Ames Forester

Bright and early Sunday, October 12, 1996, 33 students and two instructors set out in cars, a truck, and vans: destined for a land full of promise, education, and trees. Steven Jungst and Richard Hall were those instructors and the students were the newest group of Forestry Fall campers. The place we were headed was Mark Twain National Forest in southern Missouri. The camp, run by the University of Missouri, was located at Poplar Bluff in the heart of the Mark Twain National Forest.

The student chapter of the Society of American Foresters (SAF) at Iowa State University had another busy year. The chapter was able to attend the state meeting last fall in the Amana Colonies which was a spin-off of the Seventh American Forest Congress. The meeting had SAF members from the states of Missouri, Illinois, Wisconsin, Minnesota, and Iowa. Former National President Robert Bosworth, and current Vice-President Bill Banzhaf also attended and shared their thoughts on the results of the Congress and where SAF needs to go from there. The student chapter also attended the spring meeting in Marshalltown with the ...


A Major Change Int.He Products Curriculum Is Proposed, Floyd Manwiller Jan 1997

A Major Change Int.He Products Curriculum Is Proposed, Floyd Manwiller

Ames Forester

It has been a long-standing philosophy of the Department of Forestry that all graduates earning a BS degree be qualified Forest Resource Managers. In keeping with this philosophy, students in the Forest Products option take many of the Resource Management courses, and to meet their interest in wood utilization, take the six products courses. This curriculum has prepared our graduates well for production positions in industry and the vast majority do take industrial positions in wood utilization rather than in Resource Management.

The agricultural landscape has four major sources of nonpoint source (NPS) pollutants. These are: 1) surface and subsurface runoff which carry sediment and agricultural chemicals to streams; 2) eroding streambanks which can contribute more than fifty percent of the sediment load to the stream; 3) field tile drains which contribute the highest concentrations of soluble agricultural chemicals to streams; and 4) livestock grazing of streamside or riparian areas which contribute to bank instability and add animal waste and pathogens to the water.


Variability In Forest Floor Mass And Nutrient Concentration Of Mature Pine-Hardwoods In The Ouachita Mountains, Hal O. Liechty, Michael G. Shelton, Edwin R. Lawson Jan 1997

Variability In Forest Floor Mass And Nutrient Concentration Of Mature Pine-Hardwoods In The Ouachita Mountains, Hal O. Liechty, Michael G. Shelton, Edwin R. Lawson

Journal of the Arkansas Academy of Science

Prior to timber harvesting, forest floor mass and nutrient concentrations in forest floor and mineral soil were determined in 24 mature, shortleaf pine (Pinus echinata Mill.)-hardwood stands occurring within the northern, eastern, southern and western sub-ecoregions of the Ouachita Mountains. The forest floor samples were collected at each of three locations representing the lower, mid, and upper slope positions within each stand. Samples of the L-(litter) and F-layers (fermentation) were collected separately. Materials from the L-layer were differentiated into hardwood foliage, pine foliage, and woody/reproductive components. Mass and nutrient concentrations of the various forest floor components were ...

The Forest Products Society, Stacy Bazal

Ames Forester

The Forest Products Society has been pushing on with new ideas to promote interest in the club for new students. One idea was the installation of a new bulletin board outside of room 263 in Bessey Hall. The board contains information on upcoming events, club announcements, and the species of the week. The species of the week display gives information about a particular species of tree. This information includes a sample of wood, a description of anatomical features, and its geographical range.

Assessing The Cost Of Best Management Practices In Arkansas, Richard A. Kluender, Robert C. Weih Jr., M. Corrigan, J. Pickett

Journal of the Arkansas Academy of Science

A geographic information system (GIS) is a set of powerful, computer-based, analytical algorithms for solving spatial data problems. Recently, due to increases in memory size, computing speed, and programming advances, personal computers have been used in spatial analysis problems. This study reports the benefits of using a PC-based GIS system to solve a common, but complicated problem in forest management: assignment of harvesting areas with harvesting exclusion zones. Two stands each from the USDA Crossett Experimental Forest, the University of Arkansas Forest, and the Ouachita National Forest (total six) were analyzed to determine the changes due to following best management ...

Community Forestry Urban And Community Forestry: Opportunities And Challenges, Janette Thompson

Ames Forester

Community Tree Management" (Forestry 475) became a regular course offering two years ago in the Department of Forestry at Iowa State University. "Urban Forestry" seminars/ special topics courses had sporadically been offered during the l 980's in response to student and faculty interest in the subject. A regular course offering in this area was added to the curriculum to provide essential background and experience for the growing number of students that are employed (both during their years at Iowa State University. and after graduation) in various aspects of urban and community forestry.

Methodology For Integrating Aerial Photography And Landsat Tm Imagery For Inventory Of Forest Land Cover, Chris W. Bennett, Robert C. Weih Jr. Jan 1997

Methodology For Integrating Aerial Photography And Landsat Tm Imagery For Inventory Of Forest Land Cover, Chris W. Bennett, Robert C. Weih Jr.

Journal of the Arkansas Academy of Science

Forest cover for 7.25 million acres (2.93 million hectares) in southeastern Georgia was characterized for the years 1988 and 1994 with the intent of assessing the efficacy of remote sensing procedures for broad scale forest inventory. Landsat-5 Thematic Mapper digital satellite scenes of seven spectral bands were obtained for winter and summer of each year and were analyzed two separate 14-band multi-temporal images. Images were geo-referenced to the universal transverse mercator (UTM) coordinate system prior to classification. Spectral classification with the 1SOCLUSTER algorithm produced 250 categories. Color infrared aerial photographs were mapped to the digital imagery and were ...

Effects Of Retained Pine And Hardwood Basal Areas On Percent Cover Of Plants Utilized By Bobwhite Quail, David G. Peitz, Philip A. Tappe, Michael G. Shelton

Journal of the Arkansas Academy of Science

Percent cover of seven forage species utilized by bobwhite quail (Colinus virginianus) was determined before thinning and 2 and 4 years after thinning a 35-year-old loblolly pine-hardwood stand. Combinations of three loblolly pine (15, 18, and 21 m2/ha) and three hardwood (0, 3.5, and 7 m2/ha) basal areas were replicated three times. Percent cover was determined for American beautyberry (Callicarpa americana), blackberry (Rubus spp.), tick trefoil (Desmodium spp.), lespedeza (Lespedeza spp.), panic grass (Panicum spp.), yellow wood sorrel (Oxalis stricta), and three-seeded mercury (Acalypha spp.). Percent cover of American beautyberry and blackberry increased with time. Tick trefoil ...

Integrating Gis And Remote Sensing With Ecosystem Research, Suzanne Wiley, Robert C. Weih Jr.

Journal of the Arkansas Academy of Science

In the Phase II Ecosystem Management Research Program in the Ouachita and Ozark National Forests, an interdisciplinary group of scientists are evaluating the effects and trade-offs of partial cutting methods in a replicated stand level study. Information from approximately 2,000 plots is being collected by more than fifty researchers during this five-year project with plans to continue data collection long term. To evaluate the effects of different management strategies and their interactions with forest resources, data must be brought into a common format and made available to all researchers. To this end, a data support system was developed which ...
