Procedural read

S.1377 is a small, bipartisan, Senate-originated parks bill that just cleared a Subcommittee on National Parks hearing and faces friendly regional politics but a crowded year-end calendar; most likely path is hitching a 2026 public-lands/parks package rather than stand‑alone—composite viability score: 3/5.

Bottom line

Composite score: 3/5 — plausible rider on a parks or lands package; unlikely to move stand‑alone in December 2025. [1]Congress.gov (Library of Congress) — S.1377 — Congress.gov main bill page[3]Office of Sen. Steve Daines — Daines chairs National Parks Subcommittee hearing…

Procedural Viability Check (factor-by-factor)

  1. Chamber of Origin — Upward pressure: Senate-originated with bipartisan pairing (Hoeven/Kaine). That’s a better starting position than a House-only messaging bill. [1]Congress.gov (Library of Congress) — S.1377 — Congress.gov main bill page
  2. Vehicle Type — Neutral/soft positive: Narrow, place‑based authorizing bill; classic candidate to fold into a broader ENR “parks/lands” package rather than claim scarce stand‑alone floor time. Daines has been touting a parks vehicle (America the Beautiful/Legacy Restoration Fund work), providing a plausible hook. [3]Office of Sen. Steve Daines — Daines chairs National Parks Subcommittee hearing…
  3. Senate Threshold — Mixed: Not reconciliation‑eligible; needs 60 if contested. These local park management bills often clear by UC or en bloc if noncontroversial, but ENR Chair Lee’s posture on federal land mandates means staff will likely look for tweaks or package cover. [2]U.S. Senate Energy and Natural Resources Committee — ENR subcommittee assignmen…
  4. Committee Path — Generally favorable: Subcommittee hearing held; panel leadership (Daines/King) is experienced at assembling bipartisan parks bundles. Full committee under Lee may want management‑flexibility language but is unlikely to block a members’ local priority once packaged. [1]Congress.gov (Library of Congress) — S.1377 — Congress.gov main bill page[2]U.S. Senate Energy and Natural Resources Committee — ENR subcommittee assignmen…
  5. Must‑Pass Potential — Primary path: Year‑end/minibus or a 2026 public‑lands/parks package is realistic; NDAA is moving now and is an unlikely home this late. [9]Reuters — Reuters: House passes FY26 NDAA (Dec. 10, 2025)
  6. Budget Scorekeeping — Low risk: No CBO score posted yet; directive/management provisions imply minimal direct spending, manageable via existing NPS ops (monitoring, planning, contraception), but staff will want a “no significant cost” confirmation before en bloc. [10]Web search · turn 0 #4
  7. Calendar Math — Tight for 2025; better in early/mid‑2026: With NDAA on the floor and limited December days, realistic movement is report/hold for inclusion in a 2026 package ahead of the July 4 semiquincentennial push Daines flagged.

Political and stakeholder signals

  • Local salience: TRNP horses have high in‑state visibility; NPS backed off full removal in 2024 after delegation pressure—reduces opposition risk to a codified floor of 150 with management sideboards. [12]Associated Press — AP: NPS to maintain TRNP wild horses (Apr. 25, 2024)
  • Agency/manageability: NPS is already doing monitoring/contraception and herd management at TRNP; codifying a floor plus plan/reporting aligns with current practice, easing executive-branch pushback once details are negotiated. [13]National Park Service — NPS: Horses of Theodore Roosevelt National Park (manage…
  • Sponsor leverage: Hoeven sits on ENR (and chairs Water & Power Subcommittee), improving staff‑level negotiating lanes for inclusion in an ENR package. [2]U.S. Senate Energy and Natural Resources Committee — ENR subcommittee assignmen…
  • Messaging optics: Bipartisan (R‑ND/D‑VA) and park‑specific—typically low‑salience for national ideological fights, which helps in end‑game negotiations. [1]Congress.gov (Library of Congress) — S.1377 — Congress.gov main bill page

  • Score rationale: Bipartisan Senate origin, friendly subcommittee posture, and clear package vehicles offset a lack of House companion and the late‑year calendar.

  • Best path: Aim for inclusion in an ENR bipartisan lands/parks package assembled in early 2026; pre‑clear with HNR majority staff to avoid last‑minute House holds. [2]U.S. Senate Energy and Natural Resources Committee — ENR subcommittee assignmen…
  • Near‑term to‑dos: (1) Secure informal bipartisan staff draft with any NPS‑requested flexibility on removals language; (2) line up a House sponsor from HNR majority; (3) obtain a quick “no significant cost” read from CBO before package assembly.
