NITROGEN STATUS IN OREGON COAST RANGE FOREST COMMUNITIES INTRODUCTION Sensitive stewardship of forest resources requires an under-' standing of ecosystem characteristics and processes. In the Pacific Northwest, stratification of the forest into communities has been a useful approach to analyzing important characteristics and processes.

Management practices that conserve or add nitrogen are more critical in salal community types. Abstract. Variations in plant community composition across the landscape can influence nutrient retention and loss at the watershed scale.

A striking example of plant species importance is the influence of N 2-fixing red alder (Alnus rubra) on nutrient cycling in the forests of the Pacific understand the influence of red alder on watershed nutrient export, we studied the chemistry Cited by:   Forest productivity, like that of most terrestrial ecosystems, is generally nitrogen limited (Myrold, ), and N is recognized as the most limiting element for forest growth in the Pacific Northwest (Johnson et al., ).Cited by: Forest and Stream Management in the Oregon Coast Range is the capstone of this effort and the synthesis of years of collaborative research.

The book's ten chapters, written by scientists from leading research institutions, offer a thorough grounding in Coast Range geophysical processes, plant community ecology and dynamics, fisheries, wildlife.

The amount of old-growth forest in the Oregon Coast Range has changed dramatically. Under the historical fire regime, Teensma and others () estimate old-growth covered 40 percent and 46 percent of our study area in andrespectively.

In contrast, the FEMAT () estimate of current old-growth is only 2 percent of the Coast Range. Two Oregon tree plantations, with differing soil properties were selected for this were located in the Cascade Head Experimental Forest (Grotta et al., ) and the H.J.

Andrews Experimental Forest (Radosevich et al., ).Cascade Head is located approximately km from the Pacific Ocean in the Oregon coastal range at an elevation of m.

A striking example of plant species influence is the role of N2-fixing red alder (Alnus rubra) in the biogeochemistry of Pacific Northwest forests. To understand the connection between the distribution of red alder and watershed-scale nutrient losses, we studied the.

Background sources of nitrogen (N) provide a challenge for setting stream nutrient criteria in the Pacific Northwest US. Red alder (Alnus rubra), an early successional nitrogen fixing tree, and sea salt inputs can strongly influence stream N concentrations observed in individual studies in western Oregon and Washington.

We used data from various monitoring and GIS efforts (e.g., US EPA, Oregon. Oregon’s forests are home to an array of wildlife. This interactive guide provides a snapshot of the variety of forest-dwelling animals found in the state.

Protecting forestland from development is a great way to minimize habitat loss for species that rely on forests. Forest landowners can also use forest management techniques to maintain, enhance and even create habitat for birds, mammals.

On average, the Clatsop State Forest plantstotrees a year. The planting usually is 60 percent Douglas fir, 30 percent hemlock, and a 10 percent mix of noble fir, grand fir, cedar. Oregon is home to some of the world's most productive forests. From the dense Douglas-fir forests of the Willamette Valley and Coast Range to the high desert Ponderosa Pine stands in the Cascades and Blue Mountains, Oregon offers a wealth of forest resources.

In fact, forests cover over The Panther Creek watershed, in the northeastern Oregon Coast Range, has been intensively studied and instrumented, and serves as a case study for the broader Coast Range. In the Panther Creek watershed, we assessed seven climate projections to capture a large range of variability in potential future temperature and precipitation.

We explored. This proposal is divided into 3 focci:1) Forest Nutrition Management - We will examine forest productivity respose to novel fertilizer applications in the Oregon Coast Range and Cascade Foothils2) The Role of Forest Nutrition in Foliar Diseases - We will examine the incidence and severity of Swiss Needle Cast in relation to soil and climate.

Southern Coastal Oregon Abstract The coastal forests of Oregon are among the most biologically productive regions in the world. This high level of forest productivity enabled a large timber industry to grow in the region, and supply the area with its economic and cultural base.

Biogeochemical theory emphasizes nitrogen (N) limitation and the many factors that can restrict N accumulation in temperate forests, yet lacks a working model of conditions that can promote naturally high N accumulation. We used a dynamic simulation model of ecosystem N and δ15N to evaluate which combination of N input and loss pathways could produce a range of high ecosystem N.

We investigated how riparian-forest community composition, understory density, and lateral slope shaped vertical and lateral litter inputs to 16 streams in the Oregon Coast Range.

Winter temperatures and spring precipitation have increased by 02–04°C and 07–15 cm, respectively, per decade since in the Oregon Coast Range, suggesting that regional climate changes may be influencing the distribution and severity of the disease in the Oregon Coast Range (Stone et al., ).

We used naturally occurring stable isotopes of N to compare N dynamics in near-stream and upslope environments along riparian catenas in N-fixing red alder (Alnus rubra) and Douglas-fir (Pseudotsuga menziesii) forests in the Coast Range of western Oregon.

Range Coast redwood is the rarest forest type in Oregon. It is the northernmost extension of the much larger redwood forest of northern California, reaching only about 10 miles across the border into southern Oregon. In general, Oregon's redwoods are found on mountainous slopes, rather than in river bottoms like their California counterparts.

The Forest Engineering & Research Management Department comprises a unique group of specialists in forest management, engineering, biometrics, hydrology, forest health, fire behavior and management, and silviculture working to support decisions for sustainable forests. Our teaching and research emphasize all aspects of active forest management and restoration from regeneration through harvest.

This is especially true for lowland forest ecosystems of the tropics which can be taxonomically and functionally diverse and rich in bioavailable nitrogen (N).

In many tropical regions, however, diverse forests occur side-by-side with monodominant forest (one species >60% of canopy); the long-term biogeochemical consequences of tree. ‐ Visiting Associate Professor, Department of Forest Science, OSU.
