OBJECTIVES

Pacific Flyway RMP Management Objectives for Greater Yellowstone's Trumpeter Swans

 2013 Minimum Objectives2010 Actual Values% 0f Min. Obj. Achieved by 2010
September Adults53537770%
Nesting Pairs1167161%


PROBLEMS

  • Greater Yellowstone 's nesting swans are substantially below the minimum objectives managers want to achieve by 2013
  • There are no long-term management objectives for the Greater Yellowstone Flocks beyond 2013
  • There is no vision of minimum population parameters, distribution, and habitat protection that must be achieved to maintain their long-term viability
  • Nesting habitat conditions in some areas are declining due to human disturbance, water supply problems, and possibly other more subtle causes.

CONSERVATION VISION PROJECT (2011-2012)

OBJECTIVES:

  • Create a science-based "Conservation Vision" tool to assess the minimum population parameters, geographic distribution, and connectivity needed to maintain the long-term viability of the Greater Yellowstone Flocks
  • Compile and analyze all possible long-term data sets; reprint and build upon the 1987 Gale, Garton and Ball analysis
  • Identify risks to long-term viability, genetic issues, and habitat conservation needs
  • Build effective partnerships with landscape level habitat initiatives to conserve habitats needed to maintain long-term viability
  • Welcome the involvement of all Trumpeter Swan managers and researchers and build new partnerships with universities, conservation groups, and habitat conservation initiatives.

PROJECTS:

NEST MONITORING

FIND DETAILS IN TTSS CITIZEN SCIENCE PROGRAM: TRUMPETER WATCH: GYTSI
  • Monitoring nesting in Idaho' care area and the Wyoming portion of the Caribou-Targhee NF
  • Long-term trend analysis and coordination of habitat improvement opportunities with IDFG, USFS, and other agencies

CENTENNIAL VALLEY, MONTANA - NEST HABITAT CONSERVATION

  • Working with local ranchers and agencies to protect and improve historic nest territories on private and BLM lands in the Centennial Valley
  • Evaluating characteristics of key nesting territories and possible factors causing recent reduced cygnet production
  • Evaluating Lima Reservoir's molting habitat and coordinating with partners to maintain its exceptional habitat quality.

YNP - EARLY TRUMPETER SWAN STUDIES REVIEW

  • Conduct an analysis of early nesting studies and efforts by George Melendez Wright that saved the last Greater Yellowstone Trumpeters
  • Reconstruct early distribution and seasonal movements of Trumpeters based upon historical studies
