Western Caucus of U.S. senators and representatives issued a 116-page report in 2023 titled "The Endangered Species Act at 50", with a subtitle expressing its primary criticism that "a record of falsified recoveries underscores a lack of scientific integrity in the federal program." Among the faculty expressing views in a University of Pennsylvania report, one drew attention to an underlying shift in national worldviews during the past half-century: The Act "reflects the confidence of mid-20th century liberal politics that any problem can be fixed with legislation based on scientific data," yet pragmatic solutions that require flexibility have been hindered and polarization has become intense. An academic review paper in 2008 reported that the Act had become "a social, legal, and political battleground" and that "the scientific question of whether the ESA works effectively to protect species remains open." Specific challenges and long-term controversies are summarized in this section.
1264:"Fear of failure in conservation" is another factor that contributes to agency and manager hesitancy to undertake recovery actions for which there is no certainty of success. There are two reasons why scientists themselves may abstain from recommending actions. One is fear that making such recommendations may compromise their status as objective researchers whose conclusions can be trusted. A second is fear that a recommended action that is undertaken but then fails may injure their reputation. These fears may be heightened when recommendations pertain to a species for which controversy has developed or one whose population has declined so drastically that any manipulation of the species or its habitat may later be denounced as contributing to its further decline or extinction. Thus there are multiple reasons why recovery programs for some species "may be trapped in a cycle where more resources are allocated to information gathering versus action."

The plan is to be written and published in the customary way, and it continues to be subject to the "five year review" process.

The intent is to deter controversy by building into the plan practices for minimizing harm to listed species and their core habitat needs (including seasonal peaks in use).

Securing landowner pledges of habitat enhancement measures during the planning process can serve to defuse opposition from the public and other stakeholders.

Because wolves are so wide-ranging and can be expected to occasionally prey upon livestock that ranchers legally graze on federal (even wilderness) lands, announcements of intents to restore these predators to particular federal lands in the Rocky Mountain states generated conflicting views at the outset. Ever after, state authority to manage roaming wolves (and authorize takings and hunts) has been controversial, as well.

As a result, the first plant listings occurred in 1977. Fifty years later, significantly more species of plants were listed in the highest category (endangered) than animals: 766 plants and 486 animals.
