HB 1603 New Hampshire House · 2026 Regular Session

requiring the executive director of the department of fish and game to adopt rules relative to procedures for verifying accuracy of records collected relative to threatened and endangered wildlife and ensuring landowner permission is granted for the gathering of such record.

HB 1603 requires state agencies to provide current, verifiable proof of an endangered or threatened species' presence - such as GPS coordinates, timestamped photos, and official credentials - before restricting land use for that species' habitat. It directly affects landowners whose property may face restrictions and state agencies like Fish and Game. The bill mandates that any evidence used must include written landowner permission or an administrative warrant for data collection. It also prohibits agencies from requiring new biodiversity surveys as a condition for land use applications. This policy change aims to ensure land use decisions are based on recent, documented evidence rather than outdated data.

What changed between versions

Version adopted by both bodies CHAPTERED FINAL VERSION · 4 edits
MODERATE
This diff reflects the standard transition of HB 1603 from its adopted bill form to its final enacted chapter form (Chapter 236). No substantive policy changes were made; all differences are technical and formatting-related, including renumbering sections with the chapter number, removing the fiscal note, adding approval and effective dates, and adjusting line breaks and alignment.
TECHNICAL

Section numbers were updated to include the chapter number (e.g., '1' became '236:1', '2' became '236:2'), which is standard when a bill is enrolled as a chapter.

The fiscal note section was removed entirely, as it is not part of the final enacted law text.

Header changed from 'VERSION ADOPTED BY BOTH BODIES' to 'CHAPTER 236 - FINAL VERSION', and page headers were updated accordingly. Line breaks and spacing throughout were adjusted for final formatting.

TIMELINE

Approval date (July 02, 2026) and effective date (August 31, 2026) were added at the end of the document, which is standard for chaptered bills.
