We studied 2 years of postrelease telemetry data of elk (Cervus elaphus) translocated to their historic range limit in Ontario, Canada and sought to determine if postrelease movements were related to behavior, demography of released animals, or site-specific attributes such as length of holding period. During 1998-2004 we radiotracked 341 elk in 10 release groups via ground and aerial telemetry and monitored movement patterns relative to gender, age, and pre-release holding period (4-112 days). We found that elk that were held for short periods prior to release (4-11 days) moved longer distances than those subject to extended conditioning (17-112 days), suggesting that an extended conditioning period is beneficial from the standpoint of promoting philopatry. When all elk were pooled by sex and age class, male calves remained in closer proximity (8.0 ± 13.2 km) to release sites than adult females (19.1 ± 20.6 km), adult males (19.7 ± 15.1 km), and female calves (14.4 ± 20.4 km). Most calves dispersed in a southeasterly direction whereas adults tended to travel southwest. Our results reveal that elk movement characteristics are influenced by factors such as release protocol and group demographics; these findings provide further insight regarding appropriate release methods for restoring natural populations near their historical range limit.

The 13th North American Caribou Workshop which was held in Winnipeg, Manitoba, was a great success with more than 400 participants: people from Canada, the United States, Norway and Greenland, representatives from co-management and resource management boards across North America, First Nations, Inuit and Inuvialuit, governmental and non-governmental organisations, private companies, researchers, students and youth. The theme of the Workshop was Sustaining Caribou and their Landscapes – Knowledge to Action and the intent of the organizers was twofold: first, to provide participants with the opportunity to share scientific and traditional knowledge on different subspecies and ecotypes of Rangifer across the circumpolar North, the particularities of the different landscapes and land use management issues; second, to explore innovative ways to transfer knowledge to action, ensuring the long-term persistence of Rangifer throughout its range through the development of better governance structures, sound policies and effective communication
