Broomfield has temporarily closed several trails at The Field Open Space because of aggressive coyotes.

Broomfield closed several trails at The Field on Tuesday because of reports of coyotes coming close to on-leash dogs. The coyotes have bared their teeth or displayed other aggressive behavior.

There have been no reports so far of pets or people who have been harmed, said Open Space and Trails coordinator Kristan Pritz.

Pritz said it is likely that the coyotes are territorial because they have just had pups. Coyotes are sometimes more territorial when they have young to care for, she said.

Open Space and Trails will assess the area on a weekly basis to determine when it will be appropriate to re-open the trails, she said.

Broomfield has been carrying out hazing techniques in order to scare coyotes away, but will only haze coyotes who seem aggressive, not coyotes who appear to be nursing or taking care of pups, Pritz said.

Broomfield and Colorado Parks and Wildlife are expected to have a meeting to talk about the coyotes in the next day or so, she said.
