Species, diversity, and density affect tree seedling mortality from Armillaria root rot

Creator:: Gerlach, J. P., Reich, P. B., Puettmann, Klaus J., and Baker, T.
Abstract:: Mortality from Armillaria root rot is a major concern of forest management. Field experiments were conducted in Minnesota to evaluate interspecific differential susceptibility and to assess whether density or species composition, specifically the proportion of conifers in a plot, influences seedling mortality from Armillaria spp. Seedlings of 10 tree species...

Canopy type, forest floor, predation, and competition influence conifer seedling emergence and early survival in two Minnesota conifer-deciduous forests

Creator:: Cornett, Meredith W., Puettmann, Klaus J., and Reich, Peter B.
Abstract:: There is concern that the conifer component of mixed conifer-deciduous forests in the Great Lakes region is on the decline, possibly the result of insufficient conifer regeneration. Limitations on conifer regeneration that occur during the first 18 months of seedling emergence and establishment were examined for Abies balsamea (L.) Mill....

Land-use in the Willamette Valley from 2004-2017

Creator:: Strimbu, Bogdan M., Mueller-Warrant, George, and Trippe, Kristin
Abstract:: The Willamette Valley, bounded on the west by the Coast Range and on the east by the Cascade Mountains, is the largest river valley completely confined to Oregon. The fertile valley soils combined with a temperate, marine climate create ideal agronomic conditions for seed production. Historically, seed cropping systems in...

Modeling the incidence and severity of hemlock dwarf mistletoe in 110-year-old wind-disturbed forests in Southeast Alaska

Creator:: Trummer, L. M., Hennon, P. E., Hansen, E. M., and Muir, P. S.
Abstract:: A model was developed to predict the severity of dwarf mistletoe (Arceuthobium tsugense (Rosendahl) G.N. Jones) in western hemlock trees (Tsuga heterophylla (Raf.) Sarg.) that developed within forests of Southeast Alaska that experienced near-catastrophic windthrow in the late 1800s. The model suggests that the degree of dwarf mistletoe severity on...

Contributions of ectomycorrhizal fungal mats to forest soil respiration

Creator:: Phillips, C. L., Kluber, L. A., Martin, J. P., Caldwell, B. A., and Bond, B. J.
Abstract:: Distinct aggregations of fungal hyphae and rhizomorphs, or "mats", formed by some genera of ectomycorrhizal (EcM) fungi are common features of soils in coniferous forests of the Pacific Northwest. We measured in situ respiration rates of Piloderma mats and neighboring non-mat soils in an old-growth Douglas-fir forest in western Oregon...

Leaf litter chemistry controls on decomposition of Pacific Northwest trees and woody shrubs

Creator:: Valachovic, Y. S., Caldwell, B. A., Cromack Jr., K., and Griffiths, Robert P.
Abstract:: The effects of initial leaf litter chemistry on first-year decomposition rates were studied for 16 common Pacific Northwest conifers, hardwoods, and shrubs at the H.J. Andrews Experimental Forest in western Oregon. Leaf litters were analyzed for C, N, P, K, Ca, Mg, proximate organic fractions (nonpolar, polar, acid-hydrolyzable extractives, acid-hydrolyzable...

Size and survival of 2-0 Douglas-fir seedlings

Creator:: Zaerr, Joe B., Lavender, Denis P., and Oregon State University. Forest Research Laboratory
Abstract:: Results reported here are from a large study designed to evaluate the effects of certain nursery procedures on subsequent survival of Douglas-fir seedlings. The effects of storage conditions and lifting dates were reported elsewhere (9). The determination of the optimum size of seedling for planting on different sites has been...
