Overview
Unit 31 is the largest game management unit in New Mexico, covering the far southeast corner of the state across Lea County and its oil and gas country. This is Llano Estacado plains hunting: flat, open expanses of grassland, mesquite and shinnery-oak sand hills broken only by the Caprock escarpment (Mescalero Ridge, Nimenim Ridge) and the Loco Hills. Pronghorn are the signature quarry and run high success, while desert mule deer hold in the sand-hill and mesquite cover. There is no national forest and no elk here — access is dominated by private ranches and oilfield land.
Terrain
Vast open plains with shallow swales, dune-like sand hills and scattered playas. The only real relief is the Caprock (Mescalero Ridge) and the Loco Hills; much of it walks like a beach.
Cover: Shinnery oak and sand sage on the dunes, mesquite thickets, shortgrass and mid-grass prairie, yucca and scattered playa grassland.
Landmarks: Mescalero Ridge (The Caprock) · Nimenim Ridge · Loco Hills · Llano Estacado
Access
The northern and eastern portions are overwhelmingly private ranch, and deer and antelope are mostly on private land. Scattered BLM tracts and State Trust sections provide the public opportunity, but they are checkerboarded and heavily crossed by oilfield roads and leases. There is no E-PLUS relevance (no elk). Confirm boundaries carefully — a lot of ground that looks open is deeded ranch.
Managers: private ranch, BLM, NM State Trust
Access points: US-62/180 corridor (Hobbs–Carlsbad) · NM-529 / Loco Hills area · County and oilfield roads off Hobbs, Eunice and Jal · BLM access tracts along the Caprock
Species notes
Pronghorn
abundant qualityPronghorn are the headline species and hunts run very high success on the open plains, though the best bucks and most animals hold on private ranch grassland.
- →Glass long across flats and shallow swales from high points on the Caprock
- →Spot-and-stalk using terrain folds and windmills for cover
- →Watch water tanks and windmills in the heat
- →Secure private access early — most animals are on deeded land
Mule Deer
common opportunityDesert mule deer inhabit the shinnery-oak sand hills and mesquite, with the better bucks reported in the southern part of the unit toward Carlsbad; deer likewise favor private cover.
- →Still-hunt and glass the shinnery and mesquite sand hills
- →Expect a walking hunt — plan on covering 5+ miles a day in loose sand
- →Hunt early and late as deer move to feed
- →Work the edges of dune fields and playa margins
Pro tips
- →Lock down private-ranch access well ahead of the season — the great majority of deer and antelope are on deeded land.
- →Hunt from the Caprock rim and high tank stands to glass miles of flat country.
- →Plan for a walking hunt in soft sand; break in your boots.
- →Windmills and stock tanks are magnets in the heat — glass them.
- →Mind active oilfield infrastructure and truck traffic when planning stalks.
Watch out for
- !Private ranch dominates the north and east — trespass risk is high and public tracts are checkerboarded.
- !State Trust sections require a NMDGF recreational access permit.
- !Little water, less shade, and extreme early-season heat on the open plains.
- !Heavy oilfield traffic, well sites and lease roads throughout the unit.
- !Loose sand and long flat distances make it physically taxing despite lack of elevation.
Logistics
Hobbs is the main hub for lodging, fuel and supplies, with Eunice, Jal and Carlsbad on the fringes. County and oilfield roads are extensive but sandy; 4WD helps in the dune country. Expect heavy oilfield-truck traffic and active well sites throughout.
