Arizona Unit 43A Bighorn Sheep Hunting Guide

Unit 43A sits in the desert country of southwestern Arizona, a sprawling 602,613-acre unit where nearly every acre — 96% — is public land. For hunters chasing desert bighorn sheep, this unit represents one of the most sought-after and difficult-to-draw opportunities in the state, and understanding what the data actually says about it is critical before spending a single application point.

This is not a unit where hunters wander in with an over-the-counter tag. Every bighorn sheep hunt in Unit 43A is limited-quota and allocated through Arizona's draw system, with no general season path for any hunter, resident or nonresident. That structure alone tells hunters most of what they need to know about how competitive and exclusive this opportunity is. Elevation in the unit ranges from just 209 feet up to 3,274 feet, a modest but rugged span typical of Sonoran desert sheep range — broken volcanic ridgelines, steep-walled canyons, and open desert flats that demand serious physical conditioning and long-range glassing to hunt effectively.

With zero percent wilderness designation, access into 43A is more straightforward than some of Arizona's other sheep units, though the terrain itself remains the real obstacle. This is classic low-desert bighorn habitat, and hunters drawing a tag here should expect to invest real time in scouting rugged, exposed country before the hunt even begins.

HuntPilot Analysis: Is Unit 43A Worth Applying For?

For desert bighorn sheep hunters, the honest answer is yes — with the caveat that this is a long-term investment, not a quick-draw opportunity. Every hunt in this unit is limited-quota, meaning tag numbers are intentionally kept low to protect the herd and preserve trophy quality, and that scarcity is exactly what makes 43A worth pursuing for hunters willing to play the long game.

The harvest data reinforces just how limited this opportunity is. In 2025, 2023, and 2024, only 2 hunters carried tags into the unit each year, and both hunters were successful in each of those seasons — a 100% success rate. That consistency across three consecutive years is a strong signal: hunters who draw a tag in 43A and put in the scouting time are converting those opportunities into harvests at an exceptionally high rate. This isn't a unit where tag holders are wandering home empty-handed.

The 2022 harvest figure — 5 hunters and 100 harvested animals for a reported 2000% success rate — is clearly an aggregation anomaly rather than a literal reflection of individual hunter success, likely reflecting a broader survey or population-count figure folded into the harvest report for that year rather than 100 individual tag holders filling tags. Hunters should weigh the three consistent years (2023–2025) more heavily than the 2022 outlier when assessing what a drawn tag in this unit typically produces.

Trophy potential is where 43A separates itself from average desert sheep units. The counties overlapping this unit carry a strong history of trophy-class record-book entries, indicating this general geography has consistently produced rams worth calling once-in-a-lifetime trophies over multiple decades. Because record-book entries are logged by county rather than by unit, that trophy pedigree is shared with neighboring units in the same county footprint — but it still speaks to the quality of genetics and habitat in this broader landscape, and it's a meaningfully positive signal for any hunter fortunate enough to draw here.

The wildlife survey data adds further context. Across two survey years between 2022 and 2025, biologists recorded an average buck:doe ratio of 66:100 and an average of 52 animals observed per survey. For desert bighorn sheep, ratios in this range with a modest observed population suggest a functioning, breeding herd, though hunters should recognize that a two-survey sample is a limited dataset — not enough to draw firm long-term trend conclusions, but enough to confirm the herd is present and active in the unit.

Given nearly full public land access (96%), the elimination of wilderness-related access restrictions, and a herd that appears healthy based on available survey data, Unit 43A is absolutely worth applying for if a hunter is serious about pursuing desert bighorn sheep in Arizona. The catch — and it's a significant one — is the draw itself. This is one of the most competitive tag categories in North American big game hunting, and hunters should expect this to be a multi-year, if not multi-decade, point-building strategy rather than a near-term hunt.

Harvest Success Rates

The recent harvest record in Unit 43A is remarkably consistent for the three most recent normal seasons on record. In 2025, both hunters who drew tags harvested rams, matching the same 100% success outcome recorded in 2024 and 2023. Three straight years of 100% success with small, tightly controlled hunter numbers (2 hunters each year) indicates that Arizona Game and Fish is managing this unit's tag allocation conservatively, prioritizing hunt quality over volume. Hunters who draw a 43A sheep tag are, based on this track record, extremely likely to fill it — but that success starts well before opening day, built on scouting, physical preparation, and often professional glassing help given the vastness and ruggedness of the terrain.

The 2022 data point (5 hunters, 100 harvested, 2000% success) does not fit this pattern and should not be used to set expectations. It almost certainly reflects a different reporting methodology or a merged data set rather than five individual hunters harvesting 100 sheep. HuntPilot's unit data flags this figure for transparency, but hunters planning their season should anchor expectations to the 2023–2025 window instead.

Trophy Quality

Desert bighorn sheep hunters targeting Unit 43A can take real encouragement from the trophy record history tied to the counties overlapping this unit. That geography has a strong trophy history, with entries logged consistently enough to indicate more than a one-off exceptional ram — this is a landscape that has repeatedly produced record-class rams over time. Because these entries are attributed at the county level rather than unit-specific boundaries, that trophy legacy is technically shared across 43A and its neighboring units, but it remains a meaningful indicator of the quality of genetics, age structure, and habitat productivity in this part of Arizona's desert sheep range.

Hunters should not expect every ram taken here to be a record-book animal — most desert bighorn tags nationwide are filled by rams that represent a genuine trophy for the hunter without cracking record-book thresholds. But the underlying data suggests 43A and its surrounding counties are capable of producing exceptional, top-tier rams with some regularity, which is a significant factor for any hunter deciding where to focus limited application points.

Herd Health & Population Trends

The wildlife survey data available for Unit 43A spans two survey years between 2022 and 2025, showing an average buck:doe ratio of 66:100 and an average of 52 sheep observed per survey. For desert bighorn sheep, a ratio in this range is generally considered a positive sign of a well-structured herd with adequate ram representation relative to ewes, supporting sustained hunt quality over time.

That said, two survey years is a small sample, and hunters should treat this as a snapshot rather than a definitive trend line. The observed population count of roughly 52 animals per survey reflects the naturally sparse density of desert bighorn sheep across vast, rugged low-desert terrain — these are not high-density herds like elk or mule deer, and successful hunts depend heavily on covering large amounts of country and identifying individual rams through sustained glassing rather than relying on high encounter rates.

Access & Terrain

Unit 43A offers exceptional public land access, with 96% of its 602,613 acres open to public hunting. That access ratio is about as favorable as it gets in the West, and it removes one of the biggest logistical headaches hunters face in other desert sheep units where private land and negotiated access complicate hunt planning.

Elevation across the unit runs from 209 feet up to 3,274 feet, a relatively low and compact vertical range that reflects classic low-desert bighorn habitat rather than high-alpine sheep country. Expect broken volcanic mountain ranges, rocky escarpments, washes, and open desert flats — terrain that rewards long-range spotting scope work as much as physical hiking ability. The zero percent wilderness designation means motorized access on existing routes is generally more available here than in wilderness-designated sheep units elsewhere in Arizona, which can be a meaningful advantage for scouting efficiency and gear transport, though the terrain itself remains physically demanding regardless of vehicle access to trailheads.

Given the vast footprint of the unit and the sparse, scattered nature of desert bighorn populations, hunters drawing a tag here should plan on extensive pre-season scouting. HuntPilot's mapping tools, including public land overlays, can help hunters identify likely glassing points and access corridors across this expansive, mostly public landscape before ever setting foot in the field.

How to Apply

Because every bighorn sheep hunt in Unit 43A is limited-quota, there is no walk-in or general-season path to hunting this unit — every hunter, resident or nonresident, must apply through Arizona's draw system to have a chance at a tag. Arizona's draw structure allocates a portion of tags to bonus-point-weighted random drawing, meaning accumulated points increase a hunter's statistical odds without functioning as a strict preference queue — no point total guarantees a tag outright, and successful applicants restart their point accumulation after drawing.

Resident and nonresident applicants are evaluated in separate pools, and nonresident competition for Arizona desert bighorn sheep tags is intense, often requiring many years of accumulated points before drawing becomes realistic even in favorable units. Hunters serious about eventually hunting Unit 43A should treat point accumulation as a long-term strategic commitment rather than something to approach opportunistically.

Application dates, fees, and current draw odds for Unit 43A change every draw cycle. For the most current deadlines, application fees, and draw odds specific to this unit and hunt type, hunters should check HuntPilot's Arizona state page and the Unit 43A page directly, or consult the Arizona Game and Fish Department's published draw information.

Frequently Asked Questions

Is Unit 43A worth applying for as a desert bighorn sheep hunter? Based on available data, yes. The unit combines a strong recent harvest success rate for hunters who draw tags, a favorable public land percentage of 96%, and a trophy history tied to the surrounding counties that suggests genuine potential for a record-class ram. The primary obstacle is the draw itself, which is extremely competitive and typically requires a long-term point strategy.

What is harvest success like in Unit 43A? In the three most recent normal seasons on record — 2025, 2024, and 2023 — every hunter who drew a tag in Unit 43A harvested a ram, reflecting 100% success in each of those years with just 2 hunters afield annually. That consistency suggests hunters who draw tags here and put in adequate scouting time convert their opportunity into a harvest at a very high rate.

How big are the bighorn sheep in Unit 43A? Specific trophy scores aren't part of this assessment, but the counties overlapping Unit 43A carry a strong history of record-book entries, indicating the broader area has consistently produced exceptional, trophy-class rams over time. That trophy legacy is shared with neighboring units in the same county footprint, but it reflects positively on the genetic and habitat quality of the region as a whole.

What is the terrain like in Unit 43A? The unit spans low desert country from 209 to 3,274 feet in elevation, characterized by broken volcanic ridgelines, rocky canyons, and open desert flats typical of Sonoran desert bighorn habitat. With 0% wilderness designation, motorized access to trailheads is generally more available than in wilderness-restricted sheep units, though the terrain itself demands significant physical effort and long-range glassing to hunt effectively.

How healthy is the bighorn sheep herd in Unit 43A? Survey data from two years between 2022 and 2025 shows an average buck:doe ratio of 66:100 and roughly 52 animals observed per survey, suggesting a functioning herd with solid ram representation. However, this is a limited two-year sample, and hunters should view it as a positive but preliminary indicator rather than a definitive long-term trend.
