Welcome to the premier issue of the Cascade Center News. We created this bulletin in response to suggestions that we share information more widely and on a regular basis to Willamette National Forest employees and other interested agency personnel. We thought we'd start with 2 newsletters a year, gauge interest, and adjust accordingly. Please send any reactions and suggestions about this communication effort to: P.Druliner:RO6F18D01A. THANKS. ANDREWS WEB PAGE The Andrews Forest is one of 18 national research sites in the National Science Foundation's Long-term Ecological Research Program (LTER). The LTER Network is a collaborative effort among over 600 LTER scientists and students which extends the opportunities and capabilities of the individual sites to promote synthesis and comparative research across sites and across ecosystems. As part of the NSF's effort to make LTER information (including data bases) available online, the Andrews Forest has developed it's own WEB site. The Andrews WEB site includes: information on the Cascade Center, summaries of current research; current events (including photos and analysis of the flood); information on spatial, plot, and model data sets; and a pictorial tour of the Andrews Forest, facilities, and personnel. http://www.fsl.orst.edu/lter FLOOD ASSESSMENT Flood Report: Ted Dyrness, retired PNW Station soil and vegetation scientist, is preparing a short paper about the 1996 flood and the Andrews Forest. It will include a brief overview of the Andrew's climate, streamflow, ecosystem disturbance, and research opportunities from the flood event. Data from climate stations and streamflow gauges are summarized and given initial interpretation. Comparison with the December 1964 storm is made in various respects. A draft is available via the Andrews WEB page or from Tami Lowry (541) 750-7488. Flood Pulse: A science field pulse in the Andrews and vicinity occurred June 24-28. Approximately 60 participants from OSU, PNW Station, and the Willamette National Forest, spent the week sampling and interpreting flood effects on geomorphology, riparian vegetation, fauna in Lookout Creek and neighboring areas. Information will be shared in a variety of future publications and forums. Landslide Inventory: will begin this summer in Blue River watershed to determine initiation mechanisms and the role of changing management practices on number and intensity of landslide events resulting from this year's flood. Information will be compared to data collected during previous inventories. Andrews Travel Access: Post-flood access to the Andrews was substantially reestablished in less than 3 months. Many road fixes are temporary with permanent road fixes to follow beginning this summer. Please use extra caution when driving within the Andrews and elsewhere within the forest. NORTHWEST CENTER FOR SUSTAINABLE RESOURCES (NCSR) The Cascade Center is one of over 128 northwest partners in the Northwest Center for Sustainable Resources -- a National Science Foundation supported program established to develop natural resources technology programs for community colleges that incorporate higher levels of math and science. NCSR programs will use an ecosystems-based approach that emphasizes sustainable methods of resource use. The Andrews Forest will have a major role, providing a direct link between OSU's forest sciences research and education programs and NCSR. One feature of the NCSR program is faculty development. A training course is planned at the Andrews for community college instructors from August 18-23. The workshop has been advertised nation-wide and enrollment will be limited to 15 participants.

PROJECT SPOTLITE: RETROSPECTIVE STUDIES ON THE WILLAMETTE NATIONAL FOREST The Retrospective Study is a combined effort of many researchers from Oregon State University and the USFS PNW Research Station working in cooperation with the Willamette National Forest. The study includes numerous related efforts examining effects of green tree retention both in naturally regenerated stands and in recent retention harvest units. Overall coordinators for the project are Steve Acker at Oregon State University, Tom Spies, USFS PNW Research Station in Corvallis, and Jim Mayo at Blue River Ranger District. The studies are summarized in the Cascade Center's Communique No. 2: Residual Trees as Biological Legacies (see Recent Publications). They include: Retrospective studies on the effects of green tree retention on conifer production, forest floor bryophyte and understory vascular plant diversity, and canopy lichen communities; Survival and function of ectomycorrhizal soil mats in green tree retention harvest units; Diversity of mycorrhizal fungi in green tree retention harvest units; and Arthropod diversity and biomass in clearcuts, green tree retention stands, and mature forest. With respect to conifer production, the presence of residual trees at basal areas roughly comparable to amounts currently prescribed for Federal forests in western Oregon was associated with significant decreases in basal area, volume, and mean annual increment of the younger cohort of trees. For understory herbs and shrubs, responses to abundance of residual trees were mediated through effects of residual trees on the younger cohort of trees. Herb and shrub cover and species richness tended to increase with increasing Douglas-fir in the younger cohort, which was associated with fewer residual trees, drier sites, and lower density of the young cohort. Biomass of alectoroid lichens (genera Alectoria, Bryoria, and Usnea, important food sources for small mammals and ungulates) and nitrogen-fixing cyanolichens was greater in plots with residual trees. The investigators emphasized that retrospective studies have both strengths (they provide information long before manipulative experiments could be completed) and limitations (especially lack of control over or detailed information on the disturbances that initiated the stands). The studies that focused on recent green tree retention cuts also suggested that effects of residual trees on biodiversity differs for different functional groups of species. The frequency of mycorrhizal mats was greater near living host trees in control stands, with evidence from green tree retention cuts that mats may persist for at least 2 years after their host trees have been cut. Ectomycorrhizal diversity on Douglas-fir seedlings planted near or far from green trees, however, showed no clear patterns of influence by the retained tree. Different functional groups of arthropods had different patterns of abundance across a range of stand structures, including recent green tree retention cuts, clear cuts, and mature forests. Biomass of flying arthropods was greatest in green tree retention cuts (favoring avian predators). In contrast, biomass of ground-dwelling macroarthropods was highest in clearcuts; biomass of soil microarthropods peaked in mature forests. More comprehensive reports of the above studies are included in the Final Report: Retrospective studies of the effects of green tree retention on conifer production and biodiversity on the Willamette National Forest (see Recent Publications). *** Summer Issue Quote *** "When we try to pick out anything by itself, we find it hitched to everything else in the universe."
