Pitkin commissioners advance Northstar Nature Preserve plan after unanimous advisory board recommendation

Pitkin County’s Board of County Commissioners heard a detailed presentation on March 11 about an updated management plan designed to guide stewardship of the Northstar Nature Preserve east of Aspen.

Open Space & Trails Director Gary Tenebalam said the draft reflects roughly a year of public outreach and more than 1,000 “touch points” with stakeholders, plus 26 independent ecological reports and a formal visitor‑use study. The update frames Northstar as a nature preserve and defines conservation values, desired conditions, 42 actions and 39 monitoring indicators that staff will track against thresholds to trigger adaptive management responses.

Consultants who helped design the visitor‑use study — Steve Lawson and Chris Mons — told the board the plan uses an internationally recognized, indicator‑based approach to set user capacities and response options. Both experts, who have worked on river and national park visitor‑use programs nationwide, said the plan is data‑driven and is comparable in rigor to similar efforts in major parks.

The plan lays out a spectrum of response options, ranging from low‑tech education and voluntary closures to more direct tools, such as parking management, seasonal closures and a possible river‑use permitting program if jurisdictional changes (a proposed Wildwood land exchange) occur. Commissioners and experts discussed how the plan would handle surges in visitation and the conditions that could trigger more restrictive measures.

Open Space & Trails staff emphasized that most of the plan’s proposed actions (about 69 percent) are focused on ecological protection and restoration. The plan also sets a voluntary group‑size cap of six people per party and describes outreach measures for river users and commercial outfitters.

Board members asked about enforcement and commercial outfitter permits; staff and rangers said a recent cap on commercial operators (five permits) has improved oversight and relationships with outfitters, who must follow training and rules. Staff also said monitoring to date shows most ecological indicators are stable or improving, and the plan codifies monitoring and response options to preserve habitat.

Commissioners did not vote to adopt the plan on March 11 but moved the measure forward: the board set the updated Northstar Nature Preserve Management Plan for second reading and public hearing on March 25. If adopted, the plan will provide a formal, monitored framework that staff said will allow Pitkin County to respond to visitor pressure while prioritizing ecological values.
