Wall-to-Wall Forest Mapping in Southeast and Southcentral Alaska: A New Application of the Gradient Nearest Neighbor Approach

Creator:: Irvine, Daniel R.
Abstract:: Boreal and temperate biomes host nearly half of the earth’s forested ecosystems. The temperate rainforests of the Pacific coast of North America constitute nearly half of all temperate rainforests on earth. Along the northern extent of this region, the perhumid and sub-polar rainforests of southeast and southcentral Alaska are among...

Exploring Alternative Approaches for Native Plant Production and Ecological Restoration in the Pacific Northwest

Creator:: Placido, Wilman M.
Abstract:: Global recognition of the need for ecosystem restoration and revegetation following natural and anthropogenic disturbances has been growing in recent years. Successful programs often depend on the use of nursery-grown seedlings and appropriate mitigation of limiting factors on outplanting sites. Nursery production of high-quality native plants for restoration can be...

Effects of soil amendment treatments on survival and growth of four fast-growing tree species on degraded mine areas in the Peruvian Amazon

Creator:: Llancari Valenzuela, Yury Milagros
Abstract:: This paper aims to increase the knowledge on establishment practices for four fast-growing species (Guazuma crinita Mart., Eucalyptus grandis x E. urophylla, Bixa orellana L., Psidium guajava L.) in areas degraded by gold mining in the Peruvian Amazon. The study was carried out in Madre de Dios region, located in...

Assisted Migration in the Colorado Subalpine Forest

Creator:: Najim, Tara
Abstract:: This capstone study reports on global warming-induced changes to the Colorado subalpine zone climate and disturbance regimes. It assesses the impacts of these changes upon the dominant subalpine tree species and summarizes future species distribution modeling for these and other nearby species potentially suitable for the future subalpine zone in...

Recovering Lost Ground : Effects of Soil Burn Intensity on Nutrients and Ectomycorrhiza Communities of Ponderosa Pine Seedlings

Creator:: Cowan, Ariel D.
Abstract:: Fuel accumulation and climate shifts are predicted to increase the frequency of high-severity fires in ponderosa pine (Pinus ponderosa Dougl. ex Laws) forests of central Oregon. The combustion of fuels containing large downed wood can result in intense soil heating, alteration of soil properties, and mortality of microbes. Previous studies...

Planning for the Future Forest on the Northern Shawangunk Ridge: Climate-Adaptive Disturbance Preparedness and Response Recommendations

Creator:: Randazzo, Andrew
Abstract:: Mohonk Preserve intends to manage their forestland more actively with the mission of promoting forest health, climate-adaptation, and overall ecosystem health for the benefit of their community and recreational users. Climate-adaptive management recommendations (recommendations that address climate change vulnerabilities —by promoting either resistance, resilience, or transition— while helping to meet...

Comparing Ectomycorrhizal Communities of Understory Giant Chinquapin (Chrysolepis chrysophylla) and Overstory Pinaceae Trees in a Mixed Conifer Forest in Central Oregon

Creator:: Longway, Lucas J.
Abstract:: Giant chinquapin (Chrysolepis chrysophylla) is an evergreen hardwood often found as a shrubby understory component of coniferous forests in the Pacific Northwest United States. Due to its ability to sprout quickly after disturbances such as fire and logging it is often viewed as a pest by forest managers. Like its...

Douglas-fir Seedlings in the Pacific Northwest: The Genetics of Drought Adaptation

Creator:: Celer, Erda
Abstract:: Douglas-fir (Pseudotsuga menziesii) is a widely distributed, ecologically important, and commercially valuable tree species in North America. However, climate change is expected to adversely impact Douglas-fir trees, and assisted migration may become necessary to lessen the effects of climate change. Because drought stress is one of the projected effects of...

An Analysis of Nutrient Depletion in Douglas-fir Forests of the Oregon Coast Range

Creator:: Siah, Kaveh G.
Abstract:: Nutrient limitation constrains tree growth in many managed forests. Nitrogen (N) is the most common limiting nutrient, but high N supply can shift limitation to other nutrients, particularly phosphorus (P) and the base cations calcium (Ca), magnesium (Mg), and potassium (K). As different soil minerals have different capacities to supply...
