Western Watersheds Project, Rocky Mountain Wild, and WildEarth Guardians

(the “Conservation Groups”) challenged, under the Administrative Procedure Act

(“APA”), the United States Forest Service (“USFS”) Thunder Basin National

Grassland 2020 Management Plan Amendment (the “2020 Plan Amendment”). The

district court concluded the 2020 Plan Amendment complied with both the National

Environmental Policy Act (“NEPA”) and the Endangered Species Act (“ESA”)

On appeal, this court determined the 2020 Plan Amendment failed to comply

with NEPA. Western Watersheds Project v. Vilsack, No. 23-8081, 2024 WL

4589758, at *15 (10th Cir. Oct. 28, 2024) (unpublished) (Western Watersheds I). We

remanded to the district court “for consideration of the appropriate remedy.” Id.

It concluded the proper remedy is remand to the USFS without vacatur of the 2020

Plan Amendment.

The Conservation Groups now seek to challenge the district court’s refusal to

order vacatur of the 2020 Plan Amendment as part of the remand. Because they have

failed to establish that we have jurisdiction to review that determination, we dismiss

this matter.

I. BACKGROUND

A. Initial District Court Proceedings

“In 2021, the Conservation Groups filed suit under the APA against the USFS

in the United States District Court for the District of Columbia, seeking a declaratory

judgment that the 2020 Plan Amendment” was unlawful under NEPA and the ESA

“and an injunction setting it aside.” Id. at *4.

“The State of Wyoming intervened and then successfully moved for the action

to be transferred to the District of Wyoming.” Id. at *5. “Next, the USFS produced

the agency record, and the parties briefed the merits of whether to set aside the 2020

Plan Amendment under the APA.” Id. “The Wyoming district court ultimately

declined to set aside the 2020 Plan Amendment, agreeing with the USFS and the

State of Wyoming that” the 2020 Plan Amendment did not violate NEPA or the ESA.

Id. “The Conservation Groups timely appealed the final judgment upholding the

2020 Plan Amendment.” Id.

B. Initial Appeal

The Conservation Groups argued on appeal that “the USFS had provided an

impermissibly narrow and unreasonable Purpose and Need statement” for the 2020

Plan Amendment, “failed to analyze a reasonable range of alternatives, and failed to

take a hard look at the effects of the 2020 Plan Amendment.” Id. We agreed with

these arguments. Id. As a result, we did not reach the Conservation Groups’ ESA

claim.

3 Appellate Case: 25-8026 Document: 60-1 Date Filed: 06/26/2026 Page: 4

In discussing “the appropriate remedy,” we noted that “[t]he Conservation

Groups briefly argue[d] that the USFS’s violation of NEPA warrant[ed] vacatur.” Id.

at *15. We said that “[t]his court has adopted a two-prong, fact-sensitive test for

determining whether vacatur is the appropriate remedy for an APA violation: (1) the

seriousness of the agency action’s deficiencies (and thus the extent of doubt whether

the agency chose correctly), and (2) the disruptive consequences of an interim change

that may itself be changed.” Id. (alterations and quotations omitted). The test comes

from Allied-Signal, Inc. v. U.S. Nuclear Regulatory Commission, 988 F.2d 146, 150-

51 (D.C. Cir. 1993). We noted “that application of the Allied-Signal factors requires

a fact-intensive inquiry that is typically left to the discretion of the district court.”

Western Watersheds I, 2024 WL 4589758, at *15 (alterations and quotations

omitted).

We decided that “[b]ecause the Allied-Signal factors were not considered by

the district court, and because the parties d[id] not provide any discussion of the

factors on appeal,” the proper course was to “remand to the district court with

instructions to apply these factors in the first instance to determine the appropriate

remedy.” Id. In other words, we remanded for the district court to determine

whether remand to USFS should be with or without vacatur.

C. District Court Proceedings on Remand

On remand in the district court, the parties filed additional briefs discussing

“the question of remedy,” particularly whether vacatur was appropriate. App., Vol. 1

4 Appellate Case: 25-8026 Document: 60-1 Date Filed: 06/26/2026 Page: 5

at 101. No party questioned the need for a remand to the agency. The Conservation

Groups argued that vacatur was the presumptive and appropriate remedy under the

APA, and that the Allied-Signal test supported vacatur because the agency’s

violations were serious and because vacating the 2020 Amendment would not be

disruptive. The USFS and Wyoming argued that the Allied-Signal factors supported

remanding the 2020 Plan Amendment to the agency without vacatur.

The district court ordered remand to the USFS without vacatur of the 2020

Plan Amendment, concluding that both Allied-Signal factors favored remand without

vacatur. It did not enter a final judgment.

The Conservation Groups seek to appeal from the remand order.

D. This Appeal

Shortly after the Conservation Groups filed their notice of appeal, the clerk of

this court issued an order directing the parties to address in their briefs whether this

court has jurisdiction to review the district court’s order. They have done so.

II. DISCUSSION

“We review questions of our appellate jurisdiction de novo.” City of

Albuquerque v. Soto Enters., Inc., 864 F.3d 1089, 1091 (10th Cir. 2017). The

appellant “bears the burden of establishing appellate jurisdiction.” SeedX, Inc. v.
