A Small Fish with a Big Job: The Return of the Common Shiner

For the first time in 40 years, a rare native fish is swimming in the Poudre River near Fort Collins again. The Common Shiner, currently found in only three streams statewide, disappeared from our stretch of the river in the mid-1980s. In July, Colorado Parks and Wildlife (CPW) released 4,000 shiners into several sites near town, including your Natural Areas. The fish were raised at the J.W. Mumma Native Aquatic Species Restoration Facility in Alamosa, Colorado, and the release marked the first reintroduction effort into the Poudre River since their disappearance four decades ago.

This effort traces back to the 2020 Cameron Peak Fire. In 2021, heavy rain over the burn scar sent large amounts of fine sediment into the river and resulted in a widespread fish kill. The event reduced trout populations, and while trout have rebounded in canyon reaches, some reaches near Fort Collins have continued to show persistent reductions. This presented an opportunity to study whether such alterations to the fish community may allow for lost native fish species, like the Common Shiner, to return. A joint effort between the Colorado State University Larval Fish Laboratory and CPW will monitor the fish community into the future, building upon years of existing data, to track the results of this effort.

Although it’s a small fish, the Common Shiner has a big job: helping show what recovery might look like after wildfire, not just here, but in river basins across the West.

Celebrate National Trails Day

Give back to your public lands on Saturday, Sept. 26 at Reservoir Ridge Natural Area!

Sow it Forward: Seed Swap Season

Do you have a native garden at home bursting with flowers and seeds? The NoCo Native Seed Swap is a free community event that gives away native seeds and we need seeds from your gardens! Due to the severe drought this year, there are fewer seeds in the landscape for our volunteers to collect, clean and give away. By collecting and donating from your garden, you can share beauty and bounty with the community while helping native pollinators and other wildlife thrive. Seeds should be dried, free of pesticides and herbicides and labeled with their Scientific Name, your name, location and year of collection. Please drop off your seeds with us by Nov. 1 (or earlier) and we can clean them at one of our community seed cleaning events.

To donate seeds or for questions, contact the NoCo Native Seed Swap coordinator at annemarie@wrv.org or krentschlar@fortcollins.gov

Timber Trail Improvements Continue This Fall

The Timber Trail in Pineridge Natural Area is entering Phase 2 of its maintenance project to improve safety, sustainability and access for all users, with work planned late September through mid-October 2026. The trail will remain open throughout construction.

During Phase 1, Natural Areas staff, with help from dedicated volunteers, rebuilt three boardwalks, installed 50 drainage features, completed two minor trail alignments and improved 2,400ft of trail tread. Phase 2 will focus on a major realignment of the northern portion of the Timber Trail and will include 2,760ft of new trail tread, restoration of 1,390ft of degraded trail, additional tread and rock work, and restoration and revegetation of old trail segments.

The new alignment will improve trail connectivity, allowing users of all types to connect back to the Dixon Reservoir Loop trail and providing hikers with direct access to the upper parking area at Pineridge Natural Area, helping maintain a consistent trail experience while integrating progressive technical trail features to support a diverse range of ability levels.

The project has included coordination with trail user groups and staff review of cultural resources, wildlife and botany to balance recreation needs with long-term trail sustainability.
