ACKNOWLEDGMENTS

A very successful seventh field season would not have been possible without the dedication of field biologists S. Ciancone, C. Hague, M. Koppang and S. Stevens. Their efforts were augmented through the largely volunteer support of C. Campbell. Assistance in coordination of field staff was provided by A. Dibb, S. Donelon and T. Hurd. Trapping was conducted by C. Mamo, the Banff National Park Warden Service and Alberta Natural Resources Service. Veterinary care was provided by Dr. Todd Shury. Several Alberta Conservation Officers and Banff National Park Wardens provided invaluable safety backup, field assistance and logistical support through all stages of monitoring. Exemplary flying skills were provided by Alpine Helicopters of Canmore and fixed wing pilot M. Dupuis of Wildlife Observation Air Services.

GOALS AND OBJECTIVES

During 2001 our research continued to focus on gathering basic reproductive and mortality data for analysis of demographic parameters. Another important research question we focused on is how do grizzly bear’s spatial and temporal use patterns differ in areas of high human presence compared to areas with low human presence in a landscape, some of which is dominated by tourism activities? Our situation is unique in that no other grizzly bear study area in North America has both a high volume transcontentinal highway and railway dissecting occupied grizzly bear habitat along with intensive tourism. Analysis has never been done on the effects of such levels of human presence on grizzly bears. One important question is the extent to which the Bow River Valley continues to function as a major movement corridor for bears providing connectivity between habitats.

The overall goal of ESGBP research is to understand how developments and human-induced mortality impact grizzly bears. Specific research objectives include:

1. Determine the basic demographic parameters for the grizzly bear population within the study area.
2. Detect spatial and temporal activity patterns of bears given various levels of human influences.
3. Determine how the distribution of humans affects a bear’s ability to use the landscape.
4. Determine if population connectivity is being impeded by major transportation corridors.
5. Determine what adjustments to human activities would give bears better access to resources.
6. Suggest management alternatives for integrating land uses compatible with bear habitat and survival needs for the study area.

STUDY AREA

The area of interest remains unchanged from year 1 with the approximately 11,400 km² Bow River Watershed, from its headwaters to approximately where it meets the prairies, as the core study area. The greater study area defined by the movement of radio-collared bears is about 22,000 km² or roughly twice the size of the core study area. At the largest scale our research encompasses the 42,000 km² Central Rockies Ecosystem (Komex International 1995).

METHODS

Methods for both the capture and monitoring of bears remain unchanged from the detailed description found in the year 1 progress report (Gibeau and Herrero 1995). Approximately 25 grizzly bears per year have active radio‑collars. These bears are monitored from air and ground wherever they go and our budget permits. Aerial
monitoring gives infrequent, but relatively unbiased data regarding location. This facilitates understanding of home range, movements and habitat use. Ground‑based research allows intensive monitoring of grizzly bear activities related to development features such as towns, highways, campgrounds and trails. Mortality is monitored using both aerial and ground‑based telemetry. The radio‑telemetry monitoring area includes lands under several different jurisdictions. In the British Columbia portion of these lands, where some of our radio‑collared grizzly bears are found, there is the Columbia Mountains Bear Research Project which provides complementary data and will allow a broader ecosystem versus provincial boundary‑based understanding of grizzly bears in the Central Rockies Ecosystem.

CAPTURE

A concerted effort to deploy GPS radio collars in Canmore and the Lake Louise areas was the only planned trapping in 2001. Three additional grizzly bears were captured during management actions (Table 1).

TELEMETRY DATA SET

Aerial and ground monitoring from early April until the first week of November produced 2456 point locations for the 2001 field season. Of these 341 (14 %) were from the air and 2115 (86%) from ground monitoring. Aerial locations were biased toward early morning hours. Ground locations were biased towards where observers could travel easily.

Since the project began in May 1994 a total of 65 individuals have been handled (Table 2). Of those, 17 have died, and 23 are currently radio collared. The sex/age breakdown of the current radio collared sample is as follows:

14 adult females 5 adult males

2 subadult females 2 subadult male

POPULATION DEMOGRAPHICS

Observations from the research team as well as records from Banff National Park and Alberta Natural Resources Service established a minimum unduplicated count of females with cubs for the year (Table 3). Over time, a minimum count of sows with cubs (Table 4) can be established and used as a trend indicator (Knight et al. 1995).

Reproductive success of radio collared females was determined through year to year visual observations between 1994 and 2001 (Table 5). Year to year cub survivorship can be tracked by referring to the table and comparing the number of cubs observed in a given year to the previous years observations. Reproductive data from collared females is being be used to construct an estimate of whether the sample population is increasing or decreasing.

There were 4 known mortalities within the study area in 2001 (Table 6). An unmarked subadult female was shot after a livestock depredation in May. Subadult male #67 was hit by a vehicle on the Trans Canada Highway in May. Adult female #56 was hit by a train near Lake Louise in September. An unmarked subadult female was shot in self defense over a hunter kill in Kananaskis Country in September.

There were 2 grizzly bear translocations out of the study area in 2001. Research bears # 68 and 69 were removed after frequent sightings and encounters along the outskirts of Canmore. Since 1993, there have been 9 translocations from the Bow River Watershed (Table 7).

The 40 grizzly bear deaths and removals in the Bow River Watershed between 1994 – 2001 are from a number of causes (Table 8). No one factor stands out. The diversity of mortality and removal causes means that it will continue to be challenging to maintain acceptable mortality / removal rates for subadult and adult female bears.
