440+ ranger district contacts

Phone numbers, addresses, and permit availability for districts across USDA Regions 1–10, organized so you can find what you need in seconds.

Organized by USDA region

Structured like a field reference, not a data dump. Regional introductions cover target species, color-coded seasonal windows, road access timing, and permit notes — organized the way you actually plan a trip.

Living document philosophy

We keep it updated. Buyers can submit corrections directly through this site, and verified updates are posted to the buyer updates page.

Who this is for

This directory was built by a collector, for collectors. If you've ever spent an afternoon on hold with a ranger district trying to figure out whether you even need a permit — this is for you. No more guessing, no more dead ends. Just the contacts you need, organized the way you'd actually use them.

What's covered — and what isn't

This edition covers 440+ ranger district offices across 85+ National Forests and Grasslands — the forests most relevant to yamadori collectors based on species availability, access, and permit history.

The one gap: R5 Southern California forests (Angeles, Cleveland, Eldorado, San Bernardino, Sequoia, Sierra, Six Rivers, and Stanislaus NFs) are not included due to extreme permit restrictions and urban access pressure. For those forests, contact their Supervisor's Offices directly via fs.usda.gov.

A note on accuracy

This directory contains the most current publicly available contact information for every ranger district listed, verified against official USDA sources at the time of compilation in early 2026.

However, this information changes — and it changes without warning. Phone numbers are reassigned. Offices merge, relocate, or temporarily close due to staffing shortages. Hours are reduced or suspended seasonally. Permit policies shift with new forest plans, fire seasons, and budget cycles. A district that issues permits freely this year may suspend them next year with no public announcement.

Use this directory as your starting point — to find the right office and the right number. Then make the call. Confirm hours before you drive. Confirm permit availability before you plan a trip. A two-minute phone call prevents a wasted day.

This is a living directory. As a buyer, you'll have access to all verified updates and corrections as they're confirmed. If you find something out of date, submit it at humblebonsai.com/corrections — every correction makes it better for everyone.
