failures, particularly when planting late in the season. In some
instances poor survival seemed to be related to storage.
Physiological...
This manual describes the rules for reforesting after harvest of small woodlands, gives guidance for the decisions the landowner must make, and gives step-by-step instructions for planting and taking care of seedlings.
1. La costa: La época de los cultivos es larga y fresca, de 190 a 250 días.
2. Los valles occidentales (entre Portland y Roseburg): La época de los cultivos es de 150 a 250 días; días calientes, noches frescas; la duración de la temporada puede variar de un año...
Orchardgrass and tall fescue seed crops are commonly springplanted
in Oregon, but do not produce a marketable crop during the first
growing season. Establishing orchardgrass and tall fescue with cereal
companion crops would provide income during the seeding year and could
increase seed production profits. This study was conducted to...
Riparian vegetation is an essential component for the maintenance and/or repair of channel stability and function. Sedges within low-gradient riparian systems provide the structure necessary for sediment trapping leading to channel narrowing through bank building processes. Planting success in riparian restoration projects has often failed due to inappropriate species selection,...
