Establishment and growth of natural and planted conifers ten years after overstory thinning and vegetation control in 50-year-old Douglas-fir stands

Creator:: Nabel, Mark R.
Abstract:: Forest managers of public lands in western Oregon and Washington have become increasingly interested in creating additional conifer cohorts in young, even-aged, second-growth Douglas-fir stands. The purpose of our research was to assess the establishment, survival, and growth of naturally-regenerated and underplanted conifers 10-13 years after overstory thinning and understory...

Overstory composition and stand structure shifts within inter-mixed ponderosa pine and lodgepole pine stands of the south-central Oregon pumice zone

Creator:: Shuffield, Chaylon D.
Abstract:: Ponderosa pine (Pinus ponderosa) and lodgepole pine (Pinus contorta var. murrayana) forests of south-central Oregon have been extensively researched over the last century. However, little information has been reported on overstory composition and stand structure shifts associated with fire exclusion within inter-mixed ponderosa pine and lodgepole pine stands of the...

Managing for landscape resilience in the frequent-fire forests of central Oregon

Creator:: Platt, Emily K.
Abstract:: Wildfire in dry, frequent-fire forests is a pressing issue for natural resource managers, communities and politicians in the western United States. Area affected by wildfire has climbed steadily over the last twenty years and is expected to increase in the future. Recognition of the importance of both social and biophysical...

LiDAR as Tool for Assessing Hazard Fuel Reduction Projects

Creator:: Olszewski, Julia H.
Abstract:: Land management practices in much of the western US that included wildland fire suppression have led to greater fuel loads than has been typical of historical fire regimes. In response to the increased wildland fire risk, “restoration” has emerged as a forest management goal. Restoration involves removal of uncharacteristic amounts...

Trade-offs between management for fire risk reduction and northern spotted owl habitat protection in the dry conifer forests of southern Oregon

Creator:: Comfort, Emily Julia, 1974-
Abstract:: There is a perceived trade-off between fire risk reduction and northern spotted owl habitat protection in dry-conifer forests in southwestern Oregon. Management options for balancing this trade-off need to be sought at the landscape level. Applied landscape ecology suggests three important features to consider are (1) patch size and configuration...

Diel Rest Structure Selection and Multiscale Analysis of Pacific Marten Resting Habitat in Lassen National Forest, California

Creator:: Tweedy, Patrick J.
Abstract:: Forests in the western United States have changed drastically over the past 150 years given a long history of utilization (harvest and grazing) and associated fire exclusion. These actions have altered the composition and structure of these forests as well as affected ecosystem function. Current policies for federal land management...

Bridging Ways of Knowing to Model the Dynamics of Fire as an Ecocultural Process on Frequent Fire Landscapes of the Pacific Northwest

Creator:: Greenler, Skye M.
Abstract:: Wildfire impacts have intensified in many ecosystems across the western United States due to the combined impact of fire exclusion, climate change, and land management practices. However, on many of these landscapes, fire is a fundamental ecological process that has shaped vegetation structural and compositional diversity, ecosystem function, landscape pattern,...

Red Tree Voles: Examining the Potential Factors Limiting Occupancy and Survival in Young Conifer Forests of the Central Oregon Coast Range

Creator:: Durham, William P.
Abstract:: Forested landscapes in the Pacific Northwest have changed drastically in the last Century with large-scale wildfires, and increased extent and frequency of commercial timber harvests. Thus, landscapes once dominated by older forest cover types became a matrix of younger forests with patches of older forests dispersed throughout. These younger forests...

Treatment options for controlling Brachypodium sylvaticum and impacts on native vegetation

Creator:: Fjeran, Taylor K.
Abstract:: Invasive vegetation control studies traditionally aim to control existing populations as well as limit future spread of the species. However, little additional attention has been dedicated to aiding native communities to recover and reestablish. One prominent example of a studied invasive is Brachypodium sylvaticum (Huds.) P. Beauv. (false brome), a...

Comparing Himalayan blackberry (Rubus armeniacus) management techniques in upland prairie communities of the W.L. Finley National Wildlife Refuge

Creator:: Ensley, Jona L.
Abstract:: Dedicated to the preservation and promotion of many of the nation’s most threatened and endangered species, the W.L. Finley National Wildlife Refuge is highly invested in the management of some of the last remaining upland prairies once prevalent throughout Oregon's Willamette Valley. More than a century of land fragmentation, fire...
