An Auspicious Beginning - A Favorable Setting A Propitious Forestry Summer Camp

The 1984 Forestry Camp was held at Camp Cassaway on the Chippewa National Forest in northcentral Minnesota

From Iowa to Montana and Back Again: Forestry Camp- 1987

The 1987 Forestry Camp was held from June 27 through August 5, 1987 at the Lubrecht Experimental Forest, Greenough, Montana. The late start was due to another group slated to use the Lubrecht for the first three weeks in June. ISU foresters have used this University of Montana facility several times over the 73 years of forestry camp. This year, as in past years the students and staff enjoyed the hospitality of the staff and natural resources professionals who helped with tours or field exercises. The success of the camp was due largely to three factors: 1) a great bunch of students eager to learn and willing to endure our high expectations, 2) exceptional support and aid from the Lubrecht staff of Mr. Hank Goetz, Manager, Mr. Frank Maas, Assistant Manager, and Dr. Robert (Bob) Pfister, Project Director of the Mission Oriented Research Project (MORP), and 3) a dedicated, enthusiastic staff consisting of Dr. Richard (Dick) Schultz, Dr. Monlin Kuo and myself

Forecasts of Wastepaper Supply and Consumption In The United States To 1985

Recycling of wastepaper is a partial solution to the solid waste management problem and a source of fibrous material in the production of paper and board products. Unlike virgin fiber, wastepaper is the result of past paper and board consumption. To consider these important facts and others affecting wastepaper supply and consumption, a model of the paper and board industry inclusive of wastepaper recycling was constructed. The results of application of this model showed that wastepaper supply and consumption can vary widely depending on the future recovery rates and utilization levels of wastepaper by the paper industry. By assuming the most optimistic wastepaper recovery and utilization increases by 1985, a domestic wastepaper supply shortfall is forecasted. However, the most likely future wastepaper utilization scenario indicates a surplus of wastepaper by 1985 given average recovery rates. The model can be used to consider a broad range of wastepaper recovery and utilization situations and alternative economic growth rates

Agroforestry- Growing Crops, Livestock, and Trees on Iowa Farms and the Midwest

Agroforestry is formally defined as a land-use system that intentionally combines trees or shrubs with annual plants and/or animals on the same land area. The combination may exist at the same time or in a sequential fashion (Agroforestry Systems, 1982). The production of diverse agronomic and forestry outputs (hence agro-forestry ) on the same land area is an important feature that may be very practical in trying to strengthen and diversify the primarily agricultural economy of Iowa. While agroforestry is still an emerging food, fiber, and industrial material production system in the American Midwest, it has been proven to be a sustainable system of land use in many parts of the world. Sustainability implies that this land use system is a healthy, economically viable, and environmentally protective technology

Computers in Forestry- A Modem Tool

Foresters, like other professionals, are using computers more and more frequently in their daily decision-making routine. Modern computers are lighter, more powerful and offer more tailor-made means to solve forestry-related problems than they did only a few years ago. When Drs. Atanasoff and Berry invented the first electronic digital computer here at Iowa State University in 1939, they probably had no idea of the sweeping impact this tool would have on mankind. For sure, they did not envision dirt foresters or timber beasts using computers to process inventory data, or project the growth and development of mixed hardwood stands, or determine the cutting budget for a one million acre National Forest for the next ten years or more

Evaluation of interactions within a shelterbelt agroecosystem

A tree shelterbeit comprised of four rows of hybrid poplars was established near Ogden, Iowa in 1992 to evaluate shelterbeit characteristics and impacts on soil water content and crop growth andyieid. Major emphasis was on testing crops of corn and soybeans. The first three years saw little effects from the shelterbeit, and data from these years will be used to develop a baseline for future measurements. In the fourth and fifth years, corn yield patterns suggested that the shelterbeit increases yields in the zone leeward from the shelterbeit. Soybeans have not shown a response to the presence of the shelterbeit

Forage and Tree Experiment (FATE)

Trees are becoming an increasingly important component of the Iowa landscape. For tree plantings to be more common in Iowa two major problems related to establishment must be overcome: (1) intense weed competition and (2) a lack of market or non-market values for several years for newly planted trees. To develop information that addresses these problems, a research project was initiated during the spring of 1998 at the ISU Rhodes Research Farm. The objectives of the project are: (i) to evaluate the influence of seven weed control treatments [four small grain/forage crop combinations (oats and red fescue; oats, red fescue, and red clover; and oats, orchardgrass, and red clover; red clover and hairy vetch), one herbicide treatment (conventional mix of preemergents with additional control from RoundUp), mowing, and no treatment] on the survival and growth of two groups of tree species (fast-growing hardwoods [two poplar clones and silver maple] and highvalue hardwoods [red oak and black walnut as seedlings and from seed]); (ii) to evaluate the influence of seedlings of the tree species on the productivity of small grain/forage crop combinations, and (iii) to determine the cost effectiveness of planting trees with different weed control techniques

Improving tree establishment with forage crops

Weed competition and economics are two common barriers to Iowa farmers\u27 investing in tree plantings. This project examined seven weed control strategies and investigated productivity of small grain/forage combinations raised with trees in an effort to suggest management options that would encourage tree planting in the state

Behavioral and clinical characteristics of people receiving medical care for HIV infection in an outpatient facility in Sicily, Italy

Aim: The authors examined a cohort of HIV-positive outpatients at the AIDS Center of Palermo University in Italy in order to identify factors related to the frequency of their visits to the outpatient facility for health care services. Methods: Two hundred and twenty-four HIV-infected subjects were enrolled in the study. Demographic and HIV disease characteristics were recorded and assessed with the number of days accessed to our outpatients unit in univariate and multivariate analyses. The potential relationship with immunological status was also analyzed stratifying the patients into groups according to their CD4+ T-cell counts ( 65500 vs, \u2c2500/mm3, and 65200 vs < 200/mm3). Results: Both univariate and multivariate analyses showed that duration of antiretroviral therapy, \u2c25 years and hypertension were significantly associated with a CD4+ T-cell count of, \u2c2500/mm3, whereas geographic origin (Africa) was associated with a CD4+ T-cell count of, \u2c2200/mm3. Mean number of days the patients sought access to day-care services for laboratory tests was negatively associated with CD4+ T-cell count. Conclusion: Patients with low CD4+ T-cell counts showed higher use of health care services, demonstrating how early HIV diagnosis can help to reduce health care costs. The CD4+ T-cell cut-off of 200 cells emphasizes the importance of identifying and managing HIV infection among hard-to-reach groups like vulnerable migrants. In our sle, the illegal status of immigrants does not influence the management of their HIV/AIDS condition, but the lack of European health card that documents the current antiretroviral status, could interfere with the efforts to eradicate AIDS. A better understanding of the major determinants of HIV treatment costs has led to appropriate large-scale actions, which in turn has increased resources and expanded intervention programs. Further guidance should be offered to hard-to-reach groups in order to improve early AIDS diagnosis, and procedures for identifying and managing these vulnerable subjects should be made available to care commissioners and service providers
