A Decision Support System for the St. Croix National Scenic Riverway
Entry ID: USGS_DDS_St._Croix
Abstract: The Riverway is at the center of intense economic, political, legal,
recreational, and value conflicts because of its proximity to the growing
metropolitan area of Minneapolis and St. Paul, Minnesota. Park Service staff
need to assemble and use the best available data to make, justify, and enforce
resource decisions. This decision support system (DSS) application addresses
these National Park ... Service (NPS) needs in an easy-to-use application that
requires no ancillary geographic information system (GIS) software or advanced
GIS knowledge to use effectively.
The St. Croix National Scenic Riverway Data Viewer 1.0 is a PC-based
application developed in Visual Basic 6 and distributed on CD-ROM with a
standard setup program. The DSS as it exists now combines the physical features
of the River Basin into one program, accessible from the manager's desktop.
The second phase of this DSS project is the development of a nonspatial
database of biological data. This database, built with Microsoft Access, is the
storage mechanism for the many biological sampling points that exist in the St.
Croix Riverway. The database facilitates data entry, update, and query of
biological data records. In addition, it is possible to output a subset of
database records (points) in a format viewable by industry-standard GIS
software. The second phase of the DSS is currently under way, as we are
gathering data on native freshwater mussels, rare plants, and rare animals from
a variety of sources (reports, peer-reviewed literature, databases). The data
from each of these themes are being placed into a database with more than 100
fields of descriptive data relative to each theme (i.e., water depth, substrate
composition, density, plot size, date of most recent observation).
In parallel with the Data Viewer application development, a UMESC study is
under way to evaluate the effects of ammonia on unionid mussels in the St.
Croix National Scenic Riverway. Data from this study will be a valuable
addition to the DSS, as it will provide additional spatial layers and new
scientific knowledge about these organisms.
