Note: The following is an overview of the ESGBP’s five annual reports (1994 through 1998). You also have the option of viewing the full text of the 1997 report (available in a PDF version), or the 1998 report (also available in PDF format).

OVERVIEW OF YEARLY REPORTS

The Eastern Slopes Grizzly Bear Project has produced an annual report for each year of its existence thus far (1994-1997 inclusive). Each report contains information for that particular year on:

  • Grizzly bear capture data in the Bow River Watershed.
  • Grizzly bear trapping success in the Bow River Watershed.
  • Status of all grizzly bears captured in the Bow River Watershed.
  • Unduplicated grizzly bear females with cubs of the year in the Bow River Watershed.
  • Reproductive status of known female grizzly bears in the Bow River Watershed.
  • Summary of grizzly bear mortalities in the Bow River Watershed.
  • Summary of grizzly bear translocations in the Bow River Watershed.

In addition to the yearly information, each annual report has specific information on various aspects of our research:
Year 1 (1994)

  • The distribution of mtDNA lineages and genetic diversity (h) within North American brown bear populations (taken from Waits et al. 1996, with additional new data).
  • Serum chemistry analysis

Year 3 (1996)
