In view is the North Sky Trail crossing the south bridge and continuing on a 19th century railroad grade into the North Foothills Habitat Conservation Area (HCA).
The HCA is home to Bell's twinpod - a rare, globally imperiled plant that grows on barren shale patches...and in the entire world, only in Boulder and Larimer counties!
Staying on designated trails in this area helps OSMP ensure this fragile ecosystem remains stable and healthy so Bell's twinpod can survive and thrive in a world with ever increasing pressure on the land.
The Open Space and Mountain Parks Department preserves and protects the natural environment and land resources that characterize Boulder. We foster appreciation and use that sustain the natural values of the land for current and future generations.
