Nitrogen Cycling Responses To Mountain Pine Beetle Disturbance In A High Elevation Whitebark Pine Ecosystem, Megan P. Keville, Sasha C. Reed, Cory C. Cleveland Jun 2013

Nitrogen Cycling Responses To Mountain Pine Beetle Disturbance In A High Elevation Whitebark Pine Ecosystem, Megan P. Keville, Sasha C. Reed, Cory C. Cleveland

Ecosystem and Conservation Sciences Faculty Publications

Ecological disturbances can significantly affect biogeochemical cycles in terrestrial ecosystems, but the biogeochemical consequences of the extensive mountain pine beetle outbreak in high elevation whitebark pine (WbP) (Pinus albicaulis) ecosystems of western North America have not been previously investigated. Mountain pine beetle attack has driven widespread WbP mortality, which could drive shifts in both the pools and fluxes of nitrogen (N) within these ecosystems. Because N availability can limit forest regrowth, understanding how beetle-induced mortality affects N cycling in WbP stands may be critical to understanding the trajectory of ecosystem recovery. Thus, we measured above- and belowground N …

Past, Present, And Future Old Growth In Frequent-Fire Conifer Forests Of The Western United States, Scott R. Abella, W. Wallace Covington, Peter Z. Fule, Leigh B. Lentile, Andrew J. Sanchez Meador, Penelope Morgan Jan 2007

Past, Present, And Future Old Growth In Frequent-Fire Conifer Forests Of The Western United States, Scott R. Abella, W. Wallace Covington, Peter Z. Fule, Leigh B. Lentile, Andrew J. Sanchez Meador, Penelope Morgan

Public Policy and Leadership Faculty Publications

Old growth in the frequent-fire conifer forests of the western United States, such as those containing ponderosa pine (Pinus ponderosa), Jeffrey pine (P. jeffreyi), giant sequoia (Sequioa giganteum) and other species, has undergone major changes since Euro-American settlement. Understanding past changes and anticipating future changes under different potential management scenarios are fundamental to developing ecologically based fuel reduction or ecological restoration treatments. Some of the many changes that have occurred in these forests include shifts from historically frequent surface fire to no fire or to stand-replacing fire regimes, increases in tree density, increased abundance of fire-intolerant trees, decreases in understory …


Standard-Level Herbivory In An Old-Growth Conifer Forest Canopy, David C. Shaw, Kristina A. Ernest, H. Bruce Rinker, Margaret D. Lowman Dec 2006

Standard-Level Herbivory In An Old-Growth Conifer Forest Canopy, David C. Shaw, Kristina A. Ernest, H. Bruce Rinker, Margaret D. Lowman

All Faculty Scholarship for the College of the Sciences

Herbivory is an important ecological process in forest canopies but is difficult to measure, especially for whole stands. We used the Wind River Canopy Crane in Washington State to access 101 randomly-located sample points throughout the forest canopy. This provided a relatively quick and convenient way to estimate herbivory for a whole stand. The overall level of herbivory was estimated at 1.6% of leaf area. The distribution was strongly skewed to the lower canopy where broad-leafed species experienced higher levels of herbivory. Herbivory averaged 0.3% in conifers and 13.5% in broad-leafed species. Fully half of the sample points had no …

Ec96-1768 Windbreak Management, James R. Brandle, Craig Stange

University of Nebraska-Lincoln Extension: Historical Materials

The windbreaks on your farm are an important part of the agricultural landscape. They provide protection for the farmstead, livestock, and crops; provide habitat for wildlife; and contribute to an overall healthy environment for you and your family. They are living systems with youth, maturity, and old age. Like any other living thing they need proper care and management in order to continue to function at their best.

Windbreak management requires an understanding of how your windbreak works. Your goal is to maintain the health and vigor of individual trees and shrubs while maintaining the overall structure of the windbreak …


Ec94-1766 Windbreaks For Livestock Operations, James R. Brandle, Vernon Quam, Ladon Johnson, Bruce Wight Jan 1994

Ec94-1766 Windbreaks For Livestock Operations, James R. Brandle, Vernon Quam, Ladon Johnson, Bruce Wight

University of Nebraska-Lincoln Extension: Historical Materials

Windbreaks play an important role in the protection of livestock, particularly in young animals and in areas with cold northerly winds during the winter and early spring. Properly placed windbreaks can provide benefits to feedlots, livestock pastures, and calving areas. Reducing wind speed in winter lowers animal stress, improves animal health, and increases feeding efficiency. Livestock windbreaks provide significant amounts of wildlife habitat, protect the working environment in and around the livestock area, and screen noise and odors associated with livestock operations.

Specific needs of animals dictate that special attention be given to access, snow storage, and drainage when planning …

Tall Shrub Dynamics In Northern Minnesota Aspen And Conifer Forests, J.C. Balogh, D.F. Grigal

Aspen Bibliography

Tall shrubs are a dynamic component of upland forests in the Lake States (Balogh 1983, Dunn 1986, Ohmann and Ream 1971). They are an integral part of forest element cycles, competitors with overstory for growth and reproduction, essential to post-harvest site stabilization, and a source of wildlife cover and browse (Comerford and White 1977, Dunn 1986, Robinette 1972, Tappeiner 1971).

Streamline Herbicide Release Of Red Pine (Pinus Resinosa), L.S. Brooks, B.S. Jones

Aspen Bibliography

Conifer management in the lake States requires the land manager have a diverse set of tools to accomplish the task of plantation establishment and survival. Methods are almost as variable as the soils of the region, which as remnants of ancient seas, volcanos and more recent glaciers. Terrain, soil profile, drainage, aspect and climate are some of the basic factors contributing to the diversity of sites and management regimes practices in the region. Herbicides are an important part of successful conifer management regimes. Approximately 70M forested acres are treated annually in MN, WI and the Upper Peninsula of MI.

Ec82-1738 Tree Planting Guide, William R. Lovett, Bruce E. Bolander

University of Nebraska-Lincoln Extension: Historical Materials

Site Preparation

Proper site preparation is essential to your tree planting operation, and varies with the different climates and soil types.

Chemical Control: On sandy soils, rough terrain, or other highly erodible sites, tillage is not recommended. Chemical weed and/or grass killers may be applied to the site in the fall or before planting in the spring.

Summer Fallow: This practice is recommended on heavy soil in western Nebraska to conserve soil moisture. This may be accomplished with the aid of occasional disking, subsurface tillage, or chemicals to control weeds.

Fall Tillage: In the eastern areas of the state fall …

G77-380 Growing Conifers From Seed, Constance A. Harrington Jan 1977

G77-380 Growing Conifers From Seed, Constance A. Harrington

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide discusses how to grow conifers from seed, including technical terms, collecting and storing seed, and planting and care of the trees.

Growing your own conifer trees from seed is fun and gives you the satisfaction of doing it yourself. The pioneers had to be self-reliant. Many of the old trees in Nebraska were started from seeds the pioneers brought with them or ordered from nurseries in the east or Europe. We are fortunate in having nurseries available to supply a wide variety of planting stock. However, many people are still interested in growing their own seedlings. You may …
