Solving problems related to whooping cranes without reference to other species will probably lead to additional problems.

Knowledge and data on how the various species may interact with each other through habitat manipulation are especially important. When managers clear woodland for whooping crane habitat, for example, there appear to be favorable outcomes for the crane population, but there is little knowledge about the effects of such actions on other species, so continued monitoring and measurement efforts are required. The committee also recognizes the importance of long-term records and data in reaching conclusions about whooping crane use of the central Platte River. Because of the annual fluctuations in the river processes and in crane use, trends of only a few years are not likely to be informative regarding longer-term, decade-long trends, so analysis and prediction require datasets on birds and environmental conditions that exceed a few years.
