This legislative proposal aims to amend the Endangered Species Act of 1973 by introducing a new requirement for species listing and delisting determinations. It mandates that the Secretary accept and integrate state-collected data when deciding whether to classify a species as threatened or endangered, or to remove such a classification. The bill, titled the "Local Data for Better Conservation Act," seeks to ensure that information gathered at the state level is formally considered in federal conservation efforts. This provision intends to incorporate more localized and comprehensive data into the decision-making process for protecting and managing species.
