Boulder County Parks & Open Space has implemented a temporary wildlife closure in an area near the Tucker Property and Cardinal Mill in Nederland.

The closure is in place through September 15 to protect sensitive wildlife. Boulder County is asking all visitors to respect closure signs and avoid the affected area while the closure is in effect.

At this time, BMA has not received a detailed map of the closure area and is awaiting additional information from Boulder County. We will share updates with the community as they become available.

We know this area is popular with outdoor recreationists. This closure is temporary and is intended to provide wildlife the space needed during a sensitive time of year.

We will provide additional information as Boulder County releases more details about the affected area. For questions about this closure, email [email protected]

“Levy also cautioned against reading too much into the survey results.

"This is not a scientific survey. It is not representative in any way of actual broad public sentiment. The hikers generally aren't organized the way the bikers are," Levy said.”

Denver7's Boulder County reporter Colin Riley found that of the 7,522 people who responded to the county's public feedback survey, about 70% either "opposed" or "strongly opposed" the idea. More on this development ⬇️

"We hope the County understands that many of the people being discussed here are not thrill-seeking outsiders passing through. We are local families trying to stay healthy, connected and present in our community while sharing these lands respectfully with others. Whatever the County ultimately decides, we hope this human perspective is part of the picture."

Boulder Reporting Lab obtained Boulder County’s Alternating Trail Use Pilot survey data, here’s what they found:

https://boulderreportinglab.org/2026/06/04/boulder-county-survey-finds-strong-opposition-to-trail-use-pilot-that-could-limit-bike-access/

A survey of more than 7,500 people found strong opposition to a proposed pilot that would limit trail access for some users. Support was strongest among older hikers, while mountain bikers made up the largest share of respondents.
