Graduate Certificate Program in Sustainable Natural Resource Management [Oregon State University]
Presented at the Natural Resources Distance Learning Consortium Symposium.This symposium consists of presentations and discussions looking to the future of natural resources distance learning concepts. Key issues that will be discussed include: faculty development, technology roles - from remote imaging transmitted to the classroom to iPod lecture series and field assignments, credit transfer among Consortium members, faculty recruitment, funding course development, and innovation in course delivery. The epicenter of discussion is meeting the needs of students currently employed who cannot afford time or cost to relocate at a university campus to complete graduate courses or degree programs, meeting needs of natural resource agencies (federal, state and local), and future roles of professional societies (professional licensing and certifications). Among the futures issues will be presentations on meeting the needs of the agencies with hybrid (on-line and in the field) courses, Blended Learning (using multiple media technologies to teach a single lesson), and the new role of the employee’s career development system, e.g. DoILearn (Department of the Interior) and AgLearn (Department of Agriculture). Presenters will introduce issues the Consortium faces such as, developing and maintaining active course listings, common structure to on-line course listings, “what our students want, and what our agency clients want!”, “academic credits from accredited institutions”; understanding Learning and Content Management Systems with focus on knowledge, skills and abilities, and linkages between extension faculty and faculty in graduate programs. Presenters also will focus on the contemporary issues of faculty recruitment and development, linkages between the Land Grant/McIntire-Stennis natural resource colleges to the State Colleges, and private sector venders contracting to Federal and State agencies. The NRDL Consortium Policies and Procedures (draft) will be introduced.

Effects of contrasting light and soil moisture availability on the growth and biomass allocation of Douglas-fir and red alder
We examined growth and biomass allocation of individual Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) and red alder (Alnus rubra Bong.) seedlings grown for 3 years under contrasting combinations of light and water. Alder growth was always greater than Douglas-fir. Full sunlight and soil moisture at field capacity caused large differences in size between the two species. With limited light and water, differences were smaller. Under full light and limited water, Douglas-fir allocated a high portion of its biomass to roots, whereas red alder allocated a high percentage to aboveground biomass components. Under light and water resource-limiting situations, red alder allocated more
mass to stem, whereas Douglas-fir allocated more to roots. Red alder growth responded negatively to water limitation, whereas Douglas-fir did not. Red alder exhibited greater foliage plasticity to light. Species differences in size and allocation
in response to resource availability may determine pathways by which Douglas-fir and red alder interact in a mixed community. Our findings support the hypothesis that the potential of species to use growth-limiting resources is an indicator of competitive ability. We suggest that red alder and Douglas-fir can co-exist under conditions of full light and limiting soil moisture availability. Furthermore, when contrasted with red alder, Douglas-fir’s relatively greater tolerances to low light allow it to better persist in the understory. Red alder’s rapid early growth and competitive ability will be superior under full light and nonlimiting soil moisture conditions
