The Southwestern Association of Naturalists, an organization of 791 scientists (at time of publication) specializing in the
zoology,
botany, and
ecology of southwestern USA and Mexico, published a resolution in 2008 expressing opposition to the
Mexico–United States barrier "based on sound and accurate scientific knowledge" and its negative impact on "many rare, threatened and endangered species", "particularly endangered mammals such as the
jaguar,
ocelot, jaguarundi, and Sonoran
pronghorn" citing literature within their resolution. Over 2500 scientists from 43 countries (including 1472 from the USA and 616 from Mexico) also published a statement in 2018 stating that the border wall will have "significant consequences for biodiversity" and that "already-built sections of the wall are reducing the area, quality, and connectivity of plant and animal habitats and are compromising more than a century of binational investment in conservation", citing published scientific studies therein. A few patches of good habitat remain in south Texas, despite having been largely destroyed by the construction of the border fence. == Conservation efforts ==
