Aspen Bibliography
The quality of polluted soil can much be improved and the environmental risks reduced by use of phytoremediation. Harmful hydrocarbon compounds can be degraded through the activity of plant and its associated microbes. We previously showed that PAHs increase aromatic ring-cleavage gene diversity in rhizosphere of birch (Sipilä et al. 2008, Yrjälä et al. 2010a) and the rhizosphere of aspen harbors Burkholderia bacteria able to degrade aromatics (Yrjälä et al. 2010b). The results are promising for successful remediation of polluted soils with woody plants. The aim of our studies is to elucidate the response of the plant and the associated …

Spruces are common trees in cultivated landscapes in Utah. They have varied shapes, attractive foliage color, and can be fairly long-lived. They have pests, but not overly so, and are not very messy.

Western Tentiform Leafminer Phyllonorycter Elmaella, Diane G. Alston, Michael E. Reding
All Current Publications
Western tentiform leafminer populations can vary tremendously between years or even between generations within a single year. A large population in Utah's commercial fruit districts hasn't been observed since the early 2000s. Increasing resistance to organophosphate insecticides and variable effectiveness of at least six parasitic wasp species that attack the leafminer can influence the population size.

Economic And Social Impacts Of Wildfires And Invasive Plants In American Deserts: Lessons From The Great Basin, Mark W. Brunson, John Tanaka
Economic And Social Impacts Of Wildfires And Invasive Plants In American Deserts: Lessons From The Great Basin, Mark W. Brunson, John Tanaka
Articles
Research on the impacts of wildfire and invasive plants in rangelands has focused on biophysical rather than human dimensions of these environmental processes. We offer a synthetic perspective on economic and social aspects of wildfire and invasive plants in American deserts, focusing on the Great Basin because greater research attention has been given to the effects of cheatgrass expansion than to other desert wildfire/invasion cycles. We focus first on impacts at the level of the individual decision-maker, then on impacts experienced at the human community or larger socio-political scales. Economic impacts of wildfire differ from those of invasive grasses because …

Developing A Model Framework For Predicting Effects Of Woody Expansion And Fire On Ecosystem Carbon And Nitrogen In A Pinyon-Juniper Woodland, Benjamin M. Rau, Robin J. Tausch, Alicia Reiner, Dale W. Johnson, Jeanne C. Chambers, Robert R. Blank
Developing A Model Framework For Predicting Effects Of Woody Expansion And Fire On Ecosystem Carbon And Nitrogen In A Pinyon-Juniper Woodland, Benjamin M. Rau, Robin J. Tausch, Alicia Reiner, Dale W. Johnson, Jeanne C. Chambers, Robert R. Blank
Articles
Sagebrush-steppe ecosystems are one of the most threatened ecosystems in North America due to woodland expansion, wildfire, and exotic annual grass invasion. Some scientists and policy makers have suggested that woodland expansion will lead to increased carbon (C) storage on the landscape. To assess this potential we used data collected from a Joint Fire Sciences Program demonstration area to develop a Microsoft Excel™ based biomass, carbon, and nitrogen (N) spreadsheet model. The model uses input for tree cover, soil chemistry, soil physical properties, and vegetation chemistry to estimate biomass, carbon, and nitrogen accumulation on the landscape with woodland expansion. The …

Woodland Expansion's Influence On Belowground Carbon And Nitrogen In The Great Basin U.S., Benjamin M. Rau, Dale W. Johnson, Robert R. Blank, Robin J. Tausch, Bruce A. Roundy, Richard F. Miller, Todd G. Caldwell, Annmarie Lucchesi
Articles
Vegetation changes associated with climate shifts and anthropogenic disturbance can have major impacts on biogeochemical cycling and soils. Much of the Great Basin, U.S. is currently dominated by sagebrush (Artemisia tridentate (Rydb.) Boivin) ecosystems. Sagebrush ecosystems are increasingly influenced by pinyon (Pinus monophylla Torr. & Frém and Pinus edulis Engelm.) and juniper (Juniperus osteosperma Torr. and Juniperus occidentalis Hook.) expansion. Some scientists and policy makers believe that increasing woodland cover in the intermountain western U.S. offers the possibility of increased organic carbon (OC) storage on the landscape; however, little is currently known about the distribution of OC …

Propagating Bigtooth Maple, Melody R. Richards, Larry Rupp
CWEL Extension Fact Sheets
Native plants are playing an increasing role in sustainable landscapes that use fewer resources such as water and fertilizer. Unfortunately, many native plants are not available in the nursery trade, or if they are available they may only be found as seedling plants grown for the reclamation industry. Such plants are high quality and have a valuable role in the reclamation of disturbed sites such as fire-damaged areas. But, these plants by design are genetically diverse and have not been selected for typical horticultural traits such as flowering or fall color. In addition, plants produced for reclamation are usually not …

Growing transplants can be a rewarding experience if a few basic principles are followed. Experienced gardeners have a wider range of varieties to pick from if they start their own plants from seed. By selecting your own varieties you will be able to determine what grows in your area.
Leaf Number Indicates Salt Tolerance Of Young Seedling Families Of European Aspen (Populus Tremula L.) Growing In Different Soils, Lu-Min Vaario, Kim Yrjälä, Matti Rousi, Timo Sipila, Pertti Pulkkinen
Leaf Number Indicates Salt Tolerance Of Young Seedling Families Of European Aspen (Populus Tremula L.) Growing In Different Soils, Lu-Min Vaario, Kim Yrjälä, Matti Rousi, Timo Sipila, Pertti Pulkkinen
Aspen Bibliography
Soil salinity limits plant productivity and quality. We evaluated the response of 12 aspen (Populus tremula) families to salt stress in two different soils irrigated for 4-weeks with 0, 80 or 160 mM saline solution. Easily measurable characteristics such as shoot height, leaf number, dry mass as well as the distribution of sodium (Na+) ions were measured in 5-month-old aspen seedlings raised in controlled greenhouse conditions on two different soils. Growth among families varied significantly, and the interaction between family and soil type was significant. From 2–5 months, leaf number correlated with that of the first month and salin-ity tolerance. …

Drought Tolerance A Database Of Irrigation Requirements For Woody Plants Of Northern Utah, Samuel Cook, Larry Rupp
Drought Tolerance A Database Of Irrigation Requirements For Woody Plants Of Northern Utah, Samuel Cook, Larry Rupp
CWEL Extension Fact Sheets
The DROUGHT database is based on an extensive review of literature of the water requirements for woody plants adapted to the Northern Utah region. It is intended to increase the resources available to the public to incorporate water efficient principles and plants into the urban landscape. It differs from other lists of plant water requirements in that it is a review of the published literature including citations of previous research and observations. The need for a documented review is apparent as one studies the database. It can be seen that much of the water use assessments used by the industry …

Of the seven guiding principles of water-wise landscaping (a.k.a. Xeriscaping™), the most controversial involves the use of turfgrass in the landscape. At times it has seemed that water-wise landscaping might not allow for the use of turfgrasses at all.
