Colorado Unit 1 Pronghorn Antelope Hunting Guide

Unit 1 sits in the northwest corner of Colorado's pronghorn country, a limited-quota unit covering 81,261 acres with elevations ranging from 5,008 to 8,858 feet. For hunters researching this specific unit, there's one point that needs to be made immediately and clearly: every pronghorn hunt in Unit 1 is a draw hunt. There is no general season here, and no over-the-counter fallback. If hunters want to chase pronghorn in Unit 1, they're applying for a limited-quota tag and waiting on the results.

That structure matters because it shapes everything downstream — how competitive the unit is, how it fits into a long-term points strategy, and what kind of experience hunters can expect once they're in the field. With 92% of the unit in public hands, access is not the limiting factor here that it is in many Colorado pronghorn units where private land dominates the landscape. The limiting factor is simply getting drawn.

This article breaks down what the data shows about Unit 1 — recent harvest trends, herd composition, trophy potential, and how the application process works — so hunters can decide whether this unit deserves a spot in their points strategy.

HuntPilot Analysis: Is Unit 1 Worth Applying For?

Based on the data available through HuntPilot, Unit 1 presents a mixed but generally favorable picture for pronghorn hunters willing to invest points.

The most encouraging signal is the 2025 harvest data: 108 hunters afield with 73 animals harvested, a 68% success rate. That's a strong number for pronghorn, and it suggests that whatever limitations existed in prior years, hunters drawing tags in 2025 found huntable animals and had a productive season. Compare that to 2020, when only 18 hunters pursued pronghorn in the unit and just 4 connected — a 22% success rate. That's a significant swing, and it's worth noting before assuming Unit 1 is a guaranteed high-success unit every year. Hunter numbers also varied substantially across the sampled years — 14 hunters in 2024, just 4 in 2022, and 22 in 2019 — which tells us tag allocations have fluctuated considerably, likely in response to herd conditions.

The wildlife survey data adds useful context. Across six survey years from 2018 to 2024, the average buck:doe ratio sat at 42:100. That's a solid, biologically plausible ratio for pronghorn — not spectacular, but consistent with a healthy, well-structured herd that isn't being over-harvested on the buck side. It doesn't scream "trophy factory," but it does suggest a stable population base to draw from.

On trophy potential, the counties overlapping Unit 1 carry a strong history of trophy-class record-book entries. That history is shared across neighboring units whose boundaries fall within the same counties, so it shouldn't be read as proof that record-class bucks are concentrated exclusively in Unit 1. But it does indicate that this general area of northwest Colorado has consistently produced quality pronghorn over time, which is a meaningfully positive data point for hunters weighing where to spend hard-earned points.

Put together: Unit 1 is worth applying for if a hunter has banked enough points to be competitive, is comfortable with some year-to-year variability in harvest success, and values a public-land-heavy unit in a county with a track record of trophy production. It's not a unit to chase on a whim with zero points — the draw-only structure and the trophy-area reputation both suggest sustained demand.

Harvest Success Rates

The harvest numbers for Unit 1 tell a story of variability rather than consistency, which hunters should factor into their expectations.

• 2025: 108 hunters, 73 harvested — 68% success
• 2024: 14 hunters (harvest/success rate not available)
• 2022: 4 hunters (harvest/success rate not available)
• 2020: 18 hunters, 4 harvested — 22% success
• 2019: 22 hunters (harvest/success rate not available)

The gap between 2020's 22% success and 2025's 68% success is substantial. Several factors could explain a swing like this — herd recovery following a tough winter, changes in tag quotas relative to animal density, or simply a stronger fawn-crop year translating into more visible, huntable bucks. Without additional data bridging those years, it's not possible to say definitively what drove the improvement, but the trend by itself is a positive sign for hunters drawing tags in recent cycles. Hunters should treat the 68% figure from 2025 as the most current indicator of on-the-ground conditions, while keeping in mind that pronghorn populations in northwest Colorado have been affected by severe winter weather events in the broader region in past years — a reminder that herd conditions can shift from one season to the next.

Trophy Quality

Trophy data for the counties overlapping Unit 1 points to a strong history of record-book production. This is a meaningful positive for hunters who care about buck quality and not just opportunity, but it comes with an important caveat: record-book entries are logged by county, not by hunt unit, and the counties overlapping Unit 1 also overlap neighboring units. That means the trophy history reflects the broader area rather than being unit-exclusive.

That said, a strong county-level trophy history combined with a healthy buck:doe ratio averaging 42:100 is a reasonable basis for optimism. It suggests the habitat and herd management in this part of the state have been conducive to producing mature bucks over time, even if any single hunter's chances of tagging a record-class animal in a given season remain low, as they do in virtually every pronghorn unit in the West.

Herd Health & Population Trends

The survey data available for Unit 1 covers six years between 2018 and 2024, with an average buck:doe ratio of 42:100. This is a reasonable, biologically sound ratio for a pronghorn herd — it indicates bucks are surviving to maturity in sufficient numbers without any red flags suggesting a heavily skewed or over-hunted population.

Unfortunately, year-by-year breakdowns within that six-year window aren't available in the data provided, so it's not possible to say whether the ratio has been trending up, down, or holding steady across those specific years. The average itself, however, is a useful baseline: a 42:100 ratio sits comfortably within the range considered healthy for managed pronghorn herds, and it lines up with the harvest data showing improved success rates in the most recent harvest year on record.

Access & Terrain

Unit 1 is overwhelmingly public land — 92% of the unit's 81,261 acres are publicly accessible, which is a significant advantage for DIY hunters in a species that, in many parts of Colorado, is hemmed in by private ranchland controlling the best water and forage. There's no wilderness designation within the unit, meaning hunters can access the terrain with standard vehicle and foot travel without the added restrictions that come with wilderness boundaries.

Elevation within the unit ranges from 5,008 feet up to 8,858 feet, which covers a wide band of terrain — from lower sagebrush flats and basin country typical of pronghorn range up into higher foothill terrain. This elevational spread gives hunters some flexibility to glass different habitat types depending on where pronghorn are concentrated during the season, and it's consistent with the kind of open, rolling sagebrush country pronghorn prefer across northwest Colorado. Hunters can use HuntPilot's mapping tools to review public land boundaries and plan specific glassing locations within the unit based on terrain and water availability.

How to Apply

Colorado uses a preference-point system for pronghorn, and because Unit 1 has no general season, every hunter pursuing pronghorn here must apply through the draw — there is no over-the-counter alternative for this unit.

For residents, Colorado's draw structure is true preference: the highest point holders in the applicant pool draw first, which means that if hunters accumulate enough points, a tag becomes effectively guaranteed in a given unit, rather than functioning as a weighted lottery. Nonresidents apply through a separate pool from residents, and because Colorado caps nonresident tag allocations, nonresident point requirements for competitive units like Unit 1 tend to run higher than resident requirements for the same unit.

Key structural points for hunters considering Unit 1:

• No general season exists — this is a 100% limited-quota draw unit for pronghorn.
• Residents and nonresidents apply through separate pools, with different point thresholds required for a competitive application.
• Points are not spent incrementally — a successful draw consumes accumulated points, and hunters restart their point total after drawing a tag.
• Leftover or secondary draw opportunities may exist after the primary draw, depending on how many tags go unclaimed — hunters should check Colorado Parks and Wildlife's published leftover list timing each year.

Because draw odds, tag quotas, and application details change every cycle, this article won't cite specific numbers that will go stale. For current application windows, fees, and draw odds broken down by resident/nonresident status and point level, see HuntPilot's Colorado state page.

Frequently Asked Questions

Is Unit 1 a good unit to apply for pronghorn in Colorado? Based on available data, Unit 1 shows a strong 2025 harvest success rate of 68%, a healthy average buck:doe ratio of 42:100 across recent survey years, and county-level trophy history that points to a consistent track record of quality bucks in the broader area. For hunters with enough points to be competitive, it's a reasonably strong option. The unit's lack of any general season means hunters must commit to the draw-only process, so it's best suited to those already building points for Colorado pronghorn rather than hunters looking for a last-minute opportunity.

What is harvest success like in Unit 1? Harvest success has varied significantly across recent years, from a low of 22% in 2020 to 68% in 2025. Hunter numbers in the unit have also fluctuated, ranging from just 4 hunters in 2022 up to 108 in 2025. The most recent data point is the strongest, but hunters should understand that success rates in this unit are not static year to year.

How big are the pronghorn in Unit 1? The counties overlapping Unit 1 have a strong history of producing trophy-class record-book pronghorn, though that trophy history is shared across neighboring units within the same counties rather than being exclusive to Unit 1. Combined with a healthy buck:doe ratio, this suggests the area supports mature bucks reasonably well, though specific scores and entry counts aren't available for public citation here.

What is the terrain like in Unit 1? Unit 1 spans elevations from 5,008 to 8,858 feet across 81,261 acres, with 92% of the land base in public ownership and no wilderness designation. This combination of high public access and open elevation range gives hunters flexibility to scout and glass across varied sagebrush and foothill terrain without the access restrictions that limit many other Colorado pronghorn units dominated by private ranchland.

Can nonresidents hunt pronghorn in Unit 1 without a guide? Yes. Colorado does not require nonresidents to hire a guide or outfitter for pronghorn hunting, including in Unit 1, since the unit carries no wilderness designation. Nonresidents can hunt the unit DIY once they've drawn a tag, taking full advantage of the 92% public land base.
