Structure And Development Of Pitch Canker Infected Monterey Pine Stands At Año Nuevo, California, Douglas D. Piirto, Sauli Valkonen

Natural Resources Management and Environmental Sciences

The sustainability of indigenous Monterey pine (Pinus radiata D. Don)at Ano Nuevo stands in the central coast of California was examined. The foremost management objective in these stands is to establish and maintain stand structures that ensure a sustainable presence of the species in terms of uneven-aged management. The major threats are the proliferation of shade-tolerant tree species and the pitch canker ( Fusarium circinatum) disease. The study was based on data from 17 systematically placed sample plots, measured once, in one stand with a very high degree of variation in stand structure and species composition. The results …

Silvicultural Best Management Practice Compliance Monitoring Programs In The Southern United States, Amanda L. Husak, Stephen C. Grado, Steven H. Bullard, Steverson O. Moffat

Faculty Publications

Passage of the Clean Water Act (CWA) of 1972 prompted states to invest significant resources to develop programs to control nonpoint source (NPS) pollution from forestry and other activities. Forestry-related agencies and organizations have since developed silvicultural best management practice (BMP) guidelines to reduce NPS pollution, maintain stream integrity, and meet state water quality standards. To determine the effectiveness and implementation level of best management practices (BMP) on public and private forestland, states further developed and implemented their BMP compliance monitoring programs. This study documents the similarities and differences in efforts, methods, resources, and expenditures among BMP compliance monitoring programs …

How Are Investment Returns Affected By Competition Control And Southern Oak Seedling Survival?, D. L. Grebner, A. W. Ezall, D. A. Gaddis, Steven H. Bullard

Faculty Publications

Increasing numbers of landowners are establishing hardwood plantations to satisfy their management objectives. Despite a dearth of research on competition control and its effects on initial hardwood plantation survival and investment returns, this study examines alternative competition control regimes for southern oak establishment. The analysis includes estimates of land expectation value for comparing alternatives. Our results suggest that greater returns can be achieved for southern oaks during both good and bad rainfall years, using methods that maximize survival through competition control.

Runoff And Sediment Losses From Annual And Unusual Storm Events From The Alto Experimental Watersheds, Texas: 23 Years After Silvicultural Treatments, Matthew W. Mcbroom, R Scott Beasley, Mingteh Chang, Brian Gowin, George G. Ice

Faculty Publications

Evaluating the potential impacts of intensive silvicultural practices on water quality is critical for establishing the long-term sustainability of contemporary forest management practices. From 1979 to 1985, a study involving nine small (~2.5 ha) forested watersheds was conducted near Alto, Texas in the upper western Gulf-Coastal Plain to evaluate the impacts then-current silvicultural practices on water quality. In the years following the study, silvicultural Best Management Practices (BMPs) including Streamside Management Zones (SMZs) and other erosion control practices evolved and questions arose about the applicability of earlier results to current practices. In 1999, these same watersheds were reinstrumented to evaluate …

Effectiveness Of Delayed Brush Cutting And Herbicide Treatments For Vegetation Control In A Seven-Year-Old Jack Pine Plantation In Northwestern Ontario, Canada, Azim U. Mallik, F. Wayne Bell, Yanli Gong

Aspen Bibliography

Efficacy of three conifer release treatments, i) single application of glyphosate (Vision™) herbicide, ii) multiple application of glyphosate herbicide, and iii) motor-manual brush cutting for controlling competing plants, particularly trembling aspen (Populus tremuloides), pin cherry (Prunus pensylvanica), green alder (Alnus viridis spp. crispa), and beaked hazel (Corylus cornuta spp. cornuta), was studied in a seven-year-old jack pine (Pinus banksiana) plantation in northwestern Ontario, Canada. The single and multiple glyphosate applications were equally effective in controlling trembling aspen and pin cherry, causing over 90% stem mortality. The brushsaw treatment caused an initial decrease followed by an increase in stem density of …

Site Index Conversion Equations For Mixed Trembling Aspen And White Spruce Stands In Northern British Columbia, Gordon Nigh

Aspen Bibliography

White spruce and trembling aspen are two important commercial species in British Columbia. They often grow in association, particularly in the Boreal White and Black Spruce and Sub-Boreal Spruce biogeoclimatic zones. Site index conversion equations are useful for estimating the site index of one species from the site index of another species. This study fills a need for site index conversion equations for mixed spruce/aspen stands. Seventy 0.01 ha study plots were established in mixed spruce/aspen stands. One site tree of each species was selected from each plot. The height and breast height ages of the site trees were measured …

Quaking Aspen Reproduce From Seed After Wildfire In The Mountains Of Southeastern Arizona, Ronald D. Quinn, Lin Wu

Aspen Bibliography

Quaking aspen regenerated from seed after a stand replacement wildfire in the Chiricahua Mountains of southeastern Arizona. The wildfire had created gaps in the canopy so that aspen were able to establish from seed. Seedlings were found at a mean density of 0.17 m–2, 30 m or more from the nearest potential seed trees. Six clumps of aspen seedlings contained 18–186 trees, occupying areas of 145–500 square meters at densities of 0.09-0.27 m–2. White-tailed deer (Odocoileus virginianus) browsed 14.3% of the seedlings. Occasional sexual reproduction of aspen may be a general trait of the species throughout the western portion of …

Rates Of Return On Silvicultural Practices, Steven H. Bullard, Bobb L. Karr

Faculty Publications

Anticipated rates of return can help landowners and forest managers evaluate hardwood control and many other stand treatments. A simple microcomputer model is discussed which displays rates of return for specific stand treatment conditions. The program can be used before or after taxes and with or without inflation. The model displays rates of return for ranges of silvicultural treatment costs and expected harvest value increases, thus providing information for evaluating treatments where growth responses or future prices are difficult to estimate.
