The "Endangered Species Transparency and Reasonableness Act of 2025" aims to increase transparency and incorporate local data in Endangered Species Act decisions. It requires the publication of data used for species listing decisions online, unless restricted by state law or national security. The bill also mandates the disclosure of federal expenditures related to Endangered Species Act litigation and aligns the awarding of legal fees with existing federal law. Additionally, it ensures that data submitted by State, Tribal, or county governments is considered as "best scientific and commercial data available".
