A Federal Judge Just Shut Down Part of the Oregon Dunes — Over a Weasel

If you ride the Oregon Dunes, you need to know about this before you load the trailer. A federal judge just closed two chunks of the dune system to motorized use and slapped a nightly curfew on a much bigger area — and it happened fast, with almost no warning to riders.

What actually got closed

Late on August 9, U.S. District Judge Ann Aiken granted a preliminary injunction ordering the Forest Service to close Banshee Hill (northeast of the Umpqua #2 staging area) and the southwestern edge of Umpqua Dunes (south of Umpqua #3) to off-highway vehicles. On top of that, the entire Middle Riding Area is now under a nightly curfew — no OHVs between 10:30 p.m. and 6:00 a.m. The Forest Service has to rope off the closed zones, post signage, and keep replacing that signage if it gets torn down or stolen (OPB; Jefferson Public Radio).

The order landed right before a scheduled UTV event on the coast, which is its own kind of gut punch if you already had the weekend planned.

Why: it's about the coastal marten

This goes back to a 2024 lawsuit from the Center for Biological Diversity, arguing the Forest Service never properly analyzed how OHV traffic in the dunes affects the coastal marten — a small, secretive relative of the weasel family that's been listed as threatened under the Endangered Species Act since 2020. Fewer than 400 are estimated to survive on the entire Oregon and California coast, with roughly 70 of them living in the Oregon Dunes National Recreation Area itself (Center for Biological Diversity).

Judge Aiken sided with the plaintiffs, finding the agency likely violated federal law by authorizing motorized recreation without adequately reducing the risk to marten habitat — and that the harm to the animal would be irreparable if the court waited for a full trial to act. The 10:30 p.m.–6 a.m. curfew specifically targets the marten's peak foraging and hunting window, which is the court's way of saying the timing of the ride matters as much as the location.

This is temporary — for now

Important distinction: this is a preliminary injunction, not a final ruling. It stays in place while the underlying case works through the court, and the judge could adjust the terms as that plays out. But "temporary" doesn't mean "irrelevant" — this is the kind of order that becomes the starting point for whatever permanent travel-management decision comes out the other side. Riders in other dune systems and OHV areas dealing with ESA-listed species nearby (marten, snowy plover, and similar cases have all been used this way before) should read this as a preview, not a one-off.

BlueRibbon Coalition is already organizing pushback and fundraising for the legal fight to keep the rest of the dunes open (BlueRibbon Coalition). If you ride the Oregon Dunes regularly, that's the group to watch for how this heads to a longer-term resolution — and where public comment, when it opens, will actually matter.

What to do if you're headed there

Respect the roped-off zones and the curfew — a fresh injunction is exactly the kind of thing land managers and advocacy groups will be watching closely for violations, and getting cited (or giving ammunition to the "OHVs can't be trusted to self-regulate" argument) helps nobody. Check current Siuslaw National Forest closure notices before you go; boundaries on a court order don't always match what's easy to see from the seat of a quad or sand rail.

This is the same reason we built hazard reporting and ride logging into BraapTrax the way we did — closures like this move fast, and the riders who actually track where they've been are the ones who can flag a new rope line or a moved boundary before someone else finds out the hard way. Log your dune runs, flag anything that's changed on the ground, and keep an eye on this one — it's not over.
