In the shadow of the U.S.-Mexico border fence, jabalinas walk through the San Pedro National Riparian Conservation Area in southeastern Arizona
in August 2008.
These hoofed mammals eat and distribute seeds for several plant species as they roam the borderlands, said Krista Schlyer, leader of a January-February 2009 conservation-photography expedition to the border-fence region.
If the animals are prevented from moving by the U.S. border fence, the plants will lose a crucial step in their reproductive cycle, Schyler said.
Likewise, if jabalinas can't explore their usual range, predators that eat jabalinas—such as jaguars
, Mexican gray wolves, and mountain lions—may also suffer, experts say.
