For the first time since they were reintroduced to the state in December, Colorado gray wolves have moved out of central Grand County, state wildlife officials said in their July report.
In July, the eleven wolves and one pup stayed relatively in the same watersheds as in May and June, traveling between Routt, Jackson, Larimer, Grand, Eagle and Summit counties. a new location map released Tuesday by Colorado Parks and Wildlife.
CPW releases a map every month showing which watersheds the state’s collared wolves have traveled, conservationists said. A wolf may or may not remain there, and it may not have crossed every part of that watershed.
The updated map shows wolf activity from June 25 through July 23 in watersheds from the Wyoming border to Interstate 70 and from west of Craig in Moffat County to west of Fort Collins in Larimer County.
While the monthly maps from December to June show wolves using watersheds in Grand County up to the Boulder County border, the July map shows a lack of data in the area, indicating that wolves do not use the area at all in July visited.
The collars record a GPS position every four hours and send the data to state biologists once four locations are recorded, CPW officials said. State officials do not share specific locations to protect wolves and may “buffer” maps to protect wolves during certain times of the year, such as mating season.
Although the July map highlighted watersheds south of Interstate 70, CPW officials said no wolves had crossed the major highway and the population was exploring land to the north.
State officials released nine of 11 adult wolves roaming northern Colorado in December as part of a voter-mandated reintroduction plan.
Since then, CPW officials said two of the wolves have mated and had at least one pup, and a few wolves from Wyoming have naturally migrated to the state and joined the Colorado pack.
Two of 10 collars placed on wolves in December no longer worked, but those two wolves are still alive and traveling with other wolves with functioning collars, state officials said in April. There are currently no plans to re-capture the wolves or place collars on the pups.
The map’s accuracy will decrease over time as wolves enter Colorado from other states, collars stop working and more wolves mate and give birth to pups, state conservation officials said. The goal is to keep at least two collared wolves in each pack.
