Montana BLM Grazing Leases

Who Controls Montana’s Public Grazing Land?

For the first time, explore an interactive visualization of every BLM grazing allotment in Montana—and see which ranchers and companies hold the permits.

Interactive map of Bureau of Land Management grazing allotments across Montana — 4,171 allotments carrying 1,115,080 permitted AUMs (99% of all permitted BLM AUMs in the state), shaded by permitted AUMs. It uses the same five-step grazing-volume scale as the Forest Service map, so the two can be read side by side. Click any allotment for its field office, permitted and suspended AUMs, and public acres.

Boundaries & centroids: BLM National Grazing Allotment Polygons (joined on ST_ALLOT). AUM data: BLM Rangeland Administration System “Allotment Information Report,” all Montana field offices. One animal-unit-month (AUM) is essentially one USFS head-month, so both maps share the same shading bins. 4,171 of 4,214 permitted allotments mapped; the 43 unmatched carry ~0.5% of AUMs.

Note: the map above reflects the latest BLM refresh (4,171 allotments; 1,115,080 AUMs). The operator and field-office tables further down are from an earlier BLM Rangeland Administration System pull (current to January 2026) and show a smaller allotment count; a full refresh of those tables is pending.

How to Use the Map

The interactive map above displays all BLM grazing allotments in Montana using a cluster system that groups nearby allotments together for easier navigation.

Reading the Map

Allotments are shaded by permitted AUMs (animal-unit-months) on a five-step scale — the same scale used on the Forest Service map, so the two can be read side by side. Lighter shades mark lighter grazing loads and the darkest shade marks the heaviest; the map’s legend lists the exact AUM breakpoints. Nearby allotments are grouped into numbered clusters, and the number inside each circle shows how many allotments fall in that area.

Navigating the Map

1. Click any cluster to zoom in and see smaller groupings or individual allotments
2. Keep clicking to drill down until you see individual allotment markers
3. Click an individual marker to see details: allotment name, operator, acreage, and AUMs
4. Use the +/- buttons or scroll to zoom manually
5. Drag the map to pan around Montana

Tip: The eastern half of Montana (Miles City, Billings areas) has the densest concentration of BLM grazing allotments.

Largest Grazing Lease Holders in Montana

Based on permitted Animal Unit Months (AUMs) from BLM’s Rangeland Administration System:

Rank	Operator	Acres	AUMs	Field Office(s)
1	CRC Montana, LLC	7,000	1,750	Lewistown / Malta
2	Falls Coulee, LLC	5,000	1,250	Dillon
3	Russell, Louis (LP Reed Ranch)	4,600	1,150	Dillon
4	Arthur, Michelle	4,200	1,050	Dillon
5	Steppler, Verlin & Cody	4,200	1,050	Lewistown
6	Peters, Roger and Carrie Ann	4,100	1,025	Butte
7	Nesselhuf, John W & Marjorie A	3,900	975	Dillon

9	Oedekoven Family Trust	3,600	900	Malta
10	Holden Land and Livestock, LLC	6,372	796	Billings

Note: Holden Land and Livestock ranks #10 by AUMs but #2 by total acreage, reflecting differences in carrying capacity across allotments.

Why Public Land Grazing Data Matters

In December 2025, ProPublica and High Country News published a major investigation revealing that roughly two-thirds of all BLM grazing acreage nationwide is controlled by just 10% of permit holders. The investigation named billionaires like Stan Kroenke (LA Rams owner) and Rupert Murdoch, plus corporations like J.R. Simplot Co., as among the largest beneficiaries of below-market federal grazing fees.

However, that investigation—impressive as it was—did not create a public tool for exploring the data. Journalists, researchers, and citizens who want to know who holds grazing leases in their state still have to file FOIA requests or manually query BLM’s clunky database systems.

Honest Cattle is building what should already exist: a free, public, state-by-state visualization of who controls grazing on America’s public lands.

Montana is our first state. More are coming.

Data Sources & Methodology

This visualization combines data from official BLM sources:

• BLM Rangeland Administration System (RAS) — Operator names, authorization numbers, permitted AUMs, addresses (where releasable)
• BLM GIS Data Hub — Allotment boundaries, geographic coordinates, acreage calculations
• Montana BLM Field Offices — Billings, Butte, Dillon, Havre, Lewistown, Malta, Miles City, Missoula

All data is derived from public records. Operator contact information is included only where BLM has marked it as releasable. Data current as of January 2026.
