Wyoming Unit 91 Pronghorn Antelope Hunting Guide

Wyoming Unit 91 has built a reputation among nonresident pronghorn hunters as a unit worth the wait, and the numbers back it up. With 440,855 total acres, 93% public land, and a limited-quota draw structure that keeps hunter numbers in check, Unit 91 offers exactly the kind of public-land opportunity that draws hunters to Wyoming's pronghorn program in the first place. This is not a unit where hunters show up on a whim — every hunt here is limited-quota, meaning access is controlled entirely through the draw, and that scarcity is part of what makes the hunting good.

This article breaks down what the data actually shows for Unit 91: harvest performance, tag trends, herd composition, and the practical realities of applying, all sourced from HuntPilot's unit-level data. The goal is a clear-eyed read on whether this unit deserves a spot on a hunter's application list.

Hunt Structure: A Limited-Quota Unit Only

Unit 91 does not offer a general season for pronghorn. Every hunt available here — including hunts for antlered/either-sex animals — is limited-quota and allocated through Wyoming's draw system. There is no walk-in, buy-an-OTC-tag option in this unit. Hunters who want to hunt Unit 91 must apply and draw, whether they're after a buck or an either-sex tag. This matters for planning purposes: hunters can't fall back on a leftover or general license here if they miss the draw, so the application itself is the whole game.

Harvest Success Rates

Unit 91's harvest numbers are strong across the board, and they've been trending in an interesting direction. In the 2025 season, 135 hunters harvested 127 animals for a 94% success rate — some of the best numbers in the recent data set. That follows a similarly strong 2024, when 75 hunters harvested 70 animals for a 93% success rate. Going back further, 2023 posted 66 hunters and 57 harvested animals for an 86% success rate, and 2022 saw a much larger draw of 429 hunters with 377 harvested for an 88% success rate.

Two things stand out here. First, success rates have consistently sat in the mid-to-high 80s and low-to-mid 90s across four seasons — this is a unit where drawn hunters overwhelmingly fill their tags. Second, the hunter numbers themselves have shifted dramatically, dropping from 429 hunters in 2022 to just 66-135 hunters in the following three seasons. That's a meaningful reduction in hunting pressure, which likely contributes to the rising success percentages seen in 2024 and 2025. Whatever is driving that quota tightening, the practical effect for a hunter who draws a tag in Unit 91 is a very high likelihood of putting an animal on the ground.

Trophy Quality

The counties overlapping Unit 91 carry a strong history of trophy pronghorn production. That means hunters drawing tags here are hunting in an area with a real trophy pedigree, not just a numbers unit. It's worth noting that record-book entries are attributed at the county level, not the unit level, so that trophy history is shared with neighboring units whose boundaries fall in the same counties — the animals credited to those records could have come from anywhere across that broader area. Still, a strong county-level trophy history is a meaningful signal: this is genetic and habitat country capable of producing mature, well-developed bucks, not just a place to fill a tag.

Combined with the high harvest success rates, Unit 91 looks like a unit where hunters aren't just tagging out — they're doing so in country known for quality animals.

Herd Health & Population Trends

Wildlife survey data collected across four survey years (2021-2024) shows an average buck:doe ratio of 55:100 for Unit 91. That's a healthy ratio by pronghorn standards — well above the roughly 40:100 threshold that typically signals a herd with good buck representation and reasonable age structure in the population. A 55:100 average across four full survey years (rather than a single anomalous reading) suggests this is a genuine, sustained trend rather than a statistical fluke, and it lines up with the strong trophy history and high harvest success discussed above. Hunters can reasonably expect a herd with solid buck numbers relative to does, which supports both opportunity and the potential to be selective for a mature animal.

Access & Terrain

Unit 91 spans a wide elevation range, from 6,576 feet up to 13,069 feet, within its 440,855 total acres. That's an unusually broad elevation spread for a pronghorn unit, and it points to varied terrain — from lower sagebrush flats and basins typical of pronghorn range up into much higher country at the unit's margins. Most pronghorn hunting activity will concentrate in the lower-to-mid elevation sagebrush and grassland habitat that this species prefers, but hunters should be aware the unit isn't uniformly flat, open rangeland from end to end.

Public land dominates the unit at 93%, which is outstanding for DIY access. With the vast majority of the acreage open to public hunting, hunters drawing a tag here should have ample room to spread out, glass, and work terrain without needing to negotiate private access or trespass fees — a contrast to some Wyoming units where checkerboarded private and public land forces hunters into tighter corridors. The unit also carries 8% wilderness designation. That's a relatively small slice of the total acreage, and it's well below the threshold where Wyoming's nonresident guide requirement for wilderness areas becomes a practical obstacle for the unit as a whole. Nonresident hunters planning a DIY hunt in Unit 91's general pronghorn habitat should not find wilderness restrictions to be a major factor, though anyone whose hunt plan specifically pushes into the wilderness-designated portion should confirm Wyoming's outfitter requirement applies to that ground.

HuntPilot Analysis: Is Unit 91 Worth Applying For?

Based on the data, Unit 91 earns its reputation. The combination of high public land access (93%), consistently strong harvest success (86-94% across four recent seasons), a favorable buck:doe ratio (55:100 average), and a strong county-level trophy history checks nearly every box a serious pronghorn hunter looks for in a unit.

The catch — and it's a real one — is that this unit is 100% limited-quota. There's no general season safety net, and forum chatter among hunters (including nonresidents comparing point totals) consistently flags Unit 91 as a unit that takes patience to draw, especially compared to lower-demand units that take fewer points. The tag quota data reinforces that Unit 91 is in a growth phase rather than a static one: Type 1 tags jumped from 75 in 2024 to 125 in 2025 to 200 in 2026 — a 60% increase from 2025 to 2026 alone — and Type 7 tags doubled from 25 in 2025 to 50 in 2026. Growing quotas are a meaningful development for hunters who've been watching this unit and waiting; more tags generally means more opportunities to draw, even if it doesn't guarantee an easier pull in any given year.

For a nonresident with a moderate point bank, Unit 91 is a legitimate target — not necessarily a first-year draw, but one worth building toward given the trajectory of increasing tag numbers, high success rates, and trophy potential. For a resident applicant, it's an even stronger recommendation given generally more favorable in-state odds structures. Hunters chasing volume and quick opportunity might do better in an easier-draw unit, but hunters willing to invest points for a quality, high-success, well-managed hunt should have Unit 91 on their short list.

How to Apply

Unit 91 pronghorn tags are allocated entirely through Wyoming's draw system — there is no general season alternative in this unit. Both resident and nonresident hunters must apply for a limited-quota tag; residents and nonresidents draw from separate applicant pools, and nonresidents accumulate preference points that factor into future draw cycles.

Wyoming's pronghorn draw includes multiple hunt types depending on sex and tag structure — for example, the Type 1 and Type 7 tag categories referenced in the quota data above represent distinct draw pools within this unit, each with independent quota trends. Hunters should review the specific hunt type structure for Unit 91 on the current year's regulations before applying, since eligibility, sex designation, and point requirements can vary between hunt types.

Application dates and fees change every cycle, so this article won't cite a specific deadline or cost. For the current application windows, fees, and draw odds for Unit 91, see HuntPilot's Wyoming page at /states/wy, which pulls live data each draw cycle.

Frequently Asked Questions

Is Unit 91 worth applying for as a nonresident? Based on the available data, yes — Unit 91 shows strong harvest success (86-94% over the past four seasons), a favorable buck:doe ratio, a strong trophy history in the surrounding counties, and 93% public land access. The trade-off is that it's a fully limited-quota unit with no general season fallback, so nonresidents should expect to invest preference points rather than draw immediately. Growing tag quotas in recent years (Type 1 up 60% from 2025 to 2026, Type 7 doubled) suggest the unit is becoming more accessible over time.

What is the terrain like in Unit 91? The unit spans a wide elevation range from 6,576 to 13,069 feet across 440,855 acres, indicating varied terrain from lower sagebrush and grassland habitat typical of pronghorn range up into much higher elevations at the unit's edges. With 93% public land, hunters have room to explore this terrain without needing private access agreements.

What is harvest success like in Unit 91? Harvest success has been consistently strong: 94% in 2025 (135 hunters, 127 harvested), 93% in 2024 (75 hunters, 70 harvested), 86% in 2023 (66 hunters, 57 harvested), and 88% in 2022 (429 hunters, 377 harvested). Success rates have trended upward as hunter numbers have decreased in recent seasons.

How big are the pronghorn in Unit 91? The counties overlapping Unit 91 have a strong history of producing trophy-class pronghorn, though those records are attributed at the county level and shared with neighboring units in the same counties. Combined with a healthy 55:100 average buck:doe ratio across recent survey years, the data supports strong trophy potential for hunters who draw a tag here.

Does Unit 91 have a general season for pronghorn? No. Every pronghorn hunt in Unit 91 is limited-quota and allocated through Wyoming's draw system, including hunts for antlered/either-sex animals. There is no over-the-counter or general season option in this unit.
