The lakes, rivers and coastal waters of Oregon have long provided the state's residents
and visitors with unique recreational boating environs and opportunities. However, this popular
activity represents more than a form of recreation: boating is an important component of the
Oregon economy. Each year, boaters spend millions of dollars...
Great Salt Lake (GSL), Utah, is surrounded by 191,884 hectares of wetlands. These wetlands provide critical habitat for hundreds of thousands of breeding, migrating and wintering waterfowl each year. As the human population around GSL increases, government officials have proposed to divert more water from the Jordan, Ogden, and Bear...
Properties of Mellin transforms are applied to the summation
of infinite series. A specific example of this application leads to the
establishment of certain properties of a generalization of Lerch's zeta
function.
Nine powerful methods of generating new tables of Mellin
transforms from existing tables of Mellin and other integral...
Oregon's forest product industry continues to be the nation's number one
producer of wood products. The forest products industry contributes significantly
to Oregon's economy. Changes in timber supply, land use policy, technology,
and product demand create significant impacts on the region. The activities of
the wood products industry translate into...
Watershed management is widely recognized as an important component of healthy ecosystems and its success depends on cultivating the good will, stewardship values, and participation of citizens. Because much of the streamside land in Oregon is in private ownership activities on public lands will not be enough to protect salmon...
Recent changes in public timber supplies in the Pacific Northwest have increased the
importance of the role private timber plays in the forest products industry and local
communities. Most economic models of timber supply, however, have emphasized
national or regional markets where data are adequate and statistical testing methodologies
relatively...
Like rural residents in other places, people in rural Oregon have expressed concern about the demographic shifts occurring in their communities. Principally they are concerned about youth leaving and not returning. This analysis uses recent Census Bureau data to describe, in detail, the demographic changes occurring in rural Oregon. Particular...
Forest recreation is one of the many non-commodity functions of forests that have
experienced a rapid growth in demand in the past few decades. Even faster growth in
demand for recreation is expected for several decades. However, such growing demand
for forest recreation is often not well perceived by owners...
The control of feral goats (Capra hircus) and relevant aspects of their biology were studied on Aldabra Atoll, Republic of Seychelles, from October 1993 - May 1994 and November 1994 - May 1995. A total of 832 goats were killed on Aldabra using both the Judas goat technique and traditional...
The practice of green infrastructure is synonymous with collaborative partnerships. Expertise from engineers, land care professionals, planners, and natural resource consultants are often required for successful project implementation. Traditionally, these professionals perform their responsibilities in their disciplinary “silos,” but this evolving area of sustainable development is creating a demand for...
The federal government is the largest single landowner in the 11 western states. The majority of federal lands is grazed by domestic livestock, a consumptive resource use. Communities have evolved dependent on traditional consumptive uses. Recently, non-traditional users today have contested public land management decisions and these users have become...

Declining population is a major concern for rural communities. In many places, out-migration has led to a loss of key services. This essay investigates the role of services, as well as labor markets, natural amenities, distance to urban areas, and community size, in determining net migration rates for small Oregon...
In the mountains of central and southern California, high elevation wilderness areas lack epiphytic lichens that can be used to inform us about atmospheric deposition in multiple ways. Epiphytic lichens are capable of accumulating elements proportionally to the local atmospheric concentration, establishing them as commonly used biomonitor of key elements....
The Symbolic Probabilistic Inference (SPI) algorithm was developed by Bruce D' Ambrosio for efficient calculation of prior probabilities in belief nets [2]. Although the complexity of the SPI algorithm compares favorably with other approaches to probabilistic inference [5], its actual running time is still prohibitively long even for moderately sized...
Riparian forests in the Idaho Panhandle, north of Whitebird, were surveyed for rare riparian lichen species. The region was stratified into nine geographic units and by stream size. Eighty-one plots were surveyed for lichen community, stand and river characteristics. Variables important to lichen community composition included regional differences, elevation, climatic...
The endangered Hawaiian common gallinule (Gallinula chloropus sandvicensis) is an endemic Hawaiian waterbird that occurs only on O‘ahu and Kaua‘i. Hanalei National Wildlife Refuge (NWR) supports the largest population of Hawaiian gallinule on either island and is also one of the highest producers of commercially grown taro in the state....
This paper describes Schemer, a hierarchical software architecture for Real Time problem solving. Real time applications must be able to react to critical events quickly, and be able to explore simultaneous solutions in response to, or, in anticipation of such events.
Schemer, which is a Blackboard-like architecture, addresses the aforementioned...
