Dallas
County Farm Project
Landscape Resource Management
LA 562
Studio in Resource Conservation and Management
Instructor: Paul F. Anderson
Background
Project background
From March through May of 2001, seven students at Iowa State University
studied the Dallas County Farm and Care Facility. Students responded to a
request from Jeff Logsdon (director of the Dallas County Conservation
Department) to study the Farm’s landscape, stakeholders, and facilities.
During the brief study period, students completed the following steps:
- Visited the Farm several times
- Interviewed stakeholders (Farm managers, county officials, county
residents)
- Researched background information about the Farm and similar
institutions
- Hosted at the Farm a charrette/workshop involving eight guests
- Developed landscape resource management recommendations
Each student selected a topic or aspect of the Farm based on their own
interests and learning objectives. Their reports summarize their landscape
management recommendations.

Course background
The students were enrolled in Landscape Resource Conservation and
Management (LA 562) taught by Paul Anderson, professor of Landscape
Architecture and Agronomy at Iowa State University. The ISU 1999-2001 Course
Catalog includes the following course description:
Developing plans and policies that feature ecological landscape
description, planning, and resource conservation. Hands-on field experience
with professional resource planners and managers.
Purposes of the course are to (1) help prepare students for making decisions
about landscape management practices and (2) help prepare students to create
landscape management plans that include practices and policies. Learning
objectives of the course include the following:
- Create awareness and understanding of landscape management issues
- Develop abilities to create landscape management plans and policies
- Understand the implications of landscape management practices
During the first half of the semester, students completed reading
assignments, presented ideas and information to each other, discussed landscape
resource management issues, listened to guest speakers, and wrote reaction
papers. Topics included current issues in landscape resource management,
developing landscape management plan reports, roles of landscape managers,
public involvement in landscape management processes, technology for landscape
management, and issues of sustainable agriculture.
This study of the Dallas County Farm and Care Facility provides students with
hands-on experiences in applying concepts, procedures, and practices they
studied in the first half of the semester. This study provided an ideal
opportunity for student learning about the complexities and realities of
managing the landscape for people while maintaining environmental quality. After
much study and soul-searching, the students feel as though they have just
scratched the surface though this study.
Acknowledgements
The students felt fortunate that many people from Dallas County were both
generous and gracious in helping them learn about management of the Dallas
County Farm and Care Facility. These people included Karen Smith (Facility
administrator); David Boots (Farm manager); Chris Nelson (Farm advisory
committee member); Peter Malmberg (Conservation Department history specialist);
and Marvin Shirley, Alice Wicker, and Julius Little (members of the Dallas
County Board of Supervisors).
As he has done so many times before, Jeff Logsdon (Conservation Department
director) suggested that students be involved in studying the landscape of
Dallas County. He deserves special thanks for providing students with valuable
experiences as they prepare for their professional careers.
Barb, James, Kyle, Luke, Marcela, Melissa, Strauss – thanks for making this
study so enjoyable.
Oh…and thanks, Karen, for the great food!

GIS modeling
The GIS database used for modeling the Dallas County Farm included the
following themes:
- Farm boundary
- Parcel acquisition (1869-1907)
- Public land survey system (IDNR)
- Aerial photo (Sidwell 1990)
- Aerial photo (USGS 9/30/96)
- Quadrangle (USGS DRG)
- Surface elevation contours (USGS)
- Slope aspect
- Census (IDNR 1990)
|
- Roads and highways (ODNR)
- Land use/land cover (7/2000)
- Historic vegetation (GLO 1849)
- National Wetland Inventory (USFWS)
- Soil mapping units (ISU)
- Soil spot conditions (ISU)
- Soil drainage features (ISU)
- Rivers and streams (IDNR)
|
Several themes and additional attributes were developed locally during or
prior to the semester project:
- Farm boundary (P. Anderson, July 2000)
- Slope aspect (S. Morgan, July 2000)
- Land use/land cover (P. Anderson, July 2000)
- Soil attributes (B. Olson, July 2000)
- Parcel acquisition (P. Anderson, April 2001)
From the database, the following descriptive and predictive GIS models were developed:
- Property acquisition
- Land use/land cover
- Historic vegetation
- Native vegetation
- Slope aspect
- Slope steepness
- Landscape position
- Flooding frequency
- Woodland erosion hazard
|
- Soil erosion hazard
- Suitability for campgrounds
- Suitability for dwellings
- Suitability for agriculture (CSR)
- Suitability for paths and trails
- Suitability for streets and roads
- Suitability for septic filter fields
- Suitability for sewage lagoons
- Suitability for wetland wildlife

Here's a sample of some of the GIS models used by class members:
   
   
Management reports
After interviewing Farm managers and studying the Farm's background and
current status, each student selected a management issue to study in more
detail. Each student prepared a written report with their management
practices, strategies, and recommendations. The students' reports are
available in Adobe Acrobat PDF format:
Photographic study
Strauss Hsieh took photographs of the Dallas County Farm and Care Facility
during more than five site visits during April and May. A selection of his
photographs follows.
