Interference dynamics in mixed red alder/Douglas-fir forests

Creator:: D'Amato, Anthony W.
Abstract:: This study characterized the nature and dynamics of interference in mixed red alder (Alnus rubra Bong.)/Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) stands in the Pacific Northwest, USA. Long-term spatial and tree measurements from the Cascade Head (CH) and H.J. Andrews (HJA) Experimental Forests in western Oregon and Delezene Creek (DC), Washington...

The size-density relationship in pure and mixed red alder/Douglas-fir stands and its use in the development of a growth model

Creator:: Puettmann, Klaus J.
Abstract:: The increased interest in red alder (Alnus rubra Bong.) management instigated research in growth and yield and stand development of red alder in pure and mixed red alder/Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) stands. This study had the goa1s of evaluating the accuracy of the currently existing growth and yield tools...

Effects of overstory and understory competition and simulated herbivory on growth and survival of white pine seedlings

Creator:: Saunders, Mike R. and Puettmann, Klaus J.
Abstract:: The interactive impact of overstory canopy closure, understory brush control, and simulated white-tailed deer (Odocoileus virginianus Zimmermann) herbivory (i.e., clipping) on growth and survival of underplanted white pine (Pinus strobus L.) seedlings was examined. Clipping was conducted in April 1996 and 1997 at three intensities (control, 0% previous year’s growth...

Canopy gaps affect the shape of Douglas-fir crowns in the western Cascades, Oregon

Creator:: Seidel, Dominik, Ruzicka, Kenneth J., and Puettmann, Klaus
Abstract:: Silvicultural regimes that aim at an increased stand structural diversity typically promote small-scale heterogeneity in horizontal and vertical structures, e.g. through the creation of gaps. We used terrestrial laser scanning (TLS) to investigate impacts of altered growing conditions on trees adjacent to artificial gaps as compared to responses of trees...

Management of Riparian Buffers: Upslope Thinning with Downslope Impacts

Creator:: Ruzicka, Kenneth J., Jr., Puettmann, Klaus J., and Olson, Deanna H.
Abstract:: We examined the potential of using upslope density management to influence growth and drought tolerance of trees in untreated downslope riparian forests. Increment cores from Douglas-fir trees in three mature stands in western Oregon, USA, were collected and measured. Trees responded to an apparent edge effect up to 15 m...

Light availability and soil compaction influence the growth of underplanted following partial shelterwood harvest and soil scarification

Creator:: Soto, Daniel P., Donoso, Pablo J., Salas, Christian, and Puettmann, Klaus J.
Abstract:: We evaluated effects of top-soil scarification by heavy machinery on growth of two valuable and shade-intolerant tree species - Nothofagus dombeyi (evergreen and considered very plastic to different soil fertility levels) and Nothofagus alpina (deciduous and considered sensitive to soil fertility) - seedlings underplanted in Nothofagus old-growth forests subjected to...

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...

BurtonEffectsRiparianBufferSupplement.pdf

Creator:: Burton, Julia I., Olson, Deanna H., and Puettmann, Klaus J.
Abstract:: Forested riparian buffer zones are used in conjunction with upland forest management, in part, to provide for the recruitment for large wood to streams. Small headwater streams account for the majority of stream networks in many forested regions. Yet, our understanding of how riparian buffer width influences wood dynamics in...

Bird-vegetation associations in thinned and unthinned young Douglas-fir forests 10 years after thinning

Creator:: Yegorova, Svetlana, Betts, Matthew G., Hagar, Joan, and Puettmann, Klaus J.
Abstract:: Quantitative associations between animals and vegetation have long been used as a basis for conservation and management, as well as in formulating predictions about the influence of resource management and climate change on populations. A fundamental assumption embedded in the use of such correlations is that they remain relatively consistent...

Multiscale Controls on Natural Regeneration Dynamics after Partial Overstory Removal in Douglas-Fir Forests in Western Oregon, USA

Creator:: Dodson, Erich K., Burton, Julia I., and Puettmann, Klaus J.
Abstract:: We examined natural regeneration following operational-scale variable density retention treatments in 40-60 year old Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) forests at seven sites for a decade following treatment. Treatments included residual overstory densities of 300, 200, and 100 trees/ha, with leave islands and gaps of three sizes (0.1, 0.2, and...
