Pronghorn Hunting in Unit 31/32

The combined GMU 31/32 pronghorn hunt covers the Altar Valley and Baboquivari Plains of southwestern Arizona — one of the driest and most remote pronghorn ranges in the state. AZGFD manages pronghorn here through a limited-draw tag allocation; tag numbers are typically very small, reflecting the open-desert pronghorn population that depends heavily on summer monsoon rainfall. The Tohono O'odham Nation occupies a significant portion of this region, requiring hunters to verify land ownership before accessing any areas.

Where to Find Pronghorn in GMU 31/32

Pronghorn in the combined GMU 31/32 area use the open desert grassland and creosote flats of the Altar Valley and Baboquivari Plains. Herds concentrate where monsoon-driven grass growth is strongest following summer rains.

Open Grassland and Desert Flats

Glass across the broad open bajadas and valley floors early in the day. Pronghorn in this arid environment travel widely for water and forage. A quality spotting scope on a tripod is essential to locate animals at distance across the flat terrain.

Water Catchments

Water is the critical resource in this desert unit. Stock tanks and wildlife water developments on BLM land concentrate pronghorn during dry periods. Pre-season scouting of verified public land water sources pays significant dividends when hunting begins.

How to Hunt GMU 31/32 Pronghorn

The vast flat terrain of GMU 31/32 demands a glassing-first, stalk-second strategy. There is almost no cover for approach, making patience the most important hunting tool.

Vehicle-Assisted Glassing

Drive the BLM roads slowly early morning and glass from the vehicle before committing to foot travel. The desert flat allows you to cover miles of country quickly by vehicle before identifying a target buck and beginning a stalk.

Land Ownership — Critical Check

A significant portion of GMU 31/32 overlaps with the Tohono O'odham Nation and private ranches. Before hunting any area, verify land ownership using AZGFD maps and the BLM surface management layer. Trespassing is a serious violation — do not assume desert country is public land.
