- Federal agenciesProvides Congress and the public a searchable database to monitor federal litigation costs and settlements.
Endangered Species Transparency and Reasonableness Act of 2025
Subcommittee Hearings Held
The bill amends the Endangered Species Act to require agencies to publish online the scientific and commercial data supporting listing rules, share that data with affected States before final listings, and explicitly treat State, Tribal, and county submissions as part of the “best scientific and commercial data available.” It also requires an annual, detailed report and a public, searchable database of federal expenditures related to ESA suits, and aligns fee-award procedures with existing federal statutes. Limited exceptions are provided for state-law-protected information and classified Department of Defense material.
Disclosure vs. protection of sensitive species location data
Relative to its intended legislative type, this bill is a substantive statutory amendment to the Endangered Species Act that is comparatively specific about what must be published, who is responsible, and timelines, and that integrates with existing statutory provisions.

Agency heads must supply requested information and certain procedural adjustments to fee awards are specified.
Narrow, administrative focus helps but subject touches contested policy and litigation incentives; Senate hurdles and stakeholder opposition lower odds.

Why the argument around this bill splits.
Disclosure vs. protection of sensitive species location data
Skeptical.
Appreciates transparency and inclusion of state and tribal data, but worries this bill could endanger species by forcing disclosure of sensitive location data and empower anti-conservation litigation.
Concerned about administrative burden and whether protections for sensitive biological or Tribal information are sufficient.
Cautiously supportive of increased transparency and state cooperation but attentive to implementation tradeoffs.
Sees value in a searchable litigation-expenditures database and clearer data flows to States, while wanting safeguards for sensitive information and fiscal/administrative feasibility.
Would favor modest adjustments to protect classified, personal, and ecologically sensitive data and ensure realistic deadlines and funding.
Favorable.
Endorses transparency, state involvement, and disclosure of federal litigation costs as checks on agency discretion.
Views the bill as restoring public access to the science behind listings and exposing litigation spending and fee awards.
