Wolf rendezvous sites

Adult wolves are very defensive of pups at rendezvous sites and will attack other predators, including dogs, that get too close to the rendezvous site or the pups. Wolves are probably most aggressive toward strange wolves and dogs at den and rendezvous sites when their pups are small, during the breeding season in January and February and when they are protecting a fresh kill.

Found within a wolf pack's territory, den and rendezvous sites are specific locations used for breeding and other pack activities. Wolves begin moving their young pups from dens to rendezvous sites from mid-March to mid-May. Rendezvous sites are actively used from mid-May to mid-October.

Habitat: Rendezvous sites are generally open areas of grass or sedge adjacent to wetlands, and can be determined by the high presence of both large and small wolf tracks. Sites are characterized by extensive matted vegetation, numerous trails and beds usually at the forest edge. They are often adjacent to bogs or occur in semi-open stands of mixed conifer-hardwoods adjacent to swamps. Sometimes abandoned beaver ponds are used as rendezvous sites.

Description: Rendezvous sites are the home sites or activity sites used by wolves after the denning period, and prior to the nomadic hunting period of fall and winter. Pups are brought to rendezvous sites from dens when they are weaned, and remain at rendezvous sites until they are old enough to join the pack on their hunting circuits. Rendezvous sites may be associated with food sources such as ungulate kills or berry patches. Generally a series of rendezvous sites are used by a specific pack. Rendezvous sites are mostly used from mid-June to late-September, but use may start as early as mid-May and can continue to early or mid-October. Some intermittent use of rendezvous sites may continue into the fall. It appears that an average of four to six rendezvous sites are used by wolf packs.
