This was the 13th year of goshawk Nest Monitoring in the Cranberry and Kispiox Watersheds. This dataset provides us with a unique record of the annual breeding success of a species that has been identified as a focal indicator of how well we are managing our forest ecosystem through the application of “Coarse Filter” management practices (goshawks are dependent on the abundance and availability of forest birds and mammals as prey). Since 1999 in addition to the overall status of the population, monitoring has also been designed to determine the impact of harvesting within nest areas, on the continued use and breeding success of goshawks using these areas.
Goshawk nest areas were surveyed for the presence of breeding birds at the nestling and fledgling stages, both by looking for sign (active nests, feathers, whitewash, etc,) and by the use of standardized call playback techniques. In those nest areas where sign, and/or birds were seen, followup surveys were conducted to determine if the birds were breeding.
A total of 27 nest areas were monitored, 13 control sites (no harvesting within the Nest Area) and 14 treatment sites (harvesting had taken place within the nest area). Goshawks were found in 6 nest areas (4 control sites, 2 treatment), and 3 of these had active nests(2 control, 1 treatment).
