Welcome to the decision support system for the Rocky Mountain Population of trumpeter swans.  This system will simulate the distribution of trumpeter swans across 27 sites, primarily in the United States. To run this system you will need information about wetland habitat and swans at at least one of six specific sites.  You will also be asked for the time period for which you are interested.  The system begins by looking up the actual, known number of swans across all 27 sites for the starting time period that you choose.  Then, using the knowledge embedded in the system collected from various wetland and waterfowl experts from across the country, the system will simulate a distribution of those swans, in seasonal time steps, for the subsequent year(s) until the ending year is reached.  During this process, you may be prompted for additional information that the system may need to reach its conclusions.

Embedded in the decision support system is ecological information about managing montane, semipermanent, palustrine, emergent wetlands; about breeding habitat quality for trumpeter swans; about principles of flyway management for migratory birds; and about probabilities of movement among geographic areas by swans.  However, in most cases it will need additional information from you, especially about wetland conditions for the time period in which you are interested.
