Ocelots face many threats. They once lived in Texas, Arizona, Louisiana, and Arkansas, but only about 30 individuals now survive in the U.S., although they are still widely distributed across south and central Mexico. How does the construction of a longer/taller border wall impact the conservation of the ocelot?

• Increased habitat destruction and fragmentation.

• Inability to migrate.

• Isolation of U.S. gene pool, resulting in reduced fitness.

• The border wall will not impact ocelot conservation.

• The border wall will impact ocelot conservation in all of the above ways.
