November 5-8: Rights of Nature Film Festival schedule and information

Watch a fascinating introduction to the film festival!

North area TSA City of Boulder

The City of Boulder Open Space and Mountain Parks Department is developing plans for management of the 7,700 acres of OSMP-managed lands north of Linden Avenue and the Diagonal, and they are soliciting input from all interested people. It is critical that people stand up for habitat conservation and wildlife at these meetings. More information is on the City of Boulder website.

You can still comment on the proposed plan.

BCNA Board Meeting

The next BCNA board meeting will be November 8th at 3 pm at City of Boulder Open Space building on Cherryvale. All are welcome to attend.
