New Mexico Unit 40 Mule Deer Hunting Guide

New Mexico Unit 40 is a limited-quota deer hunting unit in the southeastern part of the state, spanning roughly 2.4 million acres of low-elevation desert and rangeland country, with terrain ranging from 3,771 to 5,586 feet. Every deer hunt in this unit runs through New Mexico's draw system — there is no general, over-the-counter option here. Hunters pursuing mule deer in Unit 40 need to understand that this is fundamentally a limited-entry proposition, and the land ownership picture (just 11% public land) shapes almost every other decision a hunter will make once a tag is in hand.

This is a unit that draws attention because of its harvest numbers, which have held up reasonably well in recent seasons even as public access remains a serious constraint. For hunters evaluating whether to spend an application on Unit 40, the data tells a nuanced story: solid success rates on paper, but an access reality that will frustrate anyone who shows up without a land-access plan already in place.

HuntPilot Analysis: Is Unit 40 Worth Applying For?

The honest answer depends entirely on whether a hunter has, or can secure, access to private land in the unit. With only 11% of Unit 40 classified as public land, the majority of the huntable ground is privately held. That's a critical number — any unit under roughly 45% public land means DIY hunters relying purely on public ground will be working with a small fraction of the total acreage, and in Unit 40's case, that fraction is genuinely thin. This is not a unit where a hunter can show up, study a map the night before, and expect to find open country to still-hunt or glass without running into fence lines and private boundaries almost immediately.

That said, the harvest data suggests hunters who do get access are finding deer. In 2024, 165 hunters harvested 34 animals for a 21% success rate. In 2023, the same number of hunters (165) posted 46 harvests for a 28% success rate — the strongest of the three recent years reported. In 2022, 150 hunters harvested 32 deer, also a 21% success rate. That's a three-year span holding in the low-to-high 20% range, which is a respectable success rate for a limited-quota desert mule deer hunt and indicates the unit isn't simply producing tags with no deer behind them.

Where this gets complicated is the access question layered on top of harvest success. A 21-28% success rate is meaningful context, but it almost certainly reflects a mix of hunters — some with private land access or leases who are finding good hunting, and others confined to scattered public parcels who may be working much harder for the same statistical outcome. HuntPilot's data doesn't break success out by land tenure, so hunters should treat that overall percentage as a unit-wide average, not a guarantee of what a purely public-land hunter will experience.

Bottom line: Unit 40 is worth applying for if a hunter has already lined up access — whether through a landowner relationship, a lease, or a plan to hunt the limited public tracts hard. It is a much riskier application for a hunter with no access plan, given how little of the unit is open to the public. Trophy record data was not available for this unit in the structured context provided, so no trophy-quality assessment can be made here — hunters should not assume this is or isn't a trophy unit without that data.

Harvest Success Rates

Unit 40's harvest numbers over the past three reported seasons show a consistent, moderate level of success for a limited-quota deer hunt:

• 2024: 165 hunters, 34 harvested, 21% success
• 2023: 165 hunters, 46 harvested, 28% success
• 2022: 150 hunters, 32 harvested, 21% success

The hunter counts are notably stable year over year — 150 to 165 hunters across all three seasons — which suggests the tag quota for this unit hasn't fluctuated much recently. The success rate did spike in 2023 to 28%, ten points above the prior year, before settling back to 21% in 2024. That kind of year-to-year swing is common in desert mule deer units where forage conditions, winter severity, and rainfall patterns ahead of the season can meaningfully affect deer movement and visibility. Hunters should view the 21% figure from 2024 as the more recent data point, but weigh the full three-year window (averaging in the low-to-mid 20% range) as the more reliable baseline for expectations.

For a unit with as little public land as Unit 40, these success rates are arguably a positive signal — they indicate hunters are connecting with deer at a rate on par with many public-land-heavy limited-entry units elsewhere in the state, despite the access constraints. HuntPilot's harvest reporting is the source for these figures, and hunters should check the current unit page for any more recent seasons added since this data was compiled.

Access & Terrain

Unit 40 sits at a low elevation band for a New Mexico deer unit, ranging from 3,771 to 5,586 feet, and covers a large footprint of nearly 2.42 million acres. There is no wilderness designation in this unit (0%), so there are no wilderness-specific access restrictions or guide requirements to plan around — hunters are dealing purely with a land-ownership access challenge, not a wilderness-permitting one.

The dominant access issue is straightforward: only 11% of the unit is public land. That means roughly 9 out of every 10 acres in Unit 40 are privately held, and hunters without a private-land arrangement will be restricted to a small patchwork of public tracts scattered across a very large unit. This is exactly the kind of situation flagged by hunters on public forums discussing this unit — one hunter new to Unit 40 was directly warned that without checking a map first to identify exactly where the public parcels lie, a hunt here "could end up frustrating." That's a fair characterization given the numbers.

In terms of terrain character, the country includes low desert rangeland with breaks and caprock formations in parts of the unit, along with flatter plains terrain elsewhere — the kind of topography where elevated features like rim rock edges or caprock breaks can offer natural glassing vantage points over surrounding flats. Hunters scouting the unit should use mapping tools to precisely identify the boundaries of public parcels before the season, since the difference between a productive public tract and adjacent posted private ground can be a single fence line in country like this. HuntPilot's map layers, including public land boundaries, are a useful starting point for that kind of pre-season identification work, letting hunters mark potential glassing points and access routes onto public ground before ever leaving home.

Given the low percentage of public acreage, hunters should not assume "plenty of public access" here — with 11% public land, this unit sits firmly in the category where a majority-private landscape will define the hunt experience for anyone without landowner permission or a lease arrangement.

How to Apply

Unit 40's deer hunts are entirely limited-quota — there is no general or over-the-counter deer season available in this unit. Every hunter pursuing deer here, resident or nonresident, must apply through New Mexico's draw system and be drawn for a specific hunt before hunting.

New Mexico's draw operates as a straightforward random-draw lottery — there are no preference points or bonus points involved. That means every applicant, whether applying for the first time or the fifteenth, has identical odds within their applicant pool for a given hunt choice. There's no benefit to "waiting" or "building points" in New Mexico, since no such point system exists. The only lever hunters have is which specific hunts they choose to list on their application.

New Mexico's draw further separates applicants into resident, nonresident, and outfitter-sponsored pools, each with its own portion of the available tags. Nonresident applicants should expect meaningfully lower odds than residents on the same hunt, since nonresident tags are capped at a smaller share of the total quota — a structural feature of the draw, not a reflection of point status. Applicants typically list multiple hunt choices in order of preference, and the state's draw system works through those choices sequentially.

Because Unit 40 has no general season fallback, a hunter who doesn't draw a specific tag here has no alternative path to hunting deer in this unit that same year — unlike units with general seasons where a hunter can fall back on an OTC-style tag. That makes the draw choice itself the single most important decision hunters make when targeting this unit.

Application dates, fees, and current draw odds for Unit 40 change every cycle and are not included here.

Frequently Asked Questions

What is the terrain like in Unit 40? Unit 40 covers a large area of low-elevation desert rangeland in southeastern New Mexico, with elevations running from 3,771 to 5,586 feet. The terrain includes caprock breaks and flatter plains country. There is no wilderness area within the unit, so hunters won't encounter wilderness-specific access restrictions. The defining terrain challenge isn't ruggedness — it's the extremely low percentage of public land (11%), which limits where hunters can legally access and hunt regardless of how the terrain itself looks on a map.

What is harvest success like in Unit 40? Recent harvest data shows success rates of 21% in 2024, 28% in 2023, and 21% in 2022, with hunter numbers holding steady between 150 and 165 across those three years. That's a moderate, fairly consistent success rate for a limited-quota deer unit, though hunters should remember this figure reflects the unit as a whole and likely includes a mix of hunters with private land access and those working the limited public tracts.

How big are the deer in Unit 40? Trophy record data is not available for this unit in the structured data reviewed for this article. Hunters interested in trophy potential specifically should not assume a size class based on harvest success alone — those are separate metrics — and should look for additional unit-specific trophy information before making decisions based on trophy expectations.

Is Unit 40 worth applying for? It depends heavily on access. The unit's harvest success rates (21-28% over the last three reported years) are solid for a limited-quota hunt, but with only 11% public land, hunters without an existing private-land arrangement or lease will be confined to a small share of the unit's nearly 2.42 million acres. Hunters with access lined up should view this as a reasonably productive draw option; hunters without access should carefully map the public parcels before applying, since forum reports from recent Unit 40 hunters confirm that unfamiliarity with the public/private boundary lines has led to frustrating hunts.

Do I need a guide or outfitter to hunt Unit 40? No wilderness area exists within Unit 40 (0% wilderness), so there is no state-mandated guide requirement tied to wilderness access as there would be in some other western states. That said, given how little public land is available, many hunters choose to work with a local landowner, lease, or outfitter arrangement simply to gain access to huntable ground — not because it's legally required, but because it's often the most practical way to hunt this unit effectively.
