Oaks In The Landscape, Sheriden M. Hansen, Jaydee Gunnell, Andra Emmertson
All Current Publications
Oak trees (Quercus sp.) are generally a tough, drought tolerant, and beautiful addition to Utah landscapes. There are roughly 450 known species of oak, with about 60 cultivars that are native to North America. Oaks are known for slow growth, sturdiness, and easy care and can be used to create a focal point and ornamental interest in the landscape. This fact sheet reviews recommended cultivars for the Intermountain West and how to grow them, including site selection and preparation, planting and spacing, irrigation, and addressing challenges such as weeds, fertilization, pruning, and diseases and pests.

The Site Evaluation Of Quercus Alba Metabolites, Zachary Alexander Byrd
Theses and Dissertations--Plant and Soil Sciences
Quercus alba has been the prominent tree species utilized in the spirits industry for decades. Of its many qualities, the ability to impart desirable flavors on spirits combined with its natural abundance makes it the ideal choice for barrels. Creating barrels is a uniform process, but variability still exists in aged spirits even when all other parameters are controlled. In this thesis, I explore how the origin of Quercus alba influences metabolite variability.
Quercus alba is a resilient species that can grow in many climates. This is seen through Quercus alba’s vast growing range, of which barrel quality white oak …
Early Tree Growth In Reclaimed Mine Soils In Appalachia Usa, Kara Dallaire, Jefferey Skousen
Early Tree Growth In Reclaimed Mine Soils In Appalachia Usa, Kara Dallaire, Jefferey Skousen
Faculty & Staff Scholarship
Abstract: Surface mining disturbs hundreds of hectares of land every year in many areas of the world, thereby altering valuable, ecologically-diverse forests. Reforestation of these areas after mining helps to restore ecosystem functions and land value. In Appalachia, native topsoil is normally replaced on the surface during reclamation, but waivers allow for brown and gray sandstone materials to be used as topsoil substitutes. Numerous studies report the growth of trees in these substitute mine soil materials, but few studies have compared the height of trees grown in reclaimed mine soils to the heights of trees grown in native soils. This …

Oak Galls: A Strange Biology Indeed!, W. John Hayden
Biology Faculty Publications
Anyone who takes the time to look closely at several branches of oak will soon find one or another peculiar anomaly among the leaves and twigs. One can easily find structures resembling Ping-Pong balls, hard knots, fluffy tufts, horns—either single or clustered, or irregular thickenings, to mention just a few possibilities. These abnormal growths are galls, structures caused by the presence of small insect larvae living inside the tissue of the plant. Galls can be found on a wide variety of plants. They are common, for example, on the stems of goldenrods, and the leaves of maples, but oaks are …
White Oak Part Of Global Oak Presence, W. John Hayden
White Oak Part Of Global Oak Presence, W. John Hayden
Biology Faculty Publications
As we act locally celebrating white oak, Quercus alba, as the 2011 VNPS Wildflower of the Year, it is perhaps appropriate to think globally for a few moments and consider the breadth of diversity encompassed by the oaks. Quercus is a big genus, easily the largest in its family, the Fagaceae. Approximately 400 species of oak are known, and they are widely distributed in the northern hemisphere. We tend to think of oaks as temperate zone trees, but in the New World, their range extends south through the mountains of Central America to Colombia and in the Old World, …

Hybrid Oaks: Full Of Vexation And Wonder, W. John Hayden
Biology Faculty Publications
Distinguishing different species of oak in the forests of eastern North America can be challenging. For one thing, there are simply a lot of different species to sort out. A recent reference (Stein et al. 2003), describes 50 species in the genus Quercusoccurring naturally east of the 100th meridian, and 90 species are distinguished for all of North America north of Mexico (Nixon 1997). With so many species to parse, confident identification requires careful study of leaves, stem and leaf hairiness, and fully mature acorns with their caps. But care is not always enough, because in addition to the …
