Influence of Bravo fungicide applications on wood density and moisture content of Swiss needle cast affected Douglas-fir trees

Creator:: Johnson, G. R., Gartner, Barbara L., Maguire, Doug, and Kanaskied, Alan
Abstract:: Wood density, moisture content, tracheid width and cell wall size were examined in trees from plots that were sprayed for 5 years with chlorothalonil (Bravo®) fungicide to reduce the impact of Swiss needle cast (SNC) and from trees in adjacent unsprayed plots. The unsprayed (more heavily diseased) trees had significantly...

Dataset: Experimental evaluation of herbicide use on biodiversity, ecosystem services and timber production tradeoffs in forest plantations.

Creator:: Thomas D. Stokely
Abstract:: This dataset includes species richness of native plants, pollinators and birds as well as 13 proxies for ecosystem services representing timber production, culturally-valued plants and animals, and regulating services tied to forest productivity. The data were collected from an experiment conducted in the Oregon Coast Range USA that sought to...

Conifer response to three silvicultural treatments in the Oregon Coast Range foothills

Creator:: Walter, Scott T. and Maguire, Chris C.
Abstract:: This study assessed growth, condition, and mortality of residual trees one decade after harvest across three silvicultural treatments in thirty 85- to 125-year-old Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) stands in the Oregon Coast Range foothills. Group-selection cuts had 33% of the entire stand volume extracted as patches approximately 0.2–0.8 ha...

Crown structure and growth efficiency of red spruce in uneven-aged, mixed-species stands in Maine

Creator:: Maguire, Douglas A., Brissette, John C., and Gu, Lianhong
Abstract:: Several hypotheses about the relationships among individual tree growth, tree leaf area, and relative tree size or position were tested with red spruce (Picea rubens Sarg.) growing in uneven-aged, mixed-species forests of south-central Maine, U.S.A. Based on data from 65 sample trees, predictive models were developed to (i) estimate the...

Thinning ponderosa pine (Pinus ponderosa) stands reduces mortality while maintaining stand productivity

Creator:: Zhang, Jianwei, Ritchie, Martin W., Maguire, Douglas A., and Oliver, William W.
Abstract:: We analyzed 45 years of data collected from three ponderosa pine (Pinus ponderosa Douglas ex P. Lawson & C. Lawson) levels-of-growing-stock installations in Oregon (OR) and northern California (CA), USA, to determine the effect of stand density regimes on stand productivity and mortality. We found that periodic annual increment (PAI)...

Three-year growth response of young Douglas-fir to nitrogen, calcium, phosphorus, and blended fertilizers in Oregon and Washington

Creator:: Mainwaring, Douglas B., Maguire, Douglas A., and Perakis, Steven S.
Abstract:: Studies of nutrient limitation in Douglas-fir forests of the Pacific Northwest focus predominantly on nitrogen, yet many stands demonstrate negligible or even negative growth response to nitrogen fertilization. To understand what nutrients other than nitrogen may limit forest productivity in this region, we tested six fertilizer treatments for their ability...

College of Forestry Integrated Research Project : ecological and socioeconomic responses to alternative silvicultural treatments

Creator:: Maguire, Chris C., Chambers, Carol L., and Oregon State University. Forest Research Laboratory
Abstract:: The College of Forestry Integrated Research Project (CFIRP) is an on-going experiment in the eastern Coast Range foothills of western Oregon. Started in 1989, a team of scientists, resource managers, and students at Oregon State University designed and implemented silvicultural alternatives to clearcutting. These silvicultural practices aimed to create and...

Impact of the foliar pathogen Swiss needle cast on wood quality of Douglas-fir

Creator:: Johnson, G. R., Grotta, Amy T., Gartner, Barbara L., and Downes, Geoff
Abstract:: Many stands of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) near coastal areas of Oregon and Washington are heavily infected with the foliar pathogen causing Swiss needle cast (SNC) disease, and yet there is very little research on the resulting wood quality.

Sampling Strategies for Efficient Estimation of Tree Foliage Biomass

Creator:: Temesgen, Hailemariam, Monleon, Vicente, Weiskittel, Aaron, and Wilson, Duncan
Abstract:: Conifer crowns can be highly variable both within and between trees, particularly with respect to foliage biomass and leaf area. A variety of sampling schemes have been used to estimate biomass and leaf area at the individual tree and stand scales. Rarely has the effectiveness of these sampling schemes been...

Relationships between Swiss needle cast and ectomycorrhizal fungus diversity

Creator:: Luoma, Daniel L. and Eberhart, Joyce L.
Abstract:: Swiss needle cast (SNC) is a disease specific to Douglas-fir (Pseudotsuga menziesii) caused by the ascomycete Phaeocryptopus gaeumannii. Here we examine characteristics of the EM fungus community that are potentially useful in predictive models that would monitor forest health. We found that mean EM density (number of colonized root tips/soil...
