Colorado Unit 107 Pronghorn Antelope Hunting Guide

Colorado Unit 107 is a limited-quota pronghorn hunting unit located on the state's eastern plains, with elevations ranging from 4,394 to 5,766 feet across a total area of 794,379 acres. Every hunt in this unit is drawn — there is no general season here, so hunters need to understand the draw process from day one, not just as an afterthought. For hunters researching Unit 107 specifically, the most important number to internalize before anything else is the public land figure: just 3% of this unit is publicly accessible.

That single statistic shapes nearly everything about how this unit should be approached. With harvest data showing success rates that have ranged from 47% to 76% over the past five years, Unit 107 clearly produces pronghorn for hunters who draw tags — but how those hunters get access to huntable ground is the real story here, and it's a story dominated by private land.

This article breaks down what the data actually says about Unit 107 — harvest trends, herd composition, trophy potential, and the practical realities of hunting a unit where public ground is scarce — so hunters can decide whether to spend points here or look elsewhere.

HuntPilot Analysis: Is Unit 107 Worth Applying For?

The harvest numbers for Unit 107 tell a story of solid, consistent success for hunters who draw a tag. Looking at the five most recent years of data:

• 2025: 984 hunters, 462 harvested, 47% success
• 2024: 641 hunters, 422 harvested, 66% success
• 2023: 584 hunters, 360 harvested, 62% success
• 2022: 479 hunters, 366 harvested, 76% success
• 2021: 492 hunters, 308 harvested, 63% success

Four of the last five years show success rates in the 62-76% range, which is respectable for pronghorn hunting anywhere in the West. The 2025 season's drop to 47% success, paired with a significant jump in hunter numbers (984 versus 641 the year before), is worth noting — a larger hunter pool combined with a lower success rate suggests either more tags were issued, pressure increased on available animals, or conditions were tougher that year. Hunters should watch whether 2025 was an outlier or the start of a trend as more recent data becomes available.

The bigger issue for anyone considering Unit 107 is access. With only 3% of the unit classified as public land, the overwhelming majority of the 794,379 acres here is private property. This is not a unit where a hunter can pull up a public land layer, find a chunk of accessible ground, and start glassing. The vast majority of huntable terrain requires either a private land arrangement, landowner permission, or a guided/outfitted hunt on leased ground. This aligns with what's reflected in eastern Colorado pronghorn hunting broadly — public access is the exception, not the rule, and hunters without a private land connection need to plan for that reality well before they draw a tag.

The herd composition data adds another layer of complexity. Survey data collected across six years (2018-2024) shows an average buck:doe ratio of just 20:100. That is a low ratio for pronghorn, well below what would indicate a herd skewed toward mature bucks or light hunting pressure on males. A 20:100 ratio suggests a herd structure where does significantly outnumber bucks, which can mean more hunting pressure relative to the buck population, a herd that's been managed for higher off-take, or natural demographic factors specific to this unit. Whatever the cause, hunters should temper trophy expectations accordingly and understand this is more a herd defined by opportunity than by mature buck density.

Bottom line: Unit 107 is worth applying for if a hunter already has private land access lined up, is planning to hunt with an outfitter who holds leases in the unit, or has family/personal connections to landowners in the area. For a hunter without any of those things, the 3% public land figure is a serious limiting factor that should not be glossed over. Success rates look good on paper, but those numbers are being driven substantially by hunters who aren't fighting for scraps of public ground — they have somewhere solid to hunt.

Trophy Quality

Trophy history for the counties overlapping Unit 107 shows a moderate track record of producing record-book-caliber pronghorn. This isn't an area with an extensive or standout trophy pedigree, but it isn't devoid of history either — some quality bucks have come from this general area over time. Given that record-book entries are logged at the county level rather than by specific hunt unit, any trophy production attributed to this region is shared with neighboring units that overlap the same counties, and hunters should not assume Unit 107 alone is responsible for that history.

Combined with the below-average buck:doe ratio from recent survey data, hunters should set realistic expectations: Unit 107 is more likely to produce a solid, mature representative buck than a genuine trophy-class animal in any given year. Hunters chasing a wall-hanger above and beyond a good hunting experience should weigh this moderate trophy history against units with a more consistent or pronounced trophy record before committing points here.

Herd Health & Population Trends

The six-year survey window (2018-2024) for Unit 107 shows an average buck:doe ratio of 20:100. This is a notably low ratio compared to healthy pronghorn herds across the West, where ratios in the 30-50:100 range are more commonly associated with balanced age structure and better buck availability. A ratio this low suggests one or more of the following: consistent hunting pressure on bucks, doe-heavy population management objectives, or herd dynamics specific to the habitat and land use patterns in this part of the state.

For hunters, the practical takeaway is that Unit 107 functions more as a numbers unit than a quality unit. Harvest success has stayed reasonably strong across multiple years, which tells us there are huntable pronghorn out there for tag holders — but the demographic data doesn't point toward an unusually mature or lightly-pressured buck population. Hunters should go into this unit expecting a fair, representative pronghorn hunt rather than banking on a standout buck based on herd health metrics alone.

Access & Terrain

Unit 107 sits at relatively low elevation for Colorado, ranging from 4,394 to 5,766 feet, which is consistent with the high plains terrain typical of eastern Colorado pronghorn country — open, rolling grassland and sagebrush flats without the elevation gain or timber found in the state's mountain units. There is no wilderness acreage in this unit, so wilderness access rules and guide requirements simply don't apply here.

The critical access number, though, is the 3% public land figure across the unit's 794,379 total acres. This means the vast majority of huntable ground — well over 770,000 acres — is privately held. For a DIY hunter without a private land connection, this unit presents a genuine access challenge. Options for hunters in this position generally include:

• Securing written permission from private landowners in advance of the season
• Booking a guided hunt with an outfitter holding leases or access agreements within the unit
• Identifying and thoroughly scouting the limited public parcels that do exist, understanding that competition for those parcels will be high given how little public ground is available

Hunters should not assume they'll find open, huntable public ground simply by showing up with a tag in hand. Given how little of Unit 107 is public, doing this legwork — calling landowners, researching lease options, or lining up a guide — needs to happen well before the season, not after the draw results come out. HuntPilot's data on this unit reinforces that access planning, not just draw strategy, is the make-or-break factor for a successful hunt here.

How to Apply

Because Unit 107 has no general season, every pronghorn hunt here is issued through Colorado's limited-quota draw system. This applies to antlered and either-sex hunts alike — there is no over-the-counter fallback option for hunters who miss out in the draw. Anyone wanting to hunt pronghorn in this unit must apply.

Colorado's draw system for pronghorn is a preference-point-based structure. In simple terms, hunters who apply and don't draw a tag accumulate a preference point, and higher point totals improve standing in the draw over time. Colorado uses a true preference system for a portion of its tags — meaning hunters with the highest point totals are awarded tags first — which is different from a pure weighted lottery. A high enough point total can position a hunter to draw a specific hunt code, though how many points are actually needed shifts from year to year based on how many hunters apply and how many tags are issued.

Residency matters significantly in Colorado's draw. Resident and nonresident applicants are typically evaluated in ways that affect overall competitiveness, and nonresidents should expect this unit — like most limited-quota Colorado pronghorn units — to require patience and point-building before becoming realistic.

Given the extremely low public land percentage in Unit 107, hunters should also factor private land access into their application strategy. Drawing a tag here without a plan for where to actually hunt is a common mistake — start working on landowner permission or outfitter arrangements at the same time as (or before) applying.

Application dates, fees, and current draw odds change every cycle. For up-to-date deadlines, license costs, and draw odds specific to Unit 107, see HuntPilot's Colorado state page at /states/CO.

Frequently Asked Questions

What is the terrain like in Colorado Unit 107? Unit 107 sits at relatively low elevation for Colorado, between 4,394 and 5,766 feet, characteristic of the state's eastern plains. This is open grassland and high plains country typical of pronghorn range — flat to rolling terrain without significant elevation change or timber cover. There is no wilderness acreage within the unit.

What is harvest success like in Unit 107? Harvest success has generally been strong over the past five years, ranging from a low of 47% in 2025 to a high of 76% in 2022. The years 2021 through 2024 all posted success rates between 62% and 76%, indicating that hunters who draw tags and secure access to huntable ground have a reasonably good chance of filling their tag. The 2025 season saw a notable increase in hunter numbers alongside a drop in success rate, which is worth monitoring in future data.

How big are the pronghorn in Unit 107? Trophy history for the counties overlapping this unit shows a moderate track record, with some quality bucks taken historically but no standout trophy reputation. Combined with a below-average buck:doe ratio (averaging 20:100 across six survey years from 2018-2024), hunters should expect a fair chance at a mature, representative buck rather than betting on genuine trophy potential.

Is Unit 107 worth applying for? It depends heavily on access. The unit is just 3% public land, meaning the vast majority of the 794,379 total acres is privately owned. Hunters with private land access, landowner connections, or a guided hunt lined up will find solid, consistent harvest success based on recent data. Hunters without any of those things should think carefully before spending points here, since drawing a tag with nowhere to hunt is a real risk in a unit this dominated by private ground.

Do I need a guide to hunt pronghorn in Unit 107? Colorado does not have a state-mandated guide requirement tied to wilderness access (and this unit has no wilderness acreage regardless). However, given that only 3% of the unit is public land, many hunters without existing private land access choose to hire an outfitter with lease agreements or landowner relationships simply to have a place to hunt — not because the state requires it, but because of the practical access situation on the ground.
