Herr, A.M. and L. Queen. 1991. Remote sensing approach to avian conservation: A greater sandhill crane model. Final report submitted to the Nongame Wildlife Program, Minnesota Department of Natural Resources. 29 pp.
The goal of this project was to develop a descriptive GIS model to identify potentially suitable nesting habitat of Greater Sandhill Cranes in northwestern Minnesota. Four primary objectives of the project were: (1) to produce a digital map of plant communities in the study area from Landsat-5 Thematic Mapper data to be used as a primary data layer in the GIS model, (2) to characterize the habitat for twenty-two known nest sites in Espelie and Veldt townships of Marshall County using the EPPL7 GIS software package, (3) to identify potentially suitable nesting habitat in Poplar Grove and Golden Valley townships of Roseau County using the descriptive model developed from the nest site characteristics studied in Espelie and Veldt, and (4) to compare the results of the model in Poplar Grove and Golden Valley to the locations of ten known nest sites.
